Description

Technical Field

[0001] The present invention relates to the technical field of saw blade processing, and particularly relates to a socketing device for a band saw blade tooth protection sleeve. Background Art

[0002] During the production, transportation, and sales of band saw blades, the saw teeth are often directly exposed without necessary protection measures. In this case, collisions are likely to occur between band saw blades, resulting in tooth filing and tooth damage, seriously affecting the quality and cutting efficiency of band saw blades. Therefore, after the production of band saw blades is completed, a plastic glue sleeve or a hard plastic sleeve needs to be used to wrap the outside of the saw teeth to avoid tooth filing and wear between the saw teeth.

[0003] The Chinese patent with the publication number CN210649319U discloses a socketing device for a band saw blade tooth protection sleeve. A first roller, a second roller, a sheath guiding plate, and a third roller are respectively arranged from the right side to the left side of the connecting plate. A V-shaped groove is arranged on the side of the first roller, and a V-shaped convex edge is arranged on the side of the second roller. The sides of the first roller and the second roller are matched, and two groups of the first roller and the second roller are arranged obliquely. The upper mouth of the sheath guiding plate is V-shaped convex, and the sheath guiding plate corresponds to the position between the first roller and the second roller. A third roller is arranged obliquely below the sheath guiding plate, and a V-shaped groove is arranged on the side of the third roller. Although the above patent can socket the tooth protection sleeve on the saw teeth of the band saw blade, each time an operator needs to manually operate the conveying tool to control the band saw blade to callback a certain distance to reserve the socketing area of the tooth protection sleeve, and then manually control the cutting tool to cut off the tooth protection sleeve to complete the final socketing of the band saw blade. Moreover, the cut-off tooth protection sleeve needs to be manually fine-tuned in position to ensure its subsequent precise alignment with the band saw blade. Manual operation increases the complexity of the process, reduces the socketing efficiency, and due to the existence of human factors, may lead to inconsistent adjustments, affecting the final socketing quality of the tooth protection sleeve.

[0004] The present invention aims to solve the problems existing in the above patent. Therefore, a socketing device for a band saw blade tooth protection sleeve is proposed, which can automatically cut off the tooth protection sleeve and socket it on the tooth surface of the band saw blade, and convey the remaining tooth protection sleeve to a designated position, without manual operation, improving the socketing efficiency and quality.

When the positioning component is in operation, the positioning component can realize positioning support for the tooth guard being conveyed.

[0029] Please refer to Figure 2 As shown, the auxiliary component includes a guiding roller 8, a pressing roller 9 and a conveyor 91. Two guiding rollers 8 are rotatably connected to the right side of the front surface of the electric movable frame 6. The two guiding rollers 8 correspond to the two driving rollers 10 respectively. When the tooth guard sleeve moves, the guiding roller 8 can guide the tooth guard sleeve. A pressing roller 9 is rotatably connected to the left side of the front surface of the electric movable frame 6. When the band saw blade moves, the pressing roller 9 can press the tooth guard sleeve tightly on the tooth surface of the band saw blade. A conveyor 91 is installed on the right side of the top of the workbench 1. When the conveyor 91 operates, the conveyor 91 can drive the band saw blade to move and be sleeved with the tooth guard sleeve.

[0030] Please refer to Figures 4-6 As shown, the positioning component includes a positioning plate 11, a return spring 1101, an n-shaped plate 111, a wire conduit 112, a wire 1121, an iron block 113 and a locking component. The positioning plate 11 is slidably inserted through the right side of the electric movable frame 6. The positioning plate 11 is inclined. When the positioning plate 11 moves left and downward, the positioning plate 11 can position and support the tooth guard sleeve. The driving roller 10 rotatably penetrates the positioning plate 11. A return spring 1101 is connected between the right rear part of the positioning plate 11 and the inner side of the electric movable frame 6. An n-shaped plate 111 is fixedly connected to the lower part of the front surface of the electric movable frame 6. The inner side of the n-shaped plate 111 is slidably connected to the positioning plate 11. When the positioning plate 11 moves, the n-shaped plate 111 can guide the positioning plate 11. A wire conduit 112 is fixedly connected to the lower left side of the inner front surface of the electric movable frame 6. A wire 1121 is connected to the right side of the positioning plate 11. The tail end of the wire 1121 passes through the wire conduit 112 and is fixedly connected to an iron block 113. The bottom end of the iron block 113 contacts the end of the wire conduit 112. A locking component is arranged between the support column 4 and the electric lifting frame 5. The locking component contacts the iron block 113, and the locking component can suck and lock the iron block 113; The locking component includes an electromagnet 114, an adjustable L-shaped plate 115 and a button 116. An electromagnet 114 is installed on the top of the electric lifting frame 5. The electromagnet 114 contacts the iron block 113, and the electromagnet 114 can suck the iron block 113. An adjustable L-shaped plate 115 is installed on the lower right side of the right side surface of the support column 4. A button 116 is installed on the outer top right side of the adjustable L-shaped plate 115. The button 116 is located below the electric lifting frame 5. The button 116 and the electromagnet 114 are electrically connected through a control module.

