[0053] The following will be combined with the drawings in 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0054] See also Figure 1-7 The utility model discloses a roller cleaning device, comprising:

[0055] Roller 01;

[0056] A cleaning scraper 1 in contact with the roller 01, the cleaning scraper 1 is used to scrape dirt off the surface of the roller. It should be noted that the cleaning scraper 1 can be arranged obliquely along the rotation direction of the roller 01 to avoid the scraped dirt from accumulating at the connection between the roller 01 and the cleaning scraper 1;

[0057] A support frame 2 for carrying the cleaning scraper 1, wherein the support frame 2 is arranged at one end of the cleaning scraper 1;

[0058] A sliding scraper 3 is arranged on the surface of the cleaning scraper 1, and the sliding scraper 3 is used to move horizontally to remove the dirt accumulated and on the surface of the cleaning scraper 1;

[0059] The end of the cleaning scraper 1 away from the roller 01 is provided with a transmission part 11, and a reciprocating screw 5 is rotatably provided in the transmission part 11, and a slide groove is provided on the reciprocating screw 5. It should be noted that the slide groove on the reciprocating screw 5 is a thread with opposite ends and interlaced with each other. The reciprocating screw 5 is a common technical means in the prior art, so its specific parameters and structure are not described in detail;

[0060] The sliding scraper 3 includes a sliding column 31 adapted to the slide groove, a limit seat 32 and an inclined swing arm 33 fitted with the sliding scraper 3. The reciprocating screw 5 rotates to drive the sliding scraper 3 to reciprocate along the surface of the cleaning scraper 1 through the sliding column 31 to clean the surface of the cleaning scraper 1.

[0061] When the present application is in use, the dirt and impurities on the surface of the leather roller 01 are cleaned off by the cleaning scraper 1. In order to clean the dirt accumulated on the cleaning scraper 1 and prevent it from accumulating at the connection between the cleaning scraper 1 and the leather roller 01 to affect the subsequent cleaning effect, a sliding scraper 3 that is in contact with the cleaning scraper 1 is proposed. The sliding scraper 3 is transmission-connected to the reciprocating screw 5. When the reciprocating screw 5 rotates, it can drive the sliding scraper 3 to reciprocate on the cleaning scraper 1, thereby cleaning the dirt on the cleaning scraper 1.

[0062] It should be noted that, in order to make the sliding scraper 3 tilted on the cleaning scraper 1 and better guide the dirt to the side away from the roller 01, the limiting seat 32 is provided with a traction spring 34 and a limiting arc groove 35, the limiting seat 32 is rotatably connected with the tilting swing arm 33, and the tilting swing arm 33 is provided with a traction shaft 36 fixedly connected with the traction spring 34 and penetrating the limiting arc groove 35;

[0063] The traction spring 34 is used to pull the traction shaft 36 to deflect the traction shaft 36 to one side of the limiting arc groove 35 , so that the tilting swing arm 33 is tilted and fits the surface of the sliding scraper 3 .

[0064] Furthermore, movable abutment rods 4 are provided on both sides of the cleaning scraper 1, and the movable abutment rods 4 are used to contact the tilting swing arm 33, scrape off the dirt accumulated on the tilting swing arm 33, and push the tilting swing arm 33 to tilt to the other side.

[0065] Through the above-mentioned structural setting, when the sliding scraper 3 slides, the sliding scraper 3 can be deflected to the other side by the resistance of the movable resistance rod 4 when it moves to one side of the cleaning scraper 1. During the deflection of the sliding scraper 3, the traction spring 34 can pull the tilting swing arm 33 and the traction shaft 36 to deflect to the other side, and make the traction shaft 36 clamped to the other end of the limiting arc groove 35.

[0066] It should be noted that the tilting direction of the tilting swing arm 33 is consistent with its moving direction, and the pulling force of the traction spring 34 is greater than the friction between the tilting swing arm 33 and the cleaning scraper 1, which prevents the tilting swing arm 33 from swinging when the cleaning scraper 1 moves, thereby failing to collect dirt.

[0067] It is further necessary to add that the movable resisting rod 4 includes a sliding groove 44 opened on both sides of the sliding scraper 3, a limiting rod 41 is arranged in the sliding groove 44, a moving block 42 is sleeved on the limiting rod 41, a contact scraper rod 45 extending to the front of the sliding scraper 3 is arranged on the moving block 42, and a return spring 43 that contacts the moving block 42 is also sleeved on the limiting rod 41;

[0068] The return spring 43 is used to keep the contact scraper rod 45 on the top of the tilting swing arm 33 until it contacts it and performs comprehensive scraping.

