Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to an automatic paper feeding packaging equipment for home furnishing boards. Background Technology

[0002] In the storage and transportation of furniture boards, high-strength kraft paper is widely used for surface wrapping and protection to prevent surface scratches, moisture, and contamination. Furniture board packaging equipment is an automated packaging equipment whose core function is to form and seal the flat paper. Its working principle is that the board to be packaged is fed into the equipment by the conveyor system. The equipment automatically pulls and guides the kraft paper from the roll to cover the surface of the board. The forming mechanism tightly wraps the board around its perimeter. Then, the cutting device cuts the paper. Finally, the hot melt adhesive sealing system firmly bonds the paper overlaps to form a sealed paper package protective layer. The entire process of wrapping, forming, and sealing is completed automatically.

[0003] Existing automatic paper feeding packaging equipment for home furnishing boards only uses a transfer shaft to transfer paper by friction. Because two sheets of paper may be attracted by static electricity and stick together, the transfer shaft is prone to carrying two sheets of paper at the same time, causing paper jams, reducing work efficiency and increasing operating costs. Utility Model Content

[0004] This utility model discloses an automatic paper feeding packaging equipment for home furnishing boards, which aims to solve the technical problem that existing home furnishing board packaging equipment relies solely on friction feeding via a transfer shaft, which easily leads to paper jams due to static electricity sticking of the paper, resulting in both reduced efficiency and increased costs.

[0008] In a preferred embodiment, a fixed partition is respectively disposed directly above the two supporting partitions. The two fixed partitions are located directly above the paper outlet of the paper feed compartment. The two fixed partitions and their corresponding supporting partitions are fixedly connected by multiple fixed plates. An infrared thickness gauge is disposed inside each of the two opposing fixed plates to detect the thickness of the paper during transport. A connecting frame is fixedly connected to one side of the fixed plate near the differential gear. One end of the connecting frame is connected to a reversing gear via a bearing. The reversing gear meshes with the differential gear. Two secondary conveying holes are equally spaced between the two supporting partitions, forming two sets of opposing secondary conveying holes. A secondary conveyor shaft is connected to the inside of the feeding hole via bearings. The outer walls of the two secondary conveyor shafts are fitted with the same secondary conveyor belt. The feed end of the secondary conveyor belt is close to the discharge end of the differential belt. Rotating holes are equally spaced on opposite sides of the two fixed partitions. The interiors of the two sets of opposing rotating holes are connected to main conveyor shafts via bearings. The outer walls of the two main conveyor shafts are fitted with the same main conveyor belt. The lower side of the main conveyor belt rolls in contact with the upper sides of the secondary conveyor belt and the differential belt, respectively. A conveyor motor is fixedly connected to one side of one of the fixed partitions. The drive end of the conveyor motor is connected to one end of one of the main conveyor shafts via a coupling.

Under the action of the brake gear, the reversing gear and the differential gear in the anti-sticking component, the differential belt rotates in the opposite direction to the main conveyor belt. At the same time, since the size of the differential gear is larger than that of the brake gear and the reversing gear, the rotation speed of the main conveyor belt is higher than that of the differential belt. Under this action, the upper layer of paper in contact with the main conveyor belt and the lower layer of paper in contact with the differential belt will form a speed difference, thereby quickly separating the two stuck papers, avoiding paper jams, and improving work efficiency.

Detailed Implementation

[0017] 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.

[0018] The automatic paper feeding packaging equipment for home furnishing boards disclosed in this utility model is mainly applied to scenarios where existing home furnishing board packaging equipment relies solely on friction feeding via a transfer shaft, which is prone to paper jams due to static electricity sticking of the paper, resulting in both reduced efficiency and increased costs.

[0019] Reference Figures 1-2 An automatic paper feeding packaging device for household boards includes: a paper feeding compartment 2, a compartment door 1 on one side of the paper feeding compartment 2, a lifting cylinder 8 on the lower inner wall of the paper feeding compartment 2, a support base 7 fixedly connected to the telescopic end of the lifting cylinder 8, and a stack of paper 6 placed on the support base 7; two support partitions 4, which are fixedly connected to the side of the paper feeding compartment 2 away from the compartment door 1, and the support partitions 4 are located directly below the paper outlet of the paper feeding compartment 2; a transfer bracket 5, which is located on the side of the two support partitions 4 away from the paper feeding compartment 2; and an anti-adhesion component 18, which is located between the two support partitions 4, and the anti-adhesion component 18 is used to separate two pieces of paper that have been detected to be stuck together and are conveyed from the paper feeding compartment 2.

