Description

Technical Field

[0001] This utility model belongs to the field of leather production technology, specifically, it relates to an S-type plasticizing oven. Background Technology

[0002] An oven is an essential piece of equipment for manufacturing products such as PU / PVC artificial leather, PU synthetic leather, PVC flooring, PVC three-proof tarpaulin, PVC anti-slip mats, PVC fabric coatings, laminated leather (split-leather or double-layer leather), and latex sponge. Currently, the frame of an oven is made of integral steel and transported as a whole. The cavity of the insulation board is filled with aluminum silicate fiber cotton. This fiber cotton is prone to shrinkage due to vibration, creating space within the insulation board cavity and affecting the insulation effect.

[0003] Existing plasticizing ovens generally adopt a horizontal single-layer layout, typically 10m, 20m, or 30m in length, and simultaneously employ hot oil circulation heating or direct combustion heating within the natural gas oven. Due to the horizontal layout, most of the internal space of these ovens cannot be utilized, resulting in low working efficiency. Therefore, a space-saving and more efficient S-type plasticizing oven is needed. Utility Model Content

[0004] The purpose of this invention is to provide a space-saving and more efficient S-shaped plasticizing oven. By arranging multiple mesh belt conveyors in parallel inside the rectangular box, the products are transported in an S-shaped path inside the rectangular box. This allows each oven to plasticize longer products, saving the floor space of multiple ovens and effectively improving the working efficiency of the plasticizing oven.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An S-shaped plasticizing oven includes a rectangular box body arranged horizontally on the left and right sides. Inside the rectangular box body, an odd number of mesh belt conveyor mechanisms are arranged vertically and parallel to each other, with a minimum of three mesh belt conveyor mechanisms. The conveying direction of all mesh belt conveyor mechanisms is horizontal on the left and right sides. The conveying directions of the odd-numbered mesh belt conveyor mechanisms are all the same, and the conveying directions of the even-numbered mesh belt conveyor mechanisms are all the same. The conveying directions of the even-numbered mesh belt conveyor mechanisms are opposite to those of the odd-numbered mesh belt conveyor mechanisms. All odd-numbered mesh belt conveyor mechanisms, except the bottommost mesh belt conveyor mechanism, have a gap between their right ends and the inner wall of the right side plate of the rectangular box. All even-numbered mesh belt conveyor mechanisms, except the bottommost mesh belt conveyor mechanism, have a product release mechanism at their right ends. All even-numbered mesh belt conveyor mechanisms have a product release mechanism at their left ends.

[0006] A left mounting bracket is provided at the left end of the rectangular box, and a right mounting bracket is provided at the right end of the rectangular box. Several mounting columns are provided between the left and right mounting brackets. The left mounting frame includes a first left column and a first right column, with several first mounting crossbars arranged vertically and parallel to each other between the first left column and the first right column; the right mounting frame includes a second left column and a second right column, with several second mounting crossbars arranged vertically and parallel to each other between the second left column and the second right column.

[0007] The odd-layer mesh belt conveyor mechanism includes a first drive guide roller, a first conveyor mesh belt, and a first deflecting guide roller. The first drive guide roller is mounted on the left mounting frame via a first conveyor frame. A first pressure roller is provided on the first conveyor frame and is located to the lower right of the first drive guide roller. The first deflecting guide roller is mounted on the right mounting frame via a first guide roller frame. A first conveyor motor is mounted on the left mounting frame and is driven by the first drive guide roller. The even-layer mesh belt conveyor mechanism includes a second active guide roller, a second conveyor mesh belt, and a second deflecting guide roller. The second active guide roller is mounted on the right mounting frame via a second conveyor frame. A second pressure roller is provided on the second conveyor frame and is located to the lower left of the first active guide roller. The second deflecting guide roller is mounted on the left mounting frame via a second guide roller frame. A second conveyor motor is mounted on the right mounting frame and is connected to the second active guide roller via a drive.

