Description

Technical Field

[0001] This utility model relates to the field of edge-oiling device technology, and in particular to an automatic edge-oiling machine head. Background Technology

[0002] In leather processing, the edges of the cut leather material are oiled. Traditional automatic edge oiling machines typically consist of two main parts: a machine head and a robotic arm. The robotic arm grips the leather material and moves it to the machine head for oiling. The robotic arm can plan the oiling path, so the machine head is usually fixed to the frame, and the robotic arm moves up and down, left and right, and back and forth. While this traditional method improves production efficiency to some extent, it still has some shortcomings. For example, the edges of leather are not necessarily straight; they may be uneven. Therefore, the robotic arm must plan a very precise oiling path during the oiling process; otherwise, uneven oiling can easily occur. Furthermore, positioning errors when the robotic arm grips the leather can lead to excessive collision force between the leather and the machine head, causing the leather to detach from the robotic arm. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automatic edge-oiling machine head that is simple in structure but can accommodate the clamping error of the robotic arm and irregular edge leather materials.

[0004] The technical solution of this utility model is as follows: An automatic edge-oiling machine head includes a base, a movable seat, and an edge-oiling box; the movable seat is mounted on the base, and the edge-oiling box is mounted on the movable seat; the movable seat is selectively connected to the base in either rotation or sliding, and is then movably connected to the edge-oiling box in the remaining manner, so that the edge-oiling box can slide along the base in one direction and rotate left and right; the movable seat is respectively connected to a first elastic element and a second elastic element; the first elastic element is used to reset the position of the movable seat in the sliding direction; the second elastic element is used to reset the position of the movable seat in the rotation direction.

[0005] Preferably, the bottom of the movable seat is provided with a sliding groove with an opening facing the base; the base is provided with a sliding platform that cooperates with the sliding groove.

[0006] Preferably, the movable seat is provided with a protruding pivot; the bottom of the oil edge box is pivotally connected to the pivot.

[0007] Preferably, the base is provided with a first mounting seat; one end of the first elastic element is mounted on the first mounting seat, and the other end is abutted and connected to the movable seat; the movable seat is provided with second mounting seats for mounting second elastic elements on the left and right sides respectively, and the oil edge box is provided with elastic element grooves at corresponding positions.

[0008] Preferably, the oiling box includes a box body and an oiling roller; the front end of the box body is provided with an oil collection groove; the oiling roller is rotatably installed in the oil collection groove;

[0009] Preferably, the oil collection trough is surrounded by a front low wall and a rear high wall; the front side of the oil roller faces the front low wall; the box body is provided with an oil inlet channel and an oil outlet channel; the openings of the oil inlet channel and the oil outlet channel leading to the oil collection trough are located on the rear high wall.

[0010] Preferably, a baffle plate is slidably disposed near the openings of the oil inlet channel and the oil outlet channel in the oil collection trough; the baffle plate can block the openings of the oil inlet channel and the oil outlet channel; the baffle plate is connected to a handle, and the handle extends out of the box body.

[0011] Preferably, the box body has an oil receiving groove formed outside the oil receiving groove; an oil leakage port is opened at the front end of the oil receiving groove.

[0012] Preferably, the box body further includes an upper cover, and one end of the oiling roller is rotatably connected to the upper cover.

[0013] Preferably, one end of the oiling roller extends out of the upper cover and is provided with a driven wheel; the driven wheel is connected to a driving wheel via a belt; the driving wheel is driven by a motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The edge-oiling box can slide and swing left and right relative to a fixed base in one direction, providing flexible self-adjustment. This allows the robotic arm to apply oil to the leather without requiring overly precise oiling paths, allowing for some error while ensuring even oiling. This is especially beneficial for leather with uneven edges, resulting in a significantly improved oiling yield.

[0016] 2. The edge oil box can control the speed of edge oil entry and exit by moving the baffle plate to block the opening of the oil inlet and outlet channels, thus making the amount of edge oil entry and exit adjustable.

[0017] 3. The edge paint rollers of the edge paint box can rotate freely or be driven by a motor. When driven by a motor, the edge paint rollers can rotate in one direction, avoiding repeated contact between the edge paint rollers and the leather in the same position, which would prevent the edge paint in that position from being effectively replenished after use, thus increasing the scrap rate.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] This utility model discloses an automatic edge-oiling machine head, comprising: a base 1, a movable seat 2, and an edge-oiling box 3. The base is used to mount other components of the machine head; therefore, the base 1 can be an independent structure or part of the automatic edge-oiling machine frame. The movable seat 2 is mounted on the base 1, and the edge-oiling box 3 is mounted on the movable seat 2. The movable seat 2 is selectively connected to the base 1 in either a rotating or sliding manner, and then movably connected to the edge-oiling box 3 in the remaining manner, allowing the edge-oiling box 3 to slide along the base 1 and rotate left and right. The movable seat 2 is respectively connected to a first elastic element 4 and a second elastic element 5. The first elastic element 4 is used to reset the position of the movable seat 2 in the sliding direction; the second elastic element 5 is used to reset the position of the movable seat 2 in the rotation direction. The first and second elastic elements are elastic components, including springs, compression springs, or other elastic devices, or other components with springs or elastic devices. In the accompanying drawings, cylinders are used to represent elastic elements. As shown in this embodiment, the movable seat 2 is slidably connected to the base 1; the movable seat 2 is rotatably connected to the edge-oiling box 3. This connection method allows the edge-oiling box 3 to flexibly adjust its position relative to the fixed base 1 or frame. When the robotic arm grips the leather and moves to the edge-oiling box 3 for oiling, even if there are errors in the oiling path or irregular edges of the leather, the leather can still be oiled evenly. Furthermore, it also avoids excessive collision between the robotic arm and the edge-oiling box 3, which could cause the gripped leather to fall off.

