Description

Technical Field

[0001] This application relates to the field of felt replacement equipment, and particularly to a new type of automatic felt replacement device. Background Art

[0002] The function of the automatic felt replacement device in the new type of tension pad device is to prevent scratches on the surface of the strip during the process of clamping the strip by the upper and lower mechanical equipment of the tension pad device to establish tension, which may cause quality defects in the finished product, through the clean felts that are always online and spread on the upper and lower surfaces of the strip by the automatic felt replacement device.

[0003] In the related art, the traditional tension pad device does not have a dedicated felt replacement device. The felt cut into a square shape is manually laid and bound on the equipment that contacts the upper and lower surfaces of the strip in the tension device; the whole process involves manual cutting and regular manual replacement, and the replacement process requires shutting down the machine, removing the old felt, and binding the new felt.

[0004] There are many problems in this way during use: Since the downtime is long, it directly affects the production efficiency; the processes of cutting, replacing, and binding increase the workload of the operator and increase the labor cost. Summary of the Invention

[0005] This application provides a new type of automatic felt replacement device, aiming to optimize the overall process of felt replacement, thereby facilitating the improvement of the felt replacement efficiency and the overall production efficiency. At the same time, it can effectively reduce the workload and labor cost.

[0006] This application provides a new type of automatic felt replacement device, adopting the following technical solutions: A new type of automatic felt replacement device includes upper and lower sets of coiling mechanisms. Each coiling mechanism includes two support plates, both of which are vertically arranged and spaced apart in the horizontal direction. A rotating shaft and a discharge box are arranged between the two support plates. The rotating shaft and the discharge box are both horizontally arranged and are distributed at the left and right ends of the two support plates. The discharge box is hollow inside, and a discharge port for discharging the felt is opened along the length direction of the top of the discharge box. The coiled felt is stored in the discharge box.

[0007] By adopting the above technical solution, after the felt is placed in the discharge box, the roll head of the felt is led to the rotating shaft along the designed path through the discharge port, and the led roll head is flatly fixed on the rotating shaft by means of tape sticking. The felt in the discharge box is gradually taken out by the rotation of the rotating shaft, so as to realize the function of automatic felt replacement. Both sets of coiling mechanisms are fastened to the corresponding mounting brackets by fastening bolts, and the two sets of coiling mechanisms are integrally connected by using the mounting brackets. The two sets of coiling mechanisms can process two sets of felts at the same time, which is beneficial to improving the overall production efficiency of the felt. The structures and working principles of the two sets of coiling mechanisms are the same. In the embodiment of the present application, only one set of coiling mechanisms is taken as an example for illustration.

[0008] This setting method can effectively optimize the overall process of felt replacement, which is beneficial to improving the efficiency of felt replacement and the overall production efficiency. At the same time, it can effectively reduce the workload and labor costs.

[0009] Preferably, a plurality of mounting chucks are fixed on the support plate by fastening bolts. The left and right ends of the rotating shaft and the discharge box are fastened to the support plate by the mounting chucks. A bottom plate is fixed horizontally on one side of the support plate. A driving motor is installed on the top of the bottom plate. The driving motor is fastened to the top of the bottom plate by corresponding fastening bolts. The driving end of the driving motor is integrally connected to the end of the rotating shaft through a corresponding coupling.

[0010] By adopting the above technical solution, the rotating shaft and the discharge box are positioned by the mounting chucks, which can effectively ensure the stability of the rotating shaft and the discharge box during the felt replacement process. The rotating shaft is driven to rotate by the driving motor and the coupling.

[0011] Preferably, the discharge box is composed of an upper box body and a lower box body which are distributed up and down. The mutually close sides of the upper box body and the lower box body are recessed with limiting grooves in the direction away from each other. The felt is stored in the two upper and lower limiting grooves. The sides of the upper box body and the lower box body away from the rotating shaft are hinged, and the sides of the upper box body and the lower box body close to the rotating shaft are opened or closed accordingly.