[0008] Several mesh belt pressure rollers and / or several mesh belt idlers are provided on the left and / or right sides of the mounting column. Among them, some mesh belt idlers are located below the upper mesh belt of the first conveyor mesh belt and are in close contact with the lower surface of the upper mesh belt; some mesh belt idlers are located below the lower mesh belt of the first conveyor mesh belt and are in close contact with the lower surface of the lower mesh belt; some mesh belt idlers are located below the upper mesh belt of the second conveyor mesh belt and are in close contact with the lower surface of the upper mesh belt; some mesh belt pressure rollers are located above the lower mesh belt of the first conveyor mesh belt and are in close contact with the upper surface of the lower mesh belt; and some mesh belt pressure rollers are located above the lower mesh belt of the second conveyor mesh belt and are in close contact with the upper surface of the lower mesh belt.

[0009] Each mesh belt conveyor is equipped with at least one radiant heater between the upper and lower mesh belts. The radiant heater includes a mounting bracket and several heat dissipation pipes mounted on the mounting bracket. The heat dissipation pipes are arranged in the front-to-back direction, and all heat dissipation pipes are arranged in parallel. Adjacent heat dissipation pipes are arranged alternately up and down. The surface of the heat dissipation pipes is provided with heat dissipation fins. The leftmost heat dissipation pipe is connected to an oil inlet pipe, and the rightmost heat dissipation pipe is connected to an oil outlet pipe.

[0010] The product release mechanism includes a mounting plate with a mounting crossbar. The mounting crossbar extends downward to a mounting vertical bar, and a release guide roller is mounted on the mounting vertical bar. The product passes through the release guide roller to reach the mesh belt conveyor mechanism of the next layer.

[0011] A left pressure roller is provided on the right side of the left mounting frame, and is positioned above the lower mesh belt of the second conveyor belt and close to the upper surface of the lower mesh belt. A right pressure roller is provided on the left side of the right mounting frame, and is positioned above the lower mesh belt of the first conveyor belt and close to the upper surface of the lower mesh belt.

[0012] This application features a simple structure, scientific principle, and convenient operation. By setting multiple mesh belt conveyor mechanisms inside a rectangular box, and arranging these multiple mesh belt conveyor mechanisms vertically and horizontally, each plasticizing oven can simultaneously perform plasticizing work on longer lengths of leather, greatly saving floor space and effectively improving the working efficiency of the plasticizing oven. It solves the technical problem that the horizontal layout of existing ovens results in most of the internal space being unusable, leading to low working efficiency of the plasticizing oven.

[0019] like Figure 1-6 As shown, an S-type plasticizing oven includes a rectangular box 1 arranged horizontally on both sides. Insulation plates 2 are provided on each external surface of the rectangular box 1. An odd number of mesh belt conveyor mechanisms are arranged vertically and parallel to each other inside the rectangular box 1, with a minimum of three mesh belt conveyor mechanisms. All mesh belt conveyor mechanisms are arranged horizontally on both sides. The conveying directions of the odd-numbered mesh belt conveyor mechanisms are the same, and the conveying directions of the even-numbered mesh belt conveyor mechanisms are the same, but opposite to those of the odd-numbered mesh belt conveyor mechanisms. Figure 1-4As shown, taking three mesh belt conveyor mechanisms as an example, the conveying direction of the middle layer mesh belt conveyor is horizontal to the left, while the conveying direction of the upper and lower layer mesh belt conveyor mechanisms is to the right. This ensures that the product 29 enters from the upper left of the rectangular box 1 and exits from the lower right of the rectangular box 1, so that the plasticizing oven of this application can be applied to the production line to realize the production line production of leather, thereby improving the production efficiency of leather.

