Description

Technical Field

[0001] This utility model relates to the field of membrane processing technology, and in particular to a feeding device and a die-cutting system. Background Technology

[0002] During the die-cutting process, a feeding device is needed to supply the film material.

[0003] In related technologies, the feeding device includes a feeding roller, on which a roll of film is sleeved. The feeding roller can continuously supply film during rotation. When the film on the feeding roller is exhausted, the operator needs to install a new roll of film on the feeding roller.

[0004] However, before the new membrane material is installed on the feeding roller, the tension of the old membrane material will suddenly decrease because the old membrane material has been supplied to the feeding roller. At this time, the membrane material will shrink, which will cause the membrane material to shift and affect the subsequent processing accuracy of the membrane material. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art. The first aspect of this invention provides a feeding device, in which the film material on the feeding roller maintains a certain tension after feeding is completed. The second aspect of this invention also provides a die-cutting system.

[0006] According to the first aspect of the present invention, a feeding device includes a frame, a feeding roller, a sensing roller, and a pressing module. The feeding roller is rotatably mounted on the frame and is used to supply film material. The sensing roller is mounted on the frame and is used to receive the film material output by the feeding roller. A sensor is provided on the sensing roller and is used to detect the tension of the film material. The pressing module is mounted on the frame and includes a first pressing member, a second pressing member, and a driving assembly. The first pressing member has a first plane, and the second pressing member has a second plane. A pressing channel is formed between the first plane and the second plane, allowing the film material output by the sensing roller to pass through. The driving assembly is drivenly connected to the first pressing member and electrically connected to the sensor. The driving assembly can drive the first pressing member away from the second pressing member when the sensor detection result is greater than a preset value, and can drive the first pressing member to cooperate with the second pressing member to press the film material in the pressing channel when the sensor detection result is less than the preset value.

[0007] The feeding device described in this utility model has at least the following beneficial effects: When the feeding device of this application is applied to a die-cutting system, when the film material on the feeding roller is completely supplied, the sensor on the sensing roller detects that the tension of the film material is less than a preset value. At this time, the drive assembly can drive the first pressing member to move closer to the second pressing member according to the sensor's detection result, so that the first pressing member and the second pressing member cooperate to press the film material in the pressing channel to maintain the tension of the film material, and the feeding device stops conveying the film material. Afterwards, the operator can install a new roll of film material on the feeding roller and connect the end of the roll of film material to the end of the previous roll of film material to enhance the tension of the film material. When the sensor detects that the tension of the film material is greater than the preset value, the drive assembly drives the first pressing member to move away from the second pressing member, and the feeding device can convey the film material normally. Furthermore, by the cooperation of the first pressing member and the second pressing member to press the film material in the pressing channel, the film material can still remain taut after the film material on the feeding roller is completely supplied.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] The following is for reference. Figures 1 to 3 The feeding device of the first aspect of this application will be described in detail.

[0025] refer to Figure 1 and Figure 2According to a first aspect embodiment of the present invention, a feeding device includes a frame 100, a feeding roller 200, a sensing roller 300, and a pressing module 400. The feeding roller 200 is rotatably mounted on the frame 100 and is used to supply film material. The sensing roller 300 is mounted on the frame 100 and is used to receive the film material output by the feeding roller 200. A sensor is provided on the sensing roller 300 to detect the tension of the film material. The pressing module 400 is mounted on the frame 100 and includes a first pressing member 410, a second pressing member 420, and a drive assembly 430. The first pressing member 410... The first pressure member 410 has a first plane 412a, and the second pressure member 420 has a second plane 421. A pressing channel 401 is formed between the first plane 412a and the second plane 421, allowing the film material output by the sensing roller 300 to pass through. The driving component 430 is driven to the first pressure member 410 and electrically connected to the sensor. When the sensor detection result is greater than a preset value, the driving component 430 can drive the first pressure member 410 away from the second pressure member 420, and when the sensor detection result is less than the preset value, it can drive the first pressure member 410 to cooperate with the second pressure member 420 to press the film material in the pressing channel 401.

