Description

Technical Field

[0001] The utility model relates to the technical field of book binding, in particular to a mounting mechanism of a large-size anti-curling edge pasting device. Background Art

[0002] Large format refers to a larger book format specification, usually used for works or periodicals with more space and thicker content. Due to its large area, during the production process, the book pages are prone to hanging outside the proofreading wheel, that is, curling is prone to occur. Therefore, it is necessary to use an anti-curling device to avoid the occurrence of curling.

[0003] After searching, Chinese patent authorization number CN104589830A discloses a large-format anti-curling posting device for a page-laying machine, comprising multiple arc rods, an arc support plate and a positioning posting device, the arc rods and the arc support plate are fixed under the page storage platform and are located on the same side, at least one arc rod is located on the outer network circumference of the paper-biting wheel, and a gap for the book to run between the arc rod and the outer circumferential surface of the paper-biting wheel, there are two arc support plates and they are located on the two side surfaces of the paper-biting wheel, the outer arc surface of the arc support plate and the outer circumferential surface of the paper-biting wheel are on the same arc surface, at least one arc rod is arranged on the outer arc surface of the arc support plate, and a gap for the book to run between the arc rod and the outer arc surface of the arc support plate, the large-format anti-curling posting device for a page-laying machine of the present invention can prevent curling when posting a large-format book through the cooperation of the arc rod and the arc support plate, thereby improving the operation efficiency of posting and page-laying of a large-format book.

[0004] The existing anti-curling edge pasting device has the following shortcomings: although the device can prevent the occurrence of curling during the pasting process, in order to ensure the normal operation of the device, the staff is required to regularly disassemble and assemble the anti-curling assembly and overhaul it. After the overhaul is completed, one staff member is required to lift the anti-curling edge assembly to the installation position, and another staff member uses bolts to install it. However, since the anti-curling edge assembly is large in size and the installation space in the device is relatively compact, the installation space for the staff is relatively limited, and manual lifting will increase the labor intensity of the staff, which makes it inconvenient for maintenance personnel to install the anti-curling edge assembly. For this reason, we propose an installation mechanism for a large-format anti-curling edge pasting device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 The invention relates to an installation mechanism for a large-format anti-curling and posting device, comprising a support seat 1, a cavity 14 is opened inside the support seat 1, and a double-axis motor 2 is installed at the bottom end of the cavity 14, a rotating shaft 3 is connected to the side of the double-axis motor 2, and a bevel gear set 4 is sleeved on the other side of the rotating shaft 3. The rotation principle of the double-axis motor 2 is the existing technology, which can drive the two sets of rotating shafts 3 to rotate at the same time, a first screw 5 is inserted into the interior of the bevel gear set 4, and a sleeve rod 6 is sleeved on the outer side of the first screw 5, and a connecting plate 7 is connected to the top of the sleeve rod 6, and a pushing plate 8 is covered on the top of the connecting plate 7. The bevel gear set 4 is composed of two sets of bevel gears, and the two sets of bevel gears are respectively sleeved on the outer side of the first screw 5 and the outer side of the rotating shaft 3, so that when the rotating shaft 3 rotates, the first screw 5 can be driven to rotate in the reverse direction, and the thread directions of the two symmetrical first screws 5 are opposite, and the sleeve rod 6 is opened inside The internal thread matched with the first screw 5, so that the two sets of sleeve rods 6 can be lifted at the same time.

[0024] Further, see Figure 1 and Figure 2 It can be known that guide rods 9 are connected to the surface angle positions of the bottom end of the connecting plate 7, and guide grooves compatible with the guide rods 9 are opened inside the support seat 1. Through the mutual cooperation of four groups of guide rods 9 and guide grooves, the connecting plate 7 can be guided to ensure the stable up and down movement of the connecting plate 7.

[0025] Further, see Figure 2It can be known that a cylinder 11 is installed at the center position of the connecting plate 7, and the end of the cylinder 11 extends to the outside of the connecting plate 7 and is connected to the pushing plate 8. The telescopic principle of the cylinder 11 is a prior art and will not be elaborated here. By driving the cylinder 11, the pushing plate 8 can be automatically pushed and retracted without manual operation by the staff, thereby further reducing the labor intensity of the staff.

[0026] Further, see Figure 2 and Figure 4 It can be seen that the longitudinal section of the push plate 8 is set as a U-shaped structure, the inner side of the push plate 8 is symmetrically connected with a guide bar 10, and the side wall of the connecting plate 7 is provided with a slide groove compatible with the guide bar 10. Through the mutual cooperation of the guide bar 10 and the slide groove, when driven by the cylinder 11, the stability of the push plate 8 during the sliding process can be effectively guaranteed.

[0027] Further, see Figure 4 It can be known that the inside of the pushing plate 8 is connected to the second screw 15 through a bearing, and the outside of the second screw 15 is sleeved with two groups of screw sleeves 12, the top ends of the two groups of screw sleeves 12 are connected to the clamping plate 13 through a connecting rod, and the other end of the second screw 15 extends to the outside of the pushing plate 8, so that the staff can rotate it conveniently. The inside of the pushing plate 8 is provided with a moving groove adapted to the connecting rod, so as to meet the movement requirements of the screw sleeve 12. In addition, the outer surface of the second screw 15 is provided with two groups of external threads in opposite directions. Therefore, when the second screw 15 rotates, it can drive the two groups of screw sleeves 12 to move in opposite directions, thereby realizing the clamping of the anti-curling component.

[0028] Further, see Figure 2 It can be seen that a rubber pad is glued to one side of the clamping plates 13 that are close to each other, and anti-slip grooves are evenly arranged on the outer surface of the rubber pad. The rubber pad and the anti-slip grooves are not shown in the figure. Through the mutual cooperation of the two, the clamping effect of the anti-curling component can be effectively improved.

[0029] Further, see Figure 2 It can be seen that there are two groups of rotating shafts 3, and the two groups of rotating shafts 3 are symmetrically distributed about the central axis of the dual-axis motor 2. Since there are two groups of rotating shafts 3, there are also two groups of bevel gear sets 4, first screw rods 5 and sleeve rods 6, which can improve the stability of the connecting plate 7 during the lifting process.

[0030] Working principle: After the utility model has been used for a period of time, the anti-curling assembly installed in the middle part of the comparison document storage table can be disassembled for maintenance. After the maintenance is completed, the staff can lift the anti-curling assembly onto the push plate 8, and then the second screw 15 can be rotated to make the screw sleeve 12 threadedly cooperate with it, which can drive the two sets of screw sleeves 12 to move towards each other inside the push plate 8. At this time, the two sets of clamping plates 13 can be close to each other and abut against the side wall of the anti-curling assembly to achieve the clamping of the anti-curling assembly. Then the staff can start the work of the double-axis motor 2, so that it drives the two sets of rotating shafts 3 to rotate in the same direction, through the mutual cooperation of the first screw 5 and the bevel gear set 4, that is, The two sets of sleeve rods 6 can drive the connecting plate 7 to move to adjust the height of the pushing plate 8. When the height of the anti-curling assembly is adjusted to correspond to the height of the storage platform installation area, the staff can start the cylinder 11 again, so that the pushing plate 8 can slide under force. At this time, the anti-curling assembly placed above the pushing plate 8 can be extended to the installation area of ​​the storage platform, and then the staff can use bolts to quickly install the anti-curling assembly in the storage platform. After the installation is completed, the staff can rotate the second screw 15 in the opposite direction, so that the two sets of clamping plates 13 move away from each other. At this time, the pushing plate 8 can be retracted by the drive of the cylinder 11. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.
