Description

Technical Field

[0001] This utility model relates to the technical field of cardboard feeding equipment, and in particular to a feeding device for corrugated paper production. Background Technology

[0002] Corrugated cardboard is a multi-layered bonded structure, consisting of at least one layer of corrugated core paper. It possesses high mechanical strength, enabling it to withstand impacts and drops during handling. Corrugated cardboard is primarily used in the manufacture of cartons, carton fillings, and as packaging material for fragile goods.

[0003] Patent CN214778508U discloses an auxiliary feeding device for corrugated cardboard production. This device's support mechanism supports the corrugated cardboard, dividing it into upper and lower parts. The lower part directly contacts the conveyor belt, while the upper part is supported by the support mechanism. This reduces the amount of corrugated cardboard directly pressed against the conveyor, facilitating the conveyor to transport individual corrugated cardboard pieces sequentially through the separating mechanism. This ensures stable and efficient passage of the corrugated cardboard through the separating plate, improving the separation efficiency. However, this device has the following problems: it requires the corrugated cardboard to be of uniform thickness, and adjustments can only be made after each batch of corrugated cardboard has been fed. It cannot be adjusted according to the different sizes and thicknesses of the corrugated cardboard, resulting in numerous adjustment steps, wasting time, and thus reducing the efficiency of the auxiliary feeding device. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technologies where the device cannot be adjusted at any time and the adjustment steps are numerous and time-consuming, and to propose a feeding device for corrugated paper production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A corrugated paper production feeding device includes a support frame and a conveyor belt. The support frame has a material drop chute, and the conveyor belt is located at the bottom of the support frame and directly below the material drop chute. A transport frame pushed by a cylinder is guided inside the material drop chute. A support plate is provided at one end of the support frame away from the cylinder, and a material discharge port is provided on the support plate. A material feeding rack for storing corrugated paper is provided above the material discharge port.

[0006] In some embodiments, the upper surface of the support is provided with guide shafts on both sides of the material feeding trough, and a movable transport frame is slidably mounted on the guide shafts. The cylinder is located at the end of the support away from the feeding frame, and the output end of the cylinder is connected to the transport frame.

[0007] In some embodiments, the feeding rack includes a box body, the bottom of the box body has a feeding port communicating with the discharge port, the inside of the box body is provided with a horizontal slide rail, the slide rail is slidably engaged with two movable limiting plates, the sides of the box body are provided with positioning bolts for pulling the limiting plates, one end of the positioning bolt passes through the box body and is connected to the limiting plate through a bearing.

[0008] In some embodiments, a through groove is provided at the bottom of the side of the feeding rack, and a stop plate is inserted inside the through groove.

[0009] In some embodiments, the transport frame includes a frame body, with guide rings adapted to the guide shaft on both sides of the frame body, and a transport square hole on the frame body corresponding to the feed port.

[0010] In some embodiments, the two inner sidewalls of the frame are hinged with rotatable transport platforms, which are swung by electric push rods.

[0011] In some embodiments, a sliding groove is provided on the back of the transport platform, and an electric push rod is fixedly installed on the inner side wall of the frame below the transport platform. The output end of the electric push rod is hinged to a sliding block that is adapted to the sliding groove.

[0012] In some embodiments, the upper surface of the frame is provided with a baffle plate to block the corrugated paper at one end.

[0013] In some embodiments, the shielding plate includes a plate body, the end of the plate body near the frame body is provided with a pointed plate, and the upper surface of the plate body is provided with a plurality of rotatable rollers.

[0014] In some embodiments, the bottom of the support is provided with barriers on both sides above the conveyor belt to block the corrugated paper; the barriers include two symmetrically arranged fixing frames, which are located on both sides of the bottom of the support, and the opposite sides of the two fixing frames are provided with detachable baffles by bolts.

[0015] Compared with the prior art, the present invention provides a feeding device for corrugated paper production, which has the following beneficial effects.

[0016] 1. This utility model uses a cylinder to pull the transport frame on the guide shaft, causing the corrugated paper to fall from the feeding rack into the transport frame. After the feeding rack moves away from below the feeding rack, the corrugated paper falls from the transport frame onto the conveyor belt for transport to the next operation. The transport platform can be adjusted according to the thickness of the corrugated paper, allowing different tilt angles to store corrugated paper of different thicknesses. This makes the device adaptable to various thicknesses of corrugated paper and easy to adjust. It can be adjusted directly when transporting the next piece of corrugated paper, improving efficiency.