[0069] In the above structure, the movable stop rod 4 is used not only to change the rotation direction of the tilting swing arm 33, but also to separate the dirt cleaned from the tilting swing arm 33 and facilitate collection.

[0070] Specifically, through the setting of the return spring 43, the return spring 43 contacts the moving block 42, and the moving block 42 is fixedly connected to the contact scraper rod 45. When the tilting swing arm 33 contacts the contact scraper rod 45 for the first time, since the tilting swing arm 33 is in a tilted state, it can press the contact scraper rod 45 downward when it continues to move, so that the contact scraper rod 45 moves downward relatively along the tilting swing arm 33, thereby achieving the purpose of cleaning the dirt on the tilting swing arm 33, until the moving block 42 moves to the lowest point, the tilting swing arm 33 continues to translate. At this time, the contact scraper rod 45 is relatively fixed by the resistance, and the tilting swing arm 33 is deflected under the action of the traction spring 34. After the tilting swing arm 33 is deflected, it is separated from the contact scraper rod 45. At this time, the contact scraper rod 45 is reset and raised under the action of the return spring 43, waiting for the next contact with the tilting swing arm 33, and the above process is repeated under the action of the reciprocating screw rod 5, thereby achieving the purpose of efficient cleaning and preventing dirt accumulation.

[0071] In the present application, it is easy to imagine that a connecting groove is provided on the transmission part 11 of the cleaning scraper 1, and the sliding scraper 3 extends into the transmission part 11 through the connecting groove and is connected to the reciprocating screw 5, and mutually meshing limiting ribs 322 and limiting grooves 321 are provided in the connecting groove and on the limiting seat 32.

[0072] Furthermore, a transmission assembly 6 is arranged between the leather roller 01 and the reciprocating screw rod 5, and the transmission assembly 6 includes a pulley 61 arranged on the leather roller 01, and also includes a driven wheel 62 connected to the reciprocating screw rod 5. The driven wheel 62 is connected to the pulley 61 through a transmission belt transmission, so that the reciprocating screw rod 5 can run synchronously with the rotation of the leather roller 01. It should be noted that the diameter of the driven wheel 62 is larger than the diameter of the pulley 61. Under the drive of the transmission assembly 6, the cleaning scraper 1 and the leather roller 01 have the same rotation direction. When the cleaning scraper 1 rotates, it can approach the leather roller 01 until it is in contact with it.

[0073] It is easy to imagine that the leather roller 01 is arranged on a mounting seat 8, and a plurality of collecting boxes 81 located below the movable support rod 4 are provided on the mounting seat 8 to collect fallen dirt. In the present application, a transmission structure corresponding to the leather roller 01 should also be provided to provide power to the leather roller so that it can rotate for easy cleaning or to realize the transportation of yarn.

[0074] like Figure 4As shown, the width of the transmission part 11 is greater than the length of the cleaning scraper 1, and the length of the reciprocating screw 5 is also greater than the length of the cleaning scraper 1. At the same time, the length of the cleaning scraper 1 is also greater than the length of the leather roller 01, which is convenient for comprehensive cleaning of dirt on the leather roller 01;

[0075] The transmission part 11 is rotationally connected to the support frame 2, and a connecting hole is opened on the side of the transmission part 11 away from the support frame 2, and the connecting hole is for the reciprocating screw 5 to be placed inside the transmission part 11. That is to say, one side of the cleaning scraper 1 is fixed by the support frame 2, and the reciprocating screw 5 rotates synchronously with the leather roller 01, and the reciprocating screw 5 extends from the other side of the cleaning scraper 1 to its interior, driving the sliding scraper 3 for cleaning.

[0076] In this application, another embodiment that needs to be explained is, please refer to Figure 4 , 8 -12, the driven wheel 62 is provided with a power allocation component 7, and the power allocation component 7 is used to drive the cleaning scraper 1 to contact the roller 01 or to drive the reciprocating screw 5 to rotate;

[0077] The power allocation assembly 7 includes a connecting plate 75, a telescopic plate 71 disposed in the connecting plate 75, a trigger push rod 72, a telescopic column 73 and a resisting spring 74;

[0078] The telescopic disc 71 is provided with a movably connected chuck 711, and a connecting pin 712 penetrating the connecting chuck 711 is provided at the center of the telescopic disc 71. The reciprocating screw rod 5 is provided with a transmission pin hole corresponding to the connecting pin 712.

