Description

Technical Field

[0001] The utility model relates to the field of jewelry equipment, in particular to a tunnel furnace material receiver. Background Art

[0002] During the jewelry production process, the metal strip needs to be annealed in a tunnel furnace and then processed. The ductility of the metal strip after annealing is enhanced. The processed strip is collected by a receiver, which is equipped with a rotating shaft, and the strip is wound around the shaft through the rotation of the shaft. When the strip is pulled as the shaft rotates, the strip is easily deformed due to the tension during rotation, resulting in the strip width becoming narrower, and the thickness and strength of the strip changing, affecting subsequent processing. In actual production, the faster the shaft rotates, the greater the tension on the strip, the greater the deformation of the strip, and the quality of the strip is affected; when the shaft rotates too slowly, it will affect the strip collection efficiency, resulting in reduced efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a tunnel furnace material receiver which can adjust the rotation speed by the pulling force on the material belt to avoid deformation of the material belt.

[0004] In order to solve the above technical problems, the utility model includes a frame, and its structural features are: a material tray that can rotate to collect materials is installed on the frame, and the material tray includes a material tray shaft that is driven to rotate by a driving device, and a fixed roller is installed on the frame, and the fixed roller is located on the lower side of the material tray and close to the incoming material side, and a swingable rocker arm is provided on the lower side of the fixed roller, and a pressing roller is installed on the side of the rocker arm close to the incoming material, and a detection device that can detect the swing position of the rocker arm and thereby adjust the rotation speed of the driving device is installed on the frame.

[0005] After adopting the above structure, the fixed roller and the pressure roller are both located on the side close to the material belt feeding. After the material belt passes through the lower side of the pressure roller, it extends from between the pressure roller and the fixed roller, passes through the upper side of the fixed roller and is wrapped around the material tray shaft. Through the rotation of the material tray shaft, the material belt is driven to be wrapped around the material tray shaft to collect the material. The fixed roller plays the role of supporting the material belt. The fixed roller rotates itself when the material belt is rotated, reducing the friction between the material belt and the fixed roller, and at the same time, the material belt is adjusted from the fixed roller to the angle between the material belt and the material tray shaft. The pressure roller carries gravity, and the pressure roller has the force to press one end of the pendulum downward. The material belt is located below the pressure roller and is pulled upward, so the material belt exerts an upward supporting force on the pressure roller. When the material tray shaft rotates quickly, the material belt is subjected to a large pulling force. At this time, the pulling force generated by the material belt can simultaneously support the pressure roller upward. When the pulling force is upward When the component force on the other side is greater than the gravity of the pressure roller, the pressure roller is driven to move upward, and the swing arm is driven to swing upward at the same time. When it swings to a certain height, it means that the tension on the material strip is too large. At this time, the material strip will be pulled and deformed. When the detection device detects that the swing arm has swung to this point, the speed of the drive device is controlled to reduce the rotation of the material tray shaft, thereby reducing the tension on the material strip and ensuring the quality of the material strip; when the speed of the material tray shaft is reduced, the tension is reduced. When the tension is too small, the material strip cannot support the pressure roller, and the downward pressure of the pressure roller drives the swing arm to swing downward. When it swings to a certain position, it means that the tension is too low and the material collection efficiency is low. At this time, after the detection device detects the swing arm, it adjusts the speed of the drive device to speed up the rotation speed of the material tray shaft. Under the condition that the material strip is not deformed, the material collection speed is guaranteed.

[0006] The fixed roller and the pressing roller are both arranged parallel to the axis of the material tray shaft. The fixed roller is located between the pressing roller and the material tray shaft in the left-right direction and the height direction. As the tension of the material strip increases, the angle of the envelope angle of the material strip on the fixed roller is changed. The fixed roller is located between the pressing roller and the material tray shaft, ensuring that the envelope angle is an obtuse angle when the swing arm swings up and down, avoiding increasing the pressure on the material strip, avoiding the pressing roller from stretching the material strip, causing deformation of the material strip, and ensuring the quality of the material strip.

[0007] A rocker arm fixed shaft is provided at the front end of the rocker arm, and the rocker arm fixed shaft is rotatably connected to the frame. A counterweight block is provided at the end of the rocker arm away from the pressure roller. The counterweight block and the pressure roller are respectively located on both sides of the rocker arm fixed shaft. The distance between the counterweight block and the rocker arm fixed shaft can be adjusted. The gravity of the balancing rocker arm can be adjusted through the counterweight block, and then the pulling force required for the counterweight block to swing up and down can be adjusted according to different material strips, thereby improving the applicability of the equipment.

