Description

Technical Field

[0001] The invention relates to the technical field of cleaning wiper rubber strips, and in particular to cleaning equipment for producing and preparing rubber products. Background Art

[0002] The wiper is an important accessory installed on the windshield. The wiper rubber strip is pressed against the glass surface by a spring strip to remove rain, snow and dust on the windshield that obstructs the view. It plays an important role in driving safety.

[0003] During the current production of wiper rubber strips, it is usually necessary to first cut a groove in the raw rubber strip, and then pickle the rubber strip to roughen its surface for subsequent graphite spraying processing. However, after pickling, the grooved rubber strip is prone to retain a large amount of pickling agent on the rough surface in the groove. Currently, the pickled rubber strip is mostly cleaned by soaking and rinsing with clean water. This cleaning method easily causes some pickling agent to remain on the rough surface in the groove of the rubber strip. The chemical components in the residual pickling agent will react with the rubber, thereby affecting its elasticity and durability. In the subsequent wiping process, scratches may also be left on the glass, affecting the clarity of vision. In addition, the wiper rubber strip is often in a stretched state during daily use, so higher requirements are placed on the tensile strength of the wiper rubber strip to ensure the performance and service life of the wiper rubber strip. Therefore, a cleaning device for the production and preparation of rubber products is proposed. Summary of the invention

[0036] Example, see Figures 1 to 11 A cleaning device for rubber product production and preparation comprises a reel 1 and a cleaning chamber 2, a reel assembly for reeling in a rubber strip is arranged outside the reel 1, and an inner side wall of the reel 1 is connected to a limited slot column 8 through an arc light panel 7;

[0037] Further, the winding roller assembly is composed of a driving gear 4, a driven gear 5 and a winding roller 6. The outer wall of the winding roller 1 is fixedly connected to the end of the driving gear 4 through the driving motor 3. The driving gear 4 is meshed with the driven gear 5. The end of the driven gear 5 is fixedly connected to the inner wall of the winding roller 6 through the winding shaft. The inner wall of the winding roller 1 is fixedly connected to the outer arc side wall of the arc light panel 7. The inner arc side wall of the arc light panel 7 is fixedly connected to the side wall of the slot limiting column 8. The inner arc side wall of the arc light panel 7 is a smooth surface.

Since the inner arc surface of the arc-shaped light panel 7 is a smooth surface, the friction between it and the rubber belt is extremely small, and the rubber belt is driven by the squeezing of the winding roller 6, and the groove on it will be pressed and expanded in the process of the rubber belt being squeezed and wound;

[0039] The above advantages are: it is convenient to open the groove surface of the rubber belt later, so that the pickling agent in the groove of the rubber belt can be cleaned more easily;

This is prior art and will not be described in detail here. The electrically controlled lifting plate 20 is connected to a clamping assembly for limiting the side wall of the rubber strip groove through a pneumatic push rod 21, and a belt pressing plate 28 for limiting the outer wall of the rubber strip is provided on the clamping assembly. The lower side walls of both ends of the belt pressing plate 28 are provided with limiting grooves, and magnetic limiting assemblies are provided in the limiting grooves;

[0041] Furthermore, a micro hydraulic pump for pressing in a cleaning water flow is arranged in the cleaning box 9, the output end of the air-drying air pump 12 is connected to the side wall of the adapter right-angle tube 10 through an air pipe, the two sides of the adapter right-angle tube 10 are connected to the two bottom ends of the outer cleaning cover 17 through two side branch tubes 11, the top of the adapter right-angle tube 10 is rotatably connected to the end of the tank cleaning tube 13, the spin assembly is composed of a fixed filter plate 14 and a spinning impeller 15, the inner side wall of the end of the tank cleaning tube 13 is fixedly connected to the side wall of the fixed filter plate 14, the shaft end of the spinning impeller 15 is fixedly connected to the end face of the fixed filter plate 14, the top of the outer cleaning cover 17 is fixedly connected to a hydraulic cylinder 16, the two bottom ends of the outer cleaning cover 17 are slidably connected to four slide seats 19 through two electrically controlled guide rails 18, and the inner end face of the outer cleaning cover 17 is fixedly connected to a sliding guide column 25. The outer side wall of the sliding guide column 25 is fixedly connected to the top of the belt pressing plate 28 through the sliding half ring 26 and the adjusting telescopic rod 27. The clamping assembly is composed of a groove outer splint 22 and a groove inner splint 24. The side wall of the electric control lifting plate 20 is fixedly connected to one side wall of the groove outer splint 22 through a pneumatic push rod 21. The other side wall of the groove outer splint 22 is fixedly connected to the side wall of the groove inner splint 24 through two tightening poles 23. Two slots are provided on the other side wall of the top of the groove outer splint 22. The magnetic limit assembly is composed of a docking electromagnetic plate 29 and a limiting electromagnetic plate 31. The top of the groove outer splint 22 is made of magnet material. The inner side wall of the limiting groove of the belt pressing plate 28 is provided with a receiving groove. The inner end surface of the receiving groove is fixedly connected to the end of the limiting electromagnetic plate 31 through two reset spring rods 30. The limiting electromagnetic plate 31 is adapted to the slot.