[0020] All odd-numbered layer mesh belt conveyor mechanisms, except the bottom layer, have a gap between their right ends and the inner wall of the right side plate of the rectangular box 1. All even-numbered layer mesh belt conveyor mechanisms, except the bottom layer, have a gap between their left ends and the inner wall of the left side plate of the rectangular box 1. All odd-numbered layer mesh belt conveyor mechanisms, except the bottom layer, have a product 29 release mechanism on their right ends, and even-numbered layer mesh belt conveyor mechanisms have a product 29 release mechanism on their left ends. Figure 1-4 As shown, taking three mesh belt conveyor mechanisms as an example, there is a gap between the right end of the first mesh belt conveyor mechanism and the inner wall of the right side plate of the rectangular box 1, while the right end of the third mesh belt conveyor mechanism does not need to be gapped with the inner wall of the right side plate of the rectangular box 1 because the third mesh belt conveyor mechanism directly delivers the product 29 to the next station to facilitate the conveying of the product 29.

[0021] A left mounting bracket is provided at the left end of the rectangular box 1, and a right mounting bracket is provided at the right end of the rectangular box 1. Several mounting columns 3 are provided between the left and right mounting brackets. The left mounting bracket includes a first left column 4 and a first right column 5. Several first mounting crossbars 236 are arranged vertically and parallel between the first left column 4 and the first right column 5. The right mounting bracket includes a second left column 87 and a second right column. Several second mounting crossbars 9 are arranged vertically and parallel between the second left column 87 and the second right column.

[0022] The odd-layer mesh belt conveyor mechanism includes a first drive guide roller 10, a first conveyor mesh belt 11, and a first deflecting guide roller 12. The first drive guide roller 10 is mounted on the left mounting frame via a first conveyor frame. A first pressure roller 13 is provided on the first conveyor frame and is located to the lower right of the first drive guide roller 10. The first deflecting guide roller 12 is mounted on the right mounting frame via a first guide roller frame. A first conveyor motor is mounted on the left mounting frame and is driven by the first drive guide roller 10. The even-layer mesh belt conveyor mechanism includes a second active guide roller 14, a second conveyor mesh belt 15, and a second deflecting guide roller 16. The second active guide roller 14 is mounted on the right mounting frame via a second conveyor frame. A second pressure roller 17 is provided on the second conveyor frame and is located to the lower left of the first active guide roller 10. The second deflecting guide roller 16 is mounted on the left mounting frame via a second guide roller frame. A second conveyor motor is mounted on the right mounting frame and is connected to the second active guide roller 14 via a drive.

[0023] Several mesh belt pressure rollers and / or several mesh belt idlers are provided on the left and / or right sides of the mounting column 3. Among them, mesh belt idlers 30 are located below the upper mesh belt of the first conveyor mesh belt 11 and are in close contact with the lower surface of the upper mesh belt; mesh belt idlers 31 are located below the lower mesh belt of the first conveyor mesh belt 11 and are in close contact with the lower surface of the lower mesh belt; mesh belt idlers 33 are located below the upper mesh belt of the second conveyor mesh belt 15 and are in close contact with the lower surface of the upper mesh belt; mesh belt idlers 34 are located below the lower mesh belt of the second conveyor mesh belt 15 and are in close contact with the lower surface of the lower mesh belt; mesh belt pressure rollers 32 and 35 are located above the lower mesh belt of the first conveyor mesh belt 11 and are in close contact with the upper surface of the lower mesh belt; and mesh belt pressure rollers 35 are located above the lower mesh belt of the second conveyor mesh belt 15 and are in close contact with the upper surface of the lower mesh belt.

