Description

TECHNICAL FIELD

[0001] The utility model relates to paper sheet slitting machine technical field, concretely is a kind of pneumatic pressure tight slitting machine material fixing device. BACKGROUND

[0002] In paper processing, packaging, printing and other industries, paper slitting machine as a kind of key equipment, its function is to cut wide web into various required width and diameter independent paper roll, to meet the needs of different downstream processes. Paper slitting machine is mainly composed of the following several core parts: rack and transmission system, material feeding and winding mechanism, traction component and slitting support and blade. Rack and transmission system provides support and power transmission for the whole equipment, ensures the stable operation of each component. Material feeding and winding mechanism is responsible for the unwinding and winding of roll material, and is one of the core components of slitting machine, usually including synchronous wheel, magnetic powder clutch, compression roller, gas inflation shaft and other components. After roll material is fixed on gas inflation shaft, it is fixed by compression roller to ensure the smooth progress of slitting process. Traction component is responsible for conveying paper to the slitting position at a constant speed, while slitting support and blade perform the actual cutting action.

[0003] The existing compression roller is usually manually buckled on the roll material through the linkage support, and the self-weight is used to realize the compression and fixation of the roll material. The significant disadvantage of this method is that the pressure applied to the roll material is unstable and uncontrollable. In the initial stage of thick roll material, although the compression roller can keep in contact with the surface of the roll material, due to the limited self-weight, the pressure applied is small, which may cause the roll material to be not fixed firmly, and sliding or displacement occurs during the slitting process, affecting the slitting precision and quality. As the roll material is continuously used, its thickness gradually decreases, and the compression roller naturally drops under the action of self-weight, at this time, the pressure applied to the roll material increases. This increase in pressure easily causes the edge of the roll material to be warped, especially for some thin or easily deformed paper materials, the edge warping problem is particularly prominent.

[0004] In addition, the existing manual buckling method is complicated and inefficient, and needs close operation by artificial, which has certain safety hazards. Moreover, since the pressure is not adjustable, it is difficult to adapt to roll materials of different thickness and different material, which limits the application range and flexibility of the slitting machine. Therefore, how to provide a roll material fixing device capable of automatically adjusting pressure, adapting to different roll material characteristics, convenient to operate and safe and reliable, has become a problem to be solved in the technical field of paper slitting machine. UTILITY MODEL CONTENTS

[0005] In view of the shortcomings of the prior art, the utility model provides a pneumatic pressure tight slitting machine material fixing device, which solves the problems of edge warping of paper caused by the compression roller of the existing slitting machine and inconvenient manual control.

[0006] In order to realize the above-mentioned purpose, the utility model discloses a kind of pneumatic pressure tight slitting machine material fixing device, including being set on the air expansion shaft and compression roller of slitting machine;Further including:

[0007] Frame body, can be driven to make the compression roller close or away from air expansion shaft along first direction by swing cylinder;

[0008] Second pressure cylinder, be set on the frame body, drive the compression roller close or away from air expansion shaft along second direction;

[0010] Preferably, the frame body includes base, the base is hinged with inclined beam arm, the inclined beam arm top is fixed with crossbeam arm, and the crossbeam arm is arranged along the axial direction of the compression roller.

[0011] Preferably, the two ends of the swing cylinder are hinged on base and inclined beam arm respectively.

[0012] Preferably, the output end of the second pressure cylinder is arranged obliquely downward.

[0013] Preferably, the output end of the second pressure cylinder is provided with shaft seat, and the compression roller is arranged on the shaft seat.

[0014] Preferably, the displacement mechanism includes:

[0015] Base, base is arranged on base;

[0016] Displacement cylinder, be set on the base, drive base to move on the base.

[0017] Preferably, the displacement mechanism further includes:

[0018] Connecting table, be set below the base;

[0019] Inclined surface, form in the lower surface of the connecting table and the upper surface of the base;The front end of the displacement cylinder is hinged on the base.

[0020] Preferably, the inclined direction of the inclined surface is gradually inclined downward along third direction, so that the connecting table below the base is inclined and moves upward or downward.

[0021] Preferably, the bottom of the connecting table is provided with boss, and the top surface of the base is provided with guide groove matched with the boss.

[0022] Preferably, the first direction is the swing direction of inclined beam arm swinging around the hinged end with base;The second direction is the output direction of second pressure cylinder;The third direction is the moving direction of base on base.

[0023] The beneficial effects of this utility model are as follows: By using the material fixing device of the pneumatic pressing and slitting machine provided by this utility model, the displacement mechanism drives the frame and the pressure roller to approach or move away from the air expansion shaft along the third direction, which can provide sufficient space for the air expansion shaft during the feeding stage. The roll material can be easily set on the air expansion shaft, avoiding the feeding difficulties caused by the fixed position of the pressure roller in the prior art, making the feeding process easier and more convenient.

[0024] The slitting machine achieves a large stroke displacement by driving the frame and pressure rollers with a swing cylinder, allowing the pressure rollers to quickly approach and move away from the roll material and apply primary pressure. This initially fixes the roll material on the air shaft, effectively preventing initial slippage during the slitting process and improving slitting accuracy. Simultaneously, the large stroke displacement design allows the pressure rollers to adapt to roll materials of different diameters, expanding the slitting machine's applicability.

[0025] The secondary pressure cylinder is used to drive the pressure roller to approach or move away from the air expansion shaft along the second direction to apply secondary pressure to the roll material. This can significantly increase the pressing pressure on the roll paper, effectively solve the edge warping problem caused by traditional single-stage pressing, and ensure that the roll material remains in a stable and fixed state throughout the entire slitting process, avoiding various problems caused by excessive or insufficient pressure.

