Background technique

The tufting machine is widely used in drilling and tufting on brush bodies such as daily-use brushes and industrial brushes. The shapes of the brush body and bristles include flat brushes, ball brushes, and hemispherical brushes. For the processing of flat brushes, the drilling and planting worktable of the traditional tufting machine is located below, and the brush body of the flat brush is clamped on the drilling and planting workbench, and the length direction of the flat brush body extends along the width direction of the drilling and planting workbench. The drilling and hair-planting surface of the flat brush body faces upward, and the machine head is located above the drilling and planting workbench. The machine head is equipped with a drilling mechanism and a hair-planting mechanism. The rear side of the machine head is connected to the base, and the machine base extends downward to The drilling and planting workbench is connected on a common base.

When the plane brush is relatively long, the machine head needs to protrude forward for a relatively long distance due to the wide drilling and planting workbench. The cantilever structure leads to a large volume and weight of the overall tufting machine, and the space above the drilling and planting workbench is drilled. Mechanism and tufting mechanism are occupied, and automatic loading and unloading devices cannot be arranged. The loading and unloading of the brush body are all completed by manual assistance, which is labor-intensive and has certain risks. Once the operator makes a mistake, such as failing to remove the brush body that has been planted in time, it will cause interference between the planting nozzle and the brush body, resulting in equipment damage.

After drilling, it continues to turn back to the flocking station for flocking. The material is loaded at the loading and unloading station, and this cycle realizes that the operations of each station are carried out synchronously without interfering with each other.

The above equipment still has the following deficiencies: 1. The brush body must be manually placed on the corresponding station. If the position and orientation of the brush body are placed incorrectly, it will directly lead to subsequent processing failure and waste products.

2. After the wool is planted, it is necessary to go to other equipment to carry out subsequent processes such as flowering, flattening, and grooming, which not only increases the floor space of the production line, but also requires repeated loading, clamping, and unloading, which reduces the overall production efficiency.

Compared with the prior art, the present invention achieves the following beneficial effects: 1. The brush workbench is supported on the corresponding support rails by each roller, the weight of the brush workbench is carried by the middle longitudinal support rails, and the weight of the brush workbench is carried by the upper lateral support rails. , The lower lateral support rail and the auxiliary lateral support rail bear the lateral force and the impact force during drilling or hair planting. Each station rotates clockwise, and the power is supplied to each brush worktable through the central conductive slip ring. The stations do not need to return and rotate, and can work synchronously, achieving zero waiting and high production efficiency.

2. Each station has a four-axis function and is independent of each other. During drilling and hair planting, the loading and unloading stations are still waiting for materials. Speed, different programs are running, and the flowering, flattening and grooming of the bristles are completed in sequence. The bristle finishing station also integrates a spherical brush trimming device to trim the bristles into a standard spherical shape. Finished brushes can be processed in one clamping, avoiding repeated clamping, loading and unloading, etc., greatly improving production efficiency and reducing production costs.

3. The gear ring is connected by four racks and four large gear rings. At the corner, the large gear ring is coaxial with the upper lateral support rail, the middle longitudinal support rail and the lower lateral support rail. The lower lateral support wheels are supported on the inner rail surface of the lower lateral support rail, and the upper lateral support wheels are supported on the outer rail surface of the upper lateral support rail, and are symmetrically located on both sides of the traveling pinion.

The above lateral support wheel is taken as an example, because the rack extends along a straight line, the distance between the line between the axes of the two upper lateral support wheels and the axis of the walking pinion is relatively short; the large ring gear extends along an arc, and the two upper lateral supports The distance between the line between the wheel axes and the axis of the traveling pinion is relatively long. If the relative position between the traveling pinion and the upper lateral support wheel is fixed, it will cause the walking pinion and the rack segment or the large ring gear segment to be out of alignment. meshing problem. For example, the traveling pinion can mesh with the large ring gear, and when turning to the rack section, the traveling pinion will disengage from the rack.

In the present invention, the rotary speed reducer is installed on the floating slide plate. When the brush body table rotates from the arc section to the rack section, the piston rods of the two rotary compensation cylinders stretch out, and the floating slide plate moves inward along the guide rail of the floating slide plate, so that the walking The pinion and the rack mesh well. When the brush body table rotates from the rack section to the arc section, the piston rods of the two rotary compensation cylinders retract, and the floating slides move outward along the guide rails of the floating slides, so that the traveling pinion and the large ring gear can mesh well.

4. Place a brush body between the adjacent partition baffles of the stepping feeding conveyor belt. Regardless of the front and back, regardless of alignment, one brush body can be conveyed to the left in turn, and the positioning cylinder pushes the brush body to the backer through the positioning push plate Make it aligned, and then the brush body slides down the guide frame and falls into the V-shaped groove of the material receiving bracket.

