Description

Technical Field

[0001] The invention relates to the technical field of printer rubber roller processing, in particular to a printer rubber roller processing shaft threading device. Background Art

[0002] With the rapid development of the printing industry, the demand for printer rubber rollers has continued to increase, and higher requirements have been placed on their quality and production efficiency. The printer rubber roller consists of an external rubber roller and a core rod inside the rubber roller. The current production process is to first coat the core rod with glue, and the external rubber roller is extruded by an extruder, and when it is extruded, it is just wrapped around the outside of the core rod.

[0003] In the existing printer rubber roller processing technology, the shaft threading process mostly adopts a combination of mechanical and manual operation. Manual shaft threading not only consumes a lot of manpower costs, but also has extremely low work efficiency, which is difficult to meet the growing market demand. At the same time, it is difficult to ensure the coaxiality of the core rod and the rubber roller by manual operation, which can easily cause serious quality problems such as loose bonding between the rubber roller and the core rod. In addition, when the core rod is manually inserted into the unexpanded rubber roller, due to the large resistance, the rubber roller often moves axially, further affecting the stability and consistency of product quality. Therefore, the development of a device that can achieve automatic, efficient and accurate shaft threading has become a key issue that needs to be urgently solved in the printer rubber roller processing industry. Summary of the invention

[0004] The purpose of the present invention is to provide a printer rubber roller processing and shaft threading device to solve the technical problems raised in the background technology.

Detailed implementation manners

[0030] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] The left, right, up and down positions of each component shown in the drawings are only a layout method, and the specific positions are set according to specific needs.

[0032] In one embodiment, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7As shown in the figure, a shaft-passing device for processing a printer rubber roller includes a rubber roller belt conveying mechanism, a shaft-passing frame body 300, a mandrel pushing mechanism 600, a V-shaped pressing component 500, and a glue coating component 700. The rubber roller belt conveying mechanism includes a belt conveying component 100, two guiding oval plates 200, and a plurality of V-shaped bracket components 400. The two guiding oval plates 200 are symmetrically arranged on both sides of the belt conveying component 100. A plurality of V-shaped bracket components 400 are arranged on the upper side of the guiding oval plates 200 and are connected to the belt conveying component 100. Under the action of the belt conveying component 100, the V-shaped bracket components 400 move along the edges of the guiding oval plates 200. The V-shaped bracket components 400 are used to support the rubber roller 900 extruded by an extruder. The shaft-passing frame body 300 is horizontally arranged above the belt conveying component 100, and a rubber roller pressing cylinder 310 is arranged on the shaft-passing frame body 300. The V-shaped pressing component 500 is arranged at the lower end of the rubber roller pressing cylinder 310. The V-shaped pressing component 500 can cooperate with the V-shaped bracket components 400 to clamp the rubber roller 900 and blow inflation air into the rubber roller 900. The mandrel pushing mechanism 600 is arranged on the side of the belt conveying component 100 and corresponds to the shaft-passing frame body 300. The mandrel pushing mechanism 600 includes a shaft-passing main frame body 610, an inclined feeding table 620, a V-shaped feeding part 630, and a shaft-passing pushing component 650. The shaft-passing main frame body 610 is installed at the end of the shaft-passing frame body 300 extending to one side of the belt conveying component 100. The inclined feeding table 620 is fixed on the shaft-passing main frame body 610, and the inclined feeding table 620 is used to store the mandrel 800. The V-shaped feeding part 630 is arranged at the lower end of the inclined feeding table 620 so that the mandrel 800 automatically rolls into the V-shaped feeding part 630. The shaft-passing pushing component 650 is arranged above the V-shaped feeding part 630, and the shaft-passing pushing component 650 is connected to the shaft-passing frame body 300. The shaft-passing pushing component 650 is used to push the mandrel 800 in the V-shaped feeding part 630 towards the belt conveying component 100. The glue coating component 700 is arranged between the V-shaped feeding part 630 and the belt conveying component 100 and is connected to the shaft-passing main frame body 610. The mandrel 800 in the V-shaped feeding part 630 can pass through the glue coating component 700, and the glue coating component 700 coats glue on it. An alignment confirmation part is also arranged on the outer wall of the guiding oval plate 200, and the alignment confirmation part is electrically connected to the power source of the belt conveying component 100. When the V-shaped bracket component 400 moves to directly below the V-shaped pressing component 500, the alignment confirmation part can play a damping role in the movement of the V-shaped bracket component 400 and control the power source of the belt conveying component 100 to stop.