[0012] By adopting the above technical solution, the upper and lower limiting grooves form a cylindrical groove. The rolled felt is stored in the upper and lower limiting grooves, and the felt is limited by the two limiting grooves, which is beneficial to ensuring the stability of the felt during the unwinding process. The discharge port is opened at the top of the upper box body, and the discharge port is communicated with the two limiting grooves. When the felt in the discharge box is used up and new felt needs to be added, the sides of the upper box body and the lower box body close to the rotating shaft are opened, the new felt is put in, and then the upper box body and the lower box body are closed. At the same time, the roll head of the felt is extended from the discharge port of the upper box body and connected to the rotating shaft by gluing.

[0013] Preferably, one side of the upper box body and the lower box body close to the rotating shaft is connected by magnetic attraction.

[0014] By adopting the above technical solution, the magnetic attraction connection method makes the opening of the upper box body and the lower box body simple and efficient. At the same time, during the closing process of the upper box body and the lower box body, the tightness between the upper box body and the lower box body can be effectively guaranteed, thereby effectively guaranteeing the stability of the felt unwinding process.

[0015] Preferably, a plurality of auxiliary rollers are installed at the discharge port of the upper box body. The plurality of auxiliary rollers are used to assist in unwinding the felt during the felt unwinding process. The plurality of auxiliary rollers are divided into two rows, and the two rows of auxiliary rollers are distributed on the left and right sides of the discharge port. A gap for the felt to pass through is reserved between the two rows of auxiliary rollers. Two rotating shafts are fixed horizontally at the top of the upper box body, and the two rows of auxiliary rollers are rotatably installed on the corresponding rotating shafts.

[0016] By adopting the above technical solution, the plurality of auxiliary rollers assisting in unwinding the felt during the felt unwinding process is beneficial to further strengthen the stability of the felt during the unwinding process, thereby effectively avoiding the deviation of the position of the felt during the unwinding process. Once the position of the felt deviates during the unwinding process, the position of the felt on the rotating shaft will gradually become disordered during winding. When all the felt is wound up, the staff needs to reorganize the position of the felt again, thus increasing the process and reducing the production efficiency. Using the auxiliary rollers to limit the position of the felt in advance during the felt unwinding process is beneficial to avoiding the deviation of the position of the felt during the unwinding process. After the felt is unwound and wound, there is no need to reorganize the position of the felt again, which is beneficial to improving the overall production efficiency of the felt. And while the auxiliary rollers limit the position of the felt during the felt unwinding process, the auxiliary rollers rotate under the drive of the felt, and thus will not affect the normal unwinding speed of the felt.

[0017] Preferably, two storage plates are integrally formed at the discharge port of the upper box body. The two storage plates are respectively located below the two rows of auxiliary rollers. The storage plates are filled with dust-proof agents. The auxiliary rollers are connected to the corresponding storage plates in a seamless manner. When the felt is unwound through the discharge port, while the auxiliary rollers assist in discharging the felt, the dust-proof agents in the corresponding storage plates are smeared on the surface of the felt.

[0018] By adopting the above technical solution, since the surface of the felt is relatively rough, it is extremely easy to adhere to the dust in the air during the production and processing process, which requires additional processes to remove the dust from the felt subsequently, affecting the production efficiency. By using the auxiliary roller and the storage plate, the dust-proof agent can be synchronously applied to the surface of the felt while the felt is unrolled, enabling the unrolling of the felt and the dust-proof process to be carried out simultaneously. Furthermore, there is no need to perform subsequent dust removal on the felt, further simplifying the processes in the production and processing of the felt and facilitating the improvement of its production efficiency.

[0019] Meanwhile, the traditional method of dust-proofing the felt is carried out after the felt is unrolled. This method not only has low efficiency, but also when the felt is contaminated by dust during the unrolling process and then processed subsequently, it is very difficult to completely remove all the dust adhering to the felt, which will affect the quality of the subsequent processing of the felt. In this application, when the felt exits from the discharge box, it can be dust-proofed under the action of the auxiliary roller immediately, which can minimize the dust in the air from falling onto the felt to the greatest extent, thus effectively ensuring the quality of the subsequent processing of the felt.

[0020] Preferably, the storage plate is integrally inclined, with its end away from the auxiliary roller at a higher position and its end close to the auxiliary roller at a lower position, and the end of the storage plate close to the auxiliary roller is bent into a hook shape in the direction towards the auxiliary roller.