[0029] More specifically, in this embodiment, the movable seat 2 slides back and forth relative to the base 1. Of course, in some embodiments, the movable seat 2 can also slide up and down relative to the base 1. The bottom of the movable seat 2 is provided with a groove 20 opening towards the base; the base 1 is provided with a slide platform 11 that cooperates with the groove 20. The groove 20 and the slide platform 11 slide in contact, allowing the movable seat 2 to move back and forth along the base 1, thereby driving the edge-oiling box 3. Of course, in some embodiments, the slide platform can be located at the bottom of the movable seat, and the groove can be located on the base.

[0030] More specifically, the movable seat 2 is provided with a protruding rotating shaft 21; the bottom of the edge-oiling box 3 is pivotally connected to the rotating shaft 21. The edge-oiling box 3 can rotate around the rotating shaft 21. Of course, in some embodiments, the rotating shaft can also be located at the bottom of the edge-oiling box. During the rotation of the edge-oiling box 3, the part of the edge-oiling box 3 used for oiling will swing left and right. When the robotic arm gets too close to the oiling part of the edge-oiling box 3, the edge-oiling box 3 can adjust its position distance from the robotic arm by swinging left and right and moving back and forth to prevent excessive contact. The first elastic element 4 and the second elastic element 5 are used to reset the edge-oiling box 3 after the position changes. After the oiling is completed, the robotic arm clamps the leather and leaves, and the edge-oiling box 3 rebounds and resets itself by the first elastic element 4 and the second elastic element 5.

[0031] More specifically, as shown in the appendix to the instruction manual, the base 1 is provided with a first mounting seat 12; one end of the first elastic element 4 is mounted on the first mounting seat 12, and the other end is abutting and connected to the movable seat 2; the movable seat 2 is provided with second mounting seats 22 on its left and right sides for mounting second elastic elements 5, and the edge-oil box 3 has elastic element grooves 33 at corresponding positions. One end of the second elastic element 5 is mounted on the second mounting seat 22, and the other end abuts against the elastic element groove 33.

[0032] More specifically, the edge oiling box 3 includes a box body 30 and an oiling roller 31; the front end of the box body 30 is provided with an oil collection groove 301; the oiling roller 31 is rotatably installed in the oil collection groove 301; the oil collection groove 301 is used to collect excess edge oil flowing down from the oiling roller 31. Users can manually apply edge oil to the oiling roller 31 or use an automatic edge oiling method. This embodiment discloses an automatic edge oiling structure, including: the groove wall of the oil collection groove 301 is surrounded by a front low wall surface 3011 and a rear high wall surface 3012; the front side of the oiling roller 31 faces the front low wall surface 3011. As shown in the accompanying drawings, the front low wall surface 3011 is located on the front side of the oil collection groove 301, and is the lowest point of the side wall of the oil collection groove 301. The area above the front wall surface 3011 is the working area for leather oiling. The height setting of the front wall surface 3011 also needs to consider the range of motion of the robotic arm. Furthermore, the housing 30 is provided with an oil inlet channel 302 and an oil outlet channel 303; the openings of the oil inlet channel 302 and the oil outlet channel 303 leading to the oil collection trough 301 are located on the rear high wall surface 3012. As shown in the figure, the opening of the oil inlet channel 302 is higher than the oil outlet channel 303. The side oil inlet pipe 6 is connected to the oil inlet channel 302, injecting side oil into the upward oil roller 31. Excess side oil is discharged from the opening of the oil outlet channel 303 to the oil outlet pipe 7.

[0033] More specifically, to adjust the flow rate of the edge oil, a baffle plate 8 is slidably disposed on the oil receiving trough 301 near the openings of the oil inlet channel 302 and the oil outlet channel 303; the baffle plate 8 can block the openings of the oil inlet channel 302 and the oil outlet channel 303; the baffle plate 8 is connected to a handle 81, which extends outside the housing 30. The user can adjust the blocking range of the baffle plate 8 on the openings of the oil inlet and outlet channels through the handle 81, thereby controlling the flow rate of the edge oil.

[0034] More specifically, to prevent excess oil in the oil collection trough 301 from overflowing and soiling the base 1 or even the frame, the box body 30 has an oil receiving trough 304 formed outside the oil collection trough 301; an oil drain outlet 305 is provided at the front end of the oil receiving trough 304. Overflowing oil can flow from the oil receiving trough 304 into the oil drain outlet 305 and be discharged.

[0035] More specifically, the housing 30 also includes an upper cover 32. One end of the oiling roller 31 is rotatably connected to the upper cover 32, and the other end is rotatably mounted in the oil collection trough 301. The oiling roller 31 can be in a state of free rotation without drive within the oil collection trough 301, or it can be driven by a motor. When the oiling roller 31 is driven by a motor, a driven wheel portion 310 is provided at one end of the oiling roller 31 extending out of the upper cover. The driven wheel portion 310 is connected to a driving wheel 10 via a belt 9. Of course, in some embodiments, the driven wheel portion 310 can also be an independent component connected to the oiling roller 31. The driving wheel 10 is driven by a motor 100. The oiling roller can be changed from free rotation to motor drive, improving the oiling yield.
