Description

Technical Field

[0001] The invention relates to the technical field of felt grinding processing, in particular to a grinding head processing machine for felt production and a processing method thereof. Background Art

[0002] When the hard felt is butted, the staff needs to grind it first to make the end of the hard felt beveled to increase the contact area between the two hard felts, and then apply high-performance water-based composite glue on the beveled surface, and finally press it. At present, the bevel grinder is a more common processing machine used for grinding the bevel of hard felt.

[0003] A Chinese patent discloses a felt grinding joint processing device (authorization announcement number CN215104181U), which sets a collection mechanism to make the exhaust fan blades rotate with the rotation of the grinding roller, thereby reducing the pressure in the feed rod, so that the debris generated by grinding enters the collection box through the feed rod, thereby achieving the effect of collecting the debris.

[0004] According to the above reference cases, the above device uses a collecting mechanism to enable the exhaust fan blades to suck the grinding debris as the grinding roller rotates. Since the exhaust fan blades are arranged on one side of the grinding roller, it can only suck the debris close to the grinding roller, and it is difficult to effectively clean the debris polished by the grinding roller, resulting in a lot of debris still remaining on the felt and the grinding body, affecting the subsequent processing difficulty and quality of the felt.

[0009] Furthermore, a square groove is provided at one end of the transmission shaft, and the reciprocating adjustment module includes a gear shaft inserted into the square groove, a protective shell is provided on the surface of the gear shaft, a fourth spur gear rotatably connected to the protective shell is meshed on the surface of the gear shaft, a gear ring rotatably connected to the protective shell is meshed on the surface of the fourth spur gear, a circular shaft is slidably connected to the inner side of the gear ring, both ends of the circular shaft pass through the protective shell, one end of the circular shaft is fixedly connected to the dust filter box, an annular wave groove is provided on the surface of the circular shaft, and a guide block fixedly connected to the gear ring is slidably connected to the inner side of the annular wave groove.

[0010] Furthermore, the cross-sectional shape of the chip extraction port is a cone-shaped bucket, and the inner diameter of the chip extraction port gradually narrows from the grinding roller toward the dust filter box.

[0011] Furthermore, the vertical cross-section of the inner side of the dust filter box is in the shape of a right-angled hexagon, and the cross-sectional dimension of the opening of the dust filter box is larger than the cross-sectional dimension of the connection point between the chip extraction port and the filter channel.

[0012] Furthermore, the vertical cross-sectional shapes of the inner sides of the dust filter box and the filter channel are both matching rectangles, and the inner horizontal length of the filter channel is greater than the horizontal length of the dust filter box.

[0013] Furthermore, the cross-sectional shapes of the annular wave groove and the guide block are both matching arc shapes.

[0014] Furthermore, the square groove and the connecting portion between the gear shaft and the square groove are both matching rectangles.

[0017] The above-mentioned grinding head processing machine for felt production and the processing method thereof use uniformly arranged chip extraction ports and synchronously driven impeller wheels to uniformly suck the chips ground out of the lower surface of the grinding roller, which can ensure that the chip extraction ports constantly suck out the chips ground out of the corresponding parts of the grinding roller, which effectively improves the cleaning rate of the chips, so that the grinding roller and the belt conveyor are always kept clean, thereby reducing the impact on the subsequent hard felt processing; While the servo motor drives all the fan rims through the drive adjustment component, the drive adjustment component can synchronously reciprocate and shake the dust filter box to avoid the accumulation of debris in a certain place inside the dust filter box. This not only enables each chip extraction port to be in an unobstructed state to ensure the collection rate of the debris generated by grinding, but also enables the debris to be evenly spread on the inner bottom wall of the dust filter box, so that the dust filter box can accommodate more debris, and the frequency of cleaning the debris inside the dust filter box is effectively reduced, thereby improving the processing efficiency of the bevel of the end of the hard felt.

[0026] Combine the following Figure 1 - Figure 8 The present invention describes a grinding head processing machine for felt production and a processing method thereof.

[0027] In one embodiment, a grinding head processing machine for felt production includes a belt conveyor 100, the top of the belt conveyor 100 is fixedly connected to a frame 200, the top of the frame 200 is fixedly connected to an electric cylinder 300, and the bottom of the electric cylinder 300 is fixedly connected to a grinding mechanism 400; The conveyor belt used in the belt conveyor 100 can be an endless mesh belt made of magnetic metal, which not only makes it convenient for workers to use fixed pins to fix the hard felt, but also enables the permanent magnet to adsorb and fix the hard felt on the top of the endless mesh belt, allowing workers to easily lock the hard felt.

