[0054] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0055] The present embodiment relates to a papermaking net cleaning device, which includes a bracket 2 for supporting a fixing frame 8 of a papermaking net 1, a driving mechanism 3 arranged on the bracket 2, a transmission mechanism 4 driven by the driving mechanism 3 to transmit around the outer side of the papermaking net 1, and a spraying mechanism 5 arranged on the transmission mechanism 4. The spraying mechanism 5 includes at least one spraying part uniformly arranged on the transmission mechanism 4 along the transmission direction, and a plurality of spraying heads 501 arranged at intervals are arranged on the spraying part along the width direction of the papermaking net 1.

[0056] In addition, the spraying part is also provided with a first driving part 502 and a connecting rod mechanism 6 connecting each spraying head 501. The first driving part 502 drives the connecting rod mechanism 6 to swing along the width direction of the papermaking net 1, and the connecting rod mechanism 6 drives each spraying head 501 to swing along the width direction of the papermaking net 1. The transmission mechanism 4 also includes a connecting seat 401 connected to the spraying mechanism 5. The connecting seat 401 includes a fixed part 4011 and a movable part 4012 that are pivotally connected. The spraying head 501 is connected to the movable part 4012, and the fixed part 4011 is connected to the transmission mechanism 4. The fixed part 4011 is also provided with a second driving part 4013 for driving the movable part 4012 to pivot. The second driving part 4013 drives the movable part 4012 to pivot so that the spraying head 501 swings along the length direction of the papermaking net 1.

[0057] The papermaking net cleaning device of this embodiment drives the spraying mechanism 5 connected to the outside of the papermaking net 1 to drive and operate through the driving mechanism 3. When the spraying head 501 is located at the upper part of the papermaking net 1, the second driving part 4013 can drive the spraying head 501 to vertically clean the papermaking net 1, which can increase the pressure of washing the oil stains downward. When the spraying head 501 is located at the lower part of the papermaking net 1, the spraying head 501 can be adjusted to be inclined with the papermaking net 1 to avoid the oil stains being washed back to the upper part by the upper washing liquid. It can also increase the friction of the water flow on the papermaking net 1, which is conducive to the oil stains being washed away from the papermaking net 1 from the bottom. The first driving part 502 is used to adjust the swing of the spraying head 501 along the width direction of the papermaking net 1, which can effectively clean the dead corners and improve the cleaning effect of the papermaking net 1. The structure is simple and the production cost is low.

[0058] Based on the above overall introduction, an exemplary structure of the papermaking mesh cleaning device of this embodiment is as follows: Figures 1 to 3 As shown, the bracket 2 of this embodiment is a rectangular frame structure, and the papermaking mesh cleaning device can be installed on a running vehicle or fixed on the side of the papermaking production line. When inspecting or cleaning the papermaking mesh 1, the papermaking mesh 1 and the papermaking mesh 1 fixing frame 8 are transported to the papermaking mesh cleaning device manually or mechanically.

[0059] like Figure 1 and Figure 2 As shown, the fixed frame 8 of the papermaking net 1 is clamped on the bracket 2 through the groove 201 and the support plate described below, and can be further fixed by bolts or a tightening cylinder or a rotatable pressing plate connected to the bracket 2 after the fixed frame 8 is fixed in place.

[0060] Preferably, if Figure 1 and Figure 2As shown, the driving mechanism 3 includes a driving shaft 301 and a driven shaft 302 pivotally connected to the bracket 2 along the width direction of the papermaking net 1, and a third driving part 303 for driving the driving shaft 301 to rotate. The transmission mechanism 4 includes a driving wheel 402 sleeved on the driving shaft 301 and the driven shaft 302, and a driving chain 403 meshing and transmitting on the outside of the driving wheel 402. The two driving chains 403 are respectively arranged on the two side ends of the fixed frame 8 of the papermaking net 1, and the third driving part 303 is fixedly connected to the bracket 2.

