Description

Technical Field

[0001] This utility model belongs to the field of rubber processing technology, and in particular relates to a cooling and conveying device for compounded rubber sheets. Background Technology

[0002] Rubber is a polymer material, mainly composed of natural rubber or synthetic rubber. It has a wide range of industrial applications, such as in automobile tires. During rubber production, rubber materials need to be mixed to obtain higher-performance cured rubber. Specifically, mixing stretches the molecular structure of the rubber, significantly improving its elasticity, tensile strength, and other properties.

[0003] Because the temperature of the rubber rises after mixing, rubber at high temperatures not only undergoes irreversible deformation but is also prone to tearing and breakage. Therefore, the rubber needs to be cooled during transport, mostly through natural cooling. However, in actual production, because cooling requires sufficient time, current technology can only increase the transport path, such as by lengthening the conveyor belt, to transport high-temperature rubber. But this method obviously occupies a lot of horizontal space in the workshop, making it impossible to extend the transport path of the rubber sufficiently within the effective production workshop, thus limiting the cooling effect.

[0004] Air cooling can improve the cooling speed of rubber, but similarly, when faced with high-temperature rubber being fed at high speed, if it is not transferred in time, the rubber is prone to accumulate at the discharge port of the equipment. Although air cooling is highly efficient, it is simply not enough to cool the rubber sufficiently in a short time.

[0005] Therefore, if sufficient rubber transport distance is maintained during the production process, while not occupying too much horizontal space in the workshop and accelerating the cooling speed of the rubber, the cooling speed of the rubber can be greatly improved, and the production efficiency of the rubber can be significantly increased. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a cooling and conveying device for compounded rubber sheets.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A cooling and conveying device for compounded rubber sheets includes a frame, in which a rubber sheet air-cooling conveying mechanism is installed symmetrically arranged vertically.

[0009] The air-cooled conveying mechanism for rubber sheets includes an upper conveyor and a lower conveyor that is staggered with the upper conveyor.

[0010] The mixed rubber sheet cooling and conveying device also includes an air-cooling mechanism, which includes air-cooling pipe assemblies arranged at intervals. Each air-cooling pipe assembly includes several air-cooling pipes located between the upper conveyor and the lower conveyor. Air-cooling through holes are opened at the top and bottom of the air-cooling pipes respectively.

[0011] The air-cooled pipe assembly also includes a pipe frame structure that connects several air-cooled pipes, and the pipe frame structure is connected to a pump-cooled air pipe.

[0012] The mixed rubber sheet cooling and conveying device also includes a rubber pushing mechanism disposed between the rubber sheet air-cooling and conveying mechanisms. The rubber sheet is pushed from the upper position of the rubber sheet air-cooling and conveying mechanism to the lower position of the rubber sheet air-cooling and conveying mechanism through the rubber pushing mechanism.

[0013] Preferably, both the upper conveyor and the lower conveyor include conveyor belt drums arranged on both sides, and a conveyor belt is installed between the conveyor belt drums;

[0014] A motor is installed on the conveyor belt drum;

[0015] The two ends of the conveyor belt drum are respectively rotatably connected to a conveyor frame.

[0016] Preferably, the frame includes frame plates spaced apart on both sides, and a base is fixedly connected between the bottoms of the frame plates;

[0017] An irregularly shaped inner fixing frame is installed on the inner side wall of the frame plate, and the transmission machine frame is fixedly installed on the inner fixing frame by several mounting rods.

[0018] Preferably, the internal fixing frame is detachably mounted on the frame plate by a number of bolts;

[0019] The inner fixing frame has several fixing frame beams, and the mounting rod is welded and fixed to the fixing frame beams.

[0020] Preferably, the conveyor belt has several strip-shaped heat dissipation holes.

[0021] Preferably, the pipe rack structure includes a horizontally arranged branch pipe, and the pump cooling air pipe is connected to the branch pipe;

[0022] The branch pipes are respectively connected to ventilation and cooling pipes.

[0023] Preferably, the rubber pushing mechanism includes a pushing rod rotatably connected between the frame plates, and a rotary motor is installed at one end of the pushing rod;

[0024] The push rod is fixedly mounted with a push arm wheel structure containing several push rubber plates.

