Description

Technical Field

[0001] The present invention relates to the technical field of edge banding packaging equipment, and particularly relates to an intelligent edge banding packing device. Background Art

[0002] An edge banding is a material for protecting, decorating, and beautifying the cross-section of furniture boards, which can make a piece of furniture show an overall effect with clear wood grains and colorful colors. The main component of the PVC edge banding is polyvinyl chloride, which is obtained through processes such as mixing, calendering, and vacuum thermoforming. At present, there are also winding and packing equipment for edge banding on the market, but these devices usually wind the edge banding first and then transport the material roll to the bundling device.

[0003] However, during the process of discharging the material roll from the winding disk after winding and the subsequent transfer process, the material roll is prone to deformation and dispersion, and the connection between the wound material roll and the winding disk is tight, making it difficult to discharge the material. Summary of the Invention

A connecting bar extending vertically downward is provided at the end of the pushing block away from the inner support block. A limiting column perpendicular to the axis of the turntable and the axis of the sliding sleeve is provided at the bottom of the connecting bar. The limiting column is slidably installed in a first limiting groove provided on the limiting bar. The first limiting groove extends along the length direction of the limiting bar. The end of the first limiting groove away from the inner support block is connected to an inclined second limiting groove, and the end of the second limiting groove away from the inner support block extends towards the direction close to the axis of the turntable.

[0006] Preferably, the linear drive unit includes a first linear driver fixedly installed on the frame. The working end of the first linear driver moves along the axis direction of the turntable.

One end of the connecting rod away from the pushing block is connected to the rotating ring.

[0007] Preferably, the linear distance between the lowest ends of the first limiting groove and the second limiting groove is not greater than the difference between the length of the insertion hole and the length of the limiting block.

[0008] Preferably, the rotary drive unit includes a rotary driver fixedly installed on the frame. The working end of the rotary driver is drivingly connected to a rotating shaft. The turntable is coaxially installed on the rotating shaft.

[0009] Preferably, the limiting strip is provided with a guiding hole extending parallel to the length direction of the insertion hole. A guiding rod provided on the side of the turntable away from the inner supporting block is inserted into the guiding hole.

[0010] Preferably, on both sides of one end of the pushing block facing the inner supporting block, there are protruding positioning bumps. On the side of the sliding sleeve of the turntable facing the inner supporting block, there is a positioning groove. The positioning groove extends along the axis direction of the turntable and has the same length as the length of the positioning bump.

[0011] Preferably, on the side of the rotating ring away from the turntable, there are positioning insertion holes with the same number as the belt threading grooves.

[0014] The beneficial effects of the present invention compared with the prior art are: First, the strapping groove provided on the turntable of the present invention is located between two adjacent inner support blocks.

The material roll maintains a fixed shape during the unloading and transportation process, avoiding looseness and deformation, and ensuring the packaging quality.

[0015] Secondly, the pushing block in the present invention cooperates with the linear drive unit to push the wound edge banding strip material roll to unload while driving the inner support block to retract toward the turntable axis, releasing the tight connection between the material roll and the inner support block, solving the unloading difficulty problem of traditional equipment and improving unloading efficiency.

[0016] Thirdly, the elastic positioning rod and the positioning socket in the present invention cooperate with the distance sensor for real-time monitoring to ensure that the strapping groove is accurately aligned with the working end of the strapping device, avoid bundling deviation, and ensure that the material rolls are bundled tightly and regularly.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figures 1 to 13 : An intelligent packaging device for edge banding strips, comprising a frame 1 and a turntable 2 rotatably mounted on the frame 1. A rotary drive unit 2a for driving the turntable 2 to rotate is provided on the frame 1. A feeding device 1a, a shearing device 1b and a banding device 1c are arranged on the frame 1 around the circumference of the turntable 2. A plurality of inner support blocks 3 are slidably mounted on the turntable 2, and the inner support blocks 3 are evenly distributed at equal angles around the axis of the turntable 2. The edge banding strips conveyed by the feeding device 1a are wound around the outside of the inner support blocks 3. There is a spacing between the side walls of two adjacent inner support blocks 3. A banding slot 2b extending radially along the turntable 2 and located between two adjacent inner support blocks 3 is provided on the frame 1. The banding device 1c bundles the wound edge banding strips through the banding slot 2b. A pushing block 4 with the same number as the inner support blocks 3 is slidably mounted on the frame 1. A linear drive unit 4a for driving the pushing block 4 to move axially along the turntable 2 is provided on the frame 1. When the pushing block 4 moves towards the side of the turntable 2 where the inner support blocks 3 are provided, it drives all the inner support blocks 3 to move synchronously towards the axis of the turntable 2.