[0021] By adopting the above technical solution, the storage plate is inclined, enabling the dust-proof agent filled in the storage plate to gather under the auxiliary roller, which is convenient for the auxiliary roller to apply the dust-proof agent to the surface of the felt. Meanwhile, the end of the storage plate close to the auxiliary roller is bent into a hook shape in the direction towards the auxiliary roller, which can effectively prevent the dust-proof agent from slipping off the storage plate, thus realizing the storage of the dust-proof agent on the storage plate.

[0022] Preferably, the auxiliary roller is provided with arc-shaped aggregate grooves at equal intervals along its circumferential side.

[0023] By adopting the above technical solution, when the auxiliary roller rotates onto the storage plate, the aggregate grooves can smoothly concentrate the dust-proof agent on the storage plate in the aggregate grooves temporarily. When the auxiliary roller rotates to the position of the felt, the dust-proof agent in the aggregate grooves is then applied to the surface of the felt. The aggregate grooves can enable the dust-proof agent to be stably stored on the circumferential side of the auxiliary roller. The dust-proof agent falls into the aggregate grooves and will not easily fall off the auxiliary roller. When the auxiliary roller rotates into contact with the felt, since the surface of the felt is rough and uneven, the dust-proof agent in the aggregate grooves can easily adhere to the felt when passing by the felt, thus achieving the effect of dust-proofing.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. After the felt is placed in the discharge box, the end of the felt roll is led to the rotating shaft along the designed path through the discharge port, and the led end of the roll is flatly fixed on the rotating shaft by means of tape sticking. The felt in the discharge box is gradually taken out by the rotation of the rotating shaft, thus realizing the function of automatic felt replacement. Both sets of coiling mechanisms are fastened to the corresponding mounting brackets by fastening bolts, and the two sets of coiling mechanisms are integrally connected by the mounting brackets. The two sets of coiling mechanisms can process two sets of felts simultaneously, which is conducive to improving the overall production efficiency of the felt. The structures and working principles of the two sets of coiling mechanisms are the same. In the embodiment of the present application, only one set of coiling mechanism is taken as an example for illustration.

[0025] This setting method can effectively optimize the overall process of felt replacement, which is conducive to improving the efficiency of felt replacement and the overall production efficiency. At the same time, it can effectively reduce the workload and labor costs. 2. Multiple auxiliary rollers assist in unwinding the felt during the unwinding process of the felt, which is conducive to further enhancing the stability of the felt during the unwinding process. Thus, it can effectively prevent the position of the felt from deviating during the unwinding process. Once the position of the felt deviates during the unwinding process, the position of the felt on the rotating shaft will gradually become disordered during winding. After the felt is completely wound, the staff needs to re-organize the position of the felt, which increases the process and reduces the production efficiency. Using the auxiliary rollers to limit the position of the felt in advance during the unwinding process is conducive to preventing the position of the felt from deviating during the unwinding process. After the felt is unwound and wound, there is no need to re-organize the position of the felt, which is conducive to improving the overall production efficiency of the felt. Moreover, while the auxiliary rollers limit the position of the felt during the unwinding process of the felt, the auxiliary rollers rotate under the drive of the felt, and thus do not affect the normal unwinding speed of the felt. 3. Since the surface of the felt is relatively rough, it is extremely easy to adhere to the dust in the air during the production and processing process, which makes it necessary to add subsequent processes for removing dust from the felt, affecting the production efficiency. By using the auxiliary rollers and the storage plate, the dust-proof agent can be synchronously applied to the surface of the felt while the felt is unwound, so that the unwinding of the felt and dust prevention are carried out simultaneously. Thus, there is no need to perform subsequent dust removal treatment on the felt, further simplifying the process in the felt processing and production process, which is conducive to improving its production efficiency.

[0026] Meanwhile, the traditional felt dust prevention is carried out after the felt unrolling is completed. This method not only has low efficiency, but also because the felt is contaminated by dust during the unrolling process and it is very difficult to completely clean all the dust sticking to the felt during subsequent processing, which will affect the quality of the subsequent processing of the felt. In this application, when the felt is discharged from the discharge box, dust prevention can be carried out immediately under the action of the auxiliary rollers, which can minimize the dust in the air from falling on the felt, thereby effectively ensuring the quality of the subsequent processing of the felt.