[0008] An adjusting rod is installed at the end of the rocker arm away from the pressure roller, and the counterweight block is mounted on the adjusting rod. A threaded through hole is provided on the counterweight block, and a knob for rotatingly clamping / releasing the adjusting rod in the threaded through hole is installed on the counterweight block. After the knob is loosened, the counterweight block moves on the adjusting rod, and the distance between the counterweight block and the swing center point of the rocker arm is adjusted, and the force when one end of the pressure roller moves downward is adjusted, thereby adjusting the tension of the material strip required when the rocker arm swings, thereby adapting to the swing of the rocker when different tensions of different material strips, and then adjusting the rotation speed of the material tray to improve the applicability of the equipment.

[0009] The detection device includes an upper stop switch located on the upper side of the swing arm and a lower stop switch located on the lower side of the swing arm, the upper stop switch includes an upper sensor connecting plate and an upper proximity switch installed on the upper sensor connecting plate, and the lower stop switch includes a lower sensor connecting plate and a lower proximity switch installed on the lower sensor connecting plate. The position of the swing arm is detected by the upper proximity switch. When the swing arm is detected, the speed of the drive device is reduced to reduce the tension on the material belt during material collection. When the swing arm moves downward and the lower proximity switch detects the swing arm, the speed of the drive device is increased to improve the material collection efficiency.

[0010] The upper sensor connecting plate is an L-shaped plate, and the upper sensor connecting plate is connected to the frame through an upper connecting shaft. The upper sensor connecting plate can rotate along the upper connecting shaft. The frame is provided with an upper avoidance hole for avoiding the upper proximity switch. The upper sensor connecting plate is rotated along the upper connecting shaft to adjust the position of the upper proximity switch, thereby adjusting the upward swing range of the swing arm, thereby more accurately regulating the tension of the material belt.

[0011] The lower sensor connecting plate is connected to the frame via a lower connecting shaft. The lower sensor connecting plate can rotate along the lower connecting shaft. The frame is provided with a lower avoidance hole for avoiding the lower proximity switch. The lower sensor connecting plate is rotated along the lower connecting shaft to adjust the position of the lower proximity switch, thereby adjusting the downward swinging range of the pendulum and performing more precise regulation of the tension of the material belt.

[0012] Two material blocking disks are installed on the material tray shaft, and the distance between the two material blocking disks is consistent with the width of the material belt. The positions of the two material blocking disks on the material tray shaft can be adjusted. The two material blocking disks prevent the material belt from skewing when the material belt is wound, thereby ensuring the stability of material collection. By adjusting the position of the material blocking disks, it can adapt to material belts of different widths, thereby improving the applicability of the equipment.

[0013] A mounting block is provided on the outer side of the material retaining plate, and the mounting block can clamp the material retaining plate shaft. By clamping the material retaining plate shaft through the mounting block, the movement of the material retaining plate is avoided, thereby ensuring the quality of material collection.

[0014] A moving wheel is installed at the lower end of the frame to facilitate the movement of the material receiver.

[0015] In summary, the utility model has the advantages of preventing the material strip from being deformed by tension, ensuring the material strip receiving quality, ensuring the material receiving efficiency, and improving applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1-5 As shown, the utility model relates to a tunnel furnace material receiver, which includes a frame 1, a rotatable material tray 2 is mounted on the frame 1, and an adjustment device is provided below the material tray 2 to adjust the rotation speed of the material tray 2 according to the tension of the material belt. Figure 1 The left side is left, the right side is right, set Figure 1 The vertical paper surface facing inward is the front, and the vertical paper surface facing outward is the back. In the field of jewelry processing, after the metal strip is annealed in a tunnel furnace, the metal strip has good ductility and is easily deformed by tension, resulting in changes in the thickness and width of the strip, which has an adverse effect on subsequent processing and production. The material tray 2 on the frame 1 can rotate, driving the strip to be wound on the material tray 2. When the winding speed is fast, the tension on the strip is large, and when the winding speed is slow, the tension on the strip is small. In actual use, it is necessary to control the rotation speed of the material tray 2 within a certain range. The rotation speed of the material tray 2 should not be too slow, which affects the material collection efficiency, and the rotation speed should not be too fast, which causes the material strip to be deformed after being subjected to tension. Therefore, an adjustment device is used. The adjustment device can adjust the rotation speed of the material tray 2 according to the tension on the strip, so as to ensure that the strip will not be deformed by force during the material collection process, thereby ensuring the production quality. A moving wheel 7 is installed at the lower end of the frame 1 to facilitate the movement of the material collector.

