Description

Technical Field

[0001] The utility model relates to the technical field of traction rollers, in particular to a traction roller with a cooling structure. Background Art

[0002] The traction roller is an important component of the traction machine, and is mainly used to traction and convey materials. The traction roller is usually made of wear-resistant, pressure-resistant, and corrosion-resistant materials, has greater rigidity and good stability, and can withstand greater traction and impact forces. For example, the publication number CN217729364U is a traction roller for waterproof roll production that can be automatically cleaned, including: an upper roller of the traction roller; a lower roller of the traction roller, which is arranged below the upper roller of the traction roller, and the central axis is parallel to the central axis of the upper roller of the traction roller; a distance sensor, which is used to measure the distance from the fixed position to the surface of the upper roller of the traction roller; a cleaning mechanism, including a scraper and a driving part connected to the scraper; the end of the scraper is parallel to the roller surface of the upper roller of the traction roller; the driving part is used to drive the scraper to move closer to or away from the roller surface of the upper roller of the traction roller; a controller, which is electrically connected to the distance sensor and the driving part, respectively, and is used to control the driving part according to the signal of the distance sensor. The traction roller monitors the diameter of the upper roller of the traction roller in real time. When the diameter of the upper roller of the traction roller is greater than the set value, the cleaning mechanism is automatically adjusted to clean the surface of the upper roller of the traction roller; at the same time, the height of the lower roller surface of the traction roller is adjusted to maintain the stability of the gap between the upper roller and the lower roller, thereby ensuring that the friction force of the traction roller on the rubber film remains unchanged during the production process.

[0003] When the existing traction roller is in use, it is installed in the traction machine, so it needs to continuously transport or pull the material. During the continuous transportation process, the temperature of the traction roller will increase due to the friction between the material. If it is used continuously, it will cause damage to the material. Therefore, we have made improvements to this and proposed a traction roller with a cooling structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a traction roller with a cooling structure, which can effectively solve the problem that the existing traction roller is damaged due to temperature increase during continuous use.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A traction roller with a cooling structure comprises a traction roller body, extension rods are installed at both ends of the traction roller body, a rotating shaft for connecting to a bearing seat is installed on the extension rod body, a cooling component for fluid coolant is arranged inside the traction roller body, and a water storage tank and a delivery pump for circulating coolant are connected to both ends of the cooling component.

[0007] Preferably, the cooling assembly comprises a plurality of cooling channels, and the cooling channels are respectively opened inside the traction roller body, and both sides of each cooling channel are respectively provided with extended grooves for increasing the cooling area.

[0008] Preferably, a discharge groove for discharging coolant is provided on one side of the traction roller body, a cavity for receiving coolant is provided on the other side of the traction roller body, a guide slope is provided inside the cavity, and the cooling channel is communicated with the discharge groove and the cavity.

[0009] Preferably, a connecting hole is provided inside the extension rod, a rotating groove is provided inside the connecting hole, a connecting sleeve is provided inside the rotating groove, and a sealing gasket is provided between the connecting sleeve and the rotating groove.

[0010] Preferably, one side of the connecting sleeve is connected to a water inlet pipe, and the other side of the connecting sleeve is connected to a drain pipe.

[0011] Preferably, a delivery pump is fixedly installed at the water outlet of the water storage tank.

[0012] Preferably, the water inlet pipe is connected to the water outlet of the delivery pump, and the water outlet pipe is connected to the water inlet of the water storage tank.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) The coolant enters the water inlet pipe and is connected to the connecting sleeve by a rotating groove, so that the normal inflow and outflow of the coolant will not be affected when the traction roller body continues to rotate. When the coolant enters the cavity, the traction roller body continues to rotate, so that the coolant enters the corresponding cooling channel under the guidance of the guide slope to achieve cooling of the traction roller body. In order to increase the cooling area, extended grooves are opened on both sides of the cooling channel, so that the contact area between the coolant and the heat source can be increased, further improving the cooling effect. After cooling, the coolant will enter the discharge groove to collect the coolant, and finally the coolant after heat exchange will be discharged through the drain pipe.