[0028] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the grinding mechanism 400 includes an arc shell 410 fixedly connected to the bottom of the electric cylinder 300, a grinding roller 420 is rotatably connected inside the arc shell 410, one end of the grinding roller 420 is fixedly connected to a servo motor 430 fixedly connected to the arc shell 410, the inner side of the arc shell 410 is provided with uniformly distributed chip extraction ports 411, one end of the arc shell 410 is provided with a filtering channel 412 connected to the chip extraction port 411, the inner side of the chip extraction port 411 is rotatably connected to a fan wheel rim 440, and the other end of the grinding roller 420 is fixedly connected to the servo motor 430 fixedly connected to the arc shell 410. A driving adjustment assembly 450 is connected and fixedly connected to the impeller rim 440, a dust filter box 460 is inserted into the interior of the filter channel 412, the impeller rim 440 includes a rotating drum rotatably connected to the interior of the chip extraction port 411, an impeller is fixedly connected to the interior of the rotating drum, and the axis of the impeller is fixedly connected to the second bevel gear 456. The impeller here is the same as the impeller currently used in the fan, and is a common structure used by technicians in this field to guide airflow. The specific material and model need to be selected according to actual usage requirements and will not be elaborated here.

[0029] The cross-sectional shape of the chip extraction port 411 is conical, and the inner diameter of the chip extraction port 411 gradually narrows from the grinding roller 420 toward the dust filter box 460, which can gather the adsorbed airflow together to increase the overall flow rate of the airflow; the vertical cross-sectional shape of the inner side of the dust filter box 460 is a right-angled hexagon, and the cross-sectional size of the opening of the dust filter box 460 is larger than the cross-sectional size of the connection between the chip extraction port 411 and the filter channel 412, which can increase the dust filter box 460 The collection rate of debris to increase the capacity for debris; the vertical cross-sectional shapes of the inner sides of the dust filter box 460 and the filter channel 412 are both matching rectangles, and the inner horizontal length of the filter channel 412 is greater than the horizontal length of the dust filter box 460, which can prevent the probability of the dust filter box 460 being offset and rotated during operation, and the Shudie dust filter box 460 can stably filter debris.

[0030] When the debris enters the interior of the filter channel 412 through the chip extraction port 411, the dust filter box 460 can filter the debris and confine it therein, so that clean airflow is discharged. This can not only reduce the debris being trapped in the fan wheel rim 440 or the drive adjustment assembly 450 to ensure the cleanliness of the entire operating environment, but also can collect the debris in a centralized manner for subsequent centralized processing by the staff.

[0031] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the driving adjustment assembly 450 includes a first spur gear 451 fixedly connected to the other end of the grinding roller 420, the surface of the first spur gear 451 is meshedly connected with a second spur gear 452 rotatably connected to the circular arc shell 410, the surface of the second spur gear 452 is meshedly connected with a third spur gear 453, one end of the third spur gear 453 is fixedly connected with a transmission shaft 454 rotatably connected to the circular arc shell 410, the surface of the transmission shaft 454 is fixedly connected with uniformly distributed first bevel gears 455, the surface of the first bevel gear 455 is meshedly connected with a second bevel gear 456 fixedly connected to the impeller rim 440, and one end of the transmission shaft 454 is clamped with a reciprocating adjustment module 457 rotatably connected to the dust filter box 460; During the rotation of the grinding roller 420, the grinding roller 420 drives the first spur gear 451 to rotate, the first spur gear 451 drives the second spur gear 452 to rotate in the opposite direction, the second spur gear 452 drives the third spur gear 453 to rotate in the opposite direction, the third spur gear 453 drives the transmission shaft 454 to rotate, the transmission shaft 454 drives all the first bevel gears 455 to rotate, the first bevel gear 455 drives the second bevel gear 456 to rotate, and the second bevel gear 456 drives the impeller rim 440 to rotate. At this time, all the impeller rims 440 synchronously suck the air inside the corresponding chip extraction port 411 to ensure that the debris can be effectively cleaned.