[0026] Meanwhile, the movement in three directions allows the frame that houses the pressure rollers to be used within a relatively small space inside the slitting machine, which not only saves space but also reduces the manufacturing cost of the equipment. Attached Figure Description

[0034] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0036] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0037] like Figures 1 to 5 As shown in the embodiment of this application, a material fixing device for a pneumatic pressing slitting machine is proposed, including an air shaft 1 and a pressure roller 2 mounted on the slitting machine. It also includes a frame, a secondary pressure cylinder 8, and a displacement mechanism.

[0038] In this embodiment, the secondary pressure cylinder 8 is mounted on the frame. During the feeding stage, the displacement mechanism drives the frame and pressure roller 2 away from the air expansion shaft 1 along the third direction; after feeding, the displacement mechanism drives the frame and pressure roller 2 to approach the air expansion shaft 1 along the third direction, which can provide sufficient feeding space for the air expansion shaft 1.

[0039] In addition, the frame can be driven by the swing cylinder 6 to make the pressure roller 2 approach or move away from the air shaft 1 in the first direction, forming a large stroke displacement of the pressure roller 2. The swing stroke range covers 0-300mm. During the feeding stage, the swing cylinder 6 retracts to drive the frame and pressure roller 2 away from the air shaft 1. After feeding, the swing cylinder 6 extends to drive the frame and pressure roller to quickly approach the paper roll, forming the first stage of pressing the paper roll on the air shaft 1.

[0040] Furthermore, when pressure needs to be applied after the pressure roller 2 presses onto the roll paper, the secondary pressure cylinder 8 drives the pressure roller 2 to approach or move away from the air expansion shaft 1 along the second direction. During the approach process, a secondary pressure is applied to the pressure roller 2, forming a second-stage pressing on the roll paper on the air expansion shaft 1, increasing the pressing pressure on the roll paper, and solving the edge warping problem caused by traditional single-stage pressing.

[0041] It should be noted here that, as Figure 5 As shown, the first direction is the swing direction of the inclined beam arm 5 with the hinge end with the base 4 as the axis, which is an arc shape; the second direction is the output direction of the secondary pressure cylinder 8, which is a diagonal linear movement in the direction of the air expansion shaft 1; the third direction is the movement direction of the base 4 on the base 10, which is a diagonal linear movement in the direction of the air expansion shaft 1.

[0042] In the present embodiment, as shown in Figure 2 and Figure 3 , the frame body comprises a base 4, the bottom end of the inclined beam arm 5 is hinged on the base 4, the top end of the inclined beam arm 5 is fixed with the cross beam arm 7, the cross beam arm 7 is in the shape of "T" with the inclined beam arm 5 in the front view projection. The cross beam arm 7 is arranged along the axial direction of the press roller 2. The two ends of the swing cylinder 6 are hinged on the base 4 and the inclined beam arm 5 respectively, and it is noted that the swing cylinder 6 is connected at the middle or lower middle part of the inclined beam arm 5.

[0043] Exemplarily, the secondary pressure cylinder 8 is two, which are arranged at the two ends of the cross beam arm 7, and the output end is arranged obliquely downward, and the output end needs to be arranged towards the direction of the air inflation shaft 1. The output end of the secondary pressure cylinder 8 is provided with the shaft seat 3, and the press roller 2 is arranged on the shaft seat 3.

[0044] In the present embodiment, the displacement mechanism comprises a base 10, a displacement cylinder 9 and a connecting table 11. Among them, the base 10 is fixed on the bottom surface of the slitting machine, the base 4 is arranged on the base 10, the displacement cylinder 9 is arranged on the base 10, and is used to drive the base 4 to move along the third direction on the base 10. The connecting table 11 is arranged below the base 4 and is integrally formed with the base 4; the lower surface of the connecting table 11 and the upper surface of the base 10 are formed with an inclined surface 12. The inclined direction of the inclined surface 12 is gradually inclined downward along the third direction, so that the connecting table 11 below the base 4 is inclined to move upward or downward.

[0045] In order to realize the movement of the base 4 on the inclined base 10 driven by the displacement cylinder 9, the front end of the displacement cylinder 9 is hinged on the base 10 in the present embodiment. This design makes the front end of the displacement cylinder 9 swing around the hinge point of the base 10 to be inclined during the gradual downward movement of the base 4.

[0046] In the present embodiment, the displacement cylinder 9, the swing cylinder and the secondary pressure cylinder 8 are all air cylinders, which are connected with the air supply device and the PLC control system of the slitting machine to realize the three-stage linkage of "displacement cylinder 9→swing cylinder 6→secondary pressure cylinder 8". For example, in the loading stage: the displacement cylinder 9 first drives the base 4 to retreat (speed 0.3 m / s), then the swing cylinder 6 retracts (speed 0.5 m / s), and finally the secondary pressure cylinder 8 remains in standby state, and the total response time is ≤1.2 s.

[0047] In addition, in order to improve the stability and direction accuracy of the movement of the base 4, a guide mechanism is arranged between the connecting table 11 and the base 10. Exemplarily, the guide mechanism comprises a boss 13 arranged at the bottom of the connecting table 11, and a guide groove 14 arranged on the top surface of the base 10 and matched with the boss 13. When the base 4 and the connecting table 11 slide along the inclined surface 12, the boss 13 and the guide groove 14 give guidance and position fixing to prevent the base 4 from deviating.

[0048] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the present application, which should be limited only by the appended claims and their equivalents.
