Description

Technical Field

[0001] The invention relates to the technical field of glass production and processing, and in particular to a paper supporting mechanism and a paper laying machine. Background Art

[0002] At present, in glass production, a piece of spacer paper is added between the glass sheets when they are stacked to prevent the surface from being scratched during storage and transportation. Since the glass sheets are continuously transported out of the annealing kiln, the paper laying work must be done online, that is, the spacer paper is laid on the glass surface during the movement of the glass.

[0003] Among them, the laying of the spacer paper is generally done with the help of a paper laying machine, and the paper laying machine needs to use a guide rod to change the conveying direction of the spacer paper in the process of driving the spacer paper to move, so that the spacer paper supplied by the paper roller bypasses the guide rod and is clamped by two driving rollers, and then the spacer paper is driven to move in the supply direction through the rotation of the driving roller. The traditional guide rod is rotatably set on the paper laying machine. When the paper roller needs to be replaced, this design method requires the use of external equipment to re-circulate the spacer paper around the guide rod, which is complicated to operate; and in order to tighten the spacer paper, the driving speed of the driving roller is generally greater than the spacer paper supply speed of the paper roller, and the traditional guide rod will not move according to its own force conditions, which makes it easy for the spacer paper to break, wasting material costs and affecting work efficiency. Summary of the invention

After the spacer paper is clamped between the two driving rollers, the driving component drives the swing arm sleeve to swing, so that the end of the swing arm sleeve close to the paper supporting rod is tilted downward, so that the paper supporting rod and the swing rod move towards the direction of the spacer paper under the action of their own gravity, until the paper supporting rod is supported on the side of the spacer paper, thereby tightening the spacer paper to ensure the transmission effect of the spacer paper.

[0028] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0029] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the implementation methods in the specification are only part of the implementation methods of the present invention, rather than all of the implementation methods.

[0030] Combination Figures 1 to 3 As shown, the paper supporting mechanism provided by the embodiment of the present invention includes a paper supporting rod 1, a swinging assembly and a driving assembly.

[0031] like Figure 1As shown, the outer periphery of the paper support rod 1 is connected to a swing rod 2, and the paper support rod 1 is used to support one side of the spacer paper 91 to play the role of tensioning the spacer paper 91. The swing rod 2 is preferably perpendicular to the paper support rod 1, and the swing rod 2 has a certain length to facilitate the connection between the swing rod 2 and the swing assembly. Figure 2 and Figure 3 As shown, the swing assembly includes a support seat 3 and a swing arm sleeve 4 hingedly arranged on the support seat 3 in the horizontal direction, and the end of the swing arm 2 away from the paper support rod 1 is inserted into the swing arm sleeve 4 and slidably cooperates with the swing arm sleeve 4. Specifically, the support seat 3 and the paper support rod 1 are spaced apart, and the distance between the support seat 3 and the paper support rod 1 should meet the design requirements to prevent the support seat 3 from affecting the transmission of the spacer paper 91. The horizontal hinge here means that the hinge axis of the support seat 3 and the swing arm sleeve 4 is arranged in the horizontal direction, and the hinge axis is parallel to the paper support rod 1, and then the swing arm 2 and the paper support rod 1 can be driven to swing by the swing of the swing arm sleeve 4. Under normal conditions, the paper support rod 1 is supported on the side of the spacer paper 91 or on the ground under the action of gravity. At this time, the end of the swing arm sleeve 4 close to the paper support rod 1 is tilted downward, and the tilt angle of the swing arm sleeve 4 is consistent with the tilt angle of the swing arm 2, and in this state, the swing arm 2 will not be separated from the swing arm sleeve 4. The driving assembly is used to drive the swing arm sleeve 4 to swing around the hinge position (the hinge axis) between the swing arm sleeve 4 and the support seat 3 to change the angle between the axis of the swing arm sleeve 4 and the horizontal direction, specifically, to make the end of the swing arm sleeve 4 close to the paper support rod 1 tilt upward. In this state, the tilt angle of the swing rod 2 is consistent with the tilt angle of the swing arm sleeve 4, and then the paper support rod 1 is lifted up by the swing rod 2. At this time, the paper support rod 1 and the swing rod 2 will slide toward the swing arm sleeve 4 under the action of their own gravity, so that the paper support rod 1 is separated from the spacer paper 91.