[0033] In an embodiment of the present invention, the extruded rubber roller 900 is transported to the V-shaped bracket component 400 by a manipulator or manually, etc. The belt conveying component 100 operates to cause multiple V-shaped bracket components 400 to reciprocally move in a cycle along the outer edge of the guiding oval plate 200, and the rubber roller 900 moves along with the V-shaped bracket component 400. When the V-shaped bracket component 400 moves to the shaft-passing area (i.e., directly below the V-shaped pressing component 500), the alignment confirmation part can damp the movement of the V-shaped bracket component 400 and control the power source of the belt conveying component 100 to stop. At this time, the belt conveying component 100 stops operating and the V-shaped bracket component 400 no longer moves, and the V-shaped bracket component 400 is directly below the V-shaped pressing component 500. The rubber roller pressing cylinder 310 operates to drive the V-shaped pressing component 500 to move downward. The V-shaped pressing component 500 cooperates with the V-shaped bracket component 400 to clamp the rubber roller 900, and one end of the V-shaped pressing component 500 acts on the end of the rubber roller 900 away from the mandrel pushing mechanism 600 and blows expansion air into its interior. The rubber roller 900 starts to expand. The mandrel 800 is on the inclined feeding table 620 and the inclined feeding table 620 is in an inclined state. The foremost mandrel 800 automatically rolls into the V-shaped feeding part 630. At this time, the V-shaped feeding part 630 is in an aligned state with the V-shaped bracket component 400 in the shaft-passing area, and the mandrel 800 and the rubber roller 900 respectively located in the two are coaxial. The shaft-passing pushing component 650 and the glue coating component 700 start to operate. The shaft-passing pushing component 650 starts to push the mandrel 800 from one end to make the mandrel 800 move towards the rubber roller 900. The mandrel 800 passes through the glue coating component 700 and the glue coating component 700 rotates to coat a part of the circumferential surface of the mandrel 800 located therein. The mandrel 800 after being coated with glue can be correspondingly inserted into the interior of the rubber roller 900. Since the rubber roller 900 expands under the action of the V-shaped pressing component 500, the resistance for the mandrel 800 to be inserted into the rubber roller 900 is relatively small, and axial movement of the rubber roller 900 can be avoided. After the mandrel 800 is completely inserted into the interior of the rubber roller 900, the V-shaped pressing component 500 stops blowing air into the interior of the rubber roller 900. The rubber roller 900 contracts and completes bonding with the circumferential surface of the mandrel 800. After the shaft-passing is completed, the shaft-passing pushing component 650 retracts to its original position, the foremost mandrel 800 on the inclined feeding table 620 automatically rolls into the V-shaped feeding part 630, the rubber roller pressing cylinder 310 operates to drive the V-shaped pressing component 500 away from the V-shaped bracket component 400. At the same time, the belt conveying component 100 continues to operate and moves the next V-shaped bracket component 400 to the shaft-passing area to facilitate the next set of shaft-passing operations, thereby realizing automatic shaft-passing work and effectively improving work efficiency. The setting of the alignment confirmation part can achieve automatic positioning in the horizontal direction and ensure that the mandrel 800 is accurately inserted into the interior of the rubber roller 900.

[0034] In one embodiment, as Figure 1 、 Figure 6 and Figure 7As shown, the main shaft-passing frame body 610 is vertically slidably engaged with the shaft-passing frame body 300. An upper adjusting cylinder part 320 is provided on the shaft-passing frame body 300, and the telescopic part of the upper adjusting cylinder part 320 is connected to the rubber roller pressing cylinder 310. In the embodiment of the present invention, the upper adjusting cylinder part 320 can drive the main shaft-passing frame body 610 to move vertically on the shaft-passing frame body 300 through its own telescopic movement, so as to slightly adjust the height of the main shaft-passing frame body 610, and further slightly adjust the heights of the inclined feeding table 620 and the V-shaped feeding part 630, so as to ensure that the V-shaped feeding part 630 is aligned with the V-shaped bracket component 400 in the height direction.