Detailed Description of the Embodiment

[0029] The following will Figure 1 - be Figure 4 further described in detail with reference to the attached

[0030] Embodiment: The embodiment of this application discloses a new type of automatic felt changing device, including two sets of winding mechanisms, upper and lower. Both sets of winding mechanisms are fastened to the corresponding mounting brackets through fastening bolts, and the two sets of windings are integrally connected by the mounting brackets. Through the two sets of winding mechanisms, two sets of felts can be processed simultaneously, which is beneficial to improving the overall production efficiency of the felts. The structures and working principles of the two sets of winding mechanisms are the same. In the embodiment of this application, only one set of winding mechanism is taken as an example for description.

[0031] Specifically, refer to Figure 1, The coiling mechanism includes two support plates 1, both of which are vertically arranged and spaced apart in the horizontal direction. A rotating shaft 2 and a discharge box 3 are provided between the two support plates 1. The rotating shaft 2 and the discharge box 3 are both horizontally arranged and are located at the left and right ends of the two support plates 1 respectively. The inside of the discharge box 3 is hollow, and a discharge port 4 for discharging the felt is opened at the top of the discharge box 3 along its length direction. The coiled felt is stored in the discharge box 3. After the felt is placed in the discharge box 3, the end of the felt roll is led to the rotating shaft 2 along the designed path through the discharge port 4, and the led end of the roll is fixed flatly on the rotating shaft 2 by means of tape sticking. The felt in the discharge box 3 is gradually taken out by the rotation of the rotating shaft 2, so as to realize the function of automatic felt replacement.

[0032] This setting method can effectively optimize the overall process of felt replacement, which is beneficial to improving the efficiency of felt replacement and the overall production efficiency. At the same time, it can effectively reduce the workload and labor costs.

[0033] Specifically, referring to Figure 1 , a plurality of mounting chucks 5 are fixed on the support plate 1 by fastening bolts. The left and right ends of the rotating shaft 2 and the discharge box 3 are fastened to the support plate 1 by the mounting chucks 5. The mounting chucks 5 are used to position the rotating shaft 2 and the discharge box 3, which can effectively ensure the stability of the rotating shaft 2 and the discharge box 3 during the felt replacement process.

[0034] Referring to Figure 1 , a bottom plate 6 is welded horizontally on one side of the support plate 1. The bottom plate 6 is in the shape of a cuboid. A driving motor 7 is installed on the top of the bottom plate 6. The driving motor 7 is fastened to the top of the bottom plate 6 by corresponding fastening bolts. The driving end of the driving motor 7 is integrally connected to the end of the rotating shaft 2 through a corresponding coupling, and then the rotating shaft 2 is driven to rotate by the driving motor 7 and the coupling.

[0035] Specifically, referring to Figure 1 and Figure 2 , the discharge box 3 is composed of an upper box body 8 and a lower box body 9 which are distributed up and down. Both the upper box body 8 and the lower box body 9 are in the shape of a cuboid. The sides of the upper box body 8 and the lower box body 9 close to each other are recessed with limiting grooves 10 in the direction away from each other. Specifically, during operation, the felt is stored in the upper and lower limiting grooves 10. The upper and lower limiting grooves 10 form a cylindrical groove. The coiled felt is stored in the upper and lower limiting grooves 10, and the felt is limited by the two limiting grooves 10, which is beneficial to ensuring the stability of the felt during the uncoiling process. The discharge port 4 is opened at the top of the upper box body 8, and the discharge port 4 is in communication with the two limiting grooves 10.

[0036] The side of the upper box body 8 and the lower box body 9 away from the rotating shaft 2 is hinged, and the side of the upper box body 8 and the lower box body 9 close to the rotating shaft 2 is opened or closed accordingly. When the felt in the discharging box 3 is used up and new felt needs to be added, the side of the upper box body 8 and the lower box body 9 close to the rotating shaft 2 is opened, and after putting the new felt in, the upper box body 8 and the lower box body 9 are closed. At the same time, the roll head of the felt extends out from the discharging port 4 of the upper box body 8 and is connected to the rotating shaft 2 by gluing.