[0020] Reference Figures 2-5In a preferred embodiment, the anti-adhesion assembly 18 includes: a differential shaft 1801, connected by bearings to the through holes on opposite sides of two support partitions 4; a differential hole is provided on the inner side of the two support partitions 4 near the paper feed compartment 2; a vent rod 1811 is connected to the differential hole by bearings; the vent rod 1811 has an air inlet at one end and is sealed at the other end; and multiple vent holes are provided at equal intervals on the outer wall of the vent rod 1811; and two rotating rings 1808, respectively connected by bearings to the outer walls of the two ends of the vent rod 1811 located between the two support partitions 4; and a fixed connection between the outer walls of the two rotating rings 1808. The same axle housing 1810, under the action of two rotating collars 1808, is independent of the vent rod 1811 and thus linked with other braking sources. The axle housing 1810 and the differential shaft 1801 are provided with the same differential belt 1803 on the outer wall between the two support partitions 4. The inflatable airbag 1809 is provided on the outer wall of the vent rod 1811. The vent rod 1811 is connected to the inside of the inflatable airbag 1809 through the vent hole. The inflatable airbag 1809 is located inside the axle housing 1810. By continuously inflating and expanding the inflatable airbag 1809, the vent rod 1811 and the axle housing 1810 can be forcibly linked, thereby changing the original movement trajectory of the axle housing 1810.

[0021] In this solution, the anti-adhesion assembly 18 further includes: a differential gear 1802, fixedly connected to one end of the vent rod 1811 located on the outer wall of one of the supporting partitions 4; a multi-head air supply pipe 1807, fixedly connected to the other supporting partition 4 on the side away from the differential gear 1802, the air supply end of the multi-head air supply pipe 1807 being connected to the outer wall of the end of the vent rod 1811 with an air inlet via a bearing, and the air supply end of the multi-head air supply pipe 1807 communicating with the interior of the vent rod 1811; and an air pump 18. 04, fixedly connected to another support partition 4 on the side near the multi-head gas supply pipe 1807, the inflation end of the air pump 1804 is connected to the interior of the multi-head gas supply pipe 1807; the exhaust pump 1805, fixedly connected to another support partition 4 on the side near the multi-head gas supply pipe 1807, the exhaust end of the exhaust pump 1805 is connected to the interior of the air outlet end of the multi-head gas supply pipe 1807; the solenoid valve 1806 is located at the air outlet end of the multi-head gas supply pipe 1807 near the outer wall of the exhaust pump 1805.