[0035] In one embodiment, as Figures 1-4 shown, the V-shaped bracket component 400 includes a V-shaped supporting part 410 and two lower sliding seats 420. The V-shaped supporting part 410 is horizontally arranged above the belt conveying component 100 and is used to support the rubber roller 900. The two lower sliding seats 420 are respectively slidably engaged with the outer edges of the two guiding waist-shaped plates 200. A belt connecting rod 430 is further provided on the lower sliding seat 420, and the belt connecting rod 430 is connected to the belt conveying component 100. An alignment acting part is further provided on the side of the lower sliding seat 420. When the V-shaped bracket component 400 moves to directly below the V-shaped pressing component 500, the alignment acting part can act on the alignment confirmation part. In the embodiment of the present invention, the belt conveying component 100 includes an outer bracket 110, two belt pulley parts 120, and a belt part 130 wound around the outside of the two belt pulley parts 120. The main shafts of the two belt pulley parts 120 pass through the centers of the arc ends of the guiding waist-shaped plates 200 and are rotationally matched with the outer bracket 110. A conveying motor is provided on the outer bracket 110. The conveying motor is electrically connected to the alignment confirmation part to control the rotation state of the belt pulley part 120. The belt part 130 has a transverse skeleton inside, and the transverse skeleton is connected to the belt connecting rod 430 in each V-shaped bracket component 400. The function of the transverse skeleton can increase the strength of the belt part 130 and prevent the belt part 130 from being misaligned due to the damping of the movement of the V-shaped bracket component 400. The belt pulley part 120 rotates under the drive of the conveying motor, and the belt part 130 moves cyclically under the drive of the two belt pulley parts 120. The belt part 130 drives the V-shaped supporting part 410 and the lower sliding seat 420 to move in a surrounding manner along the outer edge of the guiding waist-shaped plate 200 through the belt connecting rod 430. When the V-shaped bracket component 400 moves to directly below the V-shaped pressing component 500, the alignment acting part can act on the alignment confirmation part. The alignment confirmation part controls the conveying motor to stop working, so that the V-shaped bracket component 400 stops moving in the shaft-passing area for subsequent shaft-passing work.

[0036] In one embodiment, as Figures 1-4As shown, the alignment confirmation part includes a guiding waist-shaped groove 210 provided on the outer wall of the guiding waist-shaped plate 200 and an alignment confirmation groove 220 provided on the side wall of the guiding waist-shaped groove 210. The alignment confirmation groove 220 is located on a side wall of the guiding waist-shaped groove 210 away from the edge of the guiding waist-shaped plate 200, and the inner surface of the alignment confirmation groove 220 has a pressure sensing sheet electrically connected to the belt conveying component 100; the alignment acting part includes an elastic telescopic rod 440 and an acting roller 450 provided at the end of the elastic telescopic rod 440. The elastic telescopic rod 440 is fixedly connected to the side part of the lower sliding seat 420. The acting roller 450 is fixed to the telescopic end of the elastic telescopic rod 440. The acting roller 450 is inserted into the guiding waist-shaped groove 210 and rolls along the guiding waist-shaped groove 210. In an embodiment of the present invention, the lower sliding seat 420 moves along the outer edge of the guiding waist-shaped plate 200 under the action of the belt conveying component 100. The elastic telescopic rod 440 moves with the lower sliding seat 420 and the acting roller 450 moves with the elastic telescopic rod 440. The acting roller 450 rolls inside the guiding waist-shaped groove 210. When the acting roller 450 moves to the alignment confirmation groove 220, the elastic telescopic rod 440 extends under the action of its own elastic force, and the acting roller 450 rolls into the alignment confirmation groove 220. The alignment confirmation groove 220 plays a certain damping role in the movement of the acting roller 450. At the same time, the pressure sensing sheet in the alignment confirmation groove 220 bears the pressure from the acting roller 450, and the pressure sensing sheet controls the belt conveying component 100 to stop working, so that the lower sliding seat 420 stops moving and stays in the shaft-passing area.