[0026] It should be noted that after the feeding device is applied to the die-cutting system, it needs to supply film material to the die-cutting device. A roll of film material is loaded onto the feeding roller 200 of the feeding device. The rotation of the feeding roller 200 allows the feeding device to continuously supply film material to the die-cutting device. After the film material on the feeding roller 200 has been completely supplied, the operator needs to load new film material onto the feeding roller 200 and connect the beginning of the new film material to the end of the old film material, so that the feeding device can continue to supply film material to the die-cutting device. However, when the film material on the feeding roller 200 has been completely supplied, the tension of the film material itself will decrease sharply, causing the film material to spring back, resulting in an overall displacement of the film material, which in turn affects the processing accuracy of the die-cutting device.

[0027] In the feeding device of this application, when the film material on the feeding roller 200 is finished being fed, the tension of the film material will decrease. When the sensor detects that the tension of the film material is less than a preset value, the drive component 430 can drive the first pressing member 410 to approach the second pressing member 420, so that the first plane 412a cooperates with the second plane 421 to press the film material in the pressing channel 401 to prevent the film material from shrinking back and to prevent the tension of the film material from decreasing further. After the feeding roller 200 is loaded with new film material and the head end of the new film material is connected to the tail end of the old film material, the tension of the old film material increases under the action of the new film material. When the sensor detects that the tension of the film material is greater than the preset value, the drive component 430 can drive the first pressing member 410 away from the second pressing member 420, and the film material can move normally along the pressing channel 401. The feeding device can normally feed the film material to the die-cutting device.

[0028] Understandably, after the film material is fed on the feeding roller 200, the drive assembly 430 can drive the first pressing member 410 to cooperate with the second pressing member 420 to press the film material in the pressing channel 401, so that the film material maintains sufficient tension and can prevent the film material from shifting due to its own rebound, thereby enabling the die-cutting device to accurately complete the die-cutting process of the film material.

[0029] It is understandable that, since the first pressing member 410 has a first plane 412a and the second pressing member 420 has a second plane 421, after the driving assembly 430 drives the first pressing member 410 to approach the second pressing member 420, the first plane 412a can cooperate with the second plane 421 to press the film material in the pressing channel 401. The arrangement of the first plane 412a and the second plane 421 makes the contact area between the first pressing member 410 and the second pressing member 420 and the film material larger, so that the pressing of the film material by the first pressing member 410 and the second pressing member 420 can be more stable and firm.

[0030] In some embodiments of this utility model, reference is made to Figure 2 The drive assembly 430 includes a mounting bracket 431, a driver 432, and a lead screw 433. The lead screw 433 extends vertically and is rotatably mounted on the mounting bracket 431. The lead screw 433 is threadedly connected to a first pressure member 410. The first pressure member 410 is slidably mounted on the mounting bracket 431 in the vertical direction. The driver 432 is electrically connected to a sensor and is driven by the lead screw 433. The driver 432 is used to drive the lead screw 433 to rotate.

[0031] Furthermore, driven by the actuator 432, the lead screw 433 can rotate, thereby causing the lead screw 433 to drive the first pressing member 410 to move vertically relative to the mounting bracket 431, so that the first pressing member 410 moves closer to or further away from the second pressing member 420. When the tension of the membrane material detected by the sensor is low, the actuator 432 drives the first pressing member 410 to move a greater distance toward the second pressing member 420 through the lead screw 433, so that the first pressing member 410 exerts a greater squeezing force on the membrane material, thereby increasing the overall tension of the membrane material more, so that the overall tension of the membrane material is closer to the preset value. When the tension of the membrane material detected by the sensor is high, the actuator 432 drives the first pressing member 410 to move a smaller distance toward the second pressing member 420 through the lead screw 433, so that the squeezing force of the first pressing member 410 on the membrane material is smaller, thereby increasing the overall tension of the membrane material less, so that the overall tension of the membrane material is closer to the preset value.