[0034] In this application, the feeding device 1a conveys the edge banding strips to the turntable 2, and the rotary drive unit 2a drives the turntable 2 to rotate, so that the edge banding strips are wound around the outside of the inner support blocks 3 evenly distributed at equal angles around the axis of the turntable 2. When the edge banding strips are wound to a set length or number of turns, the banding device 1c bundles the wound edge banding strips through the banding slot 2b which is located between two adjacent inner support blocks 3 and extends radially along the turntable 2. After bundling, the shearing device 1b cuts off the edge banding strips. Subsequently, the linear drive unit 4a drives the pushing block 4 to move axially along the turntable 2 towards the side of the turntable 2 where the inner support blocks 3 are provided. While the pushing block 4 moves, it drives all the inner support blocks 3 to move synchronously towards the axis of the turntable 2, reducing the connection tightness between the coil and the inner support blocks 3, facilitating the unloading of the coil from the turntable 2 and completing the entire packaging process. The feeding device 1a, the shearing device 1b and the banding device 1c in this embodiment are all prior arts and will not be elaborated here. The banding slot 2b in this embodiment is located between two adjacent inner support blocks 3. Therefore, after the edge banding strips are wound, the banding slot 2b can extend to the outer and inner circles of the edge banding strip roll, facilitating the banding of the banding device 1c through the banding slot 2b in time after winding, keeping the coil in a fixed shape during unloading and transportation, avoiding loosening and deformation, and ensuring the packaging quality. In this embodiment, the pushing block 4 cooperates with the linear drive unit 4a to drive the inner support blocks 3 to contract towards the axis of the turntable 2 while pushing the wound edge banding strip coil for unloading, releasing the tight connection between the coil and the inner support blocks 3, solving the problem of difficult unloading of traditional equipment and improving the unloading efficiency.

[0035] In order to achieve the purpose that the movement of the pushing block 4 along the axial direction of the turntable 2 can drive the inner support blocks 3 to move synchronously in the radial direction of the turntable 2, the following features are specifically set: The inner support block 3 is fan-shaped, the side walls of two adjacent inner support blocks 3 are parallel, a limiting block 3a is arranged on one side of the inner support block 3 facing the turntable 2, the limiting block 3a is inserted into an insertion hole 2c arranged on the turntable 2, the insertion hole 2c extends along the radial direction of the turntable 2, and a limiting strip 3b parallel to the axis of the turntable 2 is arranged at one end of the limiting block 3a away from the inner support block 3; the pushing block 4 is inserted into a sliding sleeve 2d arranged on the turntable 2 and matching the shape of the pushing block 4, a connecting strip 4b extending vertically downward is arranged at one end of the pushing block 4 away from the inner support block 3, and a limiting column 4b1 perpendicular to the axis of the turntable 2 and the axis of the sliding sleeve 2d is arranged at the bottom of the connecting strip 4b, and the limiting column 4b1 is slidably installed in a first limiting groove 3b2 arranged on the limiting strip 3b, the first limiting groove 3b2 extends along the length direction of the limiting strip 3b, and an inclined second limiting groove 3b3 is connected to one end of the first limiting groove 3b2 away from the inner support block 3, and one end of the second limiting groove 3b3 away from the inner support block 3 extends towards the direction close to the axis of the turntable 2.