[0061] As Figure 1 and Figure 2 As shown, the papermaking net 1 is located in the middle of the bracket 2. In this embodiment, a driving shaft 301 and three driven shafts 302 are arranged outside the papermaking net 1. Two driving wheels 402 are connected to both sides of the driving shaft 301 and the driven shaft 302, respectively. Two driving chains 403 are connected to the driving wheels 402 fixed on both sides of the papermaking net 1. The driving wheels 402 of this embodiment can be sprockets or pulleys, and the driving chains 403 can be chains or belts. Adaptive adjustments can be made according to the size of the equipment and the number of spray heads 501, which are not limited here.

[0062] The driving shaft 301 and the driven shaft 302 are both fixed to the bracket 2 through the bearing seat 503 or the deep groove ball bearing, and the positions of the driving shaft 301 and the driven shaft 302 are adjusted according to the spraying range. In this embodiment, by setting the driving shaft 301 and the driven shaft 302, and the third driving part 303, it is convenient for the third driving part 303 to drive the driving shaft 301 to rotate, thereby driving the driving wheel 402 and the driving chain 403 to transmit. The structure is simple to set, the components are standard parts, easy to purchase and implement, and the cost investment is low.

[0063] Furthermore, if Figure 5 As shown, a hinge 4014 is provided between the movable part 4012 and the fixed part 4011, the fixed end of the second driving part 4013 is hingedly connected to the fixed part 4011, and the transmission mechanism 4 also includes a connecting plate 405 connected to one side of each movable part 4012; the power output end of the second driving part 4013 is hingedly connected to the connecting plate 405. The second driving part 4013 of this embodiment adopts a telescopic cylinder, and round pins 306 are provided at both ends of the second driving part 4013. A connecting seat 401 is provided on the fixed part 4011 to connect with the second driving part 4013. In this embodiment, by providing a hinge 4014 between the movable part 4012 and the fixed part 4011, the flexibility of the movable part 4012 driving the sprinkler head 501 to swing is increased.

[0064] In addition, combined Figure 1 and Figure 4As shown, a fixing plate 404 is provided between the fixing part 4011 and the driving chain 403, and the fixing plate 404 is connected to the two driving chains 403 along the width direction of the papermaking net 1, and the first driving part 502 is arranged in the middle of the fixing plate 404. The power output end of the first driving part 502 is connected to the rocker arm 304, and the rocker arm 304 is hingedly connected to the connecting rod mechanism 6. The fixing plate 404 of this embodiment adopts a planar plate structure, and is fixedly connected to the two driving chains 403 by bolts or rivets.

[0065] like Figure 4 As shown, the first driving part 502 adopts a driving motor, and a rocker arm 304 is sleeved on the power output shaft of the driving motor. The rocker arm 304 in this embodiment is a strip plate structure, and the other end of the rocker arm 304 is connected to the long rod 305 described below. By setting the first driving part 502 to drive the rocker arm 304 to rotate, the spray head 501 is driven to swing along the width direction of the papermaking net 1 through the connecting rod mechanism 6, and the rotation of the rocker arm 304 causes the connecting rod to swing back and forth, thereby improving the cleaning effect and cleaning efficiency.

[0066] Specifically, Figure 3 As shown, the connecting rod mechanism 6 includes a plurality of connecting rods 601 connecting a plurality of spray heads 501, and a long rod 305 hingedly connected to the connecting rods 601, and the long rod 305 is hingedly connected to the rocker arm 304. The connecting rod 601 is extended along the length direction of the fixed plate 404. When the rocker arm 304 is driven to rotate, the long rod 305 reciprocates with the rocker arm 304. In order to prevent the spray head 501 from shaking up and down seriously, the length of the long rod 305 is much greater than the rocker arm 304.

