Description

Technical Field

[0001] This utility model relates to the field of corner bracket installation, and in particular to a corner bracket hopper. Background Technology

[0002] As door and window structures continue to evolve, each end of the profiles needs to be fitted with two different types of corner brackets, which necessitates a corner bracket storage bin capable of storing various types of corner brackets to meet the needs of assembling corner brackets.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN222386286U provides a corner code feeding unit, including a material rack with at least two storage slots. Multiple storage slots are inclinedly arranged on the material rack. A baffle is provided on the material rack near the lower end of the storage slots. The baffle includes a connecting part and a blocking part. The connecting part is connected to the material rack, and the blocking part is inclinedly arranged above the connecting part, abutting against a portion of the corner code end face. To prevent adjacent corner codes from being carried out during discharge, an anti-slip plate is provided on the material rack, located above the lower end of the corresponding storage slot. Parallel to the storage trough, and to allow adjustment of the height and position of the anti-slip plate, the material rack includes a mounting rod. An adjusting plate is movably mounted on the mounting plate, with the direction of movement of the adjusting plate perpendicular to the length direction of the mounting rod. A straight groove is provided on the adjusting plate, with the length direction of the straight groove being the same as the direction of movement of the adjusting plate. A locking bolt passes through the straight groove and is connected to the mounting rod. Two adjusting rods are provided through the adjusting plate, and two adjusting nuts are provided on the adjusting rods. The two adjusting nuts are located on the upper and lower sides of the adjusting plate, respectively. An anti-slip plate is provided at the lower part of the adjusting rod.

[0004] While the above solution can accommodate various types of corner brackets, the height and front-to-back position of the anti-stripping plate need to be adjusted as the type of corner bracket changes. This requires rotating at least several nuts between the adjustment plate and the mounting plate, as well as two nuts on the locking bolt, resulting in low adjustment efficiency. Utility Model Content

[0005] In order to solve the technical problem of low adjustment efficiency of the anti-slip plate in the corner code hopper in the prior art, the present invention provides a corner code hopper that can improve the adjustment efficiency of the anti-slip plate.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a corner code hopper, including a material rack, on which at least two storage troughs and at least two anti-slip plates are provided, and also includes an adjustment unit, which is arranged one-to-one with the storage troughs. The adjustment unit includes: a support rod, which is connected to the material rack and is arranged parallel to the storage trough and above the corresponding storage trough; and an adjustment seat, which is movably arranged below the support rod by a lifting assembly. The moving direction of the adjustment seat is perpendicular to the length direction of the support rod. A fixing ring assembly is provided on the adjustment seat, and an adjustment rod is inserted through the fixing ring assembly. The adjustment rod is arranged parallel to the anti-slip plates, and one end of the adjustment rod is connected to the anti-slip plates. The adjustment rod can move along its own axial direction and can be locked by the fixing ring assembly.

[0007] This invention enables quick locking and unlocking of the adjusting rod through a fixing ring assembly, and adjusts the front and rear positions of the anti-slip plate by driving the adjusting rod. Compared with the prior art, which adjusts the position by unlocking multiple nuts, the workload is greatly reduced and the efficiency is higher. Furthermore, under the limiting effect of the fixing ring assembly, the adjusting rod can only move along its own axis. Compared with the prior art, it can ensure that the relative position of the anti-slip plate and the storage tank remains unchanged before and after adjustment along the arrangement direction of the storage tank, thus improving the adjustment accuracy.

[0008] Furthermore, the anti-slip plate is located below the adjusting seat, the adjusting rod is connected to the end of the anti-slip plate through a connecting plate, and the anti-slip plate and the adjusting seat are movably connected through a guide rail assembly.

[0009] This utility model connects the anti-slip plate and the adjustment seat through a guide rail, which can prevent the anti-slip plate from sagging under its own weight and failing to accurately limit the adjacent corner codes.