[0032] It is understandable that by setting the lead screw 433, the driver 432 can drive the first pressure member 410 to slide accurately in the vertical direction through the lead screw 433, thereby accurately adjusting the tension of the membrane material through the first pressure member 410.

[0033] In some embodiments of this utility model, the driver 432 is a motor, which is located on the horizontal side of the first pressure member 410. The drive assembly 430 also includes a transmission belt 434, and the output end of the motor is connected to the lead screw 433 through the transmission belt 434.

[0034] For example, such as Figure 2 As shown, the motor is located on the rear side of the first pressure member 410, and the drive assembly 430 also includes a transmission belt 434. The output end of the motor is connected to the lead screw 433 through the transmission belt 434.

[0035] Understandably, the arrangement of the transmission belt 434 allows the motor to be positioned on the horizontal side of the first pressing member 410, so that the horizontal space of the first pressing member 410 can be fully utilized, reducing the vertical dimensions of the entire drive module.

[0036] In some embodiments of this utility model, the first pressing member 410 includes a connecting plate 411, a pressing plate 412, and a guide post 413. The upper and lower ends of the guide post 413 are connected to the connecting plate 411 and the pressing plate 412, respectively. The guide post 413 is slidably mounted on the mounting bracket 431 in the vertical direction. The pressing plate 412 forms a first plane 412a away from the plate surface of the connecting plate 411. The lead screw 433 is threadedly connected to the connecting plate 411.

[0037] For example, such as Figure 2 As shown, the first pressing member 410 includes a connecting plate 411, a pressing plate 412, and a guide post 413. The upper end of the guide post 413 is connected to the connecting plate 411, and the lower end of the guide post 413 is connected to the pressing plate 412. The lower plate surface of the pressing plate 412 forms a first plane 412a. The guide post 413 is slidably mounted on the mounting bracket 431 in the vertical direction. The lower end of the lead screw 433 is threadedly connected to the connecting plate 411.

[0038] Furthermore, driven by the driver 432, the lead screw 433 can rotate to drive the entire first pressing member 410 to move up and down through the connecting plate 411.

[0039] In a further embodiment of the present invention, the mounting bracket 431 includes a first mounting plate 431a, a second mounting plate 431b, and a connecting column 431c. The upper and lower ends of the connecting column 431c are respectively connected to the first mounting plate 431a and the second mounting plate 431b. A receiving cavity 431d is formed between the first mounting plate 431a and the second mounting plate 431b. The connecting plate 411 and the motor are both disposed in the receiving cavity 431d. The lead screw 433 is rotatably disposed on the first mounting plate 431a. The guide column 413 is slidably disposed on the second mounting plate 431b in the vertical direction. The pressure plate 412 is disposed on the side of the second mounting plate 431b away from the first mounting plate 431a.

[0040] For example, such as Figure 2 As shown, the mounting bracket 431 includes a first mounting plate 431a, a second mounting plate 431b, and a connecting column 431c. The upper end of the connecting column 431c is connected to the first mounting plate 431a, and the lower end of the connecting column 431c is connected to the second mounting plate 431b. A receiving cavity 431d is formed between the first mounting plate 431a and the second mounting plate 431b. The connecting plate 411 and the motor are both located in the receiving cavity 431d. The lead screw 433 is rotatably mounted on the first mounting plate 431a. The guide column 413 is slidably mounted on the second mounting plate 431b in the vertical direction. The pressure plate 412 is located on the lower side of the second mounting plate 431b.

[0041] It is understandable that by setting the first mounting plate 431a and the second mounting plate 431b, a receiving cavity 431d is formed between the first mounting plate 431a and the second mounting plate 431b, and the connecting plate 411 and the motor are both located in the receiving cavity 431d, the mounting frame 431 as a whole can protect the connecting plate 411 and the motor.

[0042] In some embodiments of this utility model, the frame 100 is provided with a horizontally distributed first guide roller 110 and second guide roller 120. The first guide roller 110 and the second guide roller 120 are respectively arranged adjacent to the inlet end and the outlet end of the pressing channel 401. The first guide roller 110 is used to guide the film material into the pressing channel 401, and the second guide roller 120 is used to receive the film material output from the pressing channel 401.