[0031] Initially, the electromagnet 114 holds and fixes the iron block 113 by magnetic force. First, place the band saw blade between the guiding platform 2 and the conveyor 91, start the conveyor 91 to move and contact the band saw blade. Twist the adjustable L-shaped plate 115 according to the height of the band saw blade to drive the button 116 to move up and down. When the button 116 moves up and down to a suitable position, stop twisting the adjustable L-shaped plate 115. Then move the tooth guard sleeve between the driving roller 10 and the guiding roller 8, and make the tooth guard sleeve located below the electric cutter 7 and the pressing roller 9. Then start the electric movable frame 6 to move forward and downward. The electric movable frame 6 drives the tooth guard sleeve to move forward and downward through the driving roller 10 and the guiding roller 8. At the same time, the electric movable frame 6 moving forward and downward drives the wire conduit 112 to move forward and downward. Since the electromagnet 114 holds and fixes the iron block 113, the pull wire 1121 is in a static state. The forward and downward movement of the wire conduit 112 squeezes the pull wire 1121, causing the pull wire 1121 to drive the positioning plate 11 to move left and downward. The return spring 1101 is compressed. The positioning plate 11 moves left and downward through the n-shaped plate 111 and is located inside the tooth guard sleeve. The left end of the positioning plate 11 is on the right side of the pressing roller 9. The positioning plate 11 positions and supports the tooth guard sleeve to prevent the position of the tooth guard sleeve from shifting and affecting the subsequent sleeving on the band saw blade, thus ensuring the precise sleeving of the tooth guard sleeve. At the same time, the electric movable frame 6 also drives the worm 103 to move forward and downward. The worm 103 drives the one-way gear 104 to move forward and downward. The one-way gear 104 moving forward and downward meshes with the rack 105. The rack 105 drives the one-way gear 104 to rotate idly. The idling of the one-way gear 104 does not drive the worm 103 to rotate. When the electric movable frame 6 moves forward and downward to the maximum stroke, turn off the electric movable frame 6. The tooth guard sleeve and the one-way gear 104 stop moving forward and downward. At this time, the tooth guard sleeve is directly above the band saw blade, and the one-way gear 104 disengages from the rack 105. Subsequently, start the electric lifting frame 5 to move downward and drive the electric movable frame 6 to move downward. The downward movement of the electric movable frame 6 drives the tooth guard sleeve to move downward through the guiding roller 8 and the driving roller 10. The electric movable frame 6 also drives the pressing roller 9 and the positioning plate 11 to move downward synchronously. The positioning plate 11 moves downward and sleeves on the band saw blade, and the pressing roller 9 moves downward to press the tooth guard sleeve against the tooth surface of the band saw blade for sleeving. At the same time, when the electric lifting frame 5 moves downward and contacts the button 116, the button 116 controls the electromagnet 114 to turn off through the control module. The electromagnet 114 turns off and stops holding the iron block 113. Due to the action of the return spring 1101, the positioning plate 11 moves right and upward to reset. The positioning plate 11 resets and disengages from the band saw blade. Subsequently, the operator can start the conveyor 91 to drive the band saw blade to rotate forward. The forward rotation of the band saw blade drives the tooth guard sleeve to move left. The pressing roller 9 continuously presses the left-moving tooth guard sleeve onto the band saw blade for sleeving. At the same time, start the vision inspection machine 101 to take pictures and inspect the tooth surface condition of the band saw blade. As the band saw blade is continuously rotated forward and sleeved with the tooth guard sleeve, when the end of the tooth guard sleeve driven by the band saw blade rotates forward to the front side of the vision inspection machine 101,The visual inspection machine 101 takes a picture and detects the end of the tooth guard. The visual inspection machine 101 controls the electric cutter 7 to start through the control module. The electric cutter 7 moves downward to cut off the tooth guard. Subsequently, the cut tooth guard continues to move leftward and is sleeved on the band saw blade. At this time, the two ends of the tooth guard on the band saw blade come into contact with each other to complete the final sleeving. The conveyor 91 is turned off, and the electric lifting frame 5 is started to move upward, driving the electric movable frame 6 to move upward and reset. The upward movement of the electric movable frame 6 drives the remaining tooth guards to move upward and reset through the driving roller 10 and the guiding roller 8. Then, the electric movable frame 6 is started to move backward and upward to reset. The electric movable frame 6 drives the one-way gear 104 to move backward and upward through the worm 103. The one-way gear 104 meshes with the rack 105. The rack 105 drives the one-way gear 104 to rotate forward. The forward rotation of the one-way gear 104 drives the worm 103 to rotate forward. The forward rotation of the worm 103 drives the worm gear 102 to rotate reversely. The reverse rotation of the worm gear 102 drives the left driving roller 10 to rotate reversely. The reverse rotation of the left driving roller 10 drives the right driving roller 10 to rotate reversely through the synchronous belt assembly. The reverse rotation of the left and right driving rollers 10 drives the remaining tooth guards to move leftward and downward through the guiding roller 8, so that the tooth guards move to the lower part of the pressing roller 9 and are in the use position. The one-way gear 104 continues to move backward and upward to reset and disengages from the rack 105. The one-way gear 104 stops rotating forward, and the driving roller 10 stops driving the tooth guards to move leftward and downward. At the same time, the electric movable frame 6 drives the iron block 113 to move backward and upward to reset and contact the electromagnet 114 through the wire conduit 112. The electromagnet 114 continues to attract the iron block 113. In this way, the tooth guard can be automatically cut and sleeved on the band saw blade, and the remaining tooth guards can be conveyed to the use position without manual operation, thereby improving the sleeving efficiency and quality. Subsequently, the operator starts the conveyor 91 to loosen the band saw blade, and then removes the band saw blade sleeved with the tooth guard from the guiding table 2 and the conveyor 91, places the next band saw blade between the guiding table 2 and the conveyor 91, and the tooth guard can be sleeved on the band saw blade again according to the above operation.,

