[0020] The first guide mechanism includes two first slider rails 6, a slide plate 11 and a mounting plate 10 which are sequentially arranged from bottom to top; wherein the two first slider rails 6 are fixed on the bottom plate 701 in a side-by-side manner along the front-to-back direction of the bottom frame 7; the slide plate 11 is horizontally fixed on the sliders of the two first slider rails 6, so that the slide plate 11 can slide back and forth in the front-to-back direction of the bottom frame 7 through the two first slider rails 6; bearing seats 3 are symmetrically fixed on the left and right sides of the slide plate 11, and a rotating shaft 14 is horizontally arranged above the slide plate 11, and its two ends are assembled in the two bearing seats 3 through rotating bearings, so that the rotating shaft 14 can rotate freely on the slide plate 11; the mounting plate 10 Two rear connecting plates 1001 are symmetrically and vertically fixed on the bottom surface of the rear end, and shaft holes matching the rotating shaft 14 are opened on the plate bodies of the two plates, so that the rear end of the mounting plate 10 passes through the two rear connecting plates 1001 and is fixed on the rotating shaft 14, so that the mounting plate 10 can be flipped and rotated relative to the slide plate 11; two front connecting plates 1002 are symmetrically and vertically fixed on the bottom surface of the front side of the mounting plate 10, and mounting shafts are passed through the plate bodies of the two plates, and hanging bearings 13 are sleeved on the outer ends of the mounting shafts, so that the mounting plate 10 is respectively embedded in the guide grooves 201 of the two guide plates 2 through the two hanging bearings 13 on the front side, and forms a movable connection with the guide frame.

[0021] As a preferred technical solution of this embodiment, a supporting vertical plate 702 is arranged on the top surface of the front end of the bottom plate 701, which is arranged along the left and right directions of the base frame 7 and vertically fixed on the bottom plate 701; the height of the supporting vertical plate 702 is adapted to the setting height of the mounting plate 10, so that when the mounting plate 10 is set in a horizontal state, its bottom surface is just pressed onto the top surface of the supporting vertical plate 702; in addition, the two ends of the supporting vertical plate 702 are vertically fixed on the two guide plates 2 to increase the structural strength of the connection between the guide frame and the base frame 7.

[0022] The first conveying mechanism includes two first cylinders 4, which are symmetrically arranged on both sides above the mounting plate 10 along the front-to-back direction of the base frame 7. Correspondingly, two front articulated seats 401 are symmetrically fixed on the top surface of the front end of the mounting plate 10, and two rear articulated seats 402 are symmetrically fixed on the top surface of the rear end of the base plate 701; the cylinder ends of the two first cylinders 4 are respectively hingedly connected to the two rear articulated seats 402, and the movable push rod ends of the two are respectively hingedly connected to the two front articulated seats 401.

[0023] In actual application, in the initial state, the movable push rods of the two first cylinders 4 are in the retracted state, the mounting plate 10 is arranged in a horizontal state, and the two suspension bearings 13 arranged thereon are respectively located at the rear ends of the guide grooves 201 of the two guide plates 2, that is, at the lowest positions of the guide grooves 201. At this time, the slide plate 11 rotatably connected to the rear end of the mounting plate 10 is located along with the slider at the rear end of the slide rail of the first slider rail 6, that is, at the rear end side of the bottom frame 7; subsequently, when the movable push rods of the two first cylinders 4 are synchronously and gradually extended outwards, the mounting plate 10, on the one hand, is pushed forward by the movable push rods, driving the slide plate 11 and the slider to move forward synchronously, and on the other hand, is driven by the two The movement direction of each suspension bearing 13 in the two guide grooves 201 is limited, and it flips upward around the rotating shaft 14 relative to the slide plate 11; further, under the action of the above two aspects, the mounting plate 10 can move obliquely forward along a predetermined small-angle path until the two suspension bearings 13 on the mounting plate 10 are respectively located at the front ends of the guide grooves 201 of the two guide plates 2, that is, at the highest position of the guide grooves 201; and, since the guide groove 201 is designed as an oblique upward channel with a variable slope, the mounting plate 10 can adjust the inclination angle during the forward movement, so that it can transport the pressure roller installed at the front end to the specified position at a specified angle.