[0032] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, a square groove 4541 is provided at one end of the transmission shaft 454, and the reciprocating adjustment module 457 includes a gear shaft 4571 inserted into the square groove 4541. A protective shell 4572 is sleeved on the surface of the gear shaft 4571. A fourth spur gear 4573 rotatably connected to the protective shell 4572 is meshed and connected on the surface of the gear shaft 4571. A gear ring 4574 rotatably connected to the protective shell 4572 is meshed and connected on the surface of the fourth spur gear 4573. A circular shaft 4575 is slidably connected to the inner side of the gear ring 4574. Both ends of the circular shaft 4575 pass through the protective shell 4572. One end of the circular shaft 4575 is fixedly connected to the dust filter box 460. An annular wave groove 45751 is provided on the surface of the circular shaft 4575. A guide block 4576 fixedly connected to the gear ring 4574 is slidably connected inside the annular wave groove 45751. The cross-sectional shapes of the groove 45751 and the guide block 4576 are both matched arc shapes, which can reduce the resistance of the guide block 4576 moving inside the annular wave groove 45751, and the dust filter box 460 can reciprocate more smoothly; the square groove 4541 and the connecting parts of the gear shaft 4571 and the square groove 4541 are both matched rectangles, which can prevent the gear shaft 4571 from rotating relative to the square groove 4541 during the connection with the square groove 4541, so as to ensure that the transmission shaft 454 can stably drive the gear shaft 4571 to rotate; one end of the gear shaft 4571 is rotatably connected with a bolt 4577, and one end of the bolt 4577 passes through the gear shaft 4571 and is rotatably connected to the square groove 4541, which can stably lock the gear shaft 4571 inside the square groove 4541, so that the dust filter box 460 can stably reciprocate; During the rotation of the transmission shaft 454, the transmission shaft 454 drives the gear shaft 4571 to rotate through the square groove 4541, the gear shaft 4571 drives the fourth spur gear 4573 to rotate, the fourth spur gear 4573 drives the gear ring 4574 to rotate, the gear ring 4574 drives the guide block 4576 to rotate, and the guide block 4576 reciprocates the circular shaft 4575 through the annular wave groove 45751 during the rotation, and the circular shaft 4575 drives the dust filter box 460 to swing back and forth in the filter channel 412, which can shake off the debris that is concentrated and blocked in a certain place of the dust filter box 460, and avoid a certain chip extraction port 411 being blocked by debris, so as to ensure that each chip extraction port 411 can circulate air normally, and further improve the effective collection rate of the debris polished out by the grinding roller 420; When the staff needs to clean the debris inside the dust filter box 460, the staff only needs to unscrew the bolt 4577 from the square groove 4541. At this time, the gear shaft 4571 is no longer blocked, and the staff can use the protective shell 4572 to remove the gear shaft 4571 and the dust filter box 460 from the square groove 4541 and the filter channel 412 respectively, and the staff can clean the debris normally.

[0033] like Figure 1-8As shown, a felt processing method, the specific processing method of the felt processing method is as follows: 1. Spread the hard felt flat on the top of the belt conveyor 100, and then fix the hard felt on the top of the belt conveyor 100 by fixing nails or magnetic blocks, and then manually control the belt conveyor 100 to move the end of the hard felt to be polished to the bottom of the polishing roller 420; Second, the electric cylinder 300 is manually controlled to extend, and the electric cylinder 300 drives the grinding roller 420 to move downward through the arc shell 410 until the lower surface of the grinding roller 420 contacts the top surface of the hard felt; 3. Manually control the servo motor 430 to drive the grinding roller 420 to rotate and grind the hard felt, and at the same time manually control the electric cylinder 300 to drive the grinding roller 420 to move downward. At this time, the electric cylinder 300 drives the rotating grinding roller 420 through the arc shell 410 to gradually deepen the depth of the hard felt, and manually control the belt conveyor 100 to drive the hard felt to move back, which can increase the range of the grinding roller 420 grinding the hard felt, so that the grinding roller 420 gradually tilts and rises to grind the hard felt, so that the grinding roller 420 gradually grinds one end of the hard felt to the inclined surface; Fourth, reset and stop the belt conveyor 100 , the electric cylinder 300 and the servo motor 430 , then remove the structure for fixing the hard felt, and finally remove the hard felt from the top of the belt conveyor 100 .

[0034] Working principle: When the servo motor 430 drives the grinding roller 420 to rotate and grind the end of the hard felt, the servo motor 430 drives all the impeller rims 440 to rotate by driving the adjustment component 450. The impeller rims 440 rotate to stir the air inside the chip extraction port 411 and guide it outward. At this time, negative pressure is generated in the chip extraction port 411 and the airflow inside the arc shell 410 is sucked. At this time, the passing airflow can quickly suck away the debris polished by the grinding roller 420. Since the chip extraction ports 411 are evenly arranged on the inner side of the arc shell 410, and each chip extraction port 411 is individually equipped with an impeller rim 440, this can ensure that the chip extraction port 411 constantly sucks the debris polished by the corresponding part of the grinding roller 420, which effectively improves the cleaning rate of the debris, so that the grinding roller 420 and the belt conveyor 100 are always kept clean, so as to reduce the impact on subsequent hard felt processing.

[0035] It should be noted that the belt conveyor 100, electric cylinder 300 and servo motor 430 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the belt conveyor 100, electric cylinder 300 and servo motor 430 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