[0042] It should be noted that the rolled-in rubber belt will enter the upper side wall of the end of the groove cleaning tube 13 close to the curved light panel 7. Since the rubber belt is in a bent state at this time, it will be pressed and positioned on the groove cleaning tube 13. At this time, the pneumatic push rod 21 is used to push the outer groove clamping plate 22 and the inner groove clamping plate 24 inward, and the inner groove clamping plate 24 will squeeze the edge of the rubber belt into the groove at the head end of the rubber belt. Then, the tightening pole 23 is controlled to drive the inner groove clamping plate 24 to retract, limit the two side walls of the groove at the end of the rubber belt and pull it to unfold. Then, the infrared sensor used for positioning between the outer groove clamping plate 22 and the belt pressing plate 28 is used to control the slide 19 to slide slowly in the electric control guide rail 18. When the infrared sensor between the outer groove clamping plate 22 and the belt pressing plate 28 is aligned and sensed, The control slide 19 stops moving, so that the outer clamping plate 22 of the groove is aligned with the limiting groove below the belt pressing plate 28, and then the docking electromagnetic plate 29 and the limiting electromagnetic plate 31 in the limiting groove of the belt pressing plate 28 are energized in turn, so that the top of the outer clamping plate 22 of the groove enters the limiting groove of the belt pressing plate 28 under the magnetic attraction of the docking electromagnetic plate 29, and the limiting electromagnetic plate 31 is magnetically attracted and inserted into the slot on the side wall of the outer clamping plate 22 of the groove. The power-on time of the limiting electromagnetic plate 31 is changed according to the thickness of the rubber belt to facilitate its entry into the slots at different positions, so that the upper part of the rubber belt is pressed and limited by the belt pressing plate 28, so that the entire rubber belt is pulled out under the drive of the slide 19 fixing the head end of the rubber belt, and the tail end of the rubber belt is limited and fixed in the same way;

[0043] When the rubber belt is in a normal unfolding state, the two slide seats 19 on the same electric control guide rail 18 are controlled to move slowly in opposite directions at the same time, so that the rubber belt will be slowly stretched and unfolded. At this time, the groove surface and the rough surface on the outside of the rubber belt will be enlarged and unfolded, and then the part where the pickling agent is easily hidden will be enlarged and unfolded. Then the hydraulic pump in the cleaning box 9 is controlled to input the cleaning water into the adapter right-angle pipe 10. During this process, the air pipe valve connected to the air-drying air pump 12 is in a closed state and is not affected. The cleaning water will pass through the adapter right-angle pipe 10 and enter the outer cleaning cover 17 through the two side branch pipes 11 respectively, and directly enter the tank cleaning pipe 13. When the water flow enters the tank cleaning pipe 13, it will impact the spinning impeller 15 on the fixed filter plate 14. The rotation of the spinning impeller 15 through the fixed filter plate 14 will drive the entire tank cleaning pipe 13 to rotate together, thereby performing a circular flushing on the groove surface of the rubber belt, and the outer cleaning cover 17 will flush the entire outer side surface of the rubber belt;

[0044] The above advantages are: by pulling the rubber belt slowly and slightly, the part of the rubber belt where the pickling agent is easily hidden can be enlarged and spread out, so that the pickling agent on the entire rubber belt can be quickly and completely cleaned and removed, thereby ensuring the subsequent elasticity and life of the rubber belt;