[0017] 2. In this utility model, the bottom of the feeding rack can be blocked by the baffle plate when the transport rack moves, which can prevent the corrugated paper from falling. This ensures that the transport rack only transports the corrugated paper that has fallen inside each time. At the same time, the internal limit plate of the feeding rack can adjust the appropriate internal space according to the size of the corrugated paper. The conveyor belt is also equipped with a guardrail to prevent the corrugated paper from falling off the conveyor belt.

[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-7 A corrugated paper production feeding device includes a support 1 and a conveyor belt 2. The support 1 has a material drop trough 11. The conveyor belt 2 is located at the bottom of the support 1 and directly below the material drop trough 11. A transport frame 3 pushed by a cylinder 4 is guided inside the material drop trough 11. A pallet 13 is fixedly installed on the end of the support 1 away from the cylinder 4. A discharge port is opened on the pallet 13. A feeding rack 5 for storing corrugated paper is provided above the discharge port.

[0029] Preferably, the upper surface of the support 1 is provided with guide shafts 12 on both sides of the material drop trough 11, and a movable transport frame 3 is slidably fitted on the guide shafts 12. The cylinder 4 is located at the end of the support 1 away from the feeding frame 5, and the output end of the cylinder 4 is connected to the transport frame 3.

[0030] It should be noted that the corrugated paper is stored in the feeding rack 5 and falls down into the transport rack 3. The cylinder 4 pulls the transport rack 3 to move, and then the transport rack 3 separates from the feeding rack 5 and drops the corrugated paper onto the conveyor belt 2 for transport.

[0031] In some embodiments, such as Figure 3 As shown, the feeding rack 5 includes a box 51. The bottom of the box 51 is provided with a feeding port that communicates with the feeding port. The inside of the box 51 is provided with a horizontal slide rail 52, which slides and engages with two movable limiting plates 53.

[0032] It is understandable that multiple slides 52 are arranged in parallel on the two opposite inner side walls of the housing 51; there are no less than two slides 52 on each side; the limiting plate 53 has locking blocks on both sides, which are inserted into the slides 52 to slide, ensuring the smooth movement of the limiting plate 53.

[0033] Furthermore, both sides of the housing 51 are provided with positioning bolts 54 for the top pull limit plate 53.

[0034] The positioning bolt 54 is threadedly assembled with the housing 51, and one end of the positioning bolt 54 passes through the housing 51 and is connected to the limit plate 53 through the bearing.

[0035] By rotating the positioning bolt 54 in and out, the position of the limiting plate 53 in the box 51 can be adjusted; the corrugated paper is located between the two limiting plates 53, and the limiting plates 53 are adjusted according to the size of the corrugated paper to prevent the corrugated paper from tilting due to excessive space inside the box 51, which would cause blockage.

[0036] It is understandable that the end of the positioning bolt 54 is connected to the limiting plate 53 through a bearing, and will not disengage from the limiting plate 53 when the positioning bolt 54 rotates, so that the position of the limiting plate 53 can be adjusted by adjusting the length of the positioning bolt 54.

[0037] In some embodiments, such as Figure 3As shown, a through groove 55 is provided at the bottom of the side of the feeding rack 5, and a stop plate 56 is inserted inside the through groove 55.

[0038] The stop plate 56, once inserted, can prevent the corrugated paper from falling; it can be used in some emergency situations or when the production line needs to be stopped to prevent the corrugated paper from continuing to fall and causing damage.

[0039] In some embodiments, such as Figure 4-6 As shown, the transport frame 3 includes a frame body 31. Guide rings 37 adapted to guide shaft 12 are provided on both sides of the frame body 31. A transport square hole 32 is opened on the frame body 31, and the transport square hole 32 corresponds to the feed port.

[0040] In some embodiments, the two inner sidewalls of the frame 31 are hinged with rotatable transport platforms 33.

[0041] The back of the transport platform 33 is provided with a slide groove 34, and the inner side wall of the frame 31 is fixedly provided with an electric push rod 35 below the transport platform 33. The output end of the electric push rod 35 is hinged with a sliding block 36 that is compatible with the slide groove 34.

[0042] It is understandable that the sliding block 36 and the sliding groove 34 cooperate to achieve sliding, but will not fall off; for example, the sliding block 36 adopts a T-shaped structure.

[0043] Furthermore, a baffle plate 38 for blocking corrugated paper is provided at the end of the upper surface of the frame 31.

