Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, in particular to a cleaning device for producing automobile decorative panels. Background Art

[0002] When injection molding automotive decorative panels, if the mold is not thoroughly cleaned, the residual materials and oil stains from the previous production will adhere to the newly produced panels. During the production process, some additives such as lubricants and plasticizers are added to improve the processing properties of the materials. If these additives are not completely removed or handled improperly in the later stages of production, they may also remain on the surface of the decorative panels and form stains. Therefore, after the panels are processed and produced, they often need to go through a cleaning process before assembly.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The device integrates multiple processes such as spacing, cleaning, turning over and drying into one device. The various components cooperate with each other, making the production process of automotive decorative panels more compact and efficient. The decorative panels go through various processing links on the conveyor belt in sequence, without the need for frequent transfer between different equipment, reducing production time and labor costs, and improving overall production efficiency.

[0016] 2. The spacing assembly can realize the equidistant intermittent conveying of decorative panels through the coordinated work of the spacing plate, spacing pressure rod, spacing guide column, spacing spring and reciprocating slide rod connected to the driving roller. This precise spacing conveying method ensures that each decorative panel has enough space and time to receive uniform treatment in the subsequent cleaning and drying processes, avoiding mutual interference between panels and improving the consistency and quality of treatment.

By properly setting the flip rod, flip fork, flip gear, flip rack and other components, the decorative panel can be accurately flipped 180 degrees under the drive of the reciprocating slide rod. This ensures that both sides of the decorative panel can be fully cleaned and dried, improves the overall quality of the product, and avoids problems such as stain residue or uneven drying that may occur due to single-side processing.

[0019] 5. The drying components and the spacing components are linked by reciprocating slide bars. This linkage mechanism ensures that the coordination between the components is more precise and orderly. Since the movement of each component is related to the movement of the reciprocating slide bar, and the movement of the reciprocating slide bar is indirectly driven by the drive motor, the operation rhythm of the entire device is more coordinated. For example, the intermittent spacing of the spacing component, the hot air supply of the drying component and the conveying speed of the decorative panel can maintain a good matching relationship, avoiding production failures or product quality problems that may be caused by the incoordination between different components.

[0020] 6. The auxiliary cleaning pipe is rotatably connected to the main cleaning pipe, and through the cooperation of the driving rack on the reciprocating slide rod and the incomplete gear on the auxiliary cleaning pipe, the auxiliary cleaning pipe reciprocates, and the cleaning nozzle swings accordingly, realizing the reciprocating spray cleaning of the decorative panel. This dynamic cleaning method avoids the existence of cleaning dead corners and further improves the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-9 , the present invention provides a technical solution: Embodiment 1:

[0025] A cleaning device for automobile decorative panel production is composed of a support frame 1, a conveying assembly 2, a spacing assembly 6, a cleaning assembly 4 and a drying assembly 5. The conveying assembly 2, the spacing assembly 6, the cleaning assembly 4 and the drying assembly 5 are all firmly arranged on the support frame 1, and a turning assembly 8 is cleverly arranged inside the cleaning assembly 4 and the drying assembly 5. The various components cooperate with each other to collaboratively complete a series of processes such as cleaning, turning over and drying of automobile decorative panels.

[0026] The conveying assembly 2 is the part of the whole device responsible for transporting the decorative panels, and it is mainly composed of a driving roller 201, a driven roller 202, a pulley 203 and a conveyor belt 204. The driving roller 201 and the driven roller 202 are rotatably arranged on the support frame 1 by means of axle seats, etc., and a plurality of pulleys 203 are fixedly installed on the driving roller 201 and the driven roller 202. The size and spacing of these pulleys 203 are carefully designed to ensure that the conveyor belt 204 can be driven stably. The conveyor belt 204 is sleeved on the pulleys 203 of the driving roller 201 and the driven roller 202 to form a ring-shaped transport channel.

[0027] In this embodiment, there are two groups of conveyor belts 204, which can stably support the automobile decorative panel.

[0028] In order to provide power to the driving roller shaft 201, a worm gear reducer 205 is also fixedly arranged on the support frame 1. A driving motor 206 is firmly installed at one end of the worm gear reducer 205, and the output shaft of the driving motor 206 is fixedly connected to the input end of the worm gear reducer 205, while the driving roller shaft 201 is fixedly connected to the output end of the worm gear reducer 205.