[0037] In one embodiment, as Figures 1-5As shown, the V-shaped pressing member 500 includes a V-shaped downward pressing portion 510, a rotating support arm 530, and an air injection portion 540. The V-shaped downward pressing portion 510 is provided at the telescopic end of the rubber roller pressing cylinder 310. Both side edges of the V-shaped downward pressing portion 510 and the V-shaped supporting portion 410 have side edge portions. The middle of the rotating support arm 530 is rotatably provided at the end of the V-shaped downward pressing portion 510 away from the mandrel pushing mechanism 600 through a tail support 520. The air injection portion 540 is provided at one end of the connecting rod 430. The air injection portion 540 is used to abut against the end of the rubber roller 900 and inject air into the rubber roller 900. An automatic upper part is further provided on the V-shaped downward pressing portion 510. One end of the automatic upper part passes through the edge portion of the V-shaped downward pressing portion 510 and the other end is connected to the end of the rotating support arm 530 away from the air injection portion 540. In the embodiment of the present invention, when the rubber roller pressing cylinder 310 works and pushes the V-shaped downward pressing portion 510 to approach the V-shaped bracket member 400, the movable top rod member 570 gradually approaches the edge portion of the V-shaped supporting portion 410 until it abuts thereon. When the V-shaped downward pressing portion 510 is engaged with the V-shaped supporting portion 410 and clamps the rubber roller 900, the movable top rod member 570 moves upward relative to the V-shaped downward pressing portion 510. The movable top rod member 570 acts on the rotating support arm 530 and causes the rotating support arm 530 to rotate around its connection with the tail support 520. The air injection portion 540 rotates downward and rotates to the end of the rubber roller 900. At this time, the air injection portion 540 covers the end of the rubber roller 900 and can inject air into the rubber roller 900. When the V-shaped downward pressing portion 510 moves upward, the edge portion of the V-shaped supporting portion 410 no longer acts on the automatic upper part, and the automatic upper part can be reset so that the rotating support arm 530 rotates back, so that the air injection portion 540 rotates upward and moves back to the initial position.

[0038] In one embodiment, as Figures 1-5As shown, the automatic upper part includes a front rod member 550 and at least one movable top rod member 570. The front rod member 550 is connected to the end of the rotating support arm 530 away from the gas injection part 540, and a slidable sliding sleeve part 560 is arranged on the front rod member 550; the movable top rod member 570 can slide through the edge part of the V-shaped pressing part 510, and the top of the movable top rod member 570 has an upper connecting plate 590. The upper connecting plate 590 is rotationally matched with the side wall of the sliding sleeve part 560 through a rotating seat; the upper connecting plate 590 is connected to the edge part of the V-shaped pressing part 510 through a reset spring member 580; in the embodiment of the present invention, in the initial state, due to the elastic force of the reset spring member 580, the lower end part of the movable top rod member 570 extends to the lower side of the edge part of the V-shaped pressing part 510, and the front rod member 550 and the rotating support arm 530 are in a horizontal state; when the V-shaped pressing part 510 moves downward and the lower end part of the movable top rod member 570 contacts the edge part of the V-shaped supporting part 410, as the V-shaped pressing part 510 moves downward, the edge part of the V-shaped supporting part 410 can push the movable top rod member 570 to move upward relative to the V-shaped pressing part 510, and the upper connecting plate 590 acts on the sliding sleeve part 560 to make the front rod member 550 rotate upward, so that the rotating support arm 530 rotates and the gas injection part 540 gradually rotates to the end of the rubber roller 900; when the V-shaped pressing part 510 moves away from the V-shaped supporting part 410, under the elastic force of the reset spring member 580, the front rod member 550 and the movable top rod member 570 gradually return to the initial position, and the gas injection part 540 returns to the initial position under the rotation action of the rotating support arm 530.

[0039] In one embodiment, as Figure 1 、 Figure 6 and Figure 7As shown, the shaft-passing material pushing component 650 includes a material pushing lead screw 651, a guide rod 652, a pushing frame part 653 and a material pushing ejector rod 655. The material pushing lead screw 651 and the guide rod 652 are arranged on the shaft-passing frame body 300, and the axial directions of both the material pushing lead screw 651 and the guide rod 652 are consistent with the length direction of the V-shaped feeding part 630. The material pushing lead screw 651 is rotatably connected to the shaft-passing frame body 300, and one end of the material pushing lead screw 651 is connected with a material pushing motor 654. One end of the pushing frame part 653 is connected to both the guide rod 652 and the material pushing lead screw 651. The pushing frame part 653 is slidable between the pushing frame parts 653 and is in screw fit with the material pushing lead screw 651. The other end of the pushing frame part 653 extends to the inside of the V-shaped feeding part 630 and is provided with a material pushing ejector rod 655. In the embodiment of the present invention, when the material pushing motor 654 works and drives the material pushing lead screw 651 to rotate, the material pushing lead screw 651 can act on the pushing frame part 653 through the screw fit with the pushing frame part 653. The pushing frame part 653 moves along the length direction of the V-shaped feeding part 630 under the guiding and restricting of the guide rod 652, so that the material pushing ejector rod 655 follows the pushing frame part 653 to move and push the mandrel 800 from the end, so that the mandrel 800 passes through the glue coating assembly 700 and is inserted into the rubber roller 900. When the mandrel 800 is completely inserted into the rubber roller 900, the material pushing motor 654 drives the material pushing lead screw 651 to turn over. When the material pushing ejector rod 655 moves back and the material pushing ejector rod 655 returns to the initial position, the mandrel 800 at the forefront on the inclined feeding table 620 automatically rolls into the inside of the V-shaped feeding part 630.