[0045] The inner side wall of the bottom end of the winding cylinder 1 is connected to a test cavity seat 32 through an electric push rod, the top of the test cavity seat 32 is connected to an outward expansion inclined frame 33 for opening the groove of the rubber strip, and the inner end surface of the test cavity seat 32 is connected to a test air pump 34 and two air pressure sensors 35;

[0046] Furthermore, two air pressure sensors 35 are symmetrically arranged on the inner end surface of the test cavity seat 32, a drainage hole is opened at the bottom of the cleaning chamber 2, a protective hole plate 36 is fixedly connected to the inner wall of the drainage hole, and a drainage inclined guide plate 37 is arranged below the protective hole plate 36;

[0047] It should be noted that: after the rubber belt is cleaned, the slide seat 19 is slid to perform a tensile test on the wet rubber belt with a strength slightly higher than that of daily use. After the tensile test is completed, the outer cleaning cover 17 is lifted upward by the hydraulic cylinder 16 to separate the outer cleaning cover 17 from the side branch pipe 11. The rapid assembly and separation between the pipe and the pipe mouth is a prior art and will not be described in detail here. Then the entire rubber belt will be lifted upward, and the control will push the test cavity seat 32 to the middle part of the entire rubber belt. The middle part of the stretched rubber belt is slightly concave inward, and then the rubber belt is pressed against the outward expansion inclined frame 33 by the electrically controlled lifting plate 20 on the slide seat 19. The groove in the middle part of the rubber belt is stretched and pressed against the outward expansion inclined frame 33, and then the test air pump 34 is started to fill the test cavity seat 32 with constant gas. The air pressure changes in the test cavity seat 32 during the test are monitored by the air pressure sensors 35 on both sides. If the air pressure in the test cavity seat 32 decreases, it means that the middle part of the rubber belt, which is most vulnerable to damage during the stretching process, has cracks or partial fractures. If the rubber belt is not damaged, the rubber belt is restored to its initial state and initial position, and the rubber belt is quickly air-dried by the airflow of the air-drying air pump 12. Then, the rubber belt is subjected to the same tensile test as above with a strength slightly higher than that of daily use in a nearly dry state;

[0048] The above advantages are: in this way, the tensile test of the use strength can be carried out in the wet state and the nearly dry state of the rubber belt, simulating the state of the wiper in daily use on rainy days and sunny days, and the pressure change of the test cavity seat 32 in the state of the rubber belt being compressed and sealed can be used to intuitively detect the tiny cracks and local fracture defects in the tensile test, so that the use strength of the produced rubber belt is guaranteed;

[0049] When the present invention is in use, the wiper rubber belt to be cleaned and the pickling agent removed is placed on the inner arc surface of the arc light panel 7, and the groove of the rubber belt is kept in a matching connection with the groove limiting column 8. At the same time, the driving motor 3 is started to drive the driving gear 4 to rotate. The rotation of the driving gear 4 will drive the meshing driven gear 5 to rotate. The rotation of the driven gear 5 drives the winding roller 6 to rotate through the winding shaft. Since the inner arc surface of the arc light panel 7 is a smooth surface, the friction between it and the rubber belt is extremely small. Therefore, the rubber belt will slide downward on the inner arc surface of the arc light panel 7 under the extrusion and drive of the winding roller 6. In the process of the rubber belt being squeezed and wound, the groove on it will be pressed and unfolded, which can facilitate the subsequent opening of the groove surface of the rubber belt, so that the pickling agent in the groove of the rubber belt can be more easily cleaned.