[0032] Please refer to Figures 7-9As shown in the figure, the tooth guard sleeve socketing device of the band saw blade further includes a feeding component installed on the electric movable frame 6. The feeding component includes a fixed frame 12, an electric rotating cylinder 121, a guiding ring 122, an electric conveying wheel 123, a pressing component, a photoelectric inductor 126, and a pushing component. A fixed frame 12 is fixedly connected to the right side surface of the electric movable frame 6. An electric rotating cylinder 121 is installed on the front side of the fixed frame 12. Guide rings 122 are symmetrically and fixedly connected to the upper and lower sides on the right side of the outer side surface of the electric rotating cylinder 121. The guide rings 122 can guide the tooth guard sleeve. Electric conveying wheels 123 are symmetrically installed on the upper and lower sides on the left side of the electric rotating cylinder 121. When the electric conveying wheels 123 rotate reversely, the electric conveying wheels 123 can drive the tooth guard sleeve to move leftward onto the driving roller 10. A photoelectric inductor 126 is installed on the upper right side of the front side surface of the positioning plate 11. Both the electric conveying wheels 123 and the electric rotating cylinder 121 are electrically connected to the photoelectric inductor 126 through a control module. A pressing component is arranged on the left side of the electric rotating cylinder 121. When the pressing component operates, the pressing component can press and guide the tooth guard sleeve. A pushing component is arranged on the electric rotating cylinder 121. When the pushing component operates, the pushing component can drive the positioning plate 11 to move leftward, so that the positioning plate 11 can position and support the tooth guard sleeve during feeding. The pressing component includes an L-shaped rod 124, a connecting spring 1241, and a guiding wheel 125. L-shaped rods 124 are symmetrically and slidably connected to the upper and lower sides on the left side of the electric rotating cylinder 121. Guide wheels 125 are rotatably sleeved on the ends of the upper and lower L-shaped rods 124 that are away from each other. The guiding wheels 125 can press and guide the tooth guard sleeve. Connecting springs 1241 are connected between the ends of the upper and lower L-shaped rods 124 that are close to each other and the inner side of the electric rotating cylinder 121. The pushing component includes an electric push rod 127 and a pushing block 128. An electric push rod 127 is installed inside the electric rotating cylinder 121. The telescopic end of the electric push rod 127 is fixedly connected to the pushing block 128. The pushing block 128 is located on the right side of the positioning plate 11. When the pushing block 128 moves leftward and contacts the positioning plate 11, the pushing block 128 can drive the positioning plate 11 to move leftward.

