Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a safety protection device for an unwinding part of a slitting machine. Background Art

[0002] The slitting machine is a mechanical device that cuts wide paper, mica tape or film into multiple narrow materials. It is used in non-woven fabrics, mica tape, paper, insulation materials and various film material industries. However, the raw materials used in the slitting machine are in the unwinding roller clamping head of the slitting machine. After the raw materials are put on and locked, the equipment is started. During the overall operation of the slitting machine, due to various reasons such as wear of the clamping head of the locking part, wear and defects of the clamping part of the raw materials, there is a situation that the raw materials or film rolls are thrown off from the clamping head. After this happens, the falling of the raw materials or film rolls is likely to cause injuries to the staff and cause safety accidents.

[0003] In principle, this type of safety accident is strictly prohibited, but it often occurs due to various reasons such as operator negligence, equipment failure, or raw material defects.

[0004] Therefore, considering the safety of personnel, equipment and products, we have designed a safety protection device for the unwinding part of the slitting machine. Utility Model Content

[0005] In order to overcome the deficiencies in the background technology, the utility model discloses a safety protection device for an unwinding part of a slitting machine.

[0006] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0007] A safety protection device for an unwinding part of a slitting machine, comprising:

[0008] The material connection structure comprises an arc-shaped plate, both ends of the inner side of the arc-shaped plate are smoothly transitioned with inclined straight rods, and the outer ends of the inclined straight rods are higher than the inner ends of the inclined straight rods;

[0009] There are two spring telescopic rods, the upper ends of which are respectively connected to a section of the two inclined straight rods away from the arc-shaped plate in a one-to-one correspondence, so as to buffer the inclined straight rods;

[0010] Wherein, the outer side of the arc-shaped plate is higher than the inner side of the arc-shaped plate, so as to prevent the material from rolling out.

[0011] Preferably, an elastic drawstring is provided between the outer ends of the two inclined straight rods.

[0012] Preferably, it further comprises a supporting structure, and the bottom of the arc-shaped plate is correspondingly hinged to the top of the supporting structure.

[0013] Preferably, the lower end of the spring telescopic rod is hinged with a fixing seat, and the upper end of the spring telescopic rod is hinged with a corresponding inclined straight rod.

[0014] Preferably, the minimum limit height of the spring telescopic rod is lower than the height of the supporting structure, so that when the spring telescopic rod is at the minimum limit height, the material rolls back to the outer end of the inclined straight rod.

[0015] Preferably, the outer end of the inclined straight rod is provided with a stopper extending upward to prevent the rolled-back material from falling.

[0016] Preferably, a pressing portion is provided below the outer end of the inclined straight rod, so that the inclined straight rod can be rotated downward by stepping on it.

[0017] Preferably, a buffer layer is provided on the top surface of the material connection structure.

[0018] Preferably, the distance between the outer ends of the two inclined straight rods is not less than the distance between the inner ends thereof.

[0019] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0020] 1. When the material falls accidentally, it is received by the outer ends of the two inclined straight rods. At this time, the spring telescopic rod contracts to reduce the collision potential energy between the material and the inclined straight rod. At this time, the outer end of the inclined straight rod is still higher than the inner end, and the material rolls toward the arc plate until it gradually stops at the bottom of the upper surface of the arc plate under the action of the arc plate; this can prevent the material from falling directly on the ground, which can not only prevent the material from being damaged, but also effectively prevent the material from hitting the staff;

[0021] 2. The setting of the elastic pull rope can remind the staff whether they have entered the dangerous area and urge them to keep a safe distance. At the same time, the staff can enter the elastic pull rope blocking area to work at other time periods;

[0022] 3. The setting of the supporting structure and the spring telescopic rod can make the material on the safety protection device roll back to the outer end of the inclined straight rod, making it convenient to take out the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 1, in combination with the attached Figure 1 , a safety protection device for the unwinding part of a slitting machine, comprising a material receiving structure 1 and a spring telescopic rod 2:

[0033] The material receiving structure 1 has an arc-shaped plate 11, and both ends of the inner side of the arc-shaped plate 11 are smoothly transitioned with inclined straight rods 12, that is, when the film roll rolls, the connection between the arc-shaped plate 11 and the inclined straight rod 12 will not cause damage to the film roll; the outer end of the inclined straight rod 12 is higher than the inner end of the inclined straight rod 12;