[0010] Furthermore, the lifting assembly includes a limiting post and an adjusting block. The limiting post is vertically mounted on the support rod, and a limiting shaft is vertically mounted at the lower end of the limiting post. The adjusting block is movably mounted on the upper surface of the adjusting seat. The adjusting block is provided with a guide groove, which is a straight slot hole. The guide groove is inclined, and the limiting shaft extends into the guide groove and can move along the guide groove. The adjusting block is provided with a driving rod, which is parallel to the adjusting rod. The adjusting seat is provided with a second fixing ring assembly, which can limit the position of the driving rod. The second fixing ring assembly has the same structure as the first fixing ring assembly and is mounted on the adjusting seat.

[0011] This invention achieves quick unlocking and locking of the drive rod through the fixed ring assembly two, and adjusts the height of the anti-slip plate by moving the drive rod. Compared with the prior art, which unlocks multiple nuts, this invention further improves the adjustment efficiency of the anti-slip plate and can always maintain the parallel relationship between the anti-slip plate and the storage trough, ensuring that the anti-slip plate reliably performs its anti-slip function before and after adjustment.

[0012] Furthermore, the adjusting block has a wedge-shaped structure, a guide plate is provided on the inclined surface of the adjusting block, a guide groove is provided on the guide plate, the length direction of the guide groove is parallel to the length direction of the inclined surface, and a roller is rotatably provided on the limiting shaft, the outer circumferential surface of the roller rolls and rubs against the inclined surface of the adjusting block.

[0013] This invention, by setting a wedge-shaped adjusting block and rollers, ensures that the center of the limiting shaft always moves along the center line of the guide groove, eliminating the influence of the gap between the limiting shaft and the guide groove on the adjustment accuracy and improving the adjustment accuracy.

[0014] Furthermore, a guide rod is vertically arranged on the adjustment seat, the guide rod passing through the support rod and being able to move axially.

[0015] Furthermore, it also includes a base plate, one end of the material rack is rotatably mounted on the base plate, and a lifting cylinder is provided between the other end of the material rack and the base plate. The cylinder body of the lifting cylinder is hinged to the base plate, and the piston rod of the lifting cylinder is hinged to the material rack.

[0016] This invention, by incorporating a lifting cylinder, ensures that the corner brackets are placed horizontally by the operator, thereby reducing the height of the material rack and the labor intensity of placing the corner brackets.

[0017] Furthermore, a support column is also provided on the base plate, and a buffer pad is provided at the upper end of the support column.

[0018] This utility model can buffer the impact between the material rack and the support column when the material rack is placed, and avoid the impact vibration that could cause the corner brackets that have not been discharged to tip over.

[0019] Furthermore, two support frames are arranged opposite each other on the material rack along the length of the storage tank, the support frames straddle multiple storage tanks, and the two ends of the support rod are respectively connected to the corresponding support frame.

[0020] As can be seen from the above technical solutions, this utility model has the following advantages:

[0021] This utility model provides a corner code hopper. A first fixing ring assembly enables quick locking and unlocking of the adjusting rod, and the driving of the adjusting rod adjusts the front and rear positions of the anti-slip plate. Compared to existing technologies that use multiple nuts for position adjustment, this significantly reduces workload and increases efficiency. Furthermore, under the limiting effect of the first fixing ring assembly, the adjusting rod can only move along its own axial direction. Compared to existing technologies, this ensures that the relative positions of the anti-slip plate and the storage trough remain unchanged before and after adjustment, improving adjustment accuracy. The anti-slip plate and the adjusting seat are connected by a guide rail, preventing the anti-slip plate from sagging under its own weight and failing to accurately limit the adjacent corner codes. A second fixing ring assembly enables quick unlocking and locking of the driving rod, and the driving... The movement of the rod adjusts the height of the anti-slip plate, which, compared to existing technologies that rely on unlocking multiple nuts, significantly improves adjustment efficiency and maintains the parallel relationship between the anti-slip plate and the storage trough, ensuring reliable anti-slip function before and after adjustment. The wedge-shaped adjusting block and rollers ensure the center of the limiting shaft always moves along the center line of the guide groove, eliminating the impact of the gap between the limiting shaft and the guide groove on adjustment accuracy and improving overall accuracy. The lifting cylinder ensures the angle brackets are placed horizontally, reducing the height of the material rack and decreasing labor intensity. The buffer pads cushion the impact between the material rack and the support column when leveling, preventing impact vibrations that could cause undischarged angle brackets to tip over.