[0024] As a preferred technical solution of this embodiment, a first buffer 5 and a second buffer 12 are further provided on the bottom plate 701; wherein the first buffer 5 is provided on the front side of the bottom plate 701, and is specifically provided on a first buffer mounting plate vertically fixed on the bottom plate 701; specifically, the setting height of the first buffer 5 is adapted to the setting height of the rotating shaft 14, and the collision end is provided toward the rotating shaft 14, so that when the two suspension bearings 13 on the mounting plate 10 move to the rear end of the guide groove 201, the rotating shaft 14 abuts against the collision end of the first buffer 5; the second buffer 12 is provided at the rear end of the bottom plate 701, It is specifically arranged on a second buffer mounting plate which is centered and vertically fixed on the bottom plate 701; the setting height of the second buffer 12 is adapted to the setting height of the skateboard 11, and the collision end is arranged toward the skateboard 11, so that when the two suspension bearings 13 on the mounting plate 10 move to the front end of the guide groove 201, the skateboard 11 abuts against the collision end of the second buffer 12; thereby, the two buffers are used to limit the reciprocating front and rear moving distance of the skateboard 11, and at the same time prevent the skateboard 11 from causing a hard collision when it moves to the front and rear ends; in this embodiment, the first buffer 5 and the second buffer 12 both use spring buffers.

[0025] The second guide mechanism includes a guide conveyor frame 8 and two second slider rails 9; wherein the guide conveyor frame 8 is composed of a connecting frame and a roller mounting frame, the connecting frame includes two connecting beams, which are arranged side by side and spaced apart along the front and rear direction of the base frame 7, so that there is a space for installing the second cylinder 1 in the middle; the roller mounting frame is a U-shaped frame body, which is fixed on the front end face of the two connecting beams with the opening facing forward; a roller mounting shaft 16 is horizontally fixed at the front end of the U-shaped frame body along the left and right direction of the base frame 7, and the size of the U-shaped frame body and the length of the roller mounting shaft 16 meet The invention can be used to assemble rollers 15 of different specifications; in actual application, the roller 15 is centrally sleeved and rotatably mounted on the roller mounting shaft 16; in order to increase the connection strength between the two connecting beams, the rear sides of the two connecting beams are connected and fixed by a spanning arch connector; the two second slider rails 9 are invertedly arranged along the front and rear directions of the base frame 7, and the two slide rails are symmetrically fixed on the bottom surfaces of the two connecting beams, and the two sliders are symmetrically fixed on the top surface of the mounting plate 10, so that the guide conveyor frame 8 can move forward and backward relative to the mounting plate 10 through the two second slider rails 9.

[0026] The second conveying mechanism includes a second cylinder 1, which is arranged along the front-to-back direction of the base frame 7, and its cylinder barrel is centrally arranged between the two connecting beams and fixed on the mounting plate 10, and its movable push rod is arranged forward and vertically fixed on the rear end face of the pressure roller mounting frame; in actual application, the second cylinder 1 drives the guide conveying frame 8 to move forward relative to the mounting plate 10 to realize the continued forward conveyance of the pressure roller to the outside of the mounting plate 10, until the pressure roller 15 is conveyed to a position where it is tightly fitted on the tread.

[0027] As a preferred technical solution of this embodiment, in order to facilitate the replacement of the suspension bearing 13 and subsequent maintenance, a T-shaped notch with an upper opening width greater than a lower opening width is opened on the top surface of the rear end of each guide plate 2. The T-shaped notch is connected to the guide groove 201, and its lower opening width is slightly greater than the diameter of the suspension bearing 13, so that the suspension bearing 13 can be easily and quickly removed and installed through the T-shaped notch during replacement and maintenance; correspondingly, a T-shaped quick-change block 17 is embedded in the T-shaped notch, and its two ends are detachably fixed to the guide plate 2 by two bolts.

[0028] See also Figure 7~Figure 10 The specific working principle of the compact tread roller guide conveying device is described as follows. Figure 7~Figure 10 In the figure, the guide plate 2 is vertically sectioned to show that the guide groove 201 is in the form of a through hole, so as to facilitate description of the fitting relationship between the guide groove 201 and the suspension bearing 13 during the process of the compact tread roller guide conveying device conveying the pressure roller 15 forward.

[0029] See also Figure 1 and Figure 7On the tread rolling process operation platform of the present embodiment, a belt drum A for sleeve-mounting the belt layer and the tread layer is arranged on one side of the platform, and a belt layer transfer ring C is arranged below the belt drum A, which is fixed to the operation platform through a base; a power device D is fixed on the other side of the platform, and a belt bonding beater B is arranged above the power device D, which is hingedly connected to the power device D; based on the current device layout of the tread rolling process platform, the tread pressing roller and its conveying device can only be arranged in the narrow arrangement space formed by the belt layer transfer ring C, the belt bonding beater B and the power device D. In the space, the tread roller is conveyed to a position close to the tread, thereby ensuring the completion of the tread rolling process; as shown in the figure, in addition to the narrow layout space of the tread roller and its conveying device, the conveying path of the tread roller is also limited in space, so the traditional conveying device not only has insufficient installation space, but also its direct oblique upward roller conveying process will inevitably cause it to collide with the belt bonding beater B, causing damage to the equipment; the compact structure of the compact tread roller guide conveying device of the present invention can firstly meet the requirements of device installation in a narrow layout space.