[0022] During normal paper transport, the outer side of the vent rod 1811 contacts the differential belt 1803 via the shaft housing 1810. The shaft housing 1810 is fixedly connected to the vent rod 1811 via two rotating rings 1808 through bearings. Under the action of the two rotating rings 1808, the shaft housing 1810 operates independently of the vent rod 1811 and is linked with other braking sources. Therefore, under normal conditions, the rotation of the vent rod 1811 does not affect the rotation of the differential belt 1803. Under normal conditions, the differential belt 1803, under the action of friction, is only affected by the main conveyor belt 12 it rolls into contact with and rotates in the same direction, maintaining a consistent transport speed. When adhesion occurs, the air pump 1804 continuously fills the air bladder 18 through the vent holes inside the vent rod 1811. 09. Inflation causes the air to expand and continuously compress the inner wall of the contact housing 1810. After expanding to its maximum value, the huge friction force forces the housing 1810 and the ventilation rod 1811 to be linked. This causes the differential belt 1803 to rotate in the opposite direction to the main conveyor belt 12 under the action of the brake gear 21, the reversing gear 20, and the differential gear 1802. At the same time, since the size of the differential gear 1802 is much larger than that of the brake gear 21 and the reversing gear 20, the rotation speed of the main conveyor belt 12 is much higher than that of the differential belt 1803. Under this action, the upper layer of paper in contact with the main conveyor belt 12 and the lower layer of paper in contact with the differential belt 1803 will form a speed difference, thereby quickly separating the two stuck papers, avoiding paper jams and improving work efficiency.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6In a preferred embodiment, a fixed partition 11 is respectively disposed directly above the two supporting partitions 4. The two fixed partitions 11 are located directly above the paper outlet of the paper feed chamber 2. The two fixed partitions 11 and the corresponding supporting partitions 4 are fixedly connected to each other by multiple fixed plates 17. Infrared thickness gauges 16 are respectively disposed inside the two opposing fixed plates 17. The infrared thickness gauges 16 are used to detect the thickness of the paper during conveying. A connecting frame 19 is fixedly connected to the side of the fixed plate 17 near the differential gear 1802. One end of the connecting frame 19 is connected to a reversing gear 20 through a bearing. The reversing gear 20 meshes with the differential gear 1802. Two auxiliary conveying holes are equally spaced between the two supporting partitions 4. The auxiliary conveyor shaft 15 is connected to the auxiliary conveyor hole through bearings. The outer walls of the two auxiliary conveyor shafts 15 are fitted with the same auxiliary conveyor belt 10. The feed end of the auxiliary conveyor belt 10 is close to the discharge end of the differential belt 1803. Two fixed partitions 11 have equally spaced rotating holes on opposite sides. The interiors of the two sets of opposing rotating holes are connected to the main conveyor shaft 14 through bearings. The outer walls of the two main conveyor shafts 14 are fitted with the same main conveyor belt 12. The lower side of the main conveyor belt 12 makes rolling contact with the upper sides of the auxiliary conveyor belt 10 and the differential belt 1803, respectively. A conveyor motor 9 is fixedly connected to one side of one of the fixed partitions 11. The drive end of the conveyor motor 9 is connected to one end of one of the main conveyor shafts 14 through a coupling. The end of the conveyor shaft 14 furthest from the conveyor motor 9 and the outer wall of one of the auxiliary conveyor shafts 15 are provided with the same transmission belt 13. A brake gear 21 is fixedly connected to the end of the other main conveyor shaft 14 near the reversing gear 20. The brake gear 21 meshes with the reversing gear 20. Squeezing plates 3 are fixedly connected to both sides of the upper end of the paper feeding bin 2. Rotary roller holes are opened on opposite sides of the upper inner wall of the paper feeding bin 2. Anti-warping rollers 22 are connected to the interior of the opposite rotary roller holes via bearings. Multiple limiting and moving holes are equally spaced on the upper inner wall of the paper feeding bin 2. Sliding blocks 24 are slidably connected inside each of the multiple limiting and moving holes. A circular hole is opened on opposite sides of each set of opposite sliding blocks 24. A sliding block 24 is connected to the interior of each circular hole via a bearing. A conveying shaft 28 is provided with a friction layer on its surface. The outer wall of the multiple conveying shafts 28 is provided with the same connecting plate 27. The two ends of the multiple conveying shafts 28 are connected to each other by multiple linkage belts 29. A drive motor 23 is fixedly connected to one side of one of the sliding blocks 24. The drive end of the drive motor 23 is connected to one end of one of the conveying shafts 28 through a coupling. A sliding rod 26 is fixedly connected to the upper side of the multiple sliding blocks 24. The multiple sliding rods 26 slide in the multiple limiting holes that are equally spaced on one side of the corresponding extrusion plate 3. A compression spring 25 is sleeved on the outer wall of the multiple sliding rods 26. The two ends of the multiple compression springs 25 are fixedly connected to the corresponding sliding block 24 and the extrusion plate 3.

[0024] When workers use the automatic paper feeding packaging equipment for home furnishing boards, they can prevent the paper from warping and getting stuck by setting an anti-warping roller 22 when the paper is transported out of the paper outlet. They can also use an infrared thickness gauge 16 to detect the thickness of the paper during transport. If the thickness of the paper is greater than the set thickness of a single sheet of paper, it indicates that there is adhesion.