[0036] In this embodiment, the inner support block 3 is inserted into the insertion hole 2c of the turntable 2 through the limiting block 3a and moves along the length direction of the insertion hole 2c, and the limiting strip 3b cooperates with the limiting column 4b1 on the pushing block 4. Under the normal working state, the limiting column 4b1 is located at the lowest end of the second limiting groove 3b3. At this time, the inner support block 3 is located at a position away from the axis of the turntable 2, providing support for the winding of the edge sealing strip. When the edge sealing strip is wound and bundled, the linear driving unit 4a drives the pushing block 4 to slide in the sliding sleeve 2d, so that the pushing block 4 moves along the axis of the turntable 2. As the pushing block 4 moves, the limiting column 4b1 slides in the second limiting groove 3b3 towards the first limiting groove 3b2. Since the horizontal height of the limiting column 4b1 remains unchanged, and the first limiting groove 3b2 is farther from the axis of the turntable 2 than the second limiting groove 3b3, the movement of the limiting column 4b1 drives the inner support block 3 to move towards the axis of the turntable 2 in the insertion hole 2c, realizing the contraction of the inner support block 3, so that the material roll is separated from the inner support block 3, facilitating the feeding of the material roll. In this embodiment, through the cooperation of the limiting column 4b1 with the first limiting groove 3b2 and the second limiting groove 3b3, the linear movement of the pushing block 4 along the axis of the turntable 2 is accurately converted into the synchronous movement of the inner support block 3 along the radial direction of the turntable 2, ensuring the accuracy and consistency of the contraction action of the inner support block 3, and providing a reliable guarantee for the smooth feeding of the material roll. Since the first limiting groove 3b2 extends along the length direction of the limiting strip 3b, the pushing block 4 can continue to move after the inner support blocks 3 are attached to each other to push the edge sealing strip material roll away from the turntable 2.

[0037] In order to ensure that the linear driving unit 4a can ensure that the pushing block 4 can move along the axis of the turntable 2 on the premise of following the rotation of the turntable 2, the following features are specifically set: The linear drive unit 4a includes a first linear driver 4a1 fixedly installed on the frame 1. The working end of the first linear driver 4a1 moves along the axis direction of the turntable 2. A moving seat 4a2 is fixedly installed on the working end of the first linear driver 4a1. A rotating ring 4a3 is rotatably installed on the moving seat 4a2. The axis of the rotating ring 4a3 is on the same straight line as the axis of the turntable 2. The pushing block 4 is provided with a connecting rod 4c extending along the axis direction of the turntable 2. One end of the connecting rod 4c away from the pushing block 4 is connected to the rotating ring 4a3.

[0038] In this embodiment, when the turntable 2 rotates to wind the edge banding, the pushing block 4 is connected to the rotating ring 4a3 through the connecting rod 4c and rotates synchronously with the turntable 2. At this time, the rotating ring 4a3 rotates freely on the moving seat 4a2, and the moving seat 4a2 remains stationary under the action of the first linear driver 4a1. When it is necessary for the pushing block 4 to move along the axis direction of the turntable 2, the first linear driver 4a1 is started, and its working end drives the moving seat 4a2 to move along the axis direction of the turntable 2. Further, it drives the connection between the rotating ring 4a3 and the pushing block 4 to move along the axis direction of the turntable 2. The first linear driver 4a1 can be a linear cylinder or an electric push rod, etc. Through the rotational connection between the rotating ring 4a3 and the moving seat 4a2, the function that the pushing block 4 needs to rotate with the turntable 2 and also move along the axis is realized.

[0039] In order to ensure that when the limit post 4b1 moves back and forth in the first limit groove 3b2 and the second limit groove 3b3, the inner support block 3 can move reciprocally along the insertion hole 2c, the following features are specifically set: The linear distance between the lowest ends of the first limit groove 3b2 and the second limit groove 3b3 is not greater than the difference between the length of the insertion hole 2c and the length of the limit block 3a.

[0040] In this embodiment, the linear distance between the lowest ends of the first limit groove 3b2 and the second limit groove 3b3 is not greater than the difference between the length of the insertion hole 2c and the length of the limit block 3a. Thus, it can be ensured that the moving range of the limit post 4b1 driving the inner support block 3 is always smaller than the moving range of the limit block 3a of the inner support block 3 in the insertion hole 2c, ensuring the movement of the inner support block 3.