[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0030] like Figures 1 to 4As shown in the figure, this specific embodiment provides a corner code hopper, including a rack 1. The rack 1 is provided with at least two storage troughs 2 and at least two anti-slip plates 3. It also includes an adjustment unit, which is arranged one-to-one with each storage trough 2. That is, each storage trough 2 is provided with an anti-slip plate 3 and an adjustment unit. The adjustment unit includes a support rod 11 and an adjustment seat 8. The support rod 11 is connected to the rack 1 and its position does not change. The support rod 11 is arranged parallel to the storage trough 2 and is located above the corresponding storage trough 2. The adjustment seat 8 is movably arranged below the support rod 11 through a lifting assembly. The moving direction of the adjustment seat 8 is perpendicular to the length direction of the support rod 11. The adjustment seat 8 is provided with a fixing ring assembly 6, and an adjustment rod 5 is inserted through the fixing ring assembly 6. The adjustment rod 5 is connected to the anti-slip plate 3. Plates 3 are arranged in parallel. One end of the adjusting rod 5 is connected to the anti-slip plate 3. The adjusting rod 5 can move along its own axis and can be locked by the fixing ring assembly 6. The height position of the anti-slip plate 3 can be adjusted by the lifting assembly, and the front and rear position of the anti-slip plate 3 (along the corner code discharge direction) can be adjusted by the adjusting rod 5. The fixing ring assembly 6 adopts a handle-type fixing ring, which is a commercially available part. The fixing ring assembly 6 includes a positioning ring. The positioning ring has an open structure and is provided with a locking groove. The handle is set at the opening of the positioning ring by a bolt. After the handle is rotated at a certain angle, the bolt locks the opening of the positioning ring. The inner wall of the positioning ring can be tightly attached to the outer surface of the adjusting rod 5. After the handle is rotated in the opposite direction at a certain angle, the opening of the positioning ring separates, and the positioning ring is no longer tightly attached to the adjusting rod 5. Applying an axial force to the adjusting rod 5 can drive it to move. Other structures of the fixing ring assembly 6 are existing technologies and will not be described in detail.

[0031] This specific embodiment achieves rapid locking and unlocking of the adjusting rod 5 through the fixing ring assembly 6, and adjusts the front and rear positions of the anti-slip plate 3 by driving the axial direction of the adjusting rod 5. Compared with the prior art, which adjusts the position by unlocking multiple nuts, the workload is greatly reduced and the efficiency is higher. Furthermore, under the limiting action of the fixing ring assembly 6, the adjusting rod 5 can only move along its own axial direction. Compared with the prior art, it can ensure that the relative position of the anti-slip plate 3 and the storage tank 2 remains unchanged in the arrangement direction of the storage tank 2, thus ensuring the adjustment accuracy. It also eliminates the step of observing the positional relationship between the anti-slip plate 3 and the corresponding storage tank 2 in the arrangement direction of the storage tank 2 after adjustment, further improving the adjustment efficiency.

[0032] like Figure 3 and Figure 4As shown, further, the anti-stripping plate 3 is located below the adjusting seat 8, and the adjusting rod 5 is connected to the end of the anti-stripping plate 3 through the connecting plate 4. The anti-stripping plate 3 and the adjusting seat 8 are movably connected through a guide rail assembly. The guide rail assembly includes a guide rail and a slider. The guide rail is set on the lower surface of the adjusting seat 8, and the slider is set on the upper surface of the anti-stripping plate 3. By connecting the anti-stripping plate 3 and the adjusting seat 8 through the guide rail, the end of the anti-stripping plate 3 can be prevented from drooping under its own weight, and the relative position of the end of the anti-stripping plate 3 and the adjacent corner code can be prevented from changing, thus ensuring accurate positioning of the adjacent corner code.

