Description

Technical Field

[0001] This utility model relates to the technical field of door frame production, and in particular to a door frame packaging support device. Background Technology

[0002] In today's booming construction and home decoration industry, door frames, as a fundamental structural component for building entrances and interior space partitions, bear the heavy responsibility of supporting the door, ensuring the airtightness of the space, providing sound insulation and noise reduction, and maintaining the overall aesthetic harmony of the building. From the production factory to the construction site, or during long-distance transportation across regions and countries, door frames undergo multiple handling and storage processes, making them highly susceptible to physical damage. This underscores the increasing importance of door frame packaging. In the process of packaging door frames, companies often use stretch wrapping machines to wrap the door frames. For example, Chinese patent document CN117204300B discloses a stretch wrapping machine. The stretch wrapping machine includes a base frame, a threaded rod rotatably mounted on the upper front edge of the base frame, a guide rod fixedly mounted on the upper rear edge of the base frame, a rear frame fitted to the outer surface of the guide rod, a threaded sleeve screwed onto the outer surface of the threaded rod, a front frame fixedly mounted on the upper end of the threaded sleeve, and a wrapping table fixedly mounted on the upper ends of the front and rear frames. A wrapping component is mounted on one side of the wrapping table, and an arc-shaped oscillating spray component is mounted on the other side of the wrapping table. The wrapping component is connected to the arc-shaped oscillating spray component. A flipping support is mounted on the inner front end of the base frame, and a top seat is fixedly mounted on the rear end of the front frame. This ensures the normal operation of the wrapping process.

[0003] However, existing stretch wrapping machines have the following shortcomings in actual use: During the door frame packaging process, the worker places the door frame on the workbench used to support the door frame and inserts one of the frame strips into the wrapping material. The wrapping material will rotate around the frame strip as the axis so that the packaging material on the stretch wrapping machine wraps around the frame. However, since the door frame is a frame connected end to end, the wrapping material needs to stop wrapping when it encounters a support position and then move the wrapping material around the support position before it can continue to work. As a result, the quality and efficiency of door frame packaging are low. In view of this, the door frame packaging support device of this application is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a door frame packaging support device that can automatically move away from the door frame support position as the winding component moves, thereby improving packaging quality and efficiency.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A door frame packaging support device includes a winding member for wrapping door frames, the winding member including a winding head and a gantry frame, the winding head being disposed on the gantry frame, and further comprising:

[0007] A pusher plate, wherein the pusher plate is disposed on the winding head; and

[0008] A support assembly includes a frame and multiple support members, each of which is disposed on the frame and spaced apart along the perimeter of the frame. All support members collectively support a door frame. Each support member includes a base, a stop block, and a return spring. The base is disposed on the frame, and the stop block is rotatably disposed on the base. The stop block supports the door frame. A gantry frame is slidably disposed on the frame. When the gantry frame moves the winding head closer to the stop block, the winding head moves the push plate to push the stop block away from the door frame, so that the winding head can wrap and package the door frame. The return spring is connected to both the base and the stop block, and pulls the stop block to rotate closer to the door frame.

[0009] Optionally, the support member further includes two inclined clamping blocks. The stop block has a top groove. Both inclined clamping blocks are rotatably mounted on the stop block and are located in the top groove. The two inclined clamping blocks are used to clamp the door frame together.

[0010] Optionally, the support member further includes a top locking member, which is inserted through the stop block. One end of the top locking member extends from one side of the stop block to the other side of the stop block, and the other end of the top locking member extends from one side of the stop block into the top groove. One end of the top locking member abuts against the push plate, and the other end of the top locking member abuts against the two inclined clamping blocks.

[0011] Optionally, the top locking component includes a contact plate, a sliding column, a top block, and a push spring. The sliding column passes through the stop block and extends from opposite sides of the stop block. The contact plate is located at one end of the sliding column, and the top block is located at the other end of the sliding column. The push spring is sleeved on the sliding column and pushes the contact plate and the stop block respectively, so that the end of the top block away from the sliding column extends into the top groove.

[0012] Optionally, the top block has an arc-shaped portion located at the end of the top block away from the sliding column, and the arc-shaped portion abuts against the two inclined clamping blocks.

[0013] Optionally, the inclined clamping block has an inclined surface located on one side of the inclined clamping block near the top block, and the inclined surface abuts against the two arc-shaped portions.

[0014] Optionally, the stop block is provided with a limiting angle, which is located at the end of the stop block near the base.