[0029] When the device is started, the drive motor 206 starts to rotate. The power generated by the drive motor 206 is first transmitted to the worm gear reducer 205. The worm gear reducer 205 plays its deceleration function, reduces the high speed transmitted by the drive motor 206 to a speed suitable for the drive roller 201, and then stably transmits the decelerated power to the drive roller 201. The drive roller 201 starts to rotate after receiving the power. Since the conveyor belt 204 is sleeved on the pulley 203 of the drive roller 201, as the drive roller 201 rotates, the conveyor belt 204 also starts to move, thereby realizing the smooth transportation of the automotive decorative panels placed on the conveyor belt 204.

[0030] In this embodiment, the cleaning component 4 is mainly responsible for cleaning the automobile decorative panel during transportation. It includes a cleaning bracket 401, a water tank 402, a main cleaning pipe 403, a secondary cleaning pipe 404, and a cleaning nozzle 405. The cleaning bracket 401 is firmly fixed on the support frame 1, and the water tank 402 is also arranged on the support frame 1 and is in a suitable relative position with the cleaning bracket 401. A main cleaning pipe 403 is arranged on the cleaning bracket 401, and the main cleaning pipe 403 is the main channel for the transmission of the entire cleaning liquid. A plurality of secondary cleaning pipes 404 are connected to one side of the main cleaning pipe 403, and these secondary cleaning pipes 404 are evenly distributed on one side of the main cleaning pipe 403 to ensure that the cleaning liquid can fully cover the decorative panel. Each secondary cleaning pipe 404 is fixedly connected to a plurality of cleaning nozzles 405 so that the cleaning liquid can be evenly sprayed on the decorative panel.

[0031] In order to extract the cleaning liquid in the water tank 402 and transport it to the cleaning nozzle 405, a support shaft 3 is rotatably arranged on the support frame 1. The support shaft 3 is closely connected with the drive motor 206, that is, the shaft of the drive motor 206 passes through the worm gear reducer 205 and is fixedly connected with the support shaft 3. At the same time, a turbine pump 406 is also fixedly arranged on the support frame 1, and a turbine blade 407 is rotatably arranged inside the turbine pump 406. The support shaft 3 passes through the turbine pump 406 and the turbine blade 407 is fixedly arranged on the support shaft 3. The turbine pump 406 is connected to the main cleaning pipeline 403 and the water tank 402 through a connecting pipe.

[0032] When the device is started and the driving motor 206 rotates, since the shaft of the driving motor 206 is fixedly connected to the supporting shaft 3, the supporting shaft 3 will rotate with the rotation of the driving motor 206. The turbine blades 407 are fixed on the supporting shaft 3, and the rotation of the supporting shaft 3 drives the turbine blades 407 to rotate in the turbine pump 406. The working principle of the turbine pump 406 is to rely on the rotation of the turbine blades 407 to extract the cleaning liquid in the water tank 402 through the connecting pipe, and then pressurize the cleaning liquid and transport it to the main cleaning pipeline 403. After the cleaning liquid enters the main cleaning pipeline 403, it will be diverted to each auxiliary cleaning pipeline 404, and finally sprayed out from the cleaning nozzle 405 on the auxiliary cleaning pipeline 404. The sprayed cleaning liquid will be evenly sprinkled on the car decorative panel being transported on the conveyor belt 204, thereby achieving the cleaning of the decorative panel.

[0033] The drying assembly 5 is mainly used for drying the cleaned automobile decorative panels. It includes a drying bracket 501, a main drying pipe 502, a secondary drying pipe 503, a drying nozzle 504, a fan housing 505, a fan blade 506, a heating chamber 507, a heating rod 508 and other components. The drying bracket 501 is fixedly arranged on the support frame 1, the main drying pipe 502 is installed on the drying bracket 501, one side of the main drying pipe 502 is connected to a plurality of secondary drying pipes 503, and one side of these secondary drying pipes 503 is fixedly connected to a plurality of drying nozzles 504, and the layout of the drying nozzles 504 can make the hot air blow evenly onto the decorative panels.

[0034] A fan casing 505 is fixedly arranged on the support frame 1, and a fan blade 506 is rotatably arranged inside the fan casing 505. The support shaft 3 passes through the fan casing 505, and the fan blade 506 is fixedly arranged on the support shaft 3. The fan casing 505 is connected to the main drying duct 502 through a connecting pipe, and a heating chamber 507 is fixedly connected between the connecting pipe and the main drying duct 502, and a plurality of heating rods 508 are fixedly arranged inside the heating chamber 507, and these heating rods 508 are used to heat the passing airflow.