[0033] The lifting assembly can drive the adjusting seat 8 to move in a direction perpendicular to the support rod 11 via a "motor + lead screw" method. The motor is mounted on the support rod 11, and the lead screw is rotatably mounted on the support rod 11 via bearings. The lead screw is connected to the adjusting seat 8 via a nut. To reduce manufacturing costs, such as... Figures 3 to 5 As shown, in this specific embodiment, the lifting assembly adopts the following structure: The lifting assembly includes a limiting post 12 and an adjusting block 17. The limiting post 12 is vertically mounted on the support rod 11 by bolts, and the relative positional relationship between the limiting post 12 and the support rod 11 is immutable. A limiting shaft 22 is vertically mounted at the lower end of the limiting post 12. The adjusting block 17 is movably mounted on the upper surface of the adjusting seat 8 via a guide rail assembly. The upper surface of the adjusting seat 8 is provided with a guide rail, and the lower surface of the adjusting block 17 is provided with a slider. A guide groove 21 is provided on the adjusting block 17. The guide groove 21 is a straight slot hole, and the guide groove 21 is inclined. In this specific embodiment, the front end of the guide groove 21 is inclined downward. The limiting shaft 22 extends into the guide groove 21, and the diameter of the limiting shaft 22 is smaller than the width of the guide groove 21. The limiting shaft 22 can move along the guide groove. 21. Movement: A drive rod 7 is provided on the adjustment block 17, and the drive rod 7 is arranged parallel to the adjustment rod 5. A second fixing ring assembly 9 is provided on the adjustment seat 8. The second fixing ring assembly 9 can limit the position of the drive rod 7. The second fixing ring assembly 9 has the same structure as the first fixing ring assembly 6. The locking ring of the second fixing ring assembly 9 is provided on the mounting plate on the adjustment seat 8. Furthermore, a guide rod 10 is vertically provided on the adjustment seat 8. The guide rod 10 passes through the guide sleeve on the support rod 11. The guide rod 10 and the guide sleeve can move axially. After unlocking, the drive rod 7 is pulled out, and the guide groove 21 and the limiting shaft 22 move relative to each other. Since the guide groove 21 is inclined, the distance between the lower surface of the adjustment seat 8 and the support rod 11 changes. The guide shaft moves along its own axis to adjust the height position of the anti-slip plate 3.

[0034] When the pull-out drive rod 7 moves, the limiting shaft 22 contacts the top of the guide groove 21. When the pull-out ends, due to the gap between the guide groove 21 and the limiting shaft 22, the adjusting seat 8 drops slightly under gravity. This slight drop affects the distance between the anti-slip plate 3 and the storage tank 2, causing the adjusted distance to be inaccurate. Figures 3 to 5 As shown, to solve this technical problem, the adjusting block 17 has a wedge-shaped structure. A guide plate 19 is provided on the inclined surface of the adjusting block 17, and a guide groove 21 is provided on the guide plate 19. The length direction of the guide groove 21 is parallel to the length direction of the inclined surface. A roller 18 is rotatably provided on the limiting shaft 22, and the outer circumferential surface of the roller 18 rolls and rubs against the inclined surface of the adjusting block 17. By setting the roller 18 and the inclined surface, the relative position of the limiting shaft 22 and the guide groove 21 will not change during and after the adjustment process, avoiding a slight descent of the adjusting seat 8 and improving the adjustment accuracy.

[0035] In the prior art, the material rack 1 is inclined. When the operator puts material in, their arm will continuously extend as the material rack 1 rises, which is physically demanding. Therefore, in this specific embodiment, as follows... Figure 1 and Figure 2 As shown, it also includes a base plate 14. One end of the material rack 1 is rotatably mounted on the base plate 14 via a hinge seat. A lifting cylinder 20 is provided between the other end of the material rack 1 and the base plate 14. The cylinder body of the lifting cylinder 20 is hinged to the base plate 14, and the piston rod of the lifting cylinder 20 is hinged to the material rack 1. When the operator needs to place the corner bracket, the lifting cylinder 20 retracts, and the material rack 1 returns to a horizontal state. After placement, the lifting cylinder 20 extends, and the material rack 1 tilts.