[0041] In order to realize the rotation of the turntable 2, the following features are specifically set: The rotation drive unit 2a includes a rotation driver 2a1 fixedly installed on the frame 1. The working end of the rotation driver 2a1 is drivingly connected to a rotating shaft 2a2. The turntable 2 is coaxially installed on the rotating shaft 2a2.

[0042] The rotation driver 2a1 in this embodiment can be a servo motor.

[0043] In order to ensure that when the inner support block 3 is adjusted by the limit post 4b1, it only maintains the movement in the radial direction of the turntable 2, the following features are specifically set: The limiting strip 3b is provided with a guiding hole 3b1 extending parallel to the length direction of the insertion hole 2c, and a guiding rod 2e provided on the side of the turntable 2 away from the inner supporting block 3 is inserted into the guiding hole 3b1.

[0044] In this embodiment, through the guiding of the limiting strip 3b by the guiding rod 2e in the guiding hole 3b1 and the limiting of the limiting block 3a in the insertion hole 2c, it is ensured that the inner supporting block 3 can only move radially on the turntable 2.

[0045] In order to make the pushing block 4 keep flush with the surface of the turntable 2 when the edge banding strip is wound, the following features are specifically set: On both sides of one end of the pushing block 4 facing the inner supporting block 3, there are protruding positioning bumps 4d. On the side of the sliding sleeve 2d of the turntable 2 facing the inner supporting block 3, there is a positioning groove 2d1. The positioning groove 2d1 extends along the axis direction of the turntable 2 and has the same length as the length of the positioning bump 4d.

[0046] In this embodiment, the pushing block 4 slides in the sliding sleeve 2d of the turntable 2, and the positioning bump 4d is located in the positioning groove 2d1. Since the positioning groove 2d1 extends along the axis direction of the turntable 2 and has the same length as the length of the positioning bump 4d, when the pushing block 4 is in the initial position, the positioning bump 4d fits against the inner wall of one end of the positioning groove 2d1 away from the inner supporting block 3. At this time, the surface of the pushing block 4 is flush with the surface of the turntable 2. This can prevent interference between the edge banding strip and the pushing block 4 during the winding process, ensure that the edge banding strip can be wound evenly and tightly around the outside of the inner supporting block 3, and avoid unevenness or winding misalignment on the surface of the material roll caused by the protrusion of the pushing block 4. When the pushing block 4 is reset, the positioning bump 4d slides reversely along the positioning groove 2d1, making the surface of the pushing block 4 flush with the surface of the turntable 2 again.

[0047] In order to enable the rotary drive unit 2a to drive the turntable 2 to intermittently rotate to a position where the banding slot 2b is aligned with the working position of the banding device 1c, the following features are specifically set: On the side of the rotating ring 4a3 away from the turntable 2, there are positioning insertion holes 4a4 with the same number as the banding slots 2b. The positioning insertion holes 4a4 are evenly distributed around the axis of the rotating ring 4a3 at equal angles, and the axes of the positioning insertion holes 4a4 are parallel to the axis of the turntable 2; on the frame 1, there is a second linear driver 1d. The working end of the second linear driver 1d moves along the axis direction of the turntable 2. An elastic positioning rod 1d1 is fixedly installed on the working end of the second linear driver 1d. The elastic positioning rod 1d1 is coaxially installed in the sleeve 1d2. A spring 1d3 that elastically connects the elastic positioning rod 1d1 is arranged in the sleeve 1d2. A distance measuring sensor 1d4 is arranged in the sleeve 1d2. The distance measuring sensor 1d4 is signal-connected to the rotary drive unit 2a and the banding device 1c through a controller. When the elastic positioning rod 1d1 is inserted into the positioning insertion hole 4a4, one of the banding slots 2b is aligned with the working end of the banding device 1c.