[0035] When the driving motor 206 rotates, the supporting shaft 3 rotates accordingly. Since the fan blades 506 are fixed on the supporting shaft 3, the fan blades 506 rotate in the fan housing 505. The rotation of the fan blades 506 generates airflow, which flows from the fan housing 505 to the heating chamber 507 through the connecting pipe. When the airflow passes through the heating chamber 507, the heating rod 508 converts electrical energy into thermal energy to heat the passing airflow. The heated airflow continues to flow along the connecting pipe to the main drying duct 502, and then is divided into each auxiliary drying duct 503, and finally ejected from the drying nozzle 504 on the auxiliary drying duct 503. The ejected hot air will blow onto the automobile decorative panel being transported on the conveyor belt 204, thereby achieving the drying of the decorative panel.

[0036] A spacing support rod 601 is fixedly arranged on the support frame 1, and the spacing support rod 601 provides a stable support foundation for the entire spacing assembly 6. A plurality of spacing guide plates 602 are fixedly arranged on the spacing support rod 601, and these spacing guide plates 602 are evenly distributed on the spacing support rod 601, and their positions and spacings are designed according to the size and transportation requirements of the decorative panel.

[0037] Embodiment 2:

[0038] On the basis of the first embodiment, a spacing component 6 is provided in this embodiment, and the spacing component 6 can ensure that in subsequent cleaning, drying and other processes, the decorative panels can be processed in an orderly manner according to a certain spacing, thereby improving the processing efficiency and quality.

[0039] A spacing guide post 603 is slidably provided in the spacing guide plate 602, and the spacing guide post 603 can slide up and down smoothly in the spacing guide plate 602. A spacing plate 604 is fixedly provided at one end of the spacing guide post 603, and the size and shape of the spacing plate 604 match the contact requirements of the decorative panel. A spacing pressure rod 605 is fixedly provided at the other end of the spacing guide post 603, and the design of the spacing pressure rod 605 is convenient for operators to apply external force. A spacing spring 606 is sleeved on the spacing guide post 603, and the spacing spring 606 is located between the spacing plate 604 and the spacing guide plate 602, and the two ends of the spacing spring 606 are in contact with the spacing plate 604 and the spacing guide plate 602 respectively.

[0040] When the spacing spring 606 is in a natural state, the spacing spring 606 will squeeze the spacing plate 604, so that the height of the spacing plate 604 is higher than the height of the conveyor belt 204. In this case, when the decorative panel is transported to the position of the spacing plate 604 along the conveyor belt 204, the decorative panel will be blocked by the spacing plate 604 and stop moving forward.

[0041] When the spacing pressure rod 605 is pressed down, the spacing pressure rod 605 will drive the spacing guide post 603 to slide downward in the spacing guide plate 602. Since the spacing plate 604 is fixed to one end of the spacing guide post 603, the spacing plate 604 will also move downward under the drive of the spacing guide post 603. At this time, the spacing plate 604 no longer hinders the movement of the decorative panel, and the decorative panel can continue to move forward under the transportation of the conveyor belt 204.

[0042] By intermittently pressing the spacing bar 605, the intermittent conveying of the decorative panels can be controlled. Each time the spacing bar 605 is pressed, a decorative panel can pass through the position where the spacing plate 604 is located, thereby realizing the intermittent conveying of decorative panels at equal intervals. This method can ensure that in subsequent cleaning, drying and other processes, the decorative panels can be processed in an orderly manner according to a certain spacing, thereby improving the processing efficiency and quality.

[0043] A reciprocating slide bar 701 is slidably arranged on the support frame 1, and the reciprocating slide bar 701 can perform reciprocating linear motion along a specific direction on the support frame 1. A crank 702 is fixedly arranged at one end of the driving roller shaft 201, and the crank 702 and the reciprocating slide bar 701 are movably connected through a connecting rod 703. The two ends of the connecting rod 703 are respectively connected to the crank 702 and the reciprocating slide bar 701, and this movably connected mode enables the rotation of the crank 702 to be converted into the reciprocating linear motion of the reciprocating slide bar 701.