[0037] Specifically, the side of the upper box body 8 and the lower box body 9 close to the rotating shaft 2 is connected by magnetic attraction. This connection method makes the opening of the upper box body 8 and the lower box body 9 simple and efficient. At the same time, during the closing process of the upper box body 8 and the lower box body 9, the tightness of the closure between the upper box body 8 and the lower box body 9 can be effectively guaranteed, thereby effectively guaranteeing the stability of the felt unwinding process.

[0038] Further, referring to Figure 1 , a plurality of auxiliary rollers 11 are installed at the discharging port 4 of the upper box body 8. The felt contacts the auxiliary rollers 11 when unwinding through the discharging port 4. These auxiliary rollers 11 assist the felt during the unwinding process of the felt, which is beneficial to further strengthening the stability of the felt during the unwinding process. Furthermore, it can effectively prevent the position of the felt from deviating during the unwinding process. Once the position of the felt deviates during the unwinding process, the position of the felt on the rotating shaft 2 will gradually become disordered during winding. When all the felt is wound up, the staff needs to reorganize the position of the felt again, which increases the process and reduces the production efficiency. Using the auxiliary rollers 11 to limit the position of the felt in advance during the unwinding process is beneficial to preventing the position of the felt from deviating during the unwinding process. After the winding and unwinding of the felt are completed, there is no need to reorganize the position of the felt again, which is beneficial to improving the overall production efficiency of the felt. And while the auxiliary rollers 11 limit the position of the felt during the unwinding process of the felt, the auxiliary rollers 11 rotate under the drive of the felt, and thus do not affect the normal unwinding speed of the felt.

[0039] Specifically, these auxiliary rollers 11 are divided into two rows. The two rows of auxiliary rollers 11 are distributed on the left and right sides of the discharging port 4, and a gap for the felt to pass through is reserved between the two rows of auxiliary rollers 11. Two rotating shafts are fixed horizontally on the top of the upper box body 8, and the two rows of auxiliary rollers 11 are rotatably installed on the corresponding rotating shafts.

[0040] Further, referring to Figure 1 and Figure 3, two storage plates 12 are integrally formed at the discharge port 4 of the upper box body 8, and the two storage plates 12 are respectively located below the two rows of auxiliary rollers 11. The storage plates 12 are filled with dustproof agents, and the auxiliary rollers 11 and the corresponding storage plates 12 are connected and connected. When the felt is unrolled through the discharge port 4, the auxiliary rollers 11 assist in the discharge of the felt and apply the dustproof agent in the corresponding storage plate 12 to the surface of the felt, thereby enhancing the dustproof ability of the felt through the dustproof agent. Since the surface of the felt is relatively rough, it is very easy to be stained with dust in the air during the production and processing process, so that it is necessary to add a process of removing dust from the felt in the subsequent process, which affects the production efficiency. In the embodiment of the present application, the auxiliary rollers 11 and the storage plates 12 are used, and the dustproof agent can be synchronously applied to the surface of the felt while the felt is unrolled, so that the unrolling and dust prevention of the felt are carried out simultaneously, and there is no need to perform dust removal on the felt in the subsequent process, which further simplifies the process in the felt processing and production process, which is conducive to improving its production efficiency.

[0041] Meanwhile, the traditional dust prevention of felt is carried out after the felt is unrolled, which is not only inefficient, but also difficult to remove all the dust on the felt when it is subsequently processed because the felt is contaminated by dust during the unrolling process, which will affect the quality of the subsequent processing of the felt. In the present application, when the felt is discharged from the discharge box 3, it can be dust-proofed at the first time under the action of the auxiliary roller 11, thereby minimizing the dust in the air from falling on the felt, thereby effectively ensuring the quality of the subsequent processing of the felt.

[0042] Specifically, the material storage plate 12 is tilted as a whole, with the end away from the auxiliary roller 11 being at a high position, and the end close to the auxiliary roller 11 being at a low position, and the end of the material storage plate 12 close to the auxiliary roller 11 being bent into a hook shape in the direction close to the auxiliary roller 11. The material storage plate 12 is tilted so that the dust-proofing agent filled in the material storage plate 12 can be collected under the auxiliary roller 11, thereby facilitating the auxiliary roller 11 to apply the dust-proofing agent to the surface of the felt. At the same time, the end of the material storage plate 12 close to the auxiliary roller 11 is bent into a hook shape in the direction close to the auxiliary roller 11, which can effectively prevent the dust-proofing agent from sliding off the material storage plate 12, thereby realizing the storage of the dust-proofing agent on the material storage plate 12.