[0025] Working principle: When using the automatic paper feeding packaging equipment for furniture boards, the worker first moves the paper stack 6 onto the support seat 7 inside the paper feeding compartment 2 and aligns it. Then, the lifting cylinder 8 raises the paper stack 6. As the multiple transfer shafts 28 come into contact with the paper stack 6, they overcome the elastic force of the multiple compression springs 25 and rise until the paper stack 6 abuts against the anti-warping roller 22. The lifting cylinder 8 is then paused. Subsequently, the drive motor 23 is turned on, and under the action of the linkage belt 29, the multiple transfer shafts 28 rotate clockwise at the same speed. During the rotation, friction occurs... The force, through friction, transports the top layer of paper from the paper feed compartment 2 through the paper outlet. During this process, the anti-curling roller 22 prevents the paper from curling up and causing paper jams as it exits the paper outlet. Before the paper exits, the conveyor motor 9 drives the main conveyor belt 12 to rotate clockwise. Simultaneously, the brake gear 21, fixedly connected to one of the main conveyor shafts 14, rotates clockwise as well. The reversing gear 20 meshes with the brake gear 21, causing the reversing gear 20 to rotate counterclockwise. The needle rotates, and because the differential gear 1802 meshes with the reversing gear 20, the differential gear 1802 drives the vent rod 1811 to rotate clockwise. Under normal conditions, the outer side of the vent rod 1811 contacts the differential belt 1803 via the shaft housing 1810, which is rotatably connected to the vent rod 1811 via bearings by two fixed rotating rings 1808. The shaft housing 1810, under the action of the two rotating rings 1808, operates independently of the vent rod 1811, thus linking with other braking sources. Under normal conditions, the rotation of the vent rod 1811 will not affect the rotation of the differential belt 1803. Under normal conditions, the differential belt 1803 is only affected by the main conveyor belt 12 it rolls into contact with under the action of friction and rotates in the same direction as the main conveyor belt 12. Therefore, when the paper is output from the paper outlet, it is transported to the discharge end under the clamping and capture of the main conveyor belt 12 and the differential belt 1803. During this process, the infrared thickness gauge 16 detects the thickness of the paper during transportation. If the thickness of the paper is greater than the set thickness of a single sheet of paper, it indicates that adhesion has occurred.When paper adhesion occurs, the infrared thickness gauge 16 immediately detects the adhesion and automatically shuts off the drive motor 23, stopping the conveyor shaft 28 from continuing to transport the latter half of the adhered paper. Simultaneously, the air pump 1804 activates, continuously inflating the air bladder 1809 through the vent holes inside the air rod 1811, causing it to expand and continuously press against the inner wall of the contact housing 1810. Once it reaches its maximum expansion, the immense friction forces the housing 1810 and air rod 1811 into a forced linkage. This, in turn, causes the differential belt 1803 to rotate in the opposite direction to the main conveyor belt 12 under the action of the brake gear 21, the reversing gear 20, and the differential gear 1802. Since the differential gear 1802 is significantly larger than the brake gear 21 and the reversing gear 20, the rotation speed of the main conveyor belt 12 is reduced. The rotational speed of the differential belt 1803 is much higher than that of the main conveyor belt 12. Under this action, the upper layer of paper in contact with the main conveyor belt 12 and the lower layer of paper in contact with the differential belt 1803 will form a speed difference. Under the action of friction, the upper layer of paper will separate from the lower layer of paper and be transferred to the transfer bracket 5 for output by the action of the main conveyor belt 12 and the auxiliary conveyor belt 10. Meanwhile, the lower layer of paper will quickly return to the paper feeding bin 2 under the action of the differential belt 1803 and the drive motor 23 driving multiple transfer shafts 28 to rotate counterclockwise, waiting for subsequent transfer. This ensures that only one sheet of paper is transferred at a time. Before transporting the next sheet of paper, the solenoid valve 1806 is opened and the air is discharged from the air bladder 1809 by the exhaust pump 1805, so that the entire anti-sticking component 18 returns to its original state. Then, the above operation is repeated to continue transferring paper.

[0026] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
