Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor belt processing, in particular to an automatic brushing and gluing machine for conveyor belts. Background Art

[0002] The back of the conveyor belt requires a burnt guide strip to serve as a guide and guide. The back of the conveyor belt is the side that contacts the drive pulleys, while the front of the belt contacts the conveyed items. Before applying the burnt guide strip, the cloth on the back needs to be brushed off with a steel brush. Glue is then applied and allowed to dry to enhance the strip's adhesion and prevent it from falling off. Currently, machines that apply glue to conveyor belt bristles require manual adjustment using a hand-cranked wheel before turning on the motor to apply the bristles. This results in a low degree of automation, cumbersome manual steps, large operational errors, and inconsistent brushing depth. Utility Model Content

[0024] A conveyor belt automatic brush glue coating machine, such as Figures 1 to 4 As shown, it includes a control system, a tensioning mechanism 1 and a traction brush gluing mechanism 2. Figure 1As shown, the tensioning mechanism 1 and the traction brush gluing mechanism 2 are arranged side by side, and the tensioning mechanism 1 is used to tension the conveyor belt 3 and guide the transmission of the conveyor belt 3. The traction brush gluing mechanism 2 is used to pull the conveyor belt 3 and automatically brush and gluing the conveyor belt 3.

[0025] Tensioning mechanism 1 Figure 2 As shown, it includes a bracket 11, an auxiliary roller 12, a first tensioning roller 15, a second tensioning roller 16, a first tensioning cylinder 13, and a second tensioning cylinder 14. The bracket 11 is approximately 5 meters long and is welded from channel steel to form a frame structure consisting of multiple beams and columns. The length direction of the bracket 11 is parallel to the horizontal plane. The bracket 11 has two layers, upper and lower, with the first tensioning cylinder 13 and the second tensioning cylinder 14 mounted on the upper and lower layers of the bracket 11, respectively. The drive shafts of the first tensioning cylinder 13 and the second tensioning cylinder 14 are parallel, both parallel to the length direction of the bracket 11. The drive shafts of the first tensioning cylinder 13 and the second tensioning cylinder 14 are connected to one end of the first tensioning roller 15 and one end of the second tensioning roller 16, respectively. The other ends of the first tensioning roller 15 and the second end of the second tensioning roller 16 are cantilevered and extend beyond the bracket 11. The length direction of the drive shaft of the first tensioning cylinder 13 is perpendicular to the length direction of the first tensioning roller 15, and the length direction of the drive shaft of the second tensioning cylinder 14 is perpendicular to the length direction of the second tensioning roller 16. The first tensioning cylinder 13 and the second tensioning cylinder 14 respectively drive the first tensioning roller 15 and the second tensioning roller 16 to reciprocate in a direction parallel to the length direction of the bracket 11, thereby tensioning and loosening the conveyor belt 3 on the first tensioning roller 15 and / or the second tensioning roller 16.

[0026] Preferably, one end of the first tensioning roller 15 is mounted on a support plate 111 via two bearings, the two bearings being spaced apart and arranged in parallel. One end of the first tensioning roller 15 passes through the two bearings. The bracket 11 is provided with two guide rails 112, which are spaced apart and arranged in parallel. The support plate 111 slides on the two guide rails 112. The first tensioning cylinder 13 is connected to and drives the support plate 111 to move back and forth linearly along the guide rails 112.

[0027] A plurality of auxiliary rollers 12 are provided, spaced apart and arranged in parallel, parallel to the length direction of the first tensioning roller 15 and the second tensioning roller 16. The auxiliary rollers 12 are fixedly or rotatably mounted on the bracket 11. The auxiliary rollers 12 are used to change the direction in which the conveyor belt 3 is stretched, thereby allowing the installation and tensioning of conveyor belts 3 of different lengths.

[0028] Traction brush gluing mechanism 2 as Figure 3As shown in FIG4 , the machine comprises a platform 21, a traction assembly, a brush gluing drive, a brush assembly, and a gluing assembly. The platform 21 is located on one side of the support 11, and both the platform 21 and the support 11 are mounted on the ground. The traction assembly provides traction to the conveyor belt 3, enabling the conveyor belt 3 to move. The brush assembly is used to automatically brush the conveyor belt 3. The gluing assembly is used to automatically apply glue to the conveyor belt 3. The brush gluing drive is used to drive the brush assembly and the gluing assembly.

[0029] The traction assembly includes a traction roller 231, a tensioning cylinder 232, a tensioning roller 233, and a reduction motor. The length of the traction roller 231 is parallel to the length of the first tensioning roller 15. The reduction motor is mounted on the machine platform 21 and is connected to and drives the traction roller 231 to rotate. The tensioning roller 233 is located directly below the traction roller 231, and its length is parallel to that of the traction roller 231. The tensioning cylinder 232 is mounted on the machine platform 21 and is located below the tensioning roller 233. The tensioning cylinder 232 is connected to and drives the tensioning roller 233 to rise until it contacts the bottom of the traction roller 231 to compress the conveyor belt 3 passing between the traction roller 231 and the tensioning roller 233, or to drive the tensioning roller 233 to descend to break away from contact with the traction roller 231. Preferably, two tensioning cylinders 232 are provided, and the two tensioning cylinders 232 are connected to the two ends of the tensioning roller 233, respectively. Preferably, both ends of the tightening roller 233 are respectively mounted on two bearings, and the two tightening cylinders 232 are respectively connected to the two bearings directly or through connectors, so that the tightening roller 233 can rotate relative to the machine platform 21 .