[0043] Further, refer to Figure 1 , Figure 3 as well as Figure 4, the auxiliary roller 11 is evenly provided with arc-shaped material collecting grooves 13 at intervals along its circumferential side. When the auxiliary roller 11 rotates onto the storage plate 12, the dust-proof agent on the storage plate 12 can be smoothly concentrated in the material collecting grooves 13 by using the material collecting grooves 13. When the auxiliary roller 11 rotates to the felt, the dust-proof agent in the material collecting grooves 13 is then applied to the surface of the felt. By using the material collecting grooves 13, the dust-proof agent can be stably stored on the circumferential side of the auxiliary roller 11. The dust-proof agent falls into the material collecting grooves 13 and will not easily fall off the auxiliary roller 11. When the auxiliary roller 11 rotates into contact with the felt, since the surface of the felt is rough and uneven, the dust-proof agent in the material collecting grooves 13 can easily adhere to the felt when passing through the felt, thereby achieving the effect of dust prevention.

[0044] In this embodiment, the depth of the material collecting grooves 13 is not very deep but relatively shallow. The purpose of doing this is to be able to smoothly hang the dust-proof agent in the material collecting grooves 13 on the surface of the felt. If the material collecting grooves 13 are too deep, the dust-proof agent will fall to the bottom of the material collecting grooves 13, which will in turn affect the effect of applying the dust-proof agent to the surface of the felt. The specific depth of the material collecting grooves 13 is subject to corresponding test detections before specific processing. After multiple tests and summaries, the most appropriate depth is selected for processing.

[0045] The implementation principle of a new type of automatic felt changing device in the embodiment of the present application is as follows: Specifically, the coiling mechanism includes two support plates 1. Both support plates 1 are vertically arranged and are spaced apart in the horizontal direction. A rotating shaft 2 and a discharge box 3 are provided between the two support plates 1. The rotating shaft 2 and the discharge box 3 are both horizontally arranged and are distributed at the left and right ends of the two support plates 1. The inside of the discharge box 3 is hollow. A discharge port 4 for discharging the felt is opened at the top of the discharge box 3 along its length direction. The coiled felt is stored in the discharge box 3. After the felt is placed in the discharge box 3, the end of the felt roll is led to the rotating shaft 2 along the designed path through the discharge port 4, and the led end of the roll is flatly fixed on the rotating shaft 2 by means of tape sticking. By the rotation of the rotating shaft 2, the felt in the discharge box 3 is gradually taken out, thereby realizing the function of automatically changing the felt.

[0046] This setting method can effectively optimize the overall process of felt replacement, which is beneficial to improving the efficiency of felt replacement and the overall production efficiency. At the same time, it can effectively reduce the workload and reduce the labor cost.

[0047] By using the auxiliary roller 11 to limit the position of the felt in advance during the felt unwinding process, it is beneficial to avoid the deviation of the position of the felt during the unwinding process. After the felt is wound and unwound, there is no need to re-arrange the position of the felt, which is beneficial to improving the overall production efficiency of the felt. And while the auxiliary roller 11 limits the position of the felt during the felt unwinding process, the auxiliary roller 11 rotates under the drive of the felt, and thus does not affect the normal unwinding speed of the felt.

[0048] The aggregate chute 13 can smoothly concentrate the dust-proof agent on the storage plate 12 in the aggregate chute 13 temporarily. When the auxiliary roller 11 rotates to the felt, the dust-proof agent in the aggregate chute 13 is then applied to the surface of the felt. The use of the aggregate chute 13 enables the dust-proof agent to be stably stored on the periphery of the auxiliary roller 11. The dust-proof agent falls into the aggregate chute 13 and will not easily fall off the auxiliary roller 11. When the auxiliary roller 11 rotates into contact with the felt, since the surface of the felt is rough and uneven, the dust-proof agent in the aggregate chute 13 can easily adhere to the felt when passing by the felt, thus achieving the dust-proof effect.

[0049] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