[0022] like Figure 1-5As shown, the material tray 2 includes a material tray shaft 21 mounted on the frame 1, and a motor for driving the material tray 2 to rotate is installed behind the material tray shaft 21. The material tray shaft 21 is rotatably connected to the frame 1 through a bearing. Two material blocking discs 22 are installed on the material tray shaft 21. The two material blocking discs 22 are of the same size and the distance between the two material blocking discs 22 is consistent with the width of the material belt. The position of the material blocking disc 22 on the material tray shaft 21 can be adjusted, and the distance between the material blocking discs 22 is adjusted according to different material belt widths, thereby ensuring that the position of the material belt wrapped on the material tray 2 is stable when the material tray 2 rotates. The material blocking disc 22 is a circular piece, and the material blocking disc 22 is mounted on the material tray shaft 21, and the center of the circle of the material blocking disc 22 is consistent with the axis center of the material tray shaft 21. The front side of the front material stopper 22 and the rear end of the rear material stopper 22 are both provided with clamping blocks, which are mounted on the material stopper shaft 21. The clamping blocks are provided with radial bolt holes, and the material stopper shaft 21 is clamped by bolts (bolts not shown in the figure), thereby fixing the position of the material stopper 22. When the position of the material stopper 22 needs to be adjusted, the bolts are loosened, and then the positions of the material stopper 22 and the clamping blocks are adjusted, and then the bolts are clamped again. The clamping blocks are respectively located at the front side of the front material stopper 22 and the rear side of the rear material stopper 22, so as to avoid affecting the material belt during material collection while adjusting and fixing the position of the material stopper 22. When the material tray shaft 21 rotates, the material strip is wound around the material tray shaft 21 in circles, and the blocking plate 22 blocks the material strip from the front and back sides to prevent the material strip from deviating. As the diameter of the wound material strip gradually increases, when it is wound close to the diameter of the blocking plate 22 or the material strip is completely wound, the rotation of the material tray shaft 21 is stopped, and then the clamping block of the rear blocking plate 22 is loosened, and the rear blocking plate 22 is removed along the material tray shaft 21, and then the material sheet that is wound around the material tray shaft 21 is removed, completing the material sheet winding process.

[0023] like Figure 1-5As shown, the adjustment device is located at the lower side of the material tray 2, and the adjustment device includes a fixed roller 3 and a swingable swing rod 4. A pressure roller 41 is installed at one end of the swing rod 4, and the fixed roller 3 can rotate along the axis. A detection device that can detect the position of the swing rod 4 and adjust the speed of the driving device is installed on the frame 1. The material sheet bypasses the pressure roller 41 and the fixed roller 3 and is wound on the material tray shaft 21. The swing rod 4 is rotatably connected to the frame 1 through the swing rod fixed shaft 43, so the swing rod 4 can rotate along the swing rod fixed shaft 43 as the axis. The detection device includes an upper stop switch 5 located on the upper side of the swing rod 4 and a lower stop switch 6 located on the lower side of the swing rod 4. The fixed roller 3 and the pressure roller 41 are both located on the side close to the discharge port of the tunnel furnace. When the material strip comes out of the tunnel furnace, it first passes through the adjustment device and then is wound on the material tray shaft 21. The fixed roller 3 is located between the pressure roller 41 and the pressure plate shaft in both the left and right directions and the up and down directions. In this embodiment, the fixed roller 3 and the pressing roller 41 are both located at the lower left of the tray shaft 21. In other embodiments, the fixed roller 3 and the pressing roller 41 can be located at the lower right of the tray shaft 21. The material belt passes through the lower side of the pressing roller 41, enters between the pressing roller 41 and the fixed roller 3, and is wound around the tray shaft 21 by fitting above the fixed roller 3. Because the pressing roller 41 is located at one end of the swing rod 4, the gravity exerted on the pressing roller 41 presses the end of the swing rod 4 on which the pressing roller 41 is installed to move downward, and the swing rod 4 swings along the swing rod fixed shaft 43. After the material belt is processed in the tunnel furnace, it first passes through the lower side of the material roller, fits with the pressing roller 41, passes between the pressing roller 41 and the fixed roller 3, and is wound around the tray shaft 21 by fitting above the fixed roller 3. During the material collection process, the material belt is fixed in the moving position between the fixed roller 3 and the tray shaft 21. When the material strip is being wound, the envelope angle of the material strip on the fixed roller 3 changes with the rotation speed of the material tray shaft 21. When the rotation speed is faster, the material strip is subjected to tension, the pressure roller 41 is lifted by the material strip, and the envelope angle increases. When the rotation speed is slower, the upward force of the material strip is less than the pressure of the pressure roller 41, and the material strip is pressed downward by the pressure roller 41, and the envelope angle on the fixed roller 3 is smaller. By observing the position of the pressure roller 41, the tension of the material strip can be further determined. An upper stop switch 5 is provided above the pendulum. When the rotation speed is too fast, the pressure roller 41 is driven upward, and when the swing rod 4 swings to the upper stop switch 5, the sensor on the upper stop switch 5 detects the swing rod 4, sends a signal, reduces the speed of the drive motor, and then reduces the material winding speed to prevent the material strip from being deformed due to excessive tension. A lower stop switch 6 is provided below the swing member. When the rotation speed is too slow, the pressing roller 41 presses the material strip downward, driving the swing rod 4 to swing downward. When the swing rod 4 swings to the lower stop switch 6, the sensor on the lower stop switch 6 detects the swing rod 4 and sends a signal to speed up the driving motor speed, thereby increasing the material collection speed and ensuring the material collection efficiency without affecting the shape and quality of the material strip. The signal transmission process of the sensors of the upper stop switch 5 and the lower stop switch 6 is a prior art and will not be described in detail here.

