Description

Technical Field

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

[0002] Rubber is an elastic polymer that can be obtained from the sap of some plants or is man-made. Both have numerous applications and products, such as tires and gaskets, making it an important economic crop. Rubber is classified into natural rubber and synthetic rubber according to its raw materials, and into block raw rubber, latex, liquid rubber, and powdered rubber according to its form. During the production of rubber products, some high-temperature rubber blanks are produced. Current technology involves placing the rubber blanks on an open platform for heat dissipation, but the heat dissipation efficiency is low. In addition, sometimes the rubber blanks are placed in a cold water tank for cooling, but after cooling in a cold water tank, there is a lot of moisture on the rubber blanks, which affects the next production process, thus affecting production efficiency and quality. Utility Model Content

[0003] This invention addresses the technical problem of low cooling efficiency for rubber blanks generated during the production of existing rubber products. It provides a cooling and drying device for rubber blanks, comprising a horizontally arranged cooling box with a vertically arranged partition in the middle of the interior, dividing the cooling box into a cooling section and a draining section. In use, cooling water is injected into the cooling section. The top of the cooling box is open. A first conveying mechanism is located at the left end of the interior of the cooling box, and a second conveying mechanism with the same structure as the first conveying mechanism is located at the right end. Both the first and second conveying mechanisms have evenly spaced baffles on their conveyor belts. Both include a first horizontal section within the cooling box, with an upward-sloping section at its right end. The top of the inclined section connects to the second horizontal section. The left end of the first horizontal section of the second conveying mechanism is located below the second horizontal section of the first conveying mechanism. During operation, the first horizontal section of the first conveying mechanism is submerged in water. The first horizontal section carries the rubber blank, cooled by the water, out of the cooling water, then through the inclined section and onto the second horizontal section before falling onto the first horizontal section of the second conveying mechanism. During this process, the rubber blank tumbles. Several first fans are installed above the inclined part of the first conveying mechanism. The first fans are installed to further dissipate heat and accelerate the falling of water droplets on the rubber blank. Several second fans are installed above the inclined part of the second conveying mechanism. The second fans are installed to dissipate heat. Both the first and second fans are fixed to the inclined part by fan brackets. A high-pressure blowing mechanism is provided above the inclined part of the second conveying mechanism. The jet nozzle of the high-pressure blowing mechanism faces the inclined part. The high-pressure blowing mechanism includes a horizontally arranged support plate, which is fixed to one side of the cooling box. Several vertically arranged support rods are fixed on the support plate. An inclined main vent pipe is provided above the support rods. The main vent pipe is parallel to the inclined part and is fixed to the top of the support rods. Several branch vent pipes are provided above the inclined part, which are parallel to the inclined part and spaced apart. One end of the branch vent pipe is connected to the main vent pipe, and the bottom end of each branch vent pipe is provided with several jet nozzles. A connector is provided on the main vent pipe. In use, the main vent pipe is connected to the high-pressure air pump through the connector. The high-pressure air pump delivers high-pressure gas to the main vent pipe and the branch vent pipes, and then sprays it out from the jet nozzles at the bottom of the branch vent pipes. The high-pressure gas blows off the water droplets on the rubber blank.The cooling box has a frame arranged front and rear on its right end. From top to bottom, the frame has a first conveyor mechanism, a second conveyor mechanism, and a third conveyor mechanism evenly spaced. The rear end of the first conveyor mechanism is located below the second horizontal section of the second conveyor mechanism. The front end of the second conveyor mechanism extends forward beyond the front end of the first conveyor mechanism, and the rear end of the third conveyor mechanism extends backward beyond the rear end of the second conveyor mechanism. The first, second, and third conveyor mechanisms have identical structures, each including a conveyor mechanism support frame. The support frame is fixed to the frame and has several conveyor rollers and a conveyor motor. The conveyor rollers are connected to the conveyor motors, and a conveyor belt is installed between the rollers. The conveyor belt has several through holes for conveying... The motor is connected to the power supply and PLC controller via a cable, starting the conveyor motor. The conveyor motor drives the conveyor belt to rotate, and the blanks on the second conveyor mechanism fall to the rear end of the first conveyor mechanism. The first conveyor mechanism transports the rubber blanks to the front end of the second conveyor mechanism, and then the second conveyor mechanism transports the rubber blanks to the rear end of the third conveyor mechanism. Under the action of the third conveyor mechanism, the rubber blanks are transported to the front end of the third conveyor mechanism and then fall into the collection box below the left end of the third conveyor mechanism (not shown in the attached diagram of the instruction manual). This setting can increase the drying time of the rubber blanks and tumble the rubber blanks, which is convenient for drying the bottom surface of the rubber blanks, thus improving drying efficiency and drying quality. A drying mechanism is provided on the frame above the first conveyor mechanism. The drying mechanism includes a drying chamber fixed to the upper end of the frame. The drying chamber has several heating rods, and a third fan is located at the upper end of the drying chamber. The third fan is connected to the power supply and PLC controller via a cable, and when the third fan is started, it blows warm air onto the first, second, and third conveyor mechanisms.