[0032] The paper supporting mechanism provided by the present invention comprises a movably arranged paper supporting rod 1, such as Figure 4 As shown, when the paper roller 9 is replaced, the swing arm sleeve 4 is driven by the driving component to swing, so that the end of the swing arm sleeve 4 close to the paper supporting rod 1 is tilted upward, so that the paper supporting rod 1 and the swing rod 2 slide in the direction away from the paper roller 9 under the action of their own gravity, so as to avoid the natural fall of the spacing paper 91 on the paper roller 9. After the spacing paper 91 is clamped between the two driving rollers 10, the driving component drives the swing arm sleeve 4 to swing, so that the end of the swing arm sleeve 4 close to the paper supporting rod 1 is tilted downward, so that the paper supporting rod 1 and the swing rod 2 are moved toward the spacing paper under the action of their own gravity. 91 until the paper supporting rod 1 is supported on the side of the spacer paper 91, thereby tightening the spacer paper 91 to ensure the transmission effect of the spacer paper 91. When replacing the paper roller 9, the paper supporting mechanism of this design does not need to rely on external equipment, which reduces equipment cost and increases the convenience of replacement. The spacer paper 91 is supported by the gravity of the paper supporting rod 1 and the swing rod 2. When the driving force of the spacer paper 91 is too large, the spacer paper 91 can push the paper supporting rod 1 to move, thereby avoiding the phenomenon of the spacer paper 91 breaking, saving material cost and ensuring work efficiency.

[0033] Combination Figures 1 to 3 The support seat 3 includes a frame 31, and the swing arm sleeve 4 is hingedly arranged inside the frame 31. Specifically, the frame 31 is a square frame, and a bottom plate is provided at the bottom of the square frame to support the square frame. The swing arm sleeve 4 is rectangular, and a cylindrical through hole is formed inside the swing arm sleeve 4, and the diameter of the through hole matches the diameter of the swing rod 2 for the swing rod 2 to be inserted. The corresponding two sides of the swing arm sleeve 4 are respectively hinged to the inner wall of the square frame corresponding thereto. Preferably, the swing arm sleeve 4 is connected to the side wall of the square frame through a bearing. Specifically, the side wall of the square frame is provided with a bearing, and the bearing is installed on the side wall of the square frame through a bearing seat 32. A rotating shaft is provided on the side of the swing arm sleeve 4, and the rotating shaft is connected to the inner ring of the bearing, thereby realizing the hinged installation of the swing arm sleeve 4.

[0034] like Figure 3 As shown, linear bearings 41 are respectively provided at both ends of the swing arm sleeve 4, and the swing rod 2 slides with the linear bearings 41. The linear bearings 41 are conventional technologies, so their structure is not described in detail. The swing rod 2 passes through the linear bearings 41, so that the sliding friction between the swing rod 2 and the swing arm sleeve 4 is converted into rolling friction, ensuring the smooth movement of the swing rod 2.

[0035] like Figure 1 As shown, there are multiple rocker arms 2, which are spaced apart along the length direction of the paper supporting rod 1, and each rocker arm 2 is connected with a swing assembly and a driving assembly. When in use, the two rocker arms 2 are driven simultaneously, thereby driving the paper supporting rod 1 to swing, thereby increasing the stability of the movement of the paper supporting rod 1.

[0036] The swing arm 2 is provided with a limit block 21, and the limit block 21 is configured to be installed at any position of the swing arm 2. By setting the limit block 21, when the end of the swing arm sleeve 4 close to the paper support rod 1 is tilted upward, the distance of movement of the paper support rod 1 can be limited by the contact between the limit block 21 and the end of the swing arm sleeve 4 during the movement of the paper support rod 1 toward the swing arm sleeve 4, so as to avoid the excessive stroke of the paper support rod 1, which affects the normal operation of the paper laying machine. And the position of the limit block 21 is adjustable, so that the stroke of the paper support rod 1 can be selectively adjusted. Among them, there are many ways to adjust the limit block 21, for example, the limit block 21 is sleeved on the outer periphery of the swing arm 2, and a screw hole is opened on one side of the limit block 21, and the screw rod is screwed so that the end of the screw rod is pressed against the outer periphery of the swing arm 2 to complete the fixing of the limit block 21. For another example, the limit block 21 can be a clamp, which is sleeved on the outer periphery of the swing arm 2, and the clamp is opened or fixed by screwing the bolt of the clamp. It can be seen that the specific configuration of the limit block 21 is not limited, as long as it can meet the limit requirements and the adjustability requirements.