[0044] A wedge block 607 is fixedly provided on the reciprocating slide bar 701 . The position and shape of the wedge block 607 match the spacing pressure rod 605 . When the reciprocating slide bar 701 performs reciprocating linear motion, the wedge block 607 can interact with the spacing pressure rod 605 .

[0045] When the driving roller shaft 201 starts to rotate, since a crank 702 is fixedly provided at one end of the driving roller shaft 201, the crank 702 rotates together with the driving roller shaft 201. The rotation of the crank 702 drives the reciprocating slide bar 701 to perform reciprocating linear motion on the support frame 1 through the connecting rod 703.

[0046] As the reciprocating slide bar 701 moves back and forth in a straight line, the wedge block 607 on the reciprocating slide bar 701 will intermittently squeeze the separation pressure rod 605. The shape of the wedge block 607 in this embodiment can be set according to specific conditions. The shape of the wedge block 607 can control the falling time and falling stroke of the separation plate 604 in the separation assembly 6. This principle is a basic mechanical principle and is a technology and device well known to technicians in this technical field. When the wedge block 607 moves forward to squeeze the separation pressure rod 605, the separation pressure rod 605 will move downward, thereby driving the separation plate 604 to move downward, so that the decorative panel can pass; when the wedge block 607 moves backward, the separation pressure rod 605 will return to its original position under the action of the separation spring 606, preventing the subsequent automobile decorative panel from moving forward and preparing for the next squeezing.

[0047] Embodiment three:

[0048] On the basis of the above-mentioned embodiment, a flip assembly 8 is provided in this embodiment. The flipping rod 801 in the flipping assembly 8 is rotatably mounted on the support frame 1, and the flipping rod 801 can rotate around a specific axis. A plurality of flipping forks 802 are fixedly mounted on the flipping rod 801, and the shape and spacing of the flipping forks 802 are designed according to the size of the decorative panel and the flipping requirements. A flipping gear 803 is fixedly mounted on one end of the flipping rod 801, and the flipping gear 803 rotates synchronously with the flipping rod 801.

[0049] A flipping rack 804 is fixedly provided at one end of the reciprocating slide 701 , the flipping rack 804 is fixedly connected to the reciprocating slide 701 , and the flipping rack 804 is meshed with the flipping gear 803 .

[0050] When the reciprocating slide bar 701 reciprocates, since the flipping rack 804 is fixed at one end of the reciprocating slide bar 701, the flipping rack 804 will reciprocate along with the reciprocating slide bar 701. Since the flipping rack 804 and the flipping gear 803 are meshed with each other, when the flipping rack 804 moves forward, it will push the flipping gear 803 to rotate; when the flipping rack 804 moves backward, it will drive the flipping gear 803 to rotate in the opposite direction. Since the flipping gear 803 is fixed at one end of the flipping rod 801, the rotation of the flipping gear 803 will drive the flipping rod 801 to rotate together.

[0051] The turning rod 801 has a rotation angle of 180 degrees. When the decorative panel enters the turning fork 802, the decorative panel will be driven by the turning fork 802 as the turning rod 801 rotates back and forth 180 degrees, thereby realizing the turning operation of the decorative panel. In this way, both sides of the decorative panel can be fully cleaned and dried.

[0052] In this embodiment, the operator and the designer can select a flip fork 802 of appropriate size and model according to the actual situation. At the same time, the transmission ratio of the flip rack 804 and the flip gear 803 can be set according to the actual situation and size, so as to control the rotation angle of the flip gear 803 and the flip rod 801 according to the sliding stroke of the reciprocating slide 701, so that it can be flipped exactly one hundred and eighty degrees in one sliding cycle of the reciprocating slide 701. This embodiment only describes the principle and does not limit the specific parameters. This technology is well known to technicians in this technical field and can be implemented by calculation, simulation, etc., and will not be elaborated here.

[0053] At the same time, in this embodiment, there are two groups of auxiliary cleaning pipes 404 in the cleaning component 4, and there are two groups of auxiliary drying pipes 503 in the drying component 5, and the turning component 8 is arranged between the two groups of auxiliary cleaning pipes 404 and the two groups of auxiliary drying pipes 503.

[0054] At the same time, when designing, the designers control the distance between the automobile decorative panels by controlling the shape of the wedge block 607. The distance between the panels matches the flipping cycle of the flipping assembly 8. That is, after the flipping assembly 8 completes a flip and resets, the next panel just enters the flipping fork 802 of the flipping assembly 8.

