DETAILED DESCRIPTION

[0033] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] See also Figure 1-Figure 5 The technical solution provided by the present invention is: an automated production line for Velcro pasting of hollow boards, comprising a conveying component 1, wherein the conveying component 1 comprises a production box 11, a lower conveying mechanism 12 is provided on the inner wall at the lower end of the production box 11, an upper conveying mechanism 13 is provided on the inner wall at the upper end of the production box 11, a conveying block 16 is provided on both the lower conveying mechanism 12 and the upper conveying mechanism 13, two Velcro automatic pasting devices 14 are installed on the inner wall on one side of the production box 11, and a drying component 15 and a Velcro automatic pasting device 14 are installed on the inner wall on the other side of the production box 11; in specific work, the staff only needs to put the hollow board on the conveying block 16 to complete the entire production process, thereby reducing labor costs.

[0035] See also Figure 2 and Figure 3 , Angle adjustment: The lower conveying mechanism 12 includes a lower adjusting push rod 121 symmetrically arranged on the inner wall of the lower end of the production box 11, and a lower mounting plate 122 is arranged on the lower adjusting push rod 121. A lower conveying belt 124 is installed between the two lower mounting plates 122 through a lower rotating shaft 123, and conveying blocks 16 are evenly arranged on the lower conveying belt 124.

[0036] The upper conveying mechanism 13 includes an upper adjusting push rod 131 symmetrically arranged on the inner wall of the upper end of the production box 11, and an upper mounting plate 132 is arranged on the upper adjusting push rod 131. An upper conveying belt 134 is installed between the two upper mounting plates 132 through an upper rotating shaft 133. The upper conveying belt 134 is evenly provided with slide grooves 135, and a conveying block 16 is slidably connected in the slide groove 135; in specific work, the inclination angle of the hollow board is determined according to the printing situation and the size of the hollow board, that is, the upper adjusting push rod 131 and the lower adjusting push rod 121 are adjusted according to the situation to drive the upper conveying belt 134 and the lower conveying belt 124 to move up and down to adjust the distance between the two, so that the conveying blocks 16 on the upper and lower sides can adapt to the size of the hollow board, and then the position of the upper conveying block 16 is adjusted according to the needs, so that the conveying blocks 16 on the upper and lower sides can adapt to the inclination angle of the hollow board, so that it can adapt to hollow boards of different sizes, and has a wide range of uses.

[0037] See also Figures 2 to 5 , the hollow plate is put in: the conveying block 16 is fixedly arranged on the lower conveying mechanism 12, the conveying block 16 is slidably arranged on the upper conveying mechanism 13, and the conveying block 16 on the upper conveying mechanism 13 and the conveying block 16 on the lower conveying mechanism 12 are not on the same vertical plane;

[0038] The conveying block 16 includes a U-shaped frame 161, in which an L-shaped plate 162 is slidably connected. If necessary, a layer of anti-slip pad can be sleeved on the L-shaped plate 162. Auxiliary springs 163 are evenly arranged between the L-shaped plate 162 and the inner wall of the U-shaped frame 161. The auxiliary springs 163 can adapt to the spacing between the upper and lower rows of lower rotating shafts 123, and can also play a certain clamping effect on the hollow plate. A semicircular groove 164 is provided at the inner corner of the L-shaped plate 162. The semicircular groove 164 can prevent the hollow plate from sliding, and can also play a certain limiting role on the hollow plate, thereby preventing the hollow plate from sliding and falling off when the Velcro automatic pasting device 14 pasted the Velcro.

[0039] One side of the L-shaped plate 162 is slidably connected to the U-shaped frame 161, and the other side extends beyond the U-shaped frame 161. The height of the L-shaped plate 162 extending beyond the U-shaped frame 161 is greater than the depth of the groove of the U-shaped frame 161. The depth of the groove of the U-shaped frame 161 is greater than the spacing between the upper and lower rows of lower rotating shafts 123. The size is set to ensure that the conveying block 16 can always remain in a working state to prevent the hollow plate from falling off the conveying block 16.

[0040] The L-shaped plate 162 in the lower conveying mechanism 12 and the L-shaped plate 162 in the upper conveying mechanism 13 are arranged in a central symmetrical manner. The central symmetrically arranged L-shaped plate 162 is used to ensure that the L-shaped plate 162 plays a limiting and protective role on the inclined hollow plate.

[0041] The lower rotating shafts 123 are arranged in two rows, and the arrangement length of the lower row of rotating shafts is greater than the arrangement length of the upper row of rotating shafts. The rotating shafts arranged in two rows can ensure that when the hollow plate is placed, the conveying blocks 16 on the upper and lower sides have a looser spacing, which is convenient for placing the hollow plate. During the conveying process of the hollow plate, the hollow plate is gradually clamped to prevent the hollow plate from falling.

[0042] During the specific work, the hollow board is placed from the entrance to the L-shaped plate 162 of the conveying block 16. Since the lower conveyor belt 124 has an inclined slope at the entrance and exit, the L-shaped plates 162 on the upper and lower sides have a looser space at the entrance and exit for placing and unloading the hollow board, thereby ensuring the efficiency of placing the hollow board and improving production efficiency. When placing the hollow board on the L-shaped plate 162, the upper and lower sides of the hollow board enter the corresponding semicircular grooves 164. With the rotation of the upper conveyor belt 134 and the lower conveyor belt 124, the hollow board is conveyed into the production box 11, and the Velcro automatic pasting equipment 14 and the drying component 15 work in sequence to process the hollow board.