[0033] When the dental guard needs to be placed, first pass the two dental guards through the upper and lower guiding rings 122 respectively, and make the dental guards be between the electric conveying wheel 123 and the guiding wheel 125. Then push the upper dental guard to move leftward to be between the driving roller 10 and the guiding roller 8 for subsequent use. When the dental guard on the driving roller 10 moves leftward and sleeves on the band saw blade, start the photoelectric inductor 126. The photoelectric inductor 126 detects the dental guard on the driving roller 10. Whenever the dental guard on the driving roller 10 is used up, the photoelectric inductor 126 does not detect the dental guard on the driving roller 10. The photoelectric inductor 126 first controls the electric rotating cylinder 121 to rotate 180 degrees through the control module. The electric rotating cylinder 121 drives the electric conveying wheel 123 and the guiding ring 122 to rotate 180 degrees. The lower guiding ring 122 rotates 180 degrees to drive the lower dental guard to rotate 180 degrees to be in the upper position for use. Subsequently, the photoelectric inductor 126 controls the electric conveying wheel 123 to reverse through the control module. The reverse rotation of the electric conveying wheel 123 drives the dental guard to move leftward to be between the driving roller 10 and the guiding roller 8 through the guiding wheel 125 for subsequent use. Due to the action of the connecting spring 1241, the guiding wheel 125 presses and guides the dental guard more stably to prevent the dental guard from separating from the electric conveying wheel 123 and affecting the feeding. At the same time, start the electric push rod 127. The telescopic rod of the electric push rod 127 extends to drive the push block 128 to move left and downward. The push block 128 moves left and downward to contact the positioning plate 11. The push block 128 drives the positioning plate 11 to move left and downward. The return spring 1101 is compressed. The positioning plate 11 moves left and downward to continue to position and support the dental guard. When the dental guard moves left and downward to the use position, turn off the electric conveying wheel 123, and the dental guard stops moving left and downward. Start the electric push rod 127 to drive the push block 128 to move right and upward to reset. The push block 128 resets and separates from the positioning plate 11. Due to the action of the return spring 1101, the positioning plate 11 moves right and upward to reset. Subsequently, the operator can pass the next dental guard through the lower guiding ring 122, and make the dental guard pass through the lower electric conveying wheel 123 and the lower guiding wheel 125. In this way, the feeding and sleeving of the dental guard on the band saw blade can be completed without stopping the machine, thereby further improving the sleeving efficiency of the dental guard.

[0034] Please refer to Figure 10 As shown, the band saw blade dental guard sleeving device further includes a connecting rod 13 and a guiding plate 14. Connecting rods 13 are fixedly connected to both the fixed part and the moving part of the conveyor 91. Guiding plates 14 are fixedly connected to the front and rear connecting rods 13 symmetrically left and right. When the guiding plate 14 moves and contacts the band saw blade, the guiding plate 14 can guide the movement of the band saw blade.

[0035] When the band saw blade is placed between the guide table 2 and the conveyor 91, the band saw blade is between the front and rear guide plates 14. When the conveyor 91 moves into contact with the band saw blade, the moving part of the conveyor 91 drives the rear guide plate 14 to move forward through the rear connecting rod 13. The rear guide plate 14 moves forward into contact with the band saw blade. The rear guide plate 14 and the front guide plate 14 cooperate to correct the deviation and position of the band saw blade, so that the position of the band saw blade under the tooth protection sleeve is in a straight state. When the tooth protection sleeve is sleeved on the band saw blade, start the conveyor 91 to move back to disengage from the band saw blade. The conveyor 91 drives the rear guide plate 14 to move backward and reset through the rear connecting rod 13, and the rear guide plate 14 resets to disengage from the band saw blade. In this way, it can prevent the position of the band saw blade under the tooth protection sleeve from being skewed, which affects the accurate sleeving of the tooth protection sleeve, thus ensuring that the tooth protection sleeve is normally sleeved on the band saw blade.