[0067] In addition, it should be pointed out that if Figure 3 and Figure 4 As shown, a universal joint bearing 307 is provided at the connection between the long rod 305 and the connecting rod 601. When the second driving part 4013 drives the movable part 4012 to rotate, the connecting rod 601 can rotate a certain angle with the spray head 501 to prevent the connecting rod 601 and the long rod 305 from getting stuck.

[0068] As a preferred implementation mode, Figure 3 As shown, the connecting rod 601 of this embodiment includes a plurality of short rods connected to two adjacent spray heads 501, and the two short rods are hingedly connected. By configuring the connecting rod 601 as a plurality of short rods connected by hinges, the connecting rod 601 can be more flexible when swinging, avoiding jamming and affecting the spraying effect.

[0069] like Figure 4As shown, further, the two short rods are connected by a pin shaft 306, and the long rod 305 is connected to the short rod by a pin shaft 306. The arrangement of the pin shaft 306 can increase the flexibility of the short rods and the long rod 305 to the short rods, further ensuring the swing effect of the spray head 501, especially for oil stains that are difficult to clean or ink stuck in the staggered grooves, etc., which can be cleaned in all directions by adjusting the swing angle, thereby improving the cleaning effect of the papermaking mesh 1.

[0070] Preferably, if Figure 5 and Figure 6 As shown, the spray head 501 of this embodiment is "L" shaped, and includes a connecting pipe part 5011 and a nozzle 5012 arranged at one end of the connecting pipe part 5011. The connecting pipe part 5011 is connected to an external water source, and the nozzle 5012 faces the papermaking net 1. A connecting piece 5013 is provided at one end of the connecting pipe part 5011 away from the nozzle 5012, and the connecting piece 5013 is hingedly connected to the short rod.

[0071] Specifically, Figure 5 and Figure 6 As shown, the connecting pipe part 5011 is an L-shaped tubular structure. The connecting pipe part 5011 is connected to the external water source through a hose, and the connecting end is arranged parallel to the upper part of the fixed plate 404. The hose can be arranged along the fixed plate 404, and the hose can be fixed to the fixed plate 404 by a strap to avoid confusion of the pipeline. One end of the nozzle 5012 faces the papermaking net 1 for easy spraying. In order to achieve a better spraying effect, the connecting pipe of this embodiment is connected to the external high-pressure water source, and the nozzle 5012 uses a high-pressure nozzle 5012.

[0072] Furthermore, if Figure 6 As shown, the movable part 4012 is connected to a bearing seat 503 which is arranged one-to-one with the spray head 501, and the connecting pipe part 5011 is connected to the inner hole of the bearing seat 503. By setting the bearing seat 503, it is convenient to increase the rotation flexibility of the spray head 501, thereby ensuring the performance of the papermaking net cleaning device of this embodiment.

[0073] like Figure 1 and Figure 2 As shown, as mentioned above, the top of the bracket 2 of this embodiment is provided with a groove 201, and the fixing frame 8 of the papermaking net 1 is provided with a clamping plate 7 extending in the direction of the groove 201. The clamping plate 7 includes a vertical section 701 connected to the top of the fixing frame 8 of the papermaking net 1, and a horizontal section 702 connected to the vertical section 701, and one end of the horizontal section 702 is clamped in the groove 201. In this way, the papermaking net 1 can be quickly fixed on the cleaning device, and the position of the papermaking net 1 can be set at a predetermined position to avoid the situation where the local cleaning cannot be achieved due to positional misalignment.

[0074] The papermaking net cleaning device described in this embodiment drives the spraying mechanism 5 connected to the outside of the papermaking net 1 to drive and operate through the driving mechanism 3, and drives the spraying head 501 to adjust the angle with the papermaking net 1 along the length direction of the papermaking net 1 through the second driving part 4013, which can automatically adjust the pressure of the spraying head 501 on washing oil stains, and adjust the swing of the spraying head 501 along the width direction of the papermaking net 1 through the first driving part 502, which can effectively clean dead corners and improve the cleaning effect of the papermaking net 1, and the structure is simple and the production cost is low.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