[0043] See also Figure 1 and Figure 2 , drying the printed surface: the drying component 15 is installed on the side close to the feeding port of the conveying component 1, and at least one drying component 15 is provided on the inner wall of the production box 11. If necessary, the drying component 15 can be set at an angle so that the drying components 15 on both sides are tilted to blow hot air inward, and the drying component 15 in the middle blows air perpendicularly to the hollow plate to avoid the problem of uneven ink on the printed surface caused by unidirectional blowing, so as to ensure the integrity and neatness of the printed surface. The drying component 15 includes a drying push rod 151 installed on the inner wall of the production box 11, and the drying push rod 151 is provided on the inner wall of the production box 11. The top end of the rod 151 is rotatably connected to an auxiliary plate 152, on which air outlets 153 are evenly arranged, and the air outlets 153 are connected to the hot air system through air inlet pipes 154; in specific work, the printed surface of the hollow board is dried by adjusting the distance and angle between the air outlet and the hollow board, which simplifies the steps of drying the printed surface. The inclined hollow board during the processing also avoids the printed surface from being touched and damaged, thereby protecting the integrity of the printed surface and also ensuring the quality of the hollow board packaging box throughout the production process.

[0044] This embodiment also provides an automated production method for the Velcro adhesive tape of a hollow plate, using the automated production line for the Velcro adhesive tape of a hollow plate, the production method comprising the following steps:

[0045] Work preparation: first determine the inclination angle of the hollow plate conveying, and then adjust the conveying blocks 16 on the upper and lower sides of the conveying assembly 1 to a position consistent with the inclination angle of the hollow plate;

[0046] Limiting the hollow plate: Place the hollow plate between the upper and lower conveying blocks 16, and use the upper and lower conveying blocks 16 to limit it, that is, clamp the hollow plate between the upper and lower conveying blocks 16, at this time, the hollow plate is in an inclined state, and drives the hollow plate to move;

[0047] Velcro pasting: When the conveying component 1 drives the hollow board to move, the Velcro automatic pasting device 14 is used to automatically past the Velcro fur surface or the thorn surface of the hollow board;

[0048] Printing surface drying: In the steps of limiting the hollow board and sticking the Velcro, the drying component 15 is used to dry the words printed on the hollow board;

[0049] Hollow board stacking: After the Velcro pasting and the printed surface drying are completed, the processed hollow board is sent out through the conveying component 1 for the next step of stacking.

[0050] In the work preparation, the conveying blocks 16 on the upper and lower sides are not on the same vertical plane.

[0051] By using the above process, the printed surface can be dried, so that the Velcro can be pasted after the hollow board is printed, without waiting for the printed surface to dry, which simplifies the production process while saving time and space, greatly improving production efficiency; at the same time, the inclined Velcro pasting process does not require accurate positioning of the hollow board when placing the hollow board, and the operation is simple and convenient. It optimizes the production steps and further improves production efficiency; the inclined pasting process also avoids damage to the printed surface, ensures the integrity of the printed surface, and makes the quality of the entire production process controllable and of good quality.

[0052] Example 2: See Figure 6 The hollow board products produced by the above-mentioned automated production line and production method have the following characteristics:

[0053] A hollow plate comprises a hollow plate body 2, wherein the hollow plate body 2 comprises a first side plate 21 and a second side plate 22 which are integrally connected, a first crease line 23 is arranged between the first side plate 21 and the second side plate 22, the first side plate 21 comprises a first folding plate 24 which is symmetrically and integrally connected to both sides of the first side plate 21, a second crease line 25 is arranged between the first side plate 21 and the first folding plate 24, the second side plate 22 comprises a second folding plate 26 which is symmetrically and integrally connected to both sides of the second side plate 22, a third crease line 27 is arranged between the second side plate 22 and the second folding plate 26, a connecting plate 28 which is integrally connected to the second side plate 22 is arranged on the side of the second side plate 22 away from the first side plate 21, and a fourth crease line 29 is arranged between the second side plate 22 and the connecting plate 28.

[0054] A first Velcro 20 is symmetrically provided on one side of the first side panel 21, and a second Velcro 2a symmetrically provided on the other side of the second side panel 22 that can be bonded and connected to the first Velcro 20. The first Velcro 20 is a thorny Velcro or a furry Velcro, and the second Velcro 2a is a corresponding furry Velcro or a thorny Velcro.

[0055] The spacing H between the second crease line 25 and the third crease line 27 on the same side of the first side panel 21 and the second side panel 22 is equal to the thickness H of a hollow board body 2, and the third crease line 27 is outside the second crease line 25; in specific work, the setting of multiple crease lines on the hollow board body 2 facilitates the folding of the hollow board body 2 when it is spliced ​​into a hollow board packaging box, and the setting of the second crease line 25 and the third crease line 27 being equal to the thickness of the hollow board ensures that the folded bottom or top surface is smooth and neat when the hollow board is folded into a hollow board packaging box, and further provides a guarantee for the fitting of the first Velcro 20 and the second Velcro 2a.

[0056] Furthermore, the first Velcro 20 is perpendicular to the second crease line 25 , and the second Velcro 2a is parallel to the third crease line 27 .

[0057] There are two first Velcro strips 20 and four second Velcro strips 2a. In actual operation, the corresponding arrangement of the first Velcro strips 20 and the second Velcro strips 2a ensures that the first Velcro strips 20 and the second Velcro strips 2a correspond to each other after being folded into a hollow board packaging box.

[0058] Furthermore, the connecting plate 28 is located between the two third crease lines 27. The setting of the connecting plate 28 facilitates the connection of the two hollow board bodies 2 when splicing the hollow board packaging box, and the length limit also ensures the beauty of the connecting plate 28 after connection. When the two hollow board bodies 2 are connected, the connecting plate 28 is placed on the inside.

[0059] Furthermore, a transport groove 2c is provided on the first side plate 21. The provision of the transport groove 2c facilitates the transport of the hollow board packaging box.

[0060] The above are only preferred embodiments of the present invention.