[0040] In one embodiment, as Figure 1 、 Figure 6 and Figure 7 shown, centering side rods 640 are arranged on both sides of the inclined feeding table 620. The end of the centering side rod 640 close to the V-shaped feeding part 630 is connected to the side wall of the inclined feeding table 620, and the other end of the centering side rod 640 extends to the side away from the inclined feeding table 620. In the embodiment of the present invention, the distance between the two centering side rods 640 gradually decreases from the inclined feeding table 620 to the V-shaped feeding part 630. Thus, when the mandrel 800 rolls on the inclined feeding table 620, the two centering side rods 640 gradually act on the end of the mandrel 800 and move it to the middle position of the inclined feeding table 620 to achieve automatic centering, which can ensure that each mandrel 800 is in the same position when it rolls into the inside of the V-shaped feeding part 630.

[0041] In one embodiment, as Figure 1 、 Figure 6 、 Figure 7 and Figure 8As shown, a self-blocking component 660 is further provided at the bottom of the V-shaped feeding part 630. The self-blocking component 660 includes a bearing pressure plate strip 661 arranged inside the V-shaped feeding part 630, a driving rotating shaft 663 arranged at the lower end of the V-shaped feeding part 630, and at least one blocking rod 662 that slides through the inclined feeding table 620; a bearing pressure rack 665 that penetrates the bottom wall of the V-shaped feeding part 630 is arranged at the lower end of the bearing pressure plate strip 661. The driving rotating shaft 663 is rotatably connected to the bottom wall of the V-shaped feeding part 630, and a driving gear part 664 that meshes with the bearing pressure rack 665 is provided on the driving rotating shaft 663; the top of the blocking rod 662 extends to the upper side of the inclined feeding table 620, and a lower reset plate 667 is provided at the bottom of the blocking rod 662; the lower reset plate 667 is connected to the bottom of the inclined feeding table 620 through a relief spring 668, and a blocking rack 666 that meshes with the driving gear part 664 is further provided on the side of the blocking rod 662; in the embodiment of the present invention, when the mandrel 800 rolls from the inclined feeding table 620 into the V-shaped feeding part 630, the mandrel 800 presses on the bearing pressure plate strip 661 and the bearing pressure plate strip 661 moves downward. The bearing pressure rack 665 moves downward with the bearing pressure plate strip 661 and meshes with the driving gear part 664 to make the driving rotating shaft 663 rotate. The driving rotating shaft 663 makes the blocking rod 662 move upward through the meshing of the driving gear part 664 and the blocking rack 666. Thus, the top of the blocking rod 662 extends upward and is located on the upper side of the inclined feeding table 620. The end of the blocking rod 662 extending to the upper side of the inclined feeding table 620 can limit the next mandrel 800 from rolling into the V-shaped feeding part 630, thereby avoiding affecting the shaft-passing action of the mandrel 800 in the V-shaped feeding part 630; due to the elastic force of the relief spring 668, the bearing pressure plate strip 661 always has a tendency to move upward and abuts against the arc bottom of the mandrel 800, which can reduce the pressure on the circumferential surface of the mandrel 800 and the inner wall of the V-shaped feeding part 630, and further reduce the resistance when the mandrel 800 passes through the shaft; when the mandrel 800 completes the shaft-passing action and disengages from the V-shaped feeding part 630, under the elastic force of the relief spring 668, the blocking rod 662 moves downward. The blocking rod 662 makes the bearing pressure plate strip 661 move upward through the meshing of the blocking rack 666, the driving gear part 664, and the bearing pressure rack 665. And the top of the blocking rod 662 is flush with the inclined feeding table 620, no longer blocking the mandrel 800, and the mandrel 800 can automatically roll into the V-shaped feeding part 630 to realize automatic feeding.