[0037] Combination Figure 2 and Figure 3As shown, the driving assembly includes a vertically arranged telescopic rod 5 and a driving cylinder 51 for driving the telescopic rod 5 to move along its length direction, the driving rod is arranged on the support seat 3, the end of the telescopic rod 5 is movably connected to the swing arm sleeve 4, and the hinge position of the swing arm sleeve 4 and the support seat 3 is located on the side of the connection position of the telescopic rod 5 and the swing arm sleeve 4 close to the paper support rod 1. Specifically, when the support seat 3 includes a square-shaped frame 31, the driving cylinder 51 is arranged at the top of the frame 31, and the telescopic rod 5 extends downward to the inside of the frame 31, and the telescopic rod 5 is driven by the driving cylinder 51 to move in the vertical direction, so that the telescopic rod 5 drives the end of the swing arm sleeve 4 away from the paper support rod 1 to move in the vertical direction, so that the swing arm sleeve 4 swings around the hinge axis. And the setting mode of the movably connected end of the telescopic rod 5 and the swing arm sleeve 4 enables the telescopic rod 5 to adapt to the changes in the angle and position of the swing arm sleeve 4, avoiding the phenomenon that the swing arm sleeve 4 cannot swing due to mutual locking. The driving assembly includes a cylinder, a hydraulic cylinder or an electric push rod. Preferably, the driving assembly includes a cylinder. In this case, the driving cylinder 51 is the cylinder body of the cylinder, and the telescopic rod 5 is the lever of the cylinder. Further optimized, the bottom end of the telescopic rod 5 is connected to the guide rod 7 through a connecting sleeve 8, which increases the convenience of connecting the telescopic rod 5 and the guide rod 7. The connecting sleeve 8 is a conventional technology, so its structure is not described in detail here.

[0038] In some embodiments, a hanging ear 6 is provided at the top of the swing arm sleeve 4, and a strip hole 61 is formed on the hanging ear 6. A guide rod 7 is provided at the end of the telescopic rod 5 and is slidably arranged in the strip hole 61. The extension direction of the guide rod 7 is perpendicular to the axial direction of the swing arm sleeve 4, so that the guide rod 7 can slide along the length direction of the strip hole 61. Specifically, Figure 3 As shown, the end of the strip hole 61 away from the paper support rod 1 is tilted upward relative to the swing arm sleeve 4, and the guide rod 7 is at the end of the strip hole 61 away from the paper support rod 1 in a normal state. The normal state here refers to the state when the driving component is not working, that is, the paper support rod 1 is against the side of the spacer paper 91, or the paper support rod 1 is supported on the bottom surface.

[0039] The working principle of the paper supporting mechanism of the present invention is as follows:

[0040] like Figure 4As shown, under normal conditions, the paper support rod 1 is supported on the side of the spacer paper 91. When the paper roller 9 is replaced, the cylinder drives the telescopic rod 5 to extend (the telescopic rod 5 moves downward). At this time, the guide rod 7 pushes the hanging ear 6 and the swing arm sleeve 4 to swing in the clockwise direction around the hinge axis. At this time, the guide rod 7 slides in the strip hole 61 to adapt to the change in the angle of the swing arm sleeve 4. The swing of the swing arm sleeve 4 drives the swing rod 2 to swing, and then the paper support rod 1 is lifted by the swing rod 2 until the end of the swing arm sleeve 4 close to the paper support rod 1 tilts upward. Under the action of their own weight, the paper support rod 1 and the swing rod 2 overcome the rolling friction between the swing rod 2 and the linear bearing 41, so that the paper support rod 1 moves toward the swing arm sleeve 4 until the limit block 21 contacts the end of the swing arm sleeve 4 or the linear bearing 41. In this position, the paper support rod 1, that is, the swing rod 2, will not affect the vertical efficiency of the spacer paper 91, and the end of the spacer paper 91 is clamped between the two driving rollers 10. After the roller replacement is completed, the cylinder drives the telescopic rod 5 to retract (the telescopic rod 5 moves upward). At this time, the telescopic rod 5 drives the swing arm sleeve 4 to rotate in the counterclockwise direction. At this time, the guide rod 7 slides in the strip hole 61 to adapt to the change in the angle of the swing arm sleeve 4. The swing of the swing arm sleeve 4 drives the swing rod 2 to swing. Under the action of their own weight, the swing rod 2 and the paper support rod 1 overcome the rolling friction of the linear bearing 41 and move toward the direction of the spacer paper 91. The paper support rod 1 supports the side of the spacer paper 91 and spreads the support surface for a distance, thereby tightening the spacer paper 91. During use, when the driving roller 10 clamps the spacer paper 91 and transmits the spacer paper 91 with the cooperation of the paper roller 9, in order to tighten the paper, the paper feeding speed of the paper roller 9 will be slightly lower than the paper feeding speed of the driving roller 10. At this time, the spacer paper 91 will push the paper support rod 1 and the swing rod 2 to overcome their own weight and the friction with the linear bearing 41 and move toward the swing arm sleeve 4. When the spacer paper 91 is used to push the paper support rod 1 and the swing rod 2 to move, the required thrust should not be so large as to damage the spacer paper 91, so as to avoid the breakage of the spacer paper 91. When the paper feeding movement of the driving roller 10 stops, the paper laying machine will continue to work. At this time, the paper support rod 1 and the swing rod 2 move in a direction away from the swing arm sleeve 4 under the action of their own weight and the driving force of the cylinder until the swing rod 2 contacts the induction switch, and the paper laying machine as a whole stops working.