[0025] Preferably, the push arm wheel structure includes a push arm fixed on a push rod, and a push wheel is rotatably connected to the end of the push arm.

[0026] Preferably, the longitudinal cross-sectional shape of the frame plate is trapezoidal;

[0027] A T-shaped frame is welded to the bottom of the frame plate, and the T-shaped frame is fastened to the base by a number of mounting bolts.

[0028] This utility model has the following beneficial effects:

[0029] 1. During the working process, the rubber sheet is transported from the top upper conveyor to the discharge end. Then, due to the staggered arrangement of the upper conveyor and the lower conveyor, the rubber falls onto the lower conveyor. Subsequently, the rubber continues to fall onto the upper and lower conveyors below, achieving four layers of conveying. Therefore, the conveying path of the rubber is greatly increased, allowing sufficient time for the rubber to cool down, while not affecting the speed at which the high-temperature rubber is discharged from the production equipment.

[0030] 2. During the air-cooling process, cooling air is pumped upwards and downwards from the top and bottom of the air-cooling pipes, respectively, to dissipate heat from the rubber on the conveyor belt. Because a layered cooling method is used, the cooling speed is fast and the cooling efficiency is high.

[0031] 3. During operation, as the upper rubber sheet air-cooling conveyor moves from the upper position to the lower position, the rotating motor drives the pusher arm's push wheel inward, pushing the rubber sheet onto the conveyor belt of the lower rubber sheet air-cooling conveyor. This method ensures a smooth transition of the rubber during transport. Attached Figure Description

[0042] Example 1

[0043] like Figure 1-5 As shown, a cooling and conveying device for compounded rubber sheets includes a frame 5. The specific structure of the frame 5 is as follows: the frame 5 includes frame plates spaced apart on both sides, and a base is fixedly connected between the bottoms of the frame plates. Specifically, the longitudinal cross-sectional shape of the frame plates is trapezoidal; a T-shaped frame is welded to the bottom of the frame plates, and the T-shaped frame is fastened to the base by a number of mounting bolts.

[0044] The aforementioned frame 5 is equipped with a symmetrically arranged rubber sheet air-cooling conveyor mechanism. Specifically, by arranging the symmetrically arranged rubber sheet air-cooling conveyor mechanism in the vertical space, a sufficient conveying path length for the rubber is maintained to achieve adequate cooling of the rubber while reducing the horizontal space occupied in the workshop.

[0045] Specifically, the rubber sheet air-cooled conveying mechanism includes an upper conveyor 1 and a lower conveyor 2 that is staggered with the upper conveyor 1.

[0046] Therefore, the two rubber sheet air-cooled conveyor mechanisms form a four-layer conveyor arranged vertically, which enables the rubber to be fully cooled during the four-layer conveying process.

[0047] Specifically, both the upper conveyor 1 and the lower conveyor 2 include conveyor belt drums 11 arranged on both sides, with a conveyor belt 12 installed between the conveyor belt drums 11; a motor 13 is installed on the conveyor belt drums 11. In the conventional manner, the motor 13 is fixedly installed on the following mounting bracket.

[0048] Meanwhile, in the existing manner, a conveyor frame 14 is rotatably connected between the two ends of the conveyor belt drum 11. Specifically, in the same way as the existing rotatable connection method, a rotating shaft is installed on the conveyor belt drum 11 and rotatably connected to the conveyor frame 14, and a matching bearing is installed on the corresponding conveyor frame 14.

[0049] During operation, the rubber sheet is conveyed from the uppermost conveyor 1 to the discharge end. Then, because the upper conveyor 1 is staggered with the lower conveyor 2, the rubber falls onto the lower conveyor 2. Subsequently, the rubber continues to fall onto the upper conveyor 1 and the lower conveyor 2 below, achieving four-layer conveying. Therefore, the conveying path of the rubber is greatly increased, allowing the rubber to cool down for a sufficient time without affecting the speed at which the high-temperature rubber is discharged from the production equipment.