[0030] The traction roller 231 and / or the tension roller 233 are provided with support rails 2311 at both ends in the longitudinal direction. The support rails 2311 are used to support the conveyor belt 3 to limit its position, confining the conveyor belt 3 in the width direction between the two support rails 2311 to prevent the conveyor belt 3 from deviating during operation. Preferably, at least one of the support rails 2311 is adjustable to adjust the distance between the two support rails 2311, making the brush glue applicator suitable for conveyor belts 3 of different widths.

[0031] In this embodiment, the traction roller 231 is 1.2 m above the ground.

[0032] As can be seen from the above, the length directions of the traction roller 231, each tensioning roller, and each auxiliary roller 12 are parallel, and among all the rollers, the traction roller 231 is arranged at the end. In other words, the contact between the conveyor belt 3 and the traction roller 231 is surface contact, and the contact surface is an arc surface.

[0033] Based on the above structure, the principle and method of installing and transporting the conveyor belt 3 are as follows: First, the conveyor belt 3 is manually wound around the traction roller 231, the first tensioning roller 15, the second tensioning roller 16, and the auxiliary roller 12 in sequence according to the length of the conveyor belt 3 to be processed. The auxiliary roller 12 to be bypassed can be flexibly selected. The width direction of the conveyor belt 3 is parallel to the length direction of the traction roller 231. The two supporters 2311 at both ends of the traction roller 231 and / or the tensioning roller 233 are adjusted so that the two supporters 2311 contact the two ends of the conveyor belt 3 in the width direction, thereby confining the conveyor belt 3 between the two supporters 2311. Since the traction roller 231 is arranged at the head or tail of all the rollers, the contact surface between the conveyor belt 3 and the traction roller 231 is an arc surface, with a large contact area. Next, the first tensioning cylinder 13 and the second tensioning cylinder 14 are activated, respectively driving the first tensioning roller 15 and the second tensioning roller 16 to contact and tension the conveyor belt 3, thereby tensioning the conveyor belt 3 around the auxiliary roller 12, the first tensioning roller 15, and the second tensioning roller 16. Finally, the reduction motor is activated, driving the traction roller 231 to rotate. The friction between the traction roller 231 and the conveyor belt 3 drives the conveyor belt 3 along its length. If necessary, the tensioning roller 233 is activated, passing the conveyor belt 3 between the traction roller 231 and the tensioning roller 233. The tensioning cylinder 232 is then activated, driving the tensioning roller 233 upward until it clamps the conveyor belt 3 between the traction roller 231 and the tensioning roller 233.

[0034] The brush gluing drive is located on the side of the traction roller 231 away from the tensioning mechanism 1, and the brush gluing drive includes an X-axis linear module 221 and a Y-axis linear module 222. The X-axis linear module 221 and the Y-axis linear module 222 are used to drive the bristle assembly and the gluing assembly. The X-axis linear module 221 is installed on the machine table 21, and the axial direction of the X-axis linear module 221 is parallel to the length direction of the traction roller 231. The Y-axis linear module 222 is installed on the slide of the X-axis linear module 221. The X-axis linear module 221 drives the Y-axis linear module 222 to move back and forth linearly through the slide. The moving direction of the Y-axis linear module 222 is parallel to the length direction of the traction roller 231. The axial direction of the Y-axis linear module 222 is perpendicular to the length direction of the traction roller 231. The bristle assembly and the gluing assembly are both installed on the slide of the Y-axis linear module 222. The Y-axis linear module 222 drives the brush assembly and the glue coating assembly to move back and forth linearly through the slide, and the moving direction is perpendicular to the length direction of the traction roller 231.

[0035] In this embodiment, both the X-axis linear module 221 and the Y-axis linear module 222 are driven by servo motors, and the X-axis linear module 221 is about 1 meter above the ground.

[0036] The bristle assembly includes a bristle motor 241, a brush wheel 242 and a dust cover 243. The bristle motor 241 is installed on the slide of the Y-axis linear module 222. The bristle motor 241 is connected to and drives the brush wheel 242 to rotate. The dust cover 243 moves synchronously with the brush wheel 242 but the dust cover 243 does not rotate. The dust cover 243 is located below the brush wheel 242 and is used to receive impurities brushed off by the brush wheel 242. Preferably, a dust suction port is provided on the side wall of the dust cover 243, which can be connected to a vacuum cleaner pipe to suck away the debris generated during brushing. The axial direction of the brush wheel 242 is parallel to the width direction of the conveyor belt 3. The length of the brush wheel 242 is the same as the width of the burnt guide bar to be processed.