[0004] Preferably, the first conveying mechanism and the second conveying mechanism include a conveyor belt frame, which is fixed to the bottom of the cooling box by support legs. A conveyor roller is rotatably mounted on the conveyor belt frame, and a conveyor belt is provided between the conveyor rollers. A conveyor motor is fixed to the outside of the conveyor belt frame, and the conveyor motor is connected to the conveyor rollers in a transmission connection.

[0005] Preferably, the first conveying mechanism is disposed in the cooling section, and the second conveying mechanism is disposed in the draining section.

[0006] Preferably, the top of the drying chamber is detachably provided with a cover, and the cover has a number of evenly spaced ventilation holes.

[0007] Preferably, the frame is provided with a baffle plate that serves to stop the material.

[0008] The above scheme has the following advantages: The first, second, and third conveying mechanisms increase the drying time of the rubber blanks and tumble them, facilitating drying of the bottom surface and improving drying efficiency and quality. The first conveying mechanism transports the rubber blanks out of the cooling box and to the left end of the second conveying mechanism, improving production efficiency compared to manual retrieval. The high-pressure blowing mechanism delivers high-pressure gas to the main and branch ventilation pipes via a high-pressure air pump, which then sprays it from the nozzle at the bottom of the branch ventilation pipe, blowing off water droplets from the rubber blanks.

A vertically arranged partition 11 is provided in the middle of the interior of the cooling box 1, dividing the cooling box 1 into a cooling section 12 and a draining section 13. In use, cooling water is injected into the cooling section 12. The top of the cooling box 1 is open. A first conveying mechanism 2 is provided at the left end of the interior of the cooling box 1, and a second conveying mechanism 3 with the same structure as the first conveying mechanism 2 is provided at the right end of the interior of the cooling box 1. Both the conveyor belts 22 of the first conveying mechanism 2 and the second conveying mechanism 3 are provided with evenly spaced baffles 24. Both include a first horizontal section 26 disposed inside the cooling box 1. The right end of the first horizontal section 26 is an upwardly inclined section 27. The top end of the inclined section 27 is connected to the second horizontal section 28. The left end of the first horizontal section 26 of the second conveying mechanism 3 is disposed below the second horizontal section 28 on the first conveying mechanism 2. During operation, the first horizontal section 26 of the first conveying mechanism 2 is disposed in water. The first horizontal section 26 carries the rubber blank after it has been cooled by the cold water out of the cooling water, and then conveys it through the inclined section 27 to the second horizontal section 28 before falling onto the first horizontal section 26 of the second conveying mechanism 3. During this process, the rubber blank rolls, and the side of the rubber blank that was previously facing down is removed from the bottom. Several first fans 25 are installed above the inclined portion 27 of the first conveying mechanism 2. The first fans 25 serve to further dissipate heat and accelerate the falling of water droplets from the rubber blank. Several second fans 31 are installed above the inclined portion 27 of the second conveying mechanism 3. The second fans 31 also serve to dissipate heat. Both the first fans 25 and the second fans 31 are fixed to the inclined portion 27 by fan brackets 251. A high-pressure blowing mechanism 4 is installed above the inclined portion 27 of the second conveying mechanism 3. The jet nozzles of the high-pressure blowing mechanism 4 face the inclined portion 27. The high-pressure blowing mechanism 4 includes a horizontally arranged support plate 41, which is fixed to one side of the cooling box 1. Several vertically arranged support rods 42 are fixed on the support plate 41. An inclined main vent pipe 43 is installed above the support rods 42. The main vent pipe 43 is parallel to the inclined portion 27 and is fixed to the top of the support rods 42. Several second fans 31 are installed above the inclined portion 27. Branch vent pipes 44 are arranged parallel to and spaced apart from the inclined part 27. One end of the branch vent pipe 44 is connected to the main vent pipe 43, and the bottom end of each branch vent pipe 44 is provided with several air jets (not shown in the attached drawings of the instruction manual). The main vent pipe 43 is provided with a connector 45. In use, the main vent pipe 43 is connected to the high-pressure air pump through the connector 45. The high-pressure air pump delivers high-pressure gas to the main vent pipe 43 and the branch vent pipes 44, and then sprays it out from the air jets at the bottom end of the branch vent pipes 44. The high-pressure gas blows the water droplets off the rubber blank.The cooling box 1 has a frame 5 arranged front to back on the right end. The frame 5 has a first conveying mechanism 51, a second conveying mechanism 52, and a third conveying mechanism 53 evenly spaced from top to bottom. The rear end of the first conveying mechanism 51 is located below the second horizontal part 28 of the second conveying mechanism 3. The front end of the second conveying mechanism 52 extends forward beyond the front end of the first conveying mechanism 51, and the rear end of the third conveying mechanism 53 extends backward beyond the rear end of the second conveying mechanism 52. The first, second, and third conveying mechanisms 51, 52, and 53 have the same structure, each including a conveying mechanism support. The conveying mechanism support is fixed to the frame 5, and the support has several conveying rollers and a conveying motor 55. The conveying rollers are connected to the conveying motor 55, and a conveyor belt 54 is provided between the rollers. The conveyor belt 54 has several through holes. To facilitate gas passage, the conveyor motor 55 is connected to the power supply and PLC controller via a cable. Starting the conveyor motor 55 causes the conveyor belt 54 to rotate, and the blank on the second conveyor mechanism 3 falls to the rear end of the first conveyor mechanism 51. The first conveyor mechanism 51 transports the rubber blank to the front end of the second conveyor mechanism 52, and then the second conveyor mechanism 52 transports the rubber blank to the rear end of the third conveyor mechanism 53. Under the action of the third conveyor mechanism 53, the rubber blank is transported to the front end of the third conveyor mechanism 53 and then falls into the collection box below the left end of the third conveyor mechanism 53 (not shown in the attached diagram). This setup increases the drying time of the rubber blank and allows it to be tumbled, facilitating drying of the bottom surface of the rubber blank and improving drying efficiency and quality. A drying mechanism 6 is provided on the frame 5 above the first conveying mechanism 51. The drying mechanism 6 includes a drying chamber 61 fixed to the upper end of the frame 5. The drying chamber 61 is provided with several heating rods (not shown in the attached drawings of the instruction manual, which belong to the prior art). A third fan is provided at the upper end of the interior of the drying chamber 61. The third fan is connected to the power supply and PLC controller through a cable. When the third fan is started, it blows warm air onto the first conveying mechanism 51, the second conveying mechanism 52 and the third conveying mechanism 53.