[0024] At least one radiant heater 18 is installed between the upper and lower mesh belts of each mesh belt conveyor mechanism. The radiant heater 18 includes a mounting bracket 19 and several heat dissipation pipes 20 mounted on the mounting bracket 19. The heat dissipation pipes 20 are arranged in a front-to-back direction, and all heat dissipation pipes 20 are arranged parallel to each other. Adjacent heat dissipation pipes 20 are alternately arranged vertically. The surface of the heat dissipation pipes 20 is provided with heat dissipation fins 21. The leftmost heat dissipation pipe 20 is connected to an oil inlet pipe, and the rightmost heat dissipation pipe 20 is connected to an oil outlet pipe. Adjacent heat dissipation pipes 20 are connected by U-shaped pipes. The heat dissipation pipes 20 are made of seamless steel pipes. The heat dissipation fins 21 are supported by aluminum tubes 26 that are sleeved on the heat dissipation pipes 20 using a rolling process and are tightly integrated with the outer surface of the heat dissipation pipes 20. The heat dissipation fins 21 of the radiant heater 18 are manufactured using rolling technology, that is, the aluminum tubes 26 are sleeved on the seamless steel pipes and rolled by a mold. The aluminum tubes 26 are rolled into fins with uniform and equidistant spacing. During the rolling process, the aluminum tube 26 is tightly bonded to the surface of the seamless steel tube, which eliminates the gap between the fins and the heat dissipation tube 20 and improves the heat conduction effect. A pressure test is also required for the radiant heater 18: the radiant heater 18 is placed on a pressure test bench to check for leakage. The radiant heater 18 should be subjected to a pressure of 0.5 MPa for 10 minutes without any leakage (the online operating pressure of hot oil is ≤0.3 MPa).

[0025] The product 29 release mechanism includes a mounting plate 22, on which a mounting crossbar 23 is mounted. A mounting vertical bar 24 extends downward from the mounting crossbar 23. A release guide roller 25 is mounted on the mounting vertical bar 24. The product 29 passes through the release guide roller 25 to reach the next layer of the mesh belt conveyor mechanism.

[0026] A left pressure roller 27 is provided on the right side of the left mounting frame. The left roller is positioned above the lower mesh belt of the second conveyor belt 15 and is in close contact with the upper surface of the lower mesh belt. A right pressure roller 28 is provided on the left side of the right mounting frame. The right pressure roller 28 is positioned above the lower mesh belt of the first conveyor belt 11 and is in close contact with the upper surface of the lower mesh belt.

[0027] like Figure 1-4 As shown, taking three mesh belt conveyor mechanisms as an example, in the specific operation of this application, the product 29 is conveyed from the left end of the first layer mesh belt conveyor mechanism to the right end, then passes through the release guide roller 25 of the product 29 release mechanism to the right end of the middle layer mesh belt conveyor mechanism, and then is conveyed to the left end of the middle layer mesh belt conveyor mechanism. It then passes through the release guide roller 25 of the product 29 release mechanism located at the left end of the middle layer mesh belt conveyor mechanism to reach the third layer mesh belt conveyor mechanism, and then from the left end of the third layer mesh belt conveyor mechanism to the right end of the third layer mesh belt conveyor mechanism and finally exits the plasticizing oven. During this process, the radiant heater 18 of each layer heats the product 29. Heat is used to improve the plasticizing effect. In this S-shaped plasticizing oven, the running length of the conveyor belt mechanism of each layer of the product 29 is 10m, which is equivalent to 30m of a horizontal oven, and the volume is the same. This not only reduces the floor space and saves resources, but also reduces the floor space and saves resources. In addition, a horizontal oven with a unit length of 5m requires a 4KW blower on each side. A single oven with a length of 10m requires four blowers. However, this application uses a radiant heater 18 for heating and equips each layer with a radiant heater 18, eliminating the need for blowers. Therefore, a 10m oven saves 16KW of motor capacity. If the oven length is 20m, the motor capacity is reduced by 32KW, resulting in significant energy savings.

[0028] This application features a simple structure, scientific principle, and convenient operation. By setting multiple mesh belt conveyor mechanisms inside the rectangular box 1 and arranging them in parallel vertically, each plasticizing oven can simultaneously perform plasticizing work on longer lengths of leather, greatly saving floor space and effectively improving the working efficiency of the plasticizing oven. This solves the technical problem that existing ovens, due to their horizontal layout, cannot utilize most of the internal space, resulting in low working efficiency.

[0029] The above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the utility model without departing from the spirit and scope of the utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
