Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper production, in particular to a flat pressing device for corrugated paper production. Background Art

[0002] Corrugated cardboard is made of single-layer or multi-layer corrugated cardboard and flat paper. It has good compressive strength and shock resistance, and can withstand certain pressure, impact and vibration. In addition, corrugated paper is more environmentally friendly and easy to degrade, and can reduce packaging costs. It has now developed into a basic packaging material. Before corrugated paper is made into cartons, the uneven corrugated cardboard needs to be flattened, which can improve the quality of the cartons. Existing corrugated paper flattening and shaping devices generally have the problem of low flattening rate.

[0003] For example, a Chinese utility model patent with the announcement number CN216804661U discloses a flattening device for corrugated paper production. Although the scheme uses a lifting screw, a pressing plate to flatten the corrugated paper, and a telescopic spring and a clamp to fix the corrugated paper, the operation is cumbersome, and the pressure of the pressing plate is used to flatten each sheet, and the heating wire heats one sheet of corrugated paper at a time. The heat conduction time may be long, which is not suitable for use on an assembly line. Based on this, a flattening device for corrugated paper production is proposed. Utility Model Content

[0004] In order to solve the technical problems in corrugated paper production, the utility model provides a flat pressing device for corrugated paper production.

[0005] The utility model is implemented by the following technical scheme: a flattening device for corrugated paper production, comprising a swing rod, a base and a corrugated paper box above the base, a No. 4 slide slot is provided on the top of the corrugated paper box, a heat conduction limit plate is provided on the lower side of the No. 4 slide slot, a No. 1 slide slot is provided on the heat conduction limit plate, a cardboard feeding mechanism for adding auxiliary corrugated paper boards into the corrugated paper box is provided on the upper side of the corrugated paper box, a cardboard fixing mechanism for fixing the corrugated paper box is provided on the lower side of the corrugated paper box, a cardboard heating mechanism for ironing the cardboard is provided on the lower side of the heat conduction limit plate, and a cardboard driving mechanism for flattening the cardboards in the corrugated paper box one by one and then pushing them out is provided below the No. 1 slide slot.

[0006] As a further improvement of the above solution, the cardboard feeding mechanism includes a feeding slide fixedly connected to the upper side of the corrugated paper box.

[0007] As a further improvement of the above solution, the carton fixing mechanism includes two vertical plates fixedly connected to the upper side of the base and fixedly connected to the lower side of the corrugated carton.

[0008] As a further improvement of the above solution, the paperboard heating mechanism includes a high-temperature steam box fixedly connected to both sides of the lower side of the heat-conducting limiting plate.

[0009] As a further improvement of the above scheme, the cardboard driving mechanism includes a servo motor fixedly connected to one side of a vertical plate, the output end of the servo motor is fixedly connected to a No. 2 connecting plate, one end of the No. 2 connecting plate is rotatably connected to a No. 1 connecting plate, and one end of the No. 1 connecting plate is provided with a rocker driving mechanism that causes the rocker to reciprocate forward and backward.

[0010] As a further improvement of the above scheme, the rocker arm driving mechanism includes a limit platform fixedly connected between the two vertical plates, a No. 2 slide groove slidingly connected to one side of the No. 1 connecting plate is provided on the lower side of the limit platform, a No. 3 slide groove is provided on the limit platform, and a slider slidably connected to one end of the No. 1 connecting plate and to the lower side of the rocker arm is slidably connected to the inner side of the No. 3 slide groove.

[0011] As a further improvement of the above solution, one end of the rocker arm is fixedly connected to a push plate that cooperates with the fourth slide groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model can push the cardboards in the corrugated paper box one by one through the cooperation of the slider, the limit table, the No. 1 connecting plate and the swing rod. During the pushing process, the corrugated paperboard at the bottom layer bears the gravity of the corrugated paper pile stacked above, so as to be flattened. Moreover, after each corrugated paper is pushed out from the feeding slide plate, from the first to the last one, during the continuous process, the pressure of the cardboard above will continue to flatten the corrugated paperboard, so the flattening effect is more time-saving and labor-saving, and the operation is extremely simple.

[0014] 2. The utility model cooperates with the heat conduction limit plate and the high-temperature steam box. The heat of the high-temperature steam is transferred from the bottom to the tightly pressed corrugated cardboard above through the heat conduction limit plate by heat conduction. The high temperature can not only dry the newly bonded corrugated cardboard to prevent the cardboard from mold, but also use the high temperature to iron the cardboard to achieve a better flattening effect.