[0024] like Figure 1-5As shown, a counterweight 42 is installed at one end of the swing rod 4 away from the press roller 41, and the counterweight 42 can adjust the distance between the counterweight 42 and the swing rod fixed shaft 43. The counterweight 42 is adjusted to adjust the position between the counterweight 42 and the swing rod fixed shaft 43, and the gravity of one end of the counterweight 42 is balanced, thereby adjusting the swing force of the swing rod 4. In this embodiment, an adjustment rod is installed at one end of the swing rod 4 away from the press roller 41, and the counterweight 42 is sleeved on the adjustment rod. The counterweight 42 is provided with a threaded through hole, and the counterweight 42 is installed on the threaded through hole. The knob for rotating the clamping / releasing the adjustment rod is installed on the counterweight 42. After the knob is released, the counterweight 42 moves on the adjustment rod. By adjusting the distance between the counterweight 42 and the swing center point of the swing rod 4, the force when one end of the press roller 41 moves downward is adjusted, thereby adjusting the tension of the material strip required when the swing rod 4 swings, thereby adapting to the swing of the pendulum when different tensions of different material strips, thereby adjusting the rotation speed of the material tray 2, and improving the applicability of the equipment. The farther the distance between the counterweight block 42 and the swing rod fixed axis 43 is, the smaller the swing force on the swing rod 4 is. The gravity of the counterweight block 42 can be adjusted according to the tension that different types of tapes can withstand, so that the gravity of the press tape matches the tension of the tape, increasing the applicability of the equipment.

[0025] like Figure 1-5 As shown, the upper stop switch 5 includes an upper sensor connecting plate 51 and an upper proximity switch 52 installed on the upper sensor connecting plate 51, and the lower stop switch 6 includes a lower sensor connecting plate 61 and a lower proximity switch 62 installed on the lower sensor connecting plate 61. The upper sensor connecting plate 51 is an L-shaped plate, and an upper connecting shaft is provided at the front end of the upper sensor connecting plate 51. The upper sensor connecting plate 51 is connected to the frame 1 through the upper connecting shaft, and the upper sensor connecting plate 51 can rotate along the upper connecting shaft. The frame 1 is provided with an upper avoidance hole for avoiding the upper proximity switch 52. The upper sensor connecting plate 51 is rotated along the upper connecting shaft to adjust the position of the upper proximity switch 52, thereby adjusting the upward swing range of the swing arm 4, and then more accurately regulating the tension of the material belt. The lower sensor connecting plate 61 is rotatably connected to the frame 1 through the lower connecting shaft. The lower sensor connecting plate 61 can rotate along the lower connecting shaft. The frame 1 is provided with a lower avoidance hole for avoiding the lower proximity switch 62. The lower sensor connecting plate 61 is rotated along the lower connecting shaft to adjust the position of the lower proximity switch 62, and then the downward swinging range of the pendulum is adjusted to more accurately regulate the tension of the material belt.