[0055] At the same time, the opening of the flip fork 802 is set according to actual conditions. Even if the flip gear 803 is rotating all the time, the next panel can enter the flip fork 802 because the opening of the flip fork 802 is properly set.

[0056] Embodiment 4:

[0057] On the basis of the above embodiment, in this embodiment, the auxiliary cleaning pipe 404 and the auxiliary drying pipe 503 are rotated so that they can swing back and forth under the drive of a certain mechanical structure, so that the cleaning and drying effects of the device are better; In the cleaning assembly 4, the auxiliary cleaning pipe 404 is connected to the main cleaning pipe 403 by rotation. The main cleaning pipe 403 serves as the main transmission channel of the cleaning liquid and provides a source of cleaning liquid for the auxiliary cleaning pipe 404. The auxiliary cleaning pipe 404 is rotatably arranged on the cleaning bracket 401 through the shaft seat, and the shaft seat provides a stable support point for the auxiliary cleaning pipe 404 and allows it to rotate around a specific axis.

[0058] An incomplete gear 706 is fixedly connected to one end of the auxiliary cleaning pipe 404. The shape and tooth profile of the incomplete gear 706 are designed according to its special motion requirements. At the same time, a plurality of driving racks 705 are fixedly arranged on the reciprocating slide bar 701. The positions, spacings and tooth profiles of the driving racks 705 match the incomplete gear 706 to ensure that the incomplete gear 706 can be effectively driven to rotate.

[0059] When the reciprocating slide 701 performs a reciprocating linear motion, since the driving rack 705 is fixed on the reciprocating slide 701, the driving rack 705 moves with the reciprocating slide 701. In this process, the driving rack 705 interacts with the incomplete gear 706. When the reciprocating slide 701 moves forward, the driving rack 705 pushes the incomplete gear 706 to rotate a certain angle; when the reciprocating slide 701 moves backward, the driving rack 705 drives the incomplete gear 706 to rotate in the opposite direction by a certain angle.

[0060] Because the incomplete gear 706 is fixedly connected to one end of the auxiliary cleaning pipe 404, the rotation of the incomplete gear 706 will directly drive the auxiliary cleaning pipe 404 to reciprocate around the shaft seat.

[0061] A plurality of cleaning nozzles 405 are fixedly connected to the auxiliary cleaning pipe 404. As the auxiliary cleaning pipe 404 reciprocates, the cleaning nozzles 405 on the auxiliary cleaning pipe 404 also swing back and forth. When the cleaning nozzles 405 swing, the cleaning liquid sprayed from the cleaning nozzles 405 sprays on the decorative panels on the conveyor belt 204 at different angles, thereby achieving reciprocating spray cleaning of the decorative panels. This reciprocating spray cleaning method can clean the decorative panels more comprehensively and thoroughly, avoiding the existence of cleaning dead corners.

[0062] The swinging principle of the drying component 5 is the same as that of the cleaning component 4; In the drying assembly 5, the auxiliary drying duct 503 is rotatably connected to the main drying duct 502. The main drying duct 502 is responsible for guiding the heated airflow to the auxiliary drying duct 503. The auxiliary drying duct 503 is rotatably arranged on the drying bracket 501 through the shaft seat, and the drying bracket 501 provides support for the auxiliary drying duct 503 and defines its rotation center.

[0063] One end of the auxiliary drying pipe 503 is also fixedly connected with an incomplete gear 706. The incomplete gear 706 is similar in principle to the incomplete gear 706 on the auxiliary cleaning pipe 404. It cooperates with the driving rack 705 on the reciprocating slide rod 701 to achieve rotation.

[0064] When the reciprocating slide bar 701 performs reciprocating linear motion, the driving rack 705 on the reciprocating slide bar 701 interacts with the incomplete gear 706 at one end of the auxiliary drying pipe 503. As in the case of the cleaning assembly 4, the reciprocating motion of the reciprocating slide bar 701 causes the driving rack 705 to drive the incomplete gear 706 to reciprocate.

[0065] Since the incomplete gear 706 is fixedly connected to the auxiliary drying pipe 503, the reciprocating rotation of the incomplete gear 706 will drive the auxiliary drying pipe 503 to reciprocate around the shaft seat.