[0050] An irregularly shaped inner fixing frame 6 is installed on the inner wall of the frame plate (because the conveyors are staggered, the inner fixing frame 6 needs to correspond to the position of the conveyor, so it is irregularly shaped). The conveyor frame 14 is fixedly installed on the inner fixing frame 6 by several mounting rods 61.

[0051] Specifically, the inner fixing frame 6 has several fixing frame beams, and the mounting rod 61 is welded and fixed to the fixing frame beams.

[0052] In order to facilitate the disassembly of the conveyor from the frame 5 during operation, and to facilitate cleaning of the conveyor belt 12, the inner fixing frame 6 is detachably installed on the frame plate by several bolts in the existing manner.

[0053] Example 2

[0054] like Figure 1-5As shown, based on the structure of Embodiment 1, this embodiment, in order to fully cool the rubber during the rubber conveying process, further includes an air-cooling mechanism in the above-mentioned mixed rubber sheet cooling and conveying device. The air-cooling mechanism includes air-cooling pipe assemblies 4 spaced vertically. Each air-cooling pipe assembly 4 includes several air-cooling pipes 41 located between the upper conveyor 1 and the lower conveyor 2. Air-cooling through holes 411 are respectively opened at the top and bottom of each air-cooling pipe 41. The air-cooling through holes 411 are strip-shaped, enabling cooling air to be pumped upwards and downwards from the top and bottom of the air-cooling pipes 41 during the air-cooling process, thereby dissipating heat from the rubber on the conveyor belt 12.

[0055] Meanwhile, in order to improve the heat dissipation effect, the above-mentioned conveyor belt 12 is provided with a number of strip-shaped heat dissipation holes A, so that the cooling airflow can come into contact with the rubber from the heat dissipation hole A position.

[0056] The aforementioned air-cooled pipe 41 assembly 4 also includes a pipe rack structure 42 that connects a plurality of air-cooled pipes 41, and the pipe rack structure 42 is connected to a pump-cooled air pipe 421.

[0057] Specifically, the pipe rack structure includes horizontally arranged branch pipes, and the pump cooling air duct is connected to the branch pipes; the branch pipes are respectively connected to ventilation cooling ducts 41. During operation, the pump cooling air duct 421 is connected to a fan (such as a blower) to pump the cooling airflow, as is the existing method. This method achieves sufficient cooling of the conveyed rubber. Because a layered cooling method is used during the cooling process, the cooling speed is fast and the cooling efficiency is high.

[0058] Example 3

[0059] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, when rubber enters the rubber sheet air-cooling transmission mechanism from the upper position to the lower position, and the upper and lower rubber sheet air-cooling transmission mechanisms are symmetrically arranged, the lower conveyor 2 at the upper position and the upper conveyor 1 at the lower position are aligned. Therefore, in order to ensure that the rubber can smoothly transition from the lower conveyor 2 to the upper conveyor 1, the above-mentioned mixed rubber sheet cooling transmission device also includes a rubber pushing mechanism 3 arranged between the rubber sheet air-cooling transmission mechanisms.

[0060] Specifically, the rubber pushing mechanism 3 includes a pushing rod 32 rotatably connected between the frame plates, and a rotary motor 31 is mounted on one end of the pushing rod 32. Similar to existing methods, the output shaft of the rotary motor 31 is fixedly mounted on the pushing rod 32, and the pushing rod 32 is rotatably connected to the frame 5. The motor body of the rotary motor 31 is fixedly mounted on the frame 5.

[0061] Meanwhile, a push arm wheel structure consisting of several pushing rubber plates is fixedly installed on the push rod 32. The push arm wheel structure includes a push arm 33 fixed on the push rod 32, and a push wheel 34 is rotatably connected to the end of the push arm 33.

[0062] During operation, as the upper rubber sheet air-cooling conveyor moves from the upper position to the lower position, the rotating motor 31 drives the rotating rod 32 to push the pusher wheel 34 on the push arm 33 inward, causing the rubber sheet to fall onto the conveyor belt of the lower rubber sheet air-cooling conveyor. This method ensures a smooth transition of the rubber during transmission.

[0063] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