[0048] In this embodiment, the rotary drive unit 2a drives the turntable 2 to rotate, and the rotary ring 4a3 rotates synchronously with the turntable 2. The positioning jacks 4a4 evenly distributed at equal angles on the side of the rotary ring 4a3 away from the turntable 2 also rotate accordingly. When the winding operation is carried out, the second linear driver 1d on the frame 1 drives the elastic positioning rod 1d1 away from the surface of the rotary ring 4a3. After the winding is completed, the second linear driver 1d drives the elastic positioning rod 1d1 to fit the surface of the rotary ring 4a3, and the elastic positioning rod 1d1 fits the surface of the rotary ring 4a3 and compresses the spring 1d3 into the sleeve 1d2. When a certain strap slot 2b on the turntable 2 aligns with the working end of the strapping device 1c, the elastic positioning rod 1d1 is inserted into one of the positioning jacks 4a4. The distance sensor 1d4 in the sleeve 1d2 detects the change in the distance between the elastic positioning rod 1d1 and the positioning jack 4a4 and transmits the signal to the controller. The controller controls the rotary drive unit 2a to stop moving and starts the strapping device 1c to strap the material roll. After the strapping is completed, the controller instructs the rotary drive unit 2a to restart, and the turntable 2 continues to rotate to enter the next working cycle. The second linear driver 1d can be a linear cylinder or an electric push rod, etc. In this embodiment, through the cooperation of the elastic positioning rod 1d1 and the positioning jack 4a4 and the real-time monitoring of the distance sensor 1d4, it is ensured that the strap slot 2b is accurately aligned with the working end of the strapping device 1c, avoiding strapping deviation and ensuring that the material roll is strapped tightly and neatly.

[0049] In order to enable the rotation of the rotary ring 4a3 to directly drive the elastic positioning rod 1d1 to disengage from the positioning jack 4a4, the following features are specifically set: The top end of the elastic positioning rod 1d1 is a round head, and the radius of the round head at the top end of the elastic positioning rod 1d1 is greater than the depth of the positioning jack 4a4.

[0050] In this embodiment, since the top end of the elastic positioning rod 1d1 is a round head and the radius of the round head at the top end is greater than the depth of the positioning jack 4a4, when the rotary ring 4a3 rotates, the hole wall of the positioning jack 4a4 contacts the side surface of the round head of the elastic positioning rod 1d1 and generates a force. This force pushes the elastic positioning rod 1d1 to overcome the elastic force of the spring 1d3 and move along the sleeve 1d2 in the direction away from the rotary ring 4a3, so that the elastic positioning rod 1d1 directly disengages from the positioning jack 4a4. The turntable 2 continues to rotate and can directly enter the position for the next bundling of the edge sealing strip.

[0051] In order to facilitate the fixing of the end of the edge sealing strip, the following features are specifically set: A clamping groove 3c for fixing the end of the edge sealing strip is provided on the side of the inner support block 3 away from the axis of the turntable 2.

[0052] When the edge sealing strip is wound in this embodiment, the end of the edge sealing strip can be inserted into the clamping groove 3c on the outer wall of one of the inner support blocks 3, which is convenient for ensuring the smooth progress of the winding.

[0053] Working principle: The feeding device 1a conveys the edge banding to the turntable 2, and the rotational drive unit 2a drives the turntable 2 to rotate, so that the edge banding is wound around the outside of the inner support blocks 3 which are evenly distributed at equal angles around the axis of the turntable 2. When the edge banding is wound to the set length or number of turns, the banding device 1c bundles the wound edge banding through the banding slot 2b which is located between two adjacent inner support blocks 3 and extends radially along the turntable 2. After the bundling is completed, the shearing device 1b cuts off the edge banding. Subsequently, the linear drive unit 4a drives the pushing block 4 to move axially along the turntable 2 towards the side of the turntable 2 where the inner support blocks 3 are provided. While the pushing block 4 moves, it drives all the inner support blocks 3 to move synchronously towards the axis of the turntable 2, reducing the connection tightness between the material roll and the inner support blocks 3, facilitating the unloading of the material roll from the turntable 2, and completing the entire packing process.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