[0015] Optionally, the frame includes a bed frame, a support plate, and several lifting cylinders. The support plate slides up and down on the bed frame. Each of the support components is disposed on the support plate. Each of the lifting cylinders is disposed on the bed frame, and the output end of each of the lifting cylinders is connected to the support plate. The lifting cylinders together drive the support plate to move up and down.

[0016] Optionally, the frame further includes two slide rails, which are respectively disposed at opposite ends of the bed frame, and the two ends of the gantry frame are slidably connected to the two slide rails respectively.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] The door frame packaging support device of this utility model can push open any one of the blocks supporting the door frame by a push plate without stopping the winding head, so that while each block supports the door frame, the winding head can continuously package the frame, thereby improving the packaging quality and efficiency of the door frame.

Detailed Implementation

[0030] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0033] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] like Figures 1 to 2 In one embodiment, a door frame packaging support device 1 includes a winding component for wrapping the door frame. The winding component includes a winding head 30 and a gantry frame 40. The winding head 30 is disposed on the gantry frame 40. It also includes a push plate 10 and a support assembly 20. The push plate 10 is disposed on the winding head 30. The support assembly 20 includes a frame 21 and multiple support members 22. Each support member 22 is disposed on the frame 21 and is spaced apart along the perimeter of the frame 21. All support members 22 collectively support the door frame. Each support member 22 includes a base 2. 21. Stop 222 and reset spring 223. Base 221 is set on frame 21. Stop 222 is rotatably set on base 221. Stop 222 is used to support door frame. Gantry 40 is slidably set on frame 21. When gantry 40 drives winding head 30 to approach stop 222, winding head 30 drives push plate 10 to push stop 222 away from door frame so that winding head 30 can wrap door frame. Reset spring 223 is connected to base 221 and stop 222 respectively. Reset spring 223 pulls stop 222 to rotate and approach door frame.

[0035] It should be noted that the gantry frame 40 includes a crossbar and two uprights. One end of each upright is slidably connected to the opposite sides of the frame 21, and the ends of the uprights away from the frame 21 are connected to both ends of the crossbar. The winding component includes a connecting plate, a winding head 30, and a rotating motor. The connecting plate is slidably mounted on the crossbar, the rotating motor is mounted on the connecting plate, and the winding head 30 is mounted on the output shaft of the rotating motor. This allows the gantry frame 40 to drive the winding head 30 to slide along the door frame. For example, the gantry frame 40 drives the winding head 30 to slide along the long side of the door frame. When the winding head 30 slides to the intersection of the long side and the short side of the door frame, the rotating motor drives the winding head 30 to rotate 90 degrees, so that the winding head 30 moves from one end of the long side of the door frame to one end of the short side. Then, the connecting plate drives the winding head 30 to slide along the short side of the door frame. In this way, the winding head 30 can slide along all four sides of the door frame, thereby enabling the winding head 30 to continuously wrap and package door frames that are connected end to end. Furthermore, one end of the push plate 10 is located on one side of the winding head 30 in the forward direction, and one end of the push plate 10 extends in the forward direction of the winding head 30, while the other end of the push plate 10 faces each support member 22 on the frame 21, and the end of the push plate 10 away from the winding head 30 is located between any two support members 22.

[0036] It should be noted that the frame 21 has a rectangular structure, and its length and width are both greater than those of the door frame. Each support member 22 is disposed on one surface of the frame 21, and the support members 22 are spaced apart along the four directions of the frame 21, so that each support member 22 can collectively support the four sides of the door frame. It should be noted that at least two support members 22 support each of the four sides of the door frame. Furthermore, the base 221 is disposed on the frame 21, and one end of the stop block 222 is rotatably connected to one side of the base 221, allowing the stop block 222 to rotate laterally relative to the base 221. The end of the stop block 222 away from the base 221 abuts against the door frame, thus enabling the ends of each stop block 222 away from the base 221 to collectively support the four sides of the door frame. Further, for ease of description, the side of the baffle closer to the winding head 30 is designated as the first side 2221, and the side of the baffle away from the winding head 30 is designated as the second side 2222. One end of the reset spring 223 is connected to the first side 2221 of the stop block 222, and the other end of the reset spring 223 is connected to one side of the base 221. The reset spring 223 is located on the same side of the stop block 222 and the base 221. Thus, when the gantry frame 40 drives the winding member to slide relative to the frame 21, the winding head 30 drives the push plate 10 to push the first side 2221 of the stop block 222, so that the stop block 222 rotates laterally away from the door frame. Since the winding head 30 rotates around the frame strip of the door frame, when the stop block 222 moves away from the door frame, the winding head 30 can continue to rotate around the frame as the axis, so that the packaging material can be continuously wound on the frame strip. When the push plate 10 disengages from the stop block 222, the reset spring 223 will pull the stop block 222 to rotate laterally closer to the door frame, so that the stop block 222 can support the door frame again. Furthermore, since multiple support members 22 are spaced apart around the frame 21 and multiple support members 22 jointly support the door frame, during the movement of the push plate 10, only one support member 22 can be pushed away from the door frame at a time. In this way, the other support members 22 can continue to support the door frame. During this process, the wrapping head 30 does not need to stop working and can continuously package the frame, thereby improving the packaging quality and efficiency of the door frame.