[0015] 3. The utility model can directly connect to the corrugated paper production line through the cooperation between the feeding slide plate and the corrugated paper box. The paperboard flows into the corrugated paper box, and the corrugated paper box can limit and fix the paperboard, so the flattening effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example:

[0023] Please combine Figure 1-Figure 3 A flat pressing device for corrugated paper production in this embodiment includes a swing rod 5, a base 1 and a corrugated paper box 8 above it. A No. 4 slide 17 is opened on the corrugated paper box 8. The height of the No. 4 slide 17 is adapted to the average thickness of the corrugated paper board, and the height of the No. 4 slide 17 should not be greater than the thickness of the corrugated paper board. A heat conduction limit plate 7 is arranged on the lower side of the No. 4 slide 17. The upper surface of the heat conduction limit plate 7 is smooth, which reduces the friction between the heat conduction limit plate 7 and the corrugated paper board, and is convenient for pushing out of the corrugated paper box 8. , without damaging the surface structure of the cardboard, a No. 1 chute 10 is provided on the heat-conducting limit plate 7, a cardboard feeding mechanism for auxiliary corrugated cardboard added to the corrugated cardboard box 8 is provided on the upper side of the corrugated cardboard box 8, a cardboard fixing mechanism for fixing the corrugated cardboard box 8 is provided on the lower side of the corrugated cardboard box 8, a cardboard heating mechanism for ironing the cardboard is provided on the lower side of the heat-conducting limit plate 7, and a cardboard driving mechanism for flattening the cardboards in the corrugated cardboard box 8 and pushing them out one by one is provided below the No. 1 chute 10.

[0024] Please combine Figure 1 As shown, the cardboard feeding mechanism includes a feeding slide plate 9 fixedly connected to the upper side of the corrugated cardboard box 8, and the feeding slide plate 9 can be adjusted according to specific circumstances, mainly so that the corrugated cardboard can slide down from the feeding slide plate 9 and fall smoothly and horizontally into the corrugated cardboard box 8. The cardboard fixing mechanism includes two vertical plates 2 fixedly connected to the upper side of the base 1 and fixedly connected to the lower side of the corrugated cardboard box 8. The cardboard heating mechanism includes a high-temperature steam box 6 fixedly connected to both sides of the lower side of the heat-conducting limit plate 7. The high-temperature steam box 6 can be embedded in the inner side of the heat-conducting limit plate 7, so that the heat conduction effect is better and it is more conducive to saving resources. The heat-conducting limit plate 7 is made of copper plate, which has excellent thermal conductivity and the cost is controlled within a reasonable range.

[0025] Please combine Figure 2 As shown, the paperboard driving mechanism includes a servo motor 3 fixedly connected to one side of a side vertical plate 2, the output end of the servo motor 3 is fixedly connected to a No. 2 connecting plate 14, one end of the No. 2 connecting plate 14 is rotatably connected to a No. 1 connecting plate 13, and one end of the No. 1 connecting plate 13 is provided with a rocker driving mechanism that causes the rocker 5 to reciprocate forward and backward.

[0026] Please combine Figure 1 and Figure 3 As shown, the rocker arm driving mechanism includes a limit platform 12 fixedly connected between the two vertical plates 2, a No. 2 slide groove 15 slidably connected to one side of the No. 1 connecting plate 13 is provided on the lower side of the limit platform 12, a No. 3 slide groove 16 is provided on the limit platform 12, and a slider 4 rotatably connected to one end of the No. 1 connecting plate 13 and rotatably connected to the lower side of the rocker arm 5 is slidably connected to the inner side of the No. 3 slide groove 16, and one end of the rocker arm 5 is fixedly connected to a push plate 11 matched with the No. 4 slide groove 17. It is particularly important to note that the weight of the rocker arm 5 and one end of the push plate 11 is less than the weight of the other end of the rocker arm 5, so that the rocker arm 5 can automatically rotate and reset when it returns to the other side.

[0027] The implementation principle of a flat pressing device for corrugated paper production in the embodiment of the present application is as follows: the corrugated paperboard on the assembly line passes through the feeding slide plate 9, flows into the corrugated paper box 8 and is neatly stacked together, the servo motor 3 is started, the No. 2 connecting plate 14 rotates, and the No. 1 connecting plate 13 pushes the slider 4 to slide back and forth along the direction of the limit platform 12. At this time, the push plate 11 on the highest end of the swing rod 5 contacts the corrugated paperboard of the lowest layer through the slide groove 10 and pushes it out from the bottom side. The high-temperature steam box 6 is connected to the high-temperature steam, and the heat is transferred to the upper corrugated paperboard through the heat-conducting limit plate 7. The excess heat will diffuse upward step by step. When the No. 1 connecting plate 13 pulls the slider 4 back, the swing rod 5 and the push plate 11 are blocked at this time, rotate downward, and smoothly pass through the No. 1 slide groove 10. At this time, since the weight of one end of the swing rod 5 with the push plate 11 is less than the weight of the other end of the swing rod 5, the swing rod 5 and the push plate 11 will automatically reset and rotate under the action of gravity, and the push plate 11 returns to the highest point again, and enters the next cycle of pushing the corrugated paperboard.

[0028] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