[0034] As required, a buffer layer 6 is provided on the top surface of the material receiving structure 1, that is, a buffer layer 6 is provided on the upper surface of the curved plate 11 and the upper surface of the inclined straight rod 12; this arrangement prevents the upper surface of the curved plate 11 and the upper surface of the inclined straight rod 12 from being uneven and the presence of edges from causing damage to the outer layers of the film roll and resulting in waste. It should be noted that when the buffer layer 6 is present, the smooth transition at the connection between the curved plate 11 and the inclined straight rod 12 may have a certain degree of unevenness to reduce the difficulty of production, but it must be ensured that no damage is caused to the material. At the same time, the presence of the buffer layer 6 can also appropriately reduce the requirements for the flatness of the upper surface of the curved plate 11 and the upper surface of the inclined straight rod 12. As required, the buffer layer 6 can be fixed by gluing.

[0035] There are two spring telescopic rods 2, and the upper ends of the two spring telescopic rods 2 are respectively connected to a section of the two inclined straight rods 12 away from the arc plate 11, which is used to buffer the inclined straight rods 12; that is, when the outer ends of the two inclined straight rods 12 receive materials (raw materials or film rolls), they can play a buffering role to prevent the position where the material contacts the inclined straight rods 12 from being damaged.

[0036] The outer side of the arc plate 11 is higher than the inner side of the arc plate 11 so as to prevent the material from rolling out.

[0037] When installing this embodiment, first support the bottom of the arc plate 11 on the ground 110mm to 140mm in front of the center line of the long side of the slitting machine slide, and then fix the lower end of the spring telescopic rod 2 on the ground at the corresponding position.

[0038] During use, when materials fall accidentally, the materials are received by the outer ends of the two inclined straight rods 12. At this time, the spring telescopic rod 2 contracts to reduce the collision potential energy between the materials and the inclined straight rod 12. At this time, the outer ends of the inclined straight rods 12 are still higher than the height of their inner ends, and the materials roll toward the arc plate 11 until they gradually stop at the bottom of the upper surface of the arc plate 11 under the action of the arc plate 11. This can prevent the materials from falling directly on the ground, which can not only prevent the materials from being damaged, but also effectively prevent the materials from hitting the staff.

[0039] It should be noted that the closer the outer end of the inclined straight rod 12 is to the material installation position, the safer it is. Therefore, during implementation, the height of the outer end of the inclined straight rod 12 should be raised as much as possible without affecting normal operations.

[0040] In the example, according to the size of the existing slitting machine, the arc height of the arc plate 11 is 30mm-50mm, the circumference of the arc plate 11 is 130mm-160mm, and the angle between the line connecting the two sides of the arc plate 11 and the horizontal plane is 45°-55°.

[0041] In the example, the angle between the inclined straight rod 12 and the ground is 20° to 30°.

[0042] As required, an arc-shaped support portion may be provided at the inner end of the inclined straight rod 12 , and an embedding groove for embedding the arc-shaped plate 11 is provided on the upper surface of the arc-shaped support portion.

[0043] As needed, combine with Figure 4 The two inclined straight rods 12 can be arranged in parallel. At this time, the length of the arc plate 11 is close to the width of the slitting machine, so that the two inclined straight rods 12 are respectively located on both sides of the slitting machine, so that the safety protection device does not occupy the working area.

[0044] As needed, combine with Figure 5 The two inclined straight rods 12 can also be distributed in a trumpet shape, that is, the distance between the outer ends of the two inclined straight rods 12 is greater than the distance between the inner ends thereof, so that the outer ends of the two inclined straight rods 12 are located at the two sides of the slitting machine. In this case, the length of the curved plate 11 can be effectively reduced, and the material used for the safety protection device can be reduced. It should be noted that it is necessary to ensure that the curved plate 11 can stably support the material. According to the needs, the angle between the two inclined straight rods 12 is between 60° and 90°.