[0066] A plurality of drying nozzles 504 are fixedly connected to the auxiliary drying duct 503. As the auxiliary drying duct 503 reciprocates, the drying nozzles 504 on the auxiliary drying duct 503 also swing back and forth. The hot air ejected from the drying nozzles 504 blows toward the decorative panel on the conveyor belt 204 at different angles, thereby achieving comprehensive drying of the decorative panel and ensuring that all parts of the decorative panel can be evenly dried.

[0067] Embodiment five:

[0068] In the above embodiment, a tensioning assembly 9 is added in this embodiment to tension the conveyor belt 204; A tensioning assembly 9 for tensioning the conveyor belt 204 is provided on the support frame 1. The guide plate 901 in the tensioning assembly 9 is firmly fixed on the support frame 1, and a tensioning guide rod 902 is slidably provided on the guide plate 901, and the tensioning guide rod 902 can slide on the guide plate 901 along a specific direction.

[0069] A tensioning wheel 903 is rotatably provided at one end of the tensioning guide rod 902, and the tensioning wheel 903 can freely rotate around the connection point with the tensioning guide rod 902. A tensioning spring 904 is sleeved on the tensioning guide rod 902, and the two ends of the tensioning spring 904 are respectively in contact with the guide plate 901 and the components near the tensioning wheel 903 (such as the limiting structure on the tensioning guide rod 902). A guide shaft 905 is also rotatably provided on the support frame 1, and the conveyor belt 204 is wound between the pulley 203, the guide shaft 905 and the tensioning wheel 903. This winding method allows the conveyor belt 204 to form a complete transportation loop.

[0070] The tension spring 904 applies a force to the tension guide rod 902 in the initial state, and this force causes the tension wheel 903 to produce a certain pressure on the conveyor belt 204. Since the conveyor belt 204 is wound around the tension wheel 903, this pressure causes the conveyor belt 204 to be in a suitable tensioned state.

[0071] When the conveyor belt 204 becomes loose due to long-term use, temperature changes or other factors, the tension of the conveyor belt 204 will decrease. At this time, under the action of the tension spring 904, the tension guide rod 902 will slide along the guide plate 901, and the tension wheel 903 will move in the direction that can tighten the conveyor belt 204. Because the position of the tension wheel 903 changes, the length of the conveyor belt 204 will change, thereby tightening the conveyor belt 204, restoring the tension of the conveyor belt 204, ensuring that the conveyor belt 204 can operate normally, and preventing the conveyor belt 204 from slipping during operation.

[0072] A waste liquid tank 10 is also fixedly arranged at the position of the support frame 1 below the cleaning assembly 4, so as to effectively collect the sewage generated during the cleaning process of the decorative panel.

[0073] When the cleaning nozzle 405 sprays and cleans the decorative panel, the waste water after cleaning will flow down from the decorative panel. Since the waste liquid tank 10 is located at a suitable position, the waste water will flow into the waste liquid tank 10 under the action of gravity for collection. The collected waste water can be treated by subsequent waste water treatment equipment to meet environmental protection requirements, while also keeping the environment around the cleaning device clean.

[0074] Working principle: During the use of the present invention, the spacing spring 606 in the spacing assembly 6 will squeeze the spacing plate 604 in a natural state, so that the height of the spacing plate 604 is higher than the height of the conveyor belt 204. When the decorative panel is transported to the position of the spacing plate 604 along the conveyor belt 204, the decorative panel will be blocked by the spacing plate 604 and stop moving forward.

[0075] A spacing plate 604 is fixed to one end of the spacing guide post 603, and a spacing pressure rod 605 is provided at the other end. The spacing guide post 603 can slide up and down in the spacing guide plate 602 and is sleeved with a spacing spring 606. When the spacing pressure rod 605 is pressed down, the spacing pressure rod 605 drives the spacing guide post 603 to slide downward in the spacing guide plate 602, and the spacing plate 604 moves downward accordingly, and no longer hinders the movement of the decorative panel, and the decorative panel can continue to move forward under the transportation of the conveyor belt 204.