[0044] The control rod 35 adjusts the rotation angle of the transport platform 33, allowing the corrugated paper to fall onto the inclined surfaces of the two transport platforms 33. The transport platforms 33 are adjusted according to the thickness of the corrugated paper; the thicker the corrugated paper, the more inclined the transport platform 33 needs to be, and the shorter the extension of the control rod 35, the steeper the transport platform 33 becomes. When the corrugated paper needs to fall, the control rod 35 is retracted to its shortest length, making the inclined surface of the transport platform 33 approximately vertical, allowing the corrugated paper to fall downwards onto the conveyor belt 2.

[0045] It should be noted that the angle of the transport platform 33 is adjusted according to the size and thickness of the corrugated paper so that the corrugated paper falls precisely on the two transport platforms 33, and the upper surface of the bottom corrugated paper is flush with the feeding port at the bottom of the box 51. Moving the frame 31 can bring out the bottom corrugated paper, while the remaining corrugated paper inside the upper feeding rack 5 will be blocked by the baffle plate 38, which acts as a switch for the corrugated paper to fall. The upper surface of the frame 31 is flush with the bottom of the pallet 13. After a single piece of corrugated paper falls onto the frame 31, the upper surface of the corrugated paper is just flush with the upper surface of the frame 31, so that the frame 31 can bring out the corrugated paper when it is moved.

[0046] like Figure 4As shown, the baffle 38 includes a plate body 381. A pointed plate 382 is provided at the end of the plate body 381 near the frame 31. Multiple rotatable rollers 383 are provided on the upper surface of the plate body 381. When the frame 31 moves, it disengages from the bottom of the feeding rack 5. Then, the baffle 38 moves to the bottom of the feeding rack 5 to block the corrugated paper from falling. The pointed shape of the pointed plate 382 prevents the thicker plate body 381 from jamming the corrugated paper, and the rollers 383 reduce the frictional resistance between the corrugated paper and the plate body 381.

[0047] It should be noted that the baffle 38 can be connected to the transport frame 3 and move synchronously with it (the length of the baffle 38 needs to be set according to the maximum distance the transport frame 3 moves); or, a drive mechanism (such as a cylinder or hydraulic cylinder) can be set to reach the bottom of the box 51 during the movement of the transport frame 3 and move back when the transport frame 3 returns.

[0048] In some embodiments, such as Figure 7 As shown, the bottom of the support 1 is also equipped with barriers 6 on both sides above the conveyor belt 2 to block the corrugated paper.

[0049] Specifically, the enclosure 6 includes two symmetrically arranged fixing frames 61, which are located on both sides of the bottom of the support 1. The opposing surfaces of the two fixing frames 61 are equipped with removable baffles 62 by bolts. The function of the enclosure 6 is to prevent the corrugated paper from falling off the conveyor belt 2.

[0050] Furthermore, the position of the baffle 62 can be adjusted by means of bolts and springs, etc., to match the width of the corrugated paper.

[0051] Preferably, a long bolt is fixedly connected to the baffle 62 and passes through the fixing frame 61 before being fitted with a nut; a spring is fitted between the baffle 62 and the fixing frame 61; the position of the baffle 62 can be adjusted by adjusting the degree of screwing in the nut.

[0052] In this invention, the transport frame 3 is moved to a position directly below the feeding frame 5. Corrugated cardboard is placed into the feeding frame 5. The positioning bolt 54 is rotated to adjust the limiting plate 53 according to the width of the corrugated cardboard. The bottom corrugated cardboard will fall into the transport frame 3. The transport platform 33 is adjusted according to the thickness of the corrugated cardboard so that the upper surface of the bottom corrugated cardboard is level with the upper surface of the frame 31. At this time, the cylinder 4 is activated to move the transport frame 3 and bring out the bottom corrugated cardboard. When the transport frame 3 moves away from directly below the feeding frame 5, the baffle plate 38 moves to directly below the feeding frame 5 to block the falling of other corrugated cardboard. When the transport frame 3 completely moves away from directly below the feeding frame 5, the electric push rod 35 is retracted to its shortest length, making the inclined surface of the transport platform 33 approximately vertical, so that the corrugated cardboard falls downward onto the conveyor belt 2. Then the transport frame 3 returns to directly below the feeding frame 5 to transport the next corrugated cardboard. Because each shipment of corrugated paper is independent, the transport rack 3 can be adjusted at any time to fit the thickness or size of the corrugated paper, eliminating the need for adjustments after the transport line stops. The whole process is simple, convenient, and efficient.