[0030] See also Figure 2 and Figure 8 When the belt layer and the tread layer are successively installed on the belt drum A, the pressure roller 15 needs to be extended to fit with the tread to assist the belt drum A in rolling the tread; at this time, the two first cylinders 4 of the first conveying mechanism synchronously extend the movable push rods outward to move the mounting plate 10 forward and flip it upward from the horizontal setting state to the oblique setting state; in this process, since the two suspension bearings 13 arranged at the front end of the mounting plate 10 are respectively embedded in the guide grooves 201 of the guide plates 2 on both sides, the upward flipping angle of the mounting plate 10 is limited by the position of the guide grooves 201, so that the mounting plate 10 flips upward while moving forward, and extends obliquely forward in a variable curvature manner. Ensure that the guide conveyor frame 8 with the pressure roller 15 will not collide with the belt layer transfer ring C and the belt bonding beat B from beginning to end; specifically, the guide groove 201 is a variable slope channel composed of a first strip groove and a second strip groove, and the angle formed by the first strip groove and the horizontal direction is α, and the angle α is used to control the guide conveyor frame 8 with the pressure roller 15 to always extend outward obliquely with a gap between the upper belt bonding beat B and the lower belt layer transfer ring C, until the two suspension bearings 13 on the mounting plate 10 go up from the rear end of the first strip groove to the front end of the first strip groove, at which time, the mounting plate 10 with the guide conveyor frame 8 reaches the first conveying position.

[0031] See also Figure 4 and Fig. 9, the two suspension bearings 13 on the mounting plate 10 enter the second strip groove and continue to move upward. During this process, the angle between the second strip groove and the horizontal direction is β, and the angle β controls the final oblique flipping angle of the guide conveyor frame 8, that is, when the two suspension bearings 13 on the mounting plate 10 move upward to the front end of the second strip groove, the oblique angle of the guide conveyor frame 8 can make the center point of the pressure roller 15 intersect with the central axis of the belt drum A when it continues to move forward along the oblique direction; furthermore, it is determined that the pressure roller can eventually effectively roll the tread. At this time, the mounting plate 10 provided with the guide conveyor frame 8 arrives at the second conveying position.

[0032] See also Figure 5 , Figure 6 and Fig.10 When the oblique moving direction of the pressure roller 15 is determined, the active push rods of the two first cylinders 4 maintain the current moving stroke state; at this time, the active push rod of the second cylinder 1 continuously extends forward to drive the pressure roller 15 to continue to move forward along the current oblique direction until the outer peripheral surface of the pressure roller 15 is tightly attached to the outer peripheral surface of the tread wound on the belt drum A. At this time, the mounting plate 10 provided with the guide conveyor frame 8 reaches the third conveying position; the active push rod of the second cylinder 1 is kept in the current moving stroke state, so that the pressure roller 15 cooperates with the belt drum A to complete the tread rolling process.

[0033] The compact tread roller guide conveying device also includes a control mechanism, which includes a first displacement sensor, a second displacement sensor and a controller; wherein, There are two first displacement sensors, which are respectively arranged on the two first cylinders 4 to monitor the travel variable of the movable push rod of the first cylinder 4; The second displacement sensor is arranged on the second cylinder 1 to monitor the travel variable of the movable push rod of the second cylinder 1; The controller is electrically connected to the magnetic switch controlling the first cylinder 4 and the two first displacement sensors respectively, so as to drive the two first cylinders 4 to synchronously extend the movable push rods, and determine the moment when the stroke variable of the movable push rod of the first cylinder 4 reaches the specified △S1 through the first displacement sensor; at this moment, the two suspension bearings move to the front end of their guide grooves respectively, and the mounting plate 10 flips upward to reach the maximum tilt angle; The controller is also electrically connected to the magnetic switch for controlling the extension and retraction of the second cylinder 1 and the second displacement sensor, so as to drive the second cylinder 1 to extend the movable push rod when the mounting plate 10 is turned upward to reach the maximum tilt angle, and determine the moment when the stroke variable of the movable push rod of the second cylinder 1 reaches the specified △S2 through the second displacement sensor; at this moment, the roller surface of the pressure roller presses against the tread; When the tread rolling process is completed, the controller first controls the movable push rod of the second cylinder 1 to retract, and the retraction stroke variable is △S2, and then controls the movable push rods of the two first cylinders 4 to retract synchronously, and the retraction stroke variable is △S1; the compact tread roller guide conveying device returns to the initial setting state and waits for the next tread rolling.

[0034] In this embodiment, the controller is disposed in a control box 18 , and the control box 18 is fixed on the outer surface of the guide plate 2 on one side. The control box 18 is fixed on the outer surface of the guide plate 2 on one side through a control pipeline.