[0079] The telescopic disc 71 is provided with a rotation groove corresponding to the connecting chuck 711, and a reset torsion spring 7111 fixedly connected to the connecting chuck 711 is arranged in the rotation groove. A limit rotation groove 7112 corresponding to the connecting chuck 711 is also provided on the side wall of the rotation groove. It should be noted that the elastic force required for the twisting of the reset torsion spring 7111 is greater than the gravity of the cleaning scraper 1, wherein the limit rotation groove 7112 is provided so that the connecting chuck 711 can be rotated and at the same time, the telescopic disc 71 can be retracted by being pushed by the trigger push rod 72;

[0080] The trigger push rod 72 is arranged in the connecting chute, and a trigger is provided at one end of the trigger push rod 72 located inside the connecting chute. The trigger is used to contact the limit seat 32, drive the trigger push rod 72 to run through its output end to engage with the connecting chuck 711 on the telescopic disk 71, and push the telescopic disk 71 to contract, so that the connecting chuck pin 712 is disengaged from the reciprocating screw rod 5, so as to drive the cleaning scraper 1 to run and contact the leather roller 01;

[0081] A control unit and a timing unit are also provided in the trigger push rod 72 , and the control unit is used to regularly drive the trigger push rod 72 to retract.

[0082] It should be further supplemented that a limiting support rod (not shown in the figure) for supporting the cleaning scraper 1 is provided on the support frame 2, which is used to support the cleaning scraper 1 and prevent it from tilting excessively when the cleaning scraper 1 tilts downward and rotates without being subjected to force.

[0083] Through the above structure setting, the following steps are included when using:

[0084] In the initial state, the limit seat 32 and the tilting swing arm 33 are located at one end close to the power allocation component 7, and the telescopic disc 71 is in an extended state at this time. The connecting pin 712 provided on the telescopic disc 71 is inserted into the reciprocating screw 5, and the power of the driven wheel 62 is transmitted to the reciprocating screw 5. The reciprocating screw 5 drives the limit seat 32 and the tilting swing arm 33 to perform a reciprocating movement on the cleaning scraper 1. Finally, the limit seat 32 returns to its original position and contacts the trigger provided on the trigger push rod 72.

[0085] When the trigger on the trigger push rod 72 is triggered, the control unit and the timing unit are started, and the control unit controls the output end of the trigger push rod 72 to extend and push the telescopic disk 71 to retract, so that the connecting pin 712 is disengaged from the reciprocating screw 5. At the same time, the output end of the trigger push rod 72 is inserted into the connecting chuck 711. At this time, the power of the driven wheel 62 is transmitted to the cleaning scraper 1, and the reciprocating screw 5 loses power and stops rotating. After the cleaning scraper 1 obtains power, the elastic force required for the twisting of the reset torsion spring 7111 is greater than the gravity of the cleaning scraper 1. , which will drive the cleaning scraper 1 to get close to the leather roller 01 and keep in contact with the leather roller 01. During the contact process, since the cleaning scraper 1 will be limited by the leather roller 01, the continuous output of the driven wheel 62 will drive the reset torsion spring 7111 to rotate, and avoid the driven wheel 62 from slipping with the transmission belt due to the limitation of the cleaning scraper 1 and the leather roller 01, thereby ensuring that the cleaning scraper 1 can keep in contact with the leather roller 01 during the period when the trigger push rod 72 connects the cleaning scraper 1 and the telescopic disk 71, and does not hinder the normal output of the driven wheel 62.

[0086] After the cleaning scraper 1 is in contact with the roller 01 for a period of time, the push rod 72 is triggered to retract under the control of the timing unit and the control unit. At this time, the telescopic disc 71 is extended again under the push of the resistance spring 74, and the cleaning scraper 1 is disengaged from the driven wheel 62, while the reciprocating screw rod 5 is re-engaged with the driven wheel 62 and receives the power of the driven wheel 62;

[0087] By repeating the above steps, it can be ensured that while the cleaning scraper 1 and the leather roller 01 are in continuous contact under the drive of the driven wheel 62, the inclined swing arm 33 set on the cleaning scraper 1 stops running, so as to prevent the operation of the inclined swing arm 33 from affecting the scraping of the surface of the leather roller 01 by the cleaning scraper 1. After the cleaning scraper 1 has been in contact with the leather roller 01 for a period of time, the cleaning scraper 1 rotates and separates from the leather roller 01. At this time, the reciprocating screw 5 and the driven wheel 62 drive the inclined swing arm 33 to perform a reciprocating movement on the cleaning scraper 1 to clean the dirt accumulated on the cleaning scraper 1, thereby effectively improving the cleaning efficiency.

[0088] In the present application, it should be supplemented that the telescopic column 73 and the resistance spring 74 are arranged inside the connecting disk 75. The resistance spring 74 is used to push the telescopic disk 71 and the connecting pin 712 arranged thereon to re-engage with the reciprocating screw 5 and drive the reciprocating screw 5 to operate when the trigger push rod 72 retracts.

[0089] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).