[0050] The rolled-in rubber belt will enter the upper side wall of the end of the groove cleaning tube 13 close to the curved light panel 7. Since the rubber belt is in a bent state at this time, it will be pressed and positioned on the groove cleaning tube 13. At this time, the pneumatic push rod 21 is used to push the outer groove clamping plate 22 and the inner groove clamping plate 24 inward, and the inner groove clamping plate 24 will squeeze the edge of the rubber belt into the groove at the head end of the rubber belt. Then, the tightening pole 23 is controlled to drive the inner groove clamping plate 24 to retract, limit the two side walls of the groove at the end of the rubber belt and pull it to unfold, and then use the infrared sensor for positioning between the outer groove clamping plate 22 and the belt pressing plate 28 to first control the slide 19 to slide slowly in the electric control guide rail 18, and wait for the infrared sensor between the outer groove clamping plate 22 and the belt pressing plate 28 to When the alignment is sensed, the control slide 19 stops moving, so that the outer clamping plate 22 of the groove is aligned with the limiting groove below the belt pressing plate 28, and then the docking electromagnetic plate 29 and the limiting electromagnetic plate 31 in the limiting groove of the belt pressing plate 28 are energized in turn, so that the top of the outer clamping plate 22 of the groove enters the limiting groove of the belt pressing plate 28 under the magnetic attraction of the docking electromagnetic plate 29, and the limiting electromagnetic plate 31 is magnetically attracted and inserted into the slot on the side wall of the outer clamping plate 22 of the groove. The power-on time of the limiting electromagnetic plate 31 is changed according to the thickness of the rubber belt, so that it is convenient for it to enter the slot at different positions, so that the upper part of the rubber belt is pressed and limited by the belt pressing plate 28, so that the entire rubber belt can be pulled out later under the drive of the slide 19 fixing the head end of the rubber belt;

[0051] The tail end of the rubber belt is fixed in the same way. When the rubber belt is in a normal unfolded state, the two slide seats 19 on the same electric control guide rail 18 are controlled to move slowly in opposite directions at the same time, so that the rubber belt will be slowly stretched and unfolded. At this time, the groove surface and the rough surface on the outside of the rubber belt will be enlarged and unfolded, thereby enlarging and unfolding the part where the pickling agent is easily stored. Then, the hydraulic pump in the cleaning box 9 is controlled to input the cleaning water into the adapter right-angle pipe 10. During this process, the air pipe valve connected to the air-drying air pump 12 is in a closed state and is not affected. The cleaning water passes through the two side branch pipes 11 through the adapter right-angle pipe 10. The water flows into the outer cleaning cover 17 and directly into the tank cleaning pipe 13. When the water flows into the tank cleaning pipe 13, it impacts the self-spinning impeller 15 on the fixed filter plate 14. The self-spinning impeller 15 rotates through the fixed filter plate 14 to drive the entire tank cleaning pipe 13 to rotate together, thereby performing annular flushing on the groove surface of the rubber belt. The outer cleaning cover 17 flushes the entire outer side surface of the rubber belt. In this way, the rubber belt can be slowly and slightly pulled to enlarge and expand the part where the pickling agent is easily hidden on the rubber belt, so that the pickling agent on the entire rubber belt can be quickly and completely cleaned and removed, thereby ensuring the subsequent elasticity and life of the rubber belt.

[0052] After the rubber belt is cleaned, the rubber belt in a wet state is subjected to a tensile test with a strength slightly higher than that of daily use through the sliding of the slide 19. After the tensile test is completed, the outer cleaning cover 17 is lifted upward by the hydraulic cylinder 16, so that the outer cleaning cover 17 is separated from the side branch pipe 11. The rapid assembly and separation between the pipeline and the pipe mouth is a prior art and will not be described in detail here. Then the entire rubber belt will be lifted upward, and the control will push the test cavity seat 32 to the middle part of the entire rubber belt. The middle part of the stretched rubber belt is slightly concave inward, and then the rubber belt is pressed against the outward expansion oblique frame 33 by the electrically controlled lifting plate 20 on the slide 19, so that the groove in the middle part of the rubber belt is stretched and pressed against the outward expansion oblique frame 33, and then the test air pump 34 is started to fill the test cavity seat 32 with constant gas, and the air pressure changes in the test cavity seat 32 during the test are monitored by the air pressure sensors 35 on both sides;

[0053] Based on the above, if the air pressure in the test cavity seat 32 decreases, it means that cracks or local fractures have appeared in the middle part of the rubber belt that is most vulnerable to damage during the stretching process. If the rubber belt is not damaged, the rubber belt is restored to its original state and initial position, and the rubber belt is quickly dried by the airflow of the air drying air pump 12. Then, the rubber belt is subjected to the same tensile test as above in a nearly dry state with a strength slightly higher than that of daily use. In this way, the tensile test of the use strength can be performed on the rubber belt in a wet state and a nearly dry state, simulating the state of the wiper in daily use on rainy and sunny days. The air pressure change of the test cavity seat 32 when the rubber belt is compressed and sealed can be used to intuitively detect the tiny cracks and local fracture defects in the tensile test, so that the use strength of the produced rubber belt is guaranteed.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