[0037] As shown in the figure, in one embodiment, the support member 22 further includes two inclined clamping blocks 224. The stop block 222 has a top groove 2223. The two inclined clamping blocks 224 are rotatably mounted on the stop block 222, and both inclined clamping blocks 224 are located in the top groove 2223. The two inclined clamping blocks 224 are used to clamp the door frame together.

[0038] It should be noted that a top groove 2223 is provided on the end of the stop block 222 away from the base 221. The opening of the top groove 2223 faces one side of the door frame, and one inner side of the top groove 2223 communicates with the second side 2222 on the stop block 222. Furthermore, both inclined clamping blocks 224 are rotatably disposed within the top groove 2223, allowing them to extend from both ends of the top groove 2223 to form an angle, thereby clamping the door frame together to prevent the door frame from shifting during packaging. Furthermore, each support member 22 is distributed around the frame 21, and each support member 22 abuts against the four sides of the door frame, forming a right angle between the inclined clamping blocks 224 clamping the long side of the door frame and the inclined clamping blocks 224 clamping the short side of the door frame. This prevents the door frame from moving towards either the long or short side. Since there are at least two support members 22 on the long and short sides of the door frame, when the winding head 30 pushes open the stop block 222 on one of the support members 22 on the short side of the door frame, there is another support member 22 on the short side of the door frame to support the door frame, and the two inclined clamping blocks 224 on the remaining support member 22 can clamp the door frame to prevent the door frame from sliding out from this side of the short side.

[0039] like Figures 3 to 5 As shown, in one embodiment, the support assembly 20 further includes a top locking member 23, which passes through the stop block 222. One end of the top locking member 23 extends from one side of the stop block 222 to the other side of the stop block 222, and the other end of the top locking member 23 extends from one side of the stop block 222 into the top groove 2223. One end of the top locking member 23 abuts against the push plate 10, and the other end of the top locking member 23 abuts against the two inclined clamping blocks 224.

[0040] It should be noted that one end of the top locking member 23 extends from the second side 2222 of the stop block 222 to the first side 2221 of the stop block 222, while the other end of the top locking member 23 extends from the second side 2222 of the stop block 222 into the top groove 2223 to push the two inclined clamping blocks 224, so that the two inclined clamping blocks 224 extend from both ends of the top groove 2223 at the same time to clamp the door frame together.

[0041] like Figure 5 , Figure 7 As shown, in one embodiment, the top locking member 23 includes a contact plate 231, a sliding column 232, a top block 233, and a push spring 234. The sliding column 232 passes through the stop block 222 and extends from the opposite sides of the stop block 222. The contact plate 231 is disposed at one end of the sliding column 232, and the top block 233 is disposed at the other end of the sliding column 232. The push spring 234 is sleeved on the sliding column 232 and pushes the contact plate 231 and the stop block 222 respectively, so that the end of the top block 233 away from the sliding column 232 extends into the top groove 2223.