[0015] (2) By starting the delivery pump, the coolant stored in the water tank can be pumped out and then transferred to the water inlet pipe to realize the liquid supply operation, so that the coolant enters the cooling assembly to cool the traction roller body, thereby preventing the traction roller body from being overheated and affecting the material. After cooling is completed, the coolant will be discharged from the drain pipe, and finally, under the guidance of the drain pipe, the coolant will flow back to the water tank, thereby realizing continuous cooling treatment and further ensuring the current temperature of the traction roller body. The present application requires the use of multiple traction roller bodies, and multiple traction roller bodies can be connected to the water tank through the drain pipe and the water inlet pipe, so that a single water tank can be used for multiple traction roller bodies, which is convenient for application in different traction machines.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown, a traction roller with a cooling structure includes a traction roller body 1, extension rods 2 are installed at both ends of the traction roller body 1, and a rotating shaft 3 for connecting to a bearing seat is installed on the extension rod 2. A cooling component 4 for a fluid coolant is arranged inside the traction roller body 1, and a water storage tank 5 and a delivery pump 6 for circulating the coolant are connected to both ends of the cooling component 4.

[0024] In this embodiment, the cooling assembly 4 includes a plurality of cooling channels 408 . The cooling channels 408 are respectively opened inside the traction roller body 1 . Extended grooves 409 for increasing the cooling area are respectively opened on both sides of each cooling channel 408 .

[0025] In this embodiment, a discharge groove 410 for discharging coolant is provided on one side of the traction roller body 1, and a cavity 406 for receiving coolant is provided on the other side of the traction roller body 1. A guide slope 407 is provided inside the cavity 406, and a cooling channel 408 is interconnected with the discharge groove 410 and the cavity 406.

[0026] In this embodiment, a connecting hole 7 is formed inside the extension rod 2 , a rotating groove 405 is formed inside the connecting hole 7 , a connecting sleeve 403 is provided inside the rotating groove 405 , and a sealing gasket 404 is provided between the connecting sleeve 403 and the rotating groove 405 .

[0027] In this embodiment, one side of the connecting sleeve 403 is connected to the water inlet pipe 401 , and the other side of the connecting sleeve 403 is connected to the drain pipe 402 .

[0028] The coolant enters the water inlet pipe 401 and is rotatably connected to the connecting sleeve 403 by the rotating groove 405, so that when the traction roller body 1 continues to rotate, the normal inflow and outflow of the coolant will not be affected. When the coolant enters the cavity 406, due to the continuous rotation of the traction roller body 1, the coolant enters the corresponding cooling channel 408 under the guidance of the guide slope 407, so as to cool the traction roller body 1. In order to increase the cooling area, extended grooves 409 are opened on both sides of the cooling channel 408, so that the contact area between the coolant and the heat source can be increased, and the cooling effect is further improved. After cooling, the coolant will be uniformly collected in the discharge groove 410, and finally the coolant after heat exchange will be discharged through the drain pipe 402.

[0029] In this embodiment, a delivery pump 6 is fixedly installed at the water outlet of the water storage tank 5 .

[0030] In this embodiment, the water inlet pipe 401 is connected to the water outlet of the delivery pump 6 , and the water outlet pipe 402 is connected to the water inlet of the water storage tank 5 .

[0031] By starting the delivery pump 6, the coolant stored in the water tank 5 can be pumped out and then transferred to the water inlet pipe 401 to realize the liquid supply operation, so that the coolant enters the cooling component 4 to cool the traction roller body 1, so as to avoid the traction roller body 1 from being overheated and causing influence on the material. After cooling is completed, the coolant will be discharged from the drain pipe 402, and finally, under the guidance of the drain pipe 402, the coolant will flow back to the water tank 5, so as to realize continuous cooling treatment, and further ensure the temperature of the current traction roller body 1. The present application needs to use multiple traction roller bodies 1 when in use, and the multiple traction roller bodies 1 can be connected to the water tank 5 through the drain pipe 402 and the water inlet pipe 401, so that a single water tank 5 can be used for multiple traction roller bodies 1, which is convenient for application in different traction machines.

[0032] The working principle of the traction roller with cooling structure:

[0033] When the traction roller body 1 rotates during use, the delivery pump 6 needs to be started to extract the coolant stored in the water storage tank 5, and then transfer it to the water inlet pipe 401. Then the coolant enters the cavity 406. Since the traction roller body 1 continues to rotate, the coolant enters the corresponding cooling channel 408 under the guidance of the guide slope 407, thereby cooling the traction roller body 1.

[0034] In order to increase the cooling area during cooling, extended grooves 409 are provided on both sides of the cooling channel 408, so that the contact area between the coolant and the heat source can be increased, further improving the cooling effect. After cooling, the coolant will be uniformly collected in the discharge groove 410, and finally discharged through the drain pipe 402 after heat exchange;

[0035] When the coolant is discharged through the drain pipe 402, under the guidance of the drain pipe 402, the coolant can flow back into the water storage tank 5 to achieve circulating cooling.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