[0037] The glue coating assembly includes a glue coating bracket 251, a lifting cylinder 252, a glue dispensing valve 253, and a glue tank 254. The glue coating bracket 251 is mounted on the slide of the Y-axis linear module 222, and the lifting cylinder 252 is mounted on the glue coating bracket 251. The lifting cylinder 252 is connected to and drives the glue dispensing valve 253 to move up and down. The glue dispensing valve 253 is located above the traction roller 231. The line connecting the glue dispensing port of the glue dispensing valve 253 and the brush wheel 242 is perpendicular to the length direction of the traction roller 231, that is, the projection of this line on the conveyor belt 3 is parallel to the transmission direction of the conveyor belt 3. This ensures that the brushing trajectory of the brush wheel 242 on the conveyor belt 3 and the glue coating trajectory of the glue dispensing valve 253 on the conveyor belt 3 coincide with each other. The glue tank 254 is located on the machine 21. The glue tank 254 is filled with glue. The dispensing valve 253 and the glue tank 254 are connected by a pipeline. When applying glue, the dispensing valve is opened and air is ventilated to the air inlet of the glue tank 254 at the same time, so that the air pressure in the glue tank 254 increases and the glue is squeezed out from the glue outlet hole, and then flows out from the dispensing port of the dispensing valve 253 and falls on the conveyor belt 3.

[0038] As can be seen from the above, the positional relationship between the tensioning mechanism 1, the brush assembly, and the glue coating assembly is as follows: the movement direction of the Y-axis linear module 222 relative to the machine 21 is parallel to the length direction of the traction roller 231, and the movement direction of the brush assembly and the glue coating assembly relative to the Y-axis linear module 222 is perpendicular to the length direction of the traction roller 231. Therefore, the brush assembly and the glue coating assembly can move in two directions parallel and perpendicular to the length of the traction roller 231 relative to the bracket 11 and the machine 21, and both directions are parallel to the horizontal plane. In addition, the dispensing valve 253 can also rise or fall under the drive of the lifting cylinder 252, that is, the dispensing valve 253 can move in three-dimensional directions perpendicular to each other. Preferably, the central axis of the brush wheel 242 is parallel to the central axis of the traction roller 231 and has the same height.

[0039] The control system includes a PLC, an HMI human-machine interface, a servo drive, a frequency converter, a solenoid valve, etc., which are used to control the movements of each motor and cylinder. The telescopic movements of the drive shafts of the tightening cylinder 232, the first tightening cylinder 13, and the second tightening cylinder 14 are each controlled by the solenoid valves connected to them. The moving distance or final position of the slide of the X-axis linear module 221 and the slide of the Y-axis linear module 222 can be manually input through the HMI human-machine interface. The control program is input through the PLC, so that each electrical component operates according to the set logic. The above components and working principles are all existing technologies and will not be repeated here.

[0040] Based on the above structure, the working principle and process of the utility model are as follows: First, the conveyor belt 3 is turned inside out and installed on the tensioning mechanism 1 and the traction roller 231, with the side to be brushed and glued facing outward. The reduction motor is started to drive the traction roller 231 to rotate, thereby driving the conveyor belt 3. In this way, the back side of the conveyor belt 3 to be brushed and glued faces outward, facilitating the brushing and gluing operation. Then, the X-axis and Y-axis positions of the conveyor belt 3 to be brushed and glued are set on the HMI human-machine interface, and the start button is pressed to start automatic brushing and gluing. Specifically, in the first step, the X-axis linear module 221 drives the Y-axis linear module 222 to move to the set position in a direction parallel to the length of the traction roller 231 and the width of the conveyor belt 3; in the second step, the brush motor 241 drives the brush wheel 242 to rotate; in the third step, the Y-axis linear module 222 drives the brush motor 241 to move to the set position, and the brush wheel 242 contacts the conveyor belt 3 and starts brushing. At this time, the dispensing valve 253 does not contact the conveyor belt 3. The brushing position is the position where glue will be applied and the burning guide strip will be installed. In this step, since the center axis of the brush wheel 242 and the center axis of the traction roller 231 are at the same height, the brush wheel 242 can contact the conveyor belt 3 by simply moving horizontally in a direction perpendicular to the width of the conveyor belt 3, as shown in FIG. Figure 5 As shown. In the fourth step, after the brushing time reaches the set time, the brush motor 241 stops. In this step, the brushing time is set according to the transmission speed of the conveyor belt so that the brush wheel 242 completes at least one circle of brushing. In the fifth step, the Y-axis linear module 222 drives the brush motor 241 to move in the opposite direction to the set position, and the brush wheel 242 breaks away from contact with the conveyor belt 3. In the sixth step, the lifting cylinder 252 drives the dispensing valve 253 to descend and start applying glue. When the set gluing time is reached, the dispensing valve 253 closes and rises, the X-axis linear module 221 and the Y-axis linear module 222 return to their initial positions, and the gluing process ends.

[0041] Finally, it is necessary to explain here that the above embodiments are only used to further illustrate the technical solution of the utility model in detail and cannot be understood as limiting the scope of protection of the utility model. Some non-essential improvements and adjustments made by technicians in this field based on the above content of the utility model are all within the scope of protection of the utility model.