[0042] It should be noted that at least two sliding pillars 232 are provided. Both sliding pillars 232 extend from the second side 2222 to the first side 2221. The end of each sliding pillar 232 extending from the first side 2221 is connected to the touch plate 231. The end of each sliding pillar 232 located on the second side 2222 is connected to one end of the top block 233. The end of the top block 233 away from the two sliding pillars 232 extends into the top groove 2223 to push the two inclined clamping blocks 224. Furthermore, the number of push springs 234 corresponds one-to-one with the number of sliding columns 232. The two push springs 234 are respectively sleeved on the two sliding columns 232, and the two push springs 234 are located between the contact plate 231 and the stop block 222. The push springs 234 push the contact plate 231 and the stop block 222 respectively, so that the contact plate 231 drives the top block 233 to extend into the top groove 2223 through the two sliding columns 232 and abut against the two inclined clamping blocks 224, thereby causing the two inclined clamping blocks 224 to extend out from the top groove 2223. Furthermore, when the winding head 30 drives the push plate 10 to slide close to the touch plate 231, the push plate 10 first contacts the touch plate 231, and the push plate 10 first pushes the touch plate 231 to compress the push spring 234, so that the touch plate 231 drives the top block 233 to slide out from the top groove 2223, thereby causing the two inclined clamping blocks 224 to retract into the top groove 2223 to release the door frame. At this time, the door frame is laid flat on the stop block 222. When the push plate 10 pushes the touch plate 231 to contact the stop block 222, the push plate 10 drives the touch plate 231 to push the stop block 222, and the stop block 222 can move laterally away from the door, thereby enabling the winding head 30 to wrap and package the door frame.

[0043] like Figure 7 As shown, in one embodiment, the top block 233 has an arc-shaped portion 2331, which is located on the end of the top block 233 away from the sliding column 232, and the arc-shaped portion 2331 abuts against the two inclined clamping blocks 224.

[0044] It should be noted that an arc-shaped portion 2331 is provided on one end of the top block 233 that extends into the top groove 2223, and the arc-shaped portion 2331 faces upward, so that the arc-shaped portion 2331 and the end of the two inclined clamping blocks 224 that pushes the door frame away at the same time, thereby causing the two inclined clamping blocks 224 to extend at the same time to clamp the door frame together.

[0045] like Figure 8 As shown, in one embodiment, the inclined clamping block 224 has an inclined surface 2241, which is located on one side of the inclined clamping block 224 near the top block 233. The inclined surface 2241 abuts against the two arc-shaped portions 2331.

[0046] It should be noted that one end of the inclined clamping block 224 is rotatably disposed within the top groove 2223, while the other end of the inclined clamping block 224 has an arc-shaped structure, allowing the inclined clamping block 224 to rotatably extend out of or retract into the top groove 2223. Furthermore, the inclined clamping block 224 has an inclined surface 2241 on the side facing the second side 2222, which abuts against the arc-shaped portion 2331 on the top block 233. Thus, when the top block 233 extends into the top groove 2223, the inclined surface 2241 extends upward along the arc-shaped portion 2331.

[0047] like Figures 5 to 6 As shown, in one embodiment, a limiting angle 2224 is provided on the stop 222, and the limiting angle 2224 is located on the end of the stop 222 near the base 221.

[0048] It should be noted that the limiting angle 2224 is located at the end of the stop block 222 near the base 221, and the limiting angle 2224 is located on the first side 2221 of the stop block 222, so that the baffle can only rotate away from the door frame relative to the base 221 towards the second side 2222. When the return spring 223 pulls the stop block 222 closer to the door frame, it allows the door frame to stop directly below the door frame to support it.

[0049] like Figure 1 As shown, in one embodiment, the frame 21 includes a bed frame 211, a support plate 212, and a plurality of lifting cylinders 213. The support plate 212 slides up and down on the bed frame 211. Each support member 22 is disposed on the support plate 212. Each lifting cylinder 213 is disposed on the bed frame 211, and the output end of each lifting cylinder 213 is connected to the support plate 212. Each lifting cylinder 213 together drives the support plate 212 to move up and down.

[0050] It should be noted that the support plate 212 is provided with several guide posts 2121, and the end of each guide post 2121 away from the support plate 212 passes through the bed frame 211, so that the support plate 212 can slide up and down relative to the bed frame 211. Furthermore, each lifting cylinder 213 is spaced apart on the bed frame 211, and the output end of each lifting cylinder 213 is connected to the support plate 212, so that each lifting cylinder 213 together drives the support plate 212 to move up and down.

[0051] like Figure 1 As shown, in one embodiment, the frame 21 further includes two slide rails 214, which are respectively disposed at opposite ends of the bed frame 211, and the two ends of the gantry frame 40 are slidably connected to the two slide rails 214 respectively.

[0052] It should be noted that the two slide rails 214 are respectively set on the two long sides of the bed frame 211, and the two uprights on the gantry frame 40 are slidably connected to the two slide rails 214 respectively, so that the gantry frame 40 can drive the winding head 30 to slide above the support plate 212, thereby wrapping the door frame.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