[0045] As needed, combine with Figure 6 The spring telescopic rod 2 may include an outer tube 21, a telescopic rod 22 and a spring 23. The inner cavity of the outer tube 21 is provided with a spring 23 and the telescopic rod 22 at the same time. The upper end of the telescopic rod 22 extends out of the outer tube 21 and is correspondingly connected to the inclined straight rod 12; wherein the lower end of the telescopic rod 22 is provided with an expanded neck, and the upper end of the outer tube 21 is provided with a reduced diameter portion, and the expanded neck is limited to be separated from the inner cavity of the outer tube 21 by the reduced diameter portion, so as to limit the maximum limit height of the spring telescopic rod 2.

[0046] As required, the maximum height limit of the spring telescopic rod 2 can also be limited by other structural methods, for example, in combination with the attached Figure 7 , the outer tube 21 is provided with an axial waist hole which penetrates radially, and the lower end of the telescopic rod 22 is provided with a bayonet 24 which is inserted into the axial waist hole. When the bayonet 24 contacts the upper end of the axial waist hole, the spring telescopic rod 2 is at the maximum limit height. For another example, the telescopic rod 22 is provided with an axial waist hole which penetrates radially, and the upper end of the outer tube 21 is provided with a bayonet 24 which penetrates the axial waist hole. When the bayonet 24 contacts the lower end of the axial waist hole, the spring telescopic rod 2 is at the maximum limit height.

[0047] Embodiment 2, combined with the attached Figure 1 , 4-5. A safety protection device for the unwinding part of a slitting machine. On the basis of the first embodiment, in order to prevent the staff from being in a dangerous area when unwinding materials, that is, even if the materials are received by the inclined straight rods 12, there is still a risk of being hit by the materials; an elastic pull rope 3 is provided between the outer ends of the two inclined straight rods 12; in this way, when the staff touches the elastic pull rope 3, it indicates that the staff's calf is about to be in a dangerous area, reminding the staff to step back and keep a safe distance, thereby further improving safety. At the same time, in other time periods (when the slitting machine is not working), the staff can enter the area blocked by the elastic pull rope 3 to perform operations.

[0048] Embodiment 3, in combination with the attached Figure 1-5 , a safety protection device for the unwinding part of a slitting machine, based on the first or second embodiment, in order to prevent the movement of the arc plate 11 causing friction between the arc plate 11 and the ground, causing wear of the ground and the arc plate 11; it also includes a support structure 4, and the bottom of the arc plate 11 is correspondingly hinged to the top of the support structure 4. In other words, the support structure 4 and the arc plate 11 can have an angle change, for example, the support structure 4 can be connected to the arc plate 11 through a rotating part such as a pin; the support structure 4 can also be provided with an arc-shaped supporting part at its top, and the arc plate 11 is supported by the arc-shaped supporting part, so that the arc plate 11 can rotate relative to the support structure 4.

[0049] During installation, the support structure 4 can be fixed to the ground by anchor bolts. As required, a plurality of support structures 4 can be provided at intervals along the length direction of the arc-shaped plate 11.

[0050] In this embodiment, the lower end of the spring telescopic rod 2 is hinged with a fixing seat 5 , and the upper end of the spring telescopic rod 2 is hinged with the corresponding inclined straight rod 12 .

[0051] Embodiment 4, in combination with the attached Figure 2-3 , a safety protection device for the unwinding part of a slitting machine. On the basis of the third embodiment, in order to facilitate the removal of the material received by the safety protection device, the minimum limit height of the spring telescopic rod 2 is lower than the height of the supporting structure 4, so that when the spring telescopic rod 2 is at the minimum limit height, the material rolls back to the outer end of the inclined straight rod 12; that is, the spring telescopic rod 2 can be compressed by pressing down the outer end of the inclined straight rod 12 until the outer end of the inclined straight rod 12 is lower than the inner end of the inclined straight rod 12. At this time, the material can roll back to the outer end of the inclined straight rod 12, and the material can be taken out at this time.

[0052] Furthermore, in order to prevent the rolled-back material from falling, an upwardly extending stopper 121 is provided at the outer end of the inclined straight rod 12 .

[0053] In order to prevent the rolling back material from hitting the part where the staff presses down the outer end of the inclined straight rod 12, a pressing part 122 is set below the outer end of the inclined straight rod 12; that is, the staff can press down the pressing part 122 to make the inclined straight rod 12 rotate downward. At this time, the rolling back material will not touch the staff, thereby improving safety.

[0054] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