[0076] The crank 702 at one end of the driving roller shaft 201 is movably connected to the reciprocating slide 701 through the connecting rod 703. When the driving roller shaft 201 rotates, the crank 702 rotates accordingly and drives the reciprocating slide 701 to perform reciprocating linear motion on the support frame 1 through the connecting rod 703. The wedge block 607 on the reciprocating slide 701 is adapted to the spacing pressure rod 605. When the reciprocating slide 701 moves, the wedge block 607 intermittently squeezes the spacing pressure rod 605. When the wedge block 607 moves forward to squeeze the spacing pressure rod 605, the spacing plate 604 falls and the panel passes; when the wedge block 607 moves backward, the spacing pressure rod 605 returns to its original position under the action of the spacing spring 606, preventing the next panel from moving forward, thereby realizing the equidistant and intermittent conveying of decorative panels.

[0077] The driving motor 206 rotates, and its power is transmitted to the driving roller shaft 201 after being decelerated by the worm gear reducer 205. At the same time, the shaft of the driving motor 206 passes through the worm gear reducer 205 and is fixedly connected to the supporting shaft 3. The supporting shaft 3 passes through the turbine pump 406 and the turbine blades 407 are fixed on the supporting shaft 3. The turbine pump 406 is connected to the main cleaning pipeline 403 and the water tank 402 through a connecting pipe. The rotation of the driving motor 206 drives the supporting shaft 3 to rotate, and then drives the turbine blades 407 to rotate. The turbine pump 406 extracts the cleaning liquid in the water tank 402 and pressurizes it and then delivers it to the main cleaning pipeline 403.

[0078] The cleaning liquid in the main cleaning pipe 403 is divided into a plurality of auxiliary cleaning pipes 404, and the cleaning nozzles 405 on the auxiliary cleaning pipes 404 spray the cleaning liquid on the decorative panels on the conveyor belt 204. In the cleaning assembly 4, the driving rack 705 on the reciprocating slide 701 interacts with the incomplete gear 706 at one end of the auxiliary cleaning pipe 404. When the reciprocating slide 701 reciprocates in a straight line, the driving rack 705 drives the incomplete gear 706 to reciprocate, and the incomplete gear 706 drives the auxiliary cleaning pipe 404 to reciprocate around the shaft seat, so that the cleaning nozzles 405 on the auxiliary cleaning pipes 404 swing back and forth, thereby realizing reciprocating spray cleaning of the decorative panels.

[0079] When the reciprocating slide bar 701 reciprocates, the flipping rack 804 fixed at one end of the reciprocating slide bar 701 moves accordingly. The flipping rack 804 meshes with the flipping gear 803 at one end of the flipping rod 801. The flipping rack 804 moves forward to drive the flipping gear 803 to rotate, and moves backward to drive the flipping gear 803 to rotate in the opposite direction, thereby driving the flipping rod 801 to rotate.

[0080] A plurality of turning forks 802 are fixed on the turning rod 801. When the decorative panel enters the turning forks 802, the decorative panel is turned over by the turning forks 802 as the turning rod 801 reciprocates 180 degrees. By reasonably designing the opening of the turning forks 802, the transmission ratio of the turning rack 804 and the turning gear 803, etc., it can be ensured that the next panel can enter the turning forks 802 in time and the turning operation can be completed at the right time, so that both sides of the decorative panel can be fully cleaned and dried.

[0081] Similar to the cleaning assembly 4, the driving motor 206 rotates to drive the support shaft 3 to rotate, the support shaft 3 passes through the fan housing 505 and the fan blades 506 are fixed on the support shaft 3. The fan blades 506 rotate to generate airflow, and the airflow flows from the fan housing 505 to the heating chamber 507 through the connecting pipe. The heating rod 508 in the heating chamber 507 converts electrical energy into thermal energy to heat the airflow. The heated airflow continues to flow along the connecting pipe to the main drying pipe 502.

[0082] The hot air flow in the main drying duct 502 is divided into a plurality of auxiliary drying ducts 503, and the drying nozzles 504 on the auxiliary drying ducts 503 spray the hot air on the decorative panels on the conveyor belt 204. In the drying assembly 5, the driving rack 705 on the reciprocating slide 701 interacts with the incomplete gear 706 at one end of the auxiliary drying duct 503. When the reciprocating slide 701 reciprocates in a straight line, the driving rack 705 drives the incomplete gear 706 to reciprocate, and the incomplete gear 706 drives the auxiliary drying duct 503 to reciprocate around the shaft seat, so that the drying nozzles 504 on the auxiliary drying duct 503 swing back and forth, thereby achieving comprehensive and uniform drying of the decorative panels.

[0083] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