[0036] like Figure 1 and Figure 2 As shown, in order to enhance the support of the material rack 1, a support column 15 is also provided on the base plate 14; in order to avoid the material rack 1 from impacting the support column 15, a buffer is provided at the upper end of the support column 15. The buffer pad 16 is made of rubber. By setting the buffer pad 16, the impact generated between the material rack 1 and the support column 15 when it is placed flat can be buffered, avoiding impact vibration and causing the corner code that has not been discharged to tip over.

[0037] In this specific embodiment, the material rack 1 is a rectangular frame structure formed by profiles. Two support frames 13 are arranged opposite each other on the material rack 1 along the length direction of the storage tank 2. The support frames 13 straddle multiple storage tanks 2. The two ends of the support rod 11 are respectively connected to the lower surface of the corresponding support frame 13 by bolts.

[0038] In this specific embodiment, the corner code hopper also includes a baffle 23, which is configured one-to-one with the corresponding storage tank 2. The structures of the baffle 23 and the storage tank 2 are the same as those of the baffle 23 and the storage tank 2 in the Chinese utility model patent with authorization announcement number CN222386286U, which are prior art and will not be described in detail here. In this specific embodiment, five storage tanks 2, five anti-slip plates 3 and five sets of adjustment units are provided.

[0039] In this specific embodiment, the corner code adjacent to the baffle 23 is the first corner code, and "adjacent corner code" refers to the second corner code adjacent to the first corner code.

[0040] The process of adjusting the anti-slip plate 3 in this corner code hopper is as follows:

[0041] During adjustment, the material rack 1 is in an inclined state. Rotate the handle of the fixing ring assembly 2 9 to unlock the drive rod 7. Push or pull the drive rod 7 to make the adjusting seat 8 drive the anti-slip plate 3 to rise and fall. After reaching the set position, lock the handle. Then rotate the handle of the fixing ring assembly 1 6 to unlock the adjusting rod 5. Push or pull the adjusting rod 5 to make the anti-slip plate 3 move forward or backward. After moving into place, lock the handle.

[0042] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0043] 1. The adjusting rod 5 can be quickly locked and unlocked by the fixing ring assembly 6, and the front and rear positions of the anti-slip plate 3 can be adjusted by driving the adjusting rod 5. Compared with the existing technology, which adjusts the position by unlocking multiple nuts, the workload is greatly reduced and the efficiency is higher. Furthermore, under the limiting effect of the fixing ring assembly 6, the adjusting rod 5 can only move along its own axis. Compared with the existing technology, it can ensure that the relative position of the anti-slip plate 3 and the storage tank 2 remains unchanged before and after adjustment along the arrangement direction of the storage tank 2, thus improving the adjustment accuracy.

[0044] 2. The anti-slip plate 3 and the adjusting seat 8 are connected by a guide rail, which can prevent the anti-slip plate 3 from sagging under its own weight and failing to accurately limit the adjacent corner code;

[0045] 3. The drive rod 7 can be quickly unlocked and locked by the fixed ring assembly 2 9, and the height position of the anti-slip plate 3 can be adjusted by moving the drive rod 7. Compared with the prior art, which unlocks multiple nuts, the adjustment efficiency of the anti-slip plate 3 is further improved, and the parallel relationship between the anti-slip plate 3 and the storage tank 2 can always be maintained, ensuring that the anti-slip plate 3 can reliably play its anti-slip role before and after adjustment.

[0046] 4. By setting the wedge-shaped adjustment block 17 and roller 18, the center of the limiting shaft 22 is always moving on the center line of the guide groove 21, eliminating the influence of the gap between the limiting shaft 22 and the guide groove 21 on the adjustment accuracy and improving the adjustment accuracy;

[0047] 5. By setting up the lifting cylinder 20, the corner bracket can be kept in a horizontal position when the operator places it, thus reducing the height of the material rack 1 and reducing the labor intensity of placing the corner bracket;

[0048] 6. By setting the buffer pad 16, the impact generated between the material rack 1 and the support column 15 when the rack is placed can be buffered, avoiding impact vibration that could cause the corner brackets that have not been discharged to tip over.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
