Since the material is granular, the tension of the tension spring can be adjusted to ensure that the material will not be crushed. At the same time, sufficient friction must be provided to the material. The active roller and the driven roller can be made into a rubber-coated form. The two gear levers are installed at the bottom of the mounting plate and are located on the side where the material enters the gap between the active roller and the driven roller.

[0070] Frame assembly 1

[0071] like Figure 1-4 As shown, the base 101 is rectangular in design, and universal wheels 107 are provided at the four sides of the bottom of the base 101. A support 102 is provided at the middle position of one end of the upper surface of the base 101. The interior of the support 102 is hollow and can accommodate wires or cables. A triangular support piece is provided on one side of the bottom end of the support 102 to enhance the installation stability of the support 102. One side of the support 102 is flush with the side of the base 101, and the other side opposite to the support 102 is provided with a second hanging scroll 106 from bottom to top. Roller 105, first hanging reel 104, first passing roller 103, and the first hanging reel 104 and the second hanging reel 106 are located on the same vertical line, the first passing roller 103 and the second passing roller 105 are fixed on the pillar 102 in an L-shape, the lower end of the L-shape is fixed on the pillar 102, and the upper end of the L-shape is parallel to the central axis direction of the first hanging reel 104 (and the second hanging reel 106), wherein the upper end of the L-shape is a round stick, which is used as a passing roller, and the lower end of the L-shape is a long strip of fixed plate, which can be fixed on the pillar 102.

[0072] Two retaining rings are provided on the first passing roller 103, namely the first retaining ring 1031 and the second retaining ring 1032. The distance reserved between the first retaining ring 1031 and the second retaining ring 1032 is greater than or equal to the width of a material roll, and the first retaining ring 1031 and the second retaining ring 1032 are symmetrically arranged in the middle position of the first passing roller 103 so that the material passes through the center position of the first passing roller 103 when being put in.

[0073] One end of the first hanging reel 104 is fixed on the pillar 102, and the other end of the first hanging reel 104 is provided with a first limit ring 1041, which is used to limit the position of the material roll on the first hanging reel 104 together with the pillar 102 to prevent the material roll from falling off the first hanging reel 104 when being put into use; similarly, one end of the second hanging reel 106 is fixed on the pillar 102, and the other end of the second hanging reel 106 is provided with a second limit ring 1061.

[0074] When the material roll on the first hanging reel 104 is in use, the material roll on the second hanging reel 106 is on standby, which shortens the replacement time as much as possible and avoids downtime and waiting, which affects production efficiency.

[0075] The width of the material roll is much larger than the width of the material. The second roller 105 has a guiding function and is used to separate the material from the material roll. After the first roller 103 and the first retaining ring 1031 and the second retaining ring 1032 sleeved on the first roller 103, the material is arranged to the center position of the first roller 103, that is, between the two retaining rings. Figure 3 shown.

[0076] In addition, the outer diameter of the rolled material is generally less than 360mm, the width is less than 280mm, and the weight is within 10kg. The hanging reel is mostly fixed, and there is a limit ring on the outside to prevent the material roll from falling when the material is pulled and rotated.

[0077] Drive component 2

[0078] like Figure 5-7 As shown, the driving assembly 2 is installed at the top of the pillar 102 , and the central axis of the driving assembly 2 is oriented in the same direction as the central axes of the first reel 104 and the second reel 106 .

[0079] like Figure 4 As shown, a mounting plate 201 is provided at the top of the pillar 102. The mounting plate 201 is rectangular in design, and its length is aligned with the central axis of the first and second reel-hanging shafts 104 and 106. That is, a portion of the mounting plate 201 is mounted on the top surface of the pillar 102, and the other portion of the mounting plate 201 extends horizontally toward the side of the pillar 102 where the roller and reel are provided. Figure 6 As shown, a motor 202 is provided at a position on the mounting plate 201 located on the top surface of the pillar 102, and the bottom end of the motor 202 is fixed to the mounting plate 201 through a motor bracket, and two spaced side plates are provided at a position on the mounting plate 201 directly above the first hanging reel 104, and the motor 202 shaft is connected to the driving shaft 2041 through a coupling 203, and the central axes of the motor 202 shaft and the driving shaft 2041 are oriented in the same direction as the central axes of the first hanging reel 104 and the second hanging reel 106, and the driving shaft 2041 is located directly above the first hanging reel 104, and the two ends of the driving shaft 2041 pass through the two side plates respectively, and an active roller 204 is fixedly configured on the outer side of the circumference of the middle body of the driving shaft 2041, and bearings are provided at corresponding positions of the two side plates, and the two side ends of the driving shaft 2041 are mounted in the bearings of the two side plates, and the bearings can be designed as flanged bearings.