[0012] Preferably, the first conveying mechanism 2 and the second conveying mechanism 3 include a conveyor belt frame 21, which is fixed to the bottom of the cooling box 1 by support legs. A conveyor roller is rotatably mounted on the conveyor belt frame 21, and a conveyor belt 22 is provided between the conveyor rollers. A conveyor motor 23 is fixed on the outside of the conveyor belt frame 21, and the conveyor motor 23 is connected to the conveyor rollers in a transmission connection.

[0013] Preferably, the first conveying mechanism 2 is disposed in the cooling section 12, and the second conveying mechanism 3 is disposed in the draining section 13.

[0014] Preferably, the top of the drying chamber 61 is detachably provided with a cover 62, and the cover 62 has a plurality of evenly spaced ventilation holes.

[0015] Preferably, the frame 5 is provided with a baffle plate 56 that serves to stop the material.

[0016] Usage process: In use, cooling water is first injected into the cooling section 12. The first horizontal section 26 of the first conveying mechanism 2 is submerged in the water. The first horizontal section 26 carries the rubber blank, which has been cooled by the cooling water, out of the water. Then, it is conveyed through the inclined section 27 to the second horizontal section 28 and falls onto the first horizontal section 26 of the second conveying mechanism 3. During this process, the rubber blank tumbles, and the previously downward-facing side of the rubber blank detaches from the bottom. Several first fans 25 are provided above the inclined section 27 of the first conveying mechanism 2. The first fans 25 are set to further dissipate heat and accelerate the falling of water droplets on the rubber blank. Several second fans 31 are provided above the inclined section 27 of the second conveying mechanism 3. The second fans 31 are also set to dissipate heat. The main vent pipe 43 is connected to the high-pressure air pump through the connector 45. A high-pressure air pump delivers high-pressure gas to the main vent pipe 43 and the branch vent pipe 44, and then sprays it out from the jet nozzle at the bottom of the branch vent pipe 44. The high-pressure gas blows off the water droplets on the rubber blank. The blank on the second conveying mechanism 3 falls to the rear end of the first conveying mechanism 51. The first conveying mechanism 51 conveys the rubber blank to the front end of the second conveying mechanism 52, and then the second conveying mechanism 52 conveys the rubber blank to the rear end of the third conveying mechanism 53. Under the action of the third conveying mechanism 53, the rubber blank is conveyed to the front end of the third conveying mechanism 53, and then falls into the collection box below the left end of the third conveying mechanism 53 (not shown in the attached diagram of the instruction manual). This setting can increase the drying time of the rubber blank and can tumble the rubber blank, which is convenient for drying the bottom surface of the rubber blank, thereby improving the drying efficiency and drying quality. The third fan is started, and the third fan blows warm air onto the rubber blanks on the first conveyor mechanism 51, the second conveyor mechanism 52 and the third conveyor mechanism 53 to further dry the surface of the rubber blanks.