[0042] In one embodiment, as Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, the glue - applying assembly 700 includes a material storage tank 710, a rotating part 720, a hollow glue - applying ring 730, and a fixed support arm 750. The material storage tank 710 is arranged on the side of the shaft - passing main frame 610 and stores glue inside. The fixed support arm 750 is fixed on the shaft - passing main frame 610, and one end of it extends towards the V - type loading part 630 and the belt conveying component 100. The fixed ring 760 is arranged on the fixed support arm 750 and corresponds to the V - type loading part 630. The rotating part 720 is rotatably arranged inside the fixed ring 760, and a gear ring 721 is provided on the outer wall of the rotating part 720. The hollow glue - applying ring 730 is fixed at the end of the rotating part 720, and a plurality of glue - applying nozzles 740 are provided on the inner wall of the rotating part 720. The outer wall of the hollow glue - applying ring 730 is connected to the material storage tank 710 through a glue - guiding pipe 780. A glue - applying motor 770 is also arranged on the fixed support arm 750, and a glue - applying gear 790 meshing with the gear ring 721 is provided at the output end of the glue - applying motor 770. In the embodiment of the present invention, when the mandrel 800 passes through the inside of the rotating part 720 and the hollow glue - applying ring 730, the glue in the material storage tank 710 enters the inside of the hollow glue - applying ring 730 through the glue - guiding pipe 780 and is sprayed onto the circumferential surface of the mandrel 800 by the glue - applying nozzles 740. At the same time, the glue - applying motor 770 works and drives the rotating part 720 to rotate forward and backward alternately through the glue - applying gear 790. Therefore, the hollow glue - applying ring 730 rotates forward and backward alternately, and the circumferential surface of the mandrel 800 can be comprehensively coated with glue by using a plurality of glue - applying nozzles 740. Furthermore, after the shaft - passing, the bonding strength between the mandrel 800 and the rubber roller 900 is increased.

[0043] The above embodiments provide a shaft-passing device for processing a printer rubber roller. Among them, when the belt conveying component 100 works and enables a plurality of V-shaped bracket components 400 to reciprocate and move in a circular motion along the outer edge of the guiding oval plate 200, the rubber roller 900 moves along with the V-shaped bracket component 400; when the V-shaped bracket component 400 moves to the shaft-passing area (i.e., directly below the V-shaped pressing component 500), the alignment confirmation part can damp the movement of the V-shaped bracket component 400 and control the power source of the belt conveying component 100 to stop. At this time, the belt conveying component 100 stops working and the V-shaped bracket component 400 no longer moves, and the V-shaped bracket component 400 is directly below the V-shaped pressing component 500; the rubber roller pressing cylinder 310 works and drives the V-shaped pressing component 500 to move downward. The V-shaped pressing component 500 cooperates with the V-shaped bracket component 400 to clamp the rubber roller 900, and one end of the V-shaped pressing component 500 acts on the end of the rubber roller 900 away from the mandrel pushing mechanism 600 and blows an expanding air flow into it; the rubber roller 900 begins to expand; the mandrel 800 is on the inclined feeding table 620 and the inclined feeding table 620 is in an inclined state. The foremost mandrel 800 automatically rolls into the V-shaped feeding part 630. At this time, the V-shaped feeding part 630 is in an aligned state with the V-shaped bracket component 400 in the shaft-passing area, and the mandrel 800 and the rubber roller 900 respectively located in the two are coaxial; the shaft-passing pushing component 650 and the glue coating assembly 700 start to work. The shaft-passing pushing component 650 starts to push the mandrel 800 from one end so that the mandrel 800 moves towards the rubber roller 900. The mandrel 800 passes through the glue coating assembly 700 and the glue coating assembly 700 rotates to coat a part of the circumferential surface of the mandrel 800 located inside it; the glue-coated mandrel 800 can be correspondingly inserted into the rubber roller 900. Since the rubber roller 900 expands under the action of the V-shaped pressing component 500, the resistance of the mandrel 800 inserted into the rubber roller 900 is relatively small, and the axial movement of the rubber roller 900 can be avoided; after the mandrel 800 is completely inserted into the rubber roller 900, the V-shaped pressing component 500 stops blowing air into the rubber roller 900; the rubber roller 900 contracts and completes the bonding with the circumferential surface of the mandrel 800; after the shaft-passing is completed, the shaft-passing pushing component 650 returns to its original position, the foremost mandrel 800 on the inclined feeding table 620 automatically rolls into the V-shaped feeding part 630, the rubber roller pressing cylinder 310 works and drives the V-shaped pressing component 500 away from the V-shaped bracket component 400. At the same time, the belt conveying component 100 continues to work and moves the next V-shaped bracket component 400 to the shaft-passing area to facilitate the next set of shaft-passing actions, thereby realizing automatic shaft-passing work and effectively improving work efficiency; the setting of the alignment confirmation part can achieve automatic positioning in the horizontal direction and ensure that the mandrel 800 is accurately inserted into the rubber roller 900.