[0080] The side plate close to one end of the motor 202 shaft is set as the first side plate 206, and the side plate away from the motor 202 shaft is set as the second side plate 207. A first limiting groove 2061 is provided at the middle position of the upper end of the first side plate 206, and a second limiting groove 2071 with the same depth as the first limiting groove 2061 is provided at the middle position of the upper end of the second side plate 207, so as to place the driven shaft 2051, so that the driven shaft 2051 can only move up and down along the limiting groove. A driven roller 205 is fixedly configured on the outside of the driven shaft 2051. The driven roller 205 is located directly above the active roller 204, and the material passes through the gap between the driven roller 205 and the active roller 204. On the first side plate 206 and the second side plate 207, the center of the limit groove and the center of the flange bearing are located on the same vertical line, and the limit groove is located above the flange bearing. A tension spring fixing piece is provided between the bottom end of the limit groove and the flange bearing. One end of the tension spring 213 is fixed on the tension spring fixing piece, and the other end of the tension spring 213 is fixed to one end of the driven shaft 2051. The driven roller 205 relies on its own gravity and the tension of the tension springs 213 at both ends to press the material onto the active roller 204. The motor 202 drives the active roller 204 to rotate, thereby realizing material supply.

[0081] The first side plate 206, facing the motor 202 and coupling 203, forms a closed connection with the first outer cover 208. The second side plate 207, facing away from the driving roller 204 and driven roller 205, forms a closed connection with the second outer cover 209. A wiring groove 2011 is provided on the mounting plate 201 at the top of the support 102 to keep wires and cables organized within the support 102.

[0082] In addition, since the material itself may contain granular components, if it is subjected to excessive pressure between the driven roller 205 and the active roller 204 during the conveying process, the material may be crushed or damaged, affecting the function and quality of the material; therefore, the tension of the tension spring 213 at both ends of the driven shaft 2051 can be adjusted to ensure that the material located between the active roller 204 and the driven roller 205 will not be crushed; at the same time, in order to provide sufficient friction to the material, the active roller 204 and the driven roller 205 can be made into a rubber-coated form.

[0083] There are two gear rods, namely the first gear rod 210 and the second gear rod 211. The first gear rod 210 and the second gear rod 211 are respectively located at the two ends of the active roller 204 in parallel, and the central axes of the first gear rod 210 and the second gear rod 211 are perpendicular to the central axis of the active roller 204. They are located on the side where the material is rolled into the active roller 204 and the driven roller 205. The first gear rod 210 and the second gear rod 211 play a guiding role so that the material will not run out of the main body of the active roller 204 during supply. Since the gear rod needs to be installed on the mounting plate 201, there are also two gear rod brackets, namely the first gear rod bracket 2101 (due to the blocking effect of the position in the figure, Figure 6-7(not shown) and a second gear rod bracket 2111. The first gear rod 210 is fixed to one end of the first gear rod bracket 2101, and the other end of the first gear rod bracket 2101 is mounted on the bottom side of the mounting plate 201 provided with the first side plate 206. The second gear rod 211 is fixed to one end of the second gear rod bracket 2111, and the other end of the second gear rod bracket 2111 is mounted on the bottom side of the mounting plate 201 provided with the second side plate 207. Below one side of the material unwinding active roller 204 and the driven roller 205, the two ends of the baffle 212 are respectively connected to the lower ends of the first side plate 206 and the second side plate 207. The baffle 212 spans the active roller 204 on the mounting plate 201 to prevent the material from being drawn into the gap when rolling out with the active roller 204.

[0084] Detection control component 3

[0085] like Figure 8 As shown, a detection mounting frame 301 and a power switch 307 are embedded in the support 102 located above the first roller 103. The detection mounting frame 301 is an inverted U-shaped structure. A through hole is provided at the corresponding position of the detection mounting frame 301 and the support 102 for the detection rod 302 to pass through. The detection rod 302 is located below the baffle 212, and a part of the detection rod 302 is designed as a straight rod, and the other part of the detection rod 302 is designed as a concave shape. A third retaining ring 306 is provided on the outside of the hole, and a flanged bearing is installed at the through hole of the detection mounting frame 301. One end of the straight rod part of the detection rod 302 passes through the third retaining ring 306 and the flanged bearing, and is connected to the detection plate 303. A micro switch 305 is provided below the detection plate 303, and the micro switch 305 can be fixed on one side of the detection mounting frame 301; a detection limit rod 304 is provided obliquely below the concave part of the detection rod 302, and the detection limit rod 304 is fixed to the L-shaped bottom end of the first roller 103.

[0086] At one side of the support column 102 where the detection and control assembly 3 is installed, an outer cover structure is provided, which can be opened so that the staff can visually detect or repair internal faults.