5. The transfer servo motor drives the transfer screw to rotate, and the transfer screw nut takes the transfer bottom plate and the material receiving bracket to move to the left along the transfer guide rail, so that the second material receiving bracket reaches the material receiving position. After the material bracket supports the brush body, it continues to move to the left to the position where it is docked with the rotation correction mechanism.

6. The forward and backward servo motor drives the forward and backward screw through the synchronous wheel and the synchronous belt, and the forward and backward screw nut drives the forward and backward sliding seat to move forward along the forward and backward guide rail, so that the two U-shaped bracket plates reach the top of the material receiving and transferring mechanism; then The transfer cylinder drives the transfer base to rise upwards, so that the brush body rises between the two brush body clamping blocks, and the piston rods of the clamping cylinders on the same side protrude toward each other, driving the L-shaped clamping brackets to move closer together along the clamping guide rails. Until the brush body clip clamps the brush body from both ends. Since the brush body clamping block is provided with a concave inner conical surface, the two inner conical surfaces hold the arc-shaped heads at both ends of the brush body oppositely, so that the automatic centering of the brush body can be realized.

The advance and retreat servo motor drives the advance and retreat slide seat to move and reset along the advance and retreat guide rail through the advance and retreat screw rod. Through image recognition and intelligent calculation, the alignment motor on the same side drives the brush body clamp to rotate synchronously, so that the two brush bodies rotate to the designated orientation.

7. After the synchronous action of the brush bodies on both sides is aligned, the three-dimensional manipulator grabs two brush bodies at a time and sends them to the fixture on the brush body workbench for clamping and fixing. The brush body workbench carries the brush body and rotates around the gear ring for one circle, and after passing through the drilling station, hair planting station and bristle finishing station in turn, it becomes a finished brush, and returns to the loading and unloading station, the fixture of the brush body workbench The brush body is released, and the finished brush falls on the finished product conveyor belt and is sent out backward.

8. The traversing servo motor simultaneously drives the two traversing lead screw synchronous wheels to rotate through the traversing drive wheel and the traversing synchronous belt, and the two traversing lead screw synchronous wheels drive the two traversing lead screws to rotate synchronously, and drives the drill through the screw nut. The planting vertical plate moves forward and backward, and the drilling device and the hair planting device advance and retreat synchronously to adapt to the change of the thickness of the brush body.

9. The center of gravity of the drilling and planting integrated head falls between the two lower guide rails. The C-shaped bracket provides accommodation for the drilling device. The drilling and planting vertical plate is connected to the middle of the drilling and planting floor. On both sides of the vertical board, an upper guide rail is installed on the upper end of the C-shaped bracket to form a more stable support. The upper and lower traversing lead screws are set to act synchronously, so that the traversing movement of the drilling device and the hair planting device is more stable.

10. The drilling device can move left and right along the drilling guide rail, so that the distance between the drill bit and the hair-planting head can be adjusted, and both long brushes and short brushes can meet production requirements. When producing short brushes, the distance between the drill bit and the tufting head is reduced, reducing the displacement of the station switching, saving the time of station switching, and improving production efficiency.

Another object of the present invention is to provide a four-station brush-making integrated machining method for brushes. Each station can perform feeding, drilling, bristle planting, bristle finishing and unloading respectively, and the bristle finishing can complete flowering, Smoothing and grooming, the operation of each station is carried out synchronously without interfering with each other, and the production efficiency is high.

In order to achieve the above object, the four-station brush-making integrated machining method for brushes of the present invention comprises the following steps in turn: the brush body is sent to the material receiving and transferring mechanism one by one by the stepping feeding conveyor belt, and then the brush body is rotated After finding the direction of the brush body with the alignment mechanism, it is grabbed by the three-dimensional manipulator and placed on the brush body worktable on the left side of the rectangular center seat to complete the loading, and then the brush body workbench is rotated 90° to the back of the rectangular circle center seat The drilling station on the side is drilled by the drilling device. After drilling, it advances to the right to the tufting station, and the tufting unit performs the tufting. After the tufting is completed, it continues to turn 180° to the bristle finishing station on the front side of the rectangular center seat. When the front side advances to the left, it goes through flowering, flattening and grooming in sequence, and then continues to turn 90° to return to the loading and unloading station on the left. The material is automatically dropped or the brush is removed by the three-dimensional manipulator and placed on the finished product conveyor. The belt is sent out, and then the three-dimensional manipulator completes the loading of the new brush body at the loading and unloading station, and the cycle is like this.

Compared with the prior art, the present invention achieves the following beneficial effects: each station rotates clockwise, the stations do not need to turn back, and the work can be performed synchronously, zero waiting is realized, and the production efficiency is high. Each station has a four-axis function and is independent of each other. During drilling and hair planting, the loading and unloading station is still waiting for material. Different programs are running, and the flowering, flattening and grooming of the bristles are completed in sequence, and the finished brush can be processed in one clamping, which greatly improves the production efficiency and reduces the production cost.