[0087] How it works

[0088] The roll material feeding device is used in conjunction with the material delivery device. In the initial waiting state, the detection rod 302 rests on the detection limit rod 304. The material in the material roll on the first hanging reel 104 is manually forced to pass through the gap between the active roller 204 and the driven roller 205, and then passes through the bottom of the detection rod 302 and is placed on the material delivery device. When the material delivery device is started, the material gradually becomes tighter as it is pulled upward, and the detection rod 302 is also lifted upward by the material. When the detection rod 302 is lifted, it drives the detection plate 303 to rotate, and the detection plate 303 triggers the micro switch 305. After the micro switch 305 is triggered, it will immediately send out an electrical signal, which is a closed circuit signal. The electrical signal is transmitted to the control component through the wires inside the support 102. After receiving the electrical signal, the control component starts the motor 202, and the motor 202 runs according to the preset rotation cycle to supply the material. The active roller 204 rotates under the action of the motor 202 to drive the material forward, so that the length of the continuous string of materials between the material on the roll material feeding device and the material on the material feeding device is relaxed, and the material is no longer tightened upward. The detection rod 302 moves downward and stops at the detection limit rod 304 (see Figure 9 ), the detection plate 303 resets, and the micro switch 305 returns to the untriggered state. At this time, the material supply is sufficient within the preset rotation cycle of the motor 202. When the motor 202 completes the preset rotation cycle, the motor 202 stops running, the driving roller 204 stops rotating, and the material stops moving. However, the material feeding device does not stop running and continues to drive the material in front of it forward. At this time, the material clamped by the roll material feeding device remains stationary, and the material is pulled upward, and the feeding process is repeated. When the motor 202 is running, the preset rotation cycle of the motor 202 has not been completed, and the staff has timely adhered the head end of the first material in the material roll on the second hanging reel 106 to the end of the last material in the material roll on the first hanging reel 104. In this case, when the motor 202 has completed its rotation according to the preset rotation cycle, the motor 202 stops running, the active roller 204 no longer rotates, and the material stops moving forward, but the material feeding device does not stop running, and the material feeding device continues to drive the material in front to move forward. At this time, the material clamped on the roll material feeding device remains stationary, the material is pulled upward, and the detection rod 302 is also lifted up by the material. When the detection rod 302 is lifted, it drives the detection plate 303 to rotate, and the detection plate 303 triggers the micro switch 305. After the micro switch 305 is triggered, an electrical signal is sent, and the motor 202 on the roll material feeding device starts to continue supplying material.

[0089] It should be noted that regardless of whether the preset rotation cycle of the motor 202 is completed, when the material roll on the first hanging reel 104 is about to run out, the staff will promptly stick the head end of the first material in the material roll on the second hanging reel 106 to the end of the last material in the material roll on the first hanging reel 104, which can ensure that the material delivery equipment will not stop and ensure the continuous supply of materials.

[0090] When the preset rotation cycle of the motor 202 has been completed and the motor 202 stops running, when the roll material on the first hanging reel 104 is about to run out, the staff fails to promptly stick the head end of the first material on the material roll on the second hanging reel 106 to the end of the last material on the material roll on the first hanging reel 104, the material feeding device will have a detection, and when the material feeding device cannot detect the material, the material feeding device will stop running and give an alarm. After the staff successfully reconnects the materials on the two material rolls, the material feeding device will start and drive the material in front of it forward. In the process of the material being pulled up, the detection rod 302 is also lifted up by the material. When the detection rod 302 is lifted, it drives the detection plate 303 to rotate. The detection plate 303 triggers the micro switch, sends an electrical signal, and starts the motor 202. The motor 202 runs according to the preset rotation cycle and continues to supply material.

[0091] To sum up, the roll material feeding device provided by the present application includes three parts, namely a frame assembly, a driving assembly and a detection and control assembly. The frame assembly is equipped with multiple hanging reels, and a material roll is placed on each hanging reel. When a material roll is in use, the material rolls on other hanging reels are on standby to shorten the replacement time as much as possible, avoid production line downtime and waiting, and affect efficiency. Each hanging reel is equipped with a passing roller above it, which not only plays a guiding role to separate the material from the material roll, but also has two retaining rings on the top passing roller to organize the material to the middle position of the active roller. A limiting retaining ring is provided on the outside of each hanging reel to prevent the material roll from falling when the material is pulled and rotated; a limiting groove is provided on the upper end of the two side plates in the driving assembly, so that the driven roller can only move up and down along it, one end of the tension spring is fixed on the side plate, and the other end of the tension spring is connected to the driven shaft, and the driven roller relies on its two sides to pull The spring tension and its own gravity press the material against the active roller, and the motor drives the active roller to rotate, thereby realizing material feeding. Since the material is granular, the tension of the tension spring can be adjusted to ensure that the material will not be crushed. At the same time, sufficient friction must be provided to the material. The active roller and the driven roller can be made into a rubber-coated form. The two gear levers are installed at the bottom of the mounting plate and are located on the side where the material enters the gap between the active roller and the driven roller. The two gear levers prevent the material from running out of the range of the active roller during feeding. The baffle is located on the side where the material exits the gap between the active roller and the driven roller. The baffle can prevent the material from being rolled into the frame gap with the active roller. The detection control component judges the start or stop status of the roll material feeding device by the pulling condition of the detection rod driven by the tension degree of the material. In addition, by setting the preset rotation cycle of the motor each time, the material supply is set to step supply to ensure stable material supply.