[0043] For example, such as Figure 2 As shown, the frame 100 is provided with a first guide roller 110 and a second guide roller 120 distributed in the left-right direction. The first guide roller 110 is located at the left entrance end of the pressing channel 401, and the second guide roller 120 is located at the right exit end of the pressing channel 401. Both the first guide roller 110 and the second guide roller 120 extend in the front-back direction. The first plane 412a and the second plane 421 are both parallel to the horizontal plane.

[0044] It is understandable that by setting the first guide roller 110 and the second guide roller 120, the film material located in the pressing channel 401 can be kept in a horizontally extended state under the action of the first guide roller 110 and the second guide roller 120. At this time, the part of the film material located in the pressing channel 401 can be parallel to the first plane 412a and the second plane 421 respectively. During the process of the first pressing member 410 approaching the second pressing member 420, the first plane 412a can completely adhere to the surface of the film material and drive the film material to approach the second plane 421 of the second pressing member 420.

[0045] In some embodiments of this utility model, reference is made to Figure 1The feeding device also includes an adjustment module 500, which is mounted on the frame 100 and located on the moving path of the film material. The adjustment module 500 can adjust the position of the film material in the width direction.

[0046] In a further embodiment of the present invention, the adjustment module 500 includes an adjustment frame, a first limiting member 520 and a second limiting member 530. The adjustment frame is mounted on the frame 100. The first limiting member 520 and the second limiting member 530 are distributed along the width direction of the film material, and the first limiting member 520 and the second limiting member 530 are both adjustablely mounted on the adjustment frame along the width direction of the film material. An adjustment area 501 that allows the film material to pass through is formed between the first limiting member 520 and the second limiting member 530.

[0047] For example, such as Figure 3 As shown, the adjustment module 500 includes an adjustment frame, a first limiting member 520 and a second limiting member 530. The adjustment frame is mounted on the frame 100. The first limiting member 520 and the second limiting member 530 are distributed along the front-back direction. The first limiting member 520 is adjustable in position along the front-back direction and the second limiting member 530 is adjustable in position along the front-back direction. An adjustment area 501 is formed between the first limiting member 520 and the second limiting member 530.

[0048] Understandably, by adjusting the positions of the first limiting member 520 and the second limiting member 530 in the front-back direction, the adjustment area 501 can be adapted to membrane materials of different specifications, and the position of the membrane material can be adjusted in the front-back direction.

[0049] For details, please refer to Figure 3 The first limiting member 520 is slidably mounted on the adjusting frame in the front-to-back direction. The first limiting member 520 has a threaded hole, and a threaded adjusting member 521 passes through the threaded hole. By loosening the threaded adjusting member 521, the operator moves it away from the adjusting frame, reducing the friction between the threaded adjusting member 521 and the adjusting frame. At this point, the operator can smoothly drive the first limiting member 520 to slide in the front-to-back direction. By tightening the threaded adjusting member 521, the operator brings it closer to the adjusting frame, increasing the friction between the threaded adjusting member 521 and the adjusting frame. At this point, the first limiting member 520 is securely fixed to the adjusting frame.

[0050] It should be noted that the position adjustment method of the second limiting member 530 on the adjusting frame is the same as that of the first limiting member 520.

[0051] In some embodiments of this utility model, the adjustment module 500 further includes a scale 540, which is disposed on the adjustment frame and extends along the width direction of the membrane material. The scale 540 is provided with a scale 541 distributed along the width direction of the membrane material, which is used to display the position of the membrane material in the adjustment area 501 in its own width direction.

[0052] For example, such as Figure 3 As shown, the scale 540 extends in the front-back direction and has scales 541 distributed in the front-back direction. The scale 541 in the middle of the scale 540 is the smallest, and the scales 541 on the scale 540 gradually increase in the direction towards the front and back ends of the scale 540.

[0053] Understandably, by setting the scale 540, staff can accurately adjust the position of the membrane material in the adjustment area 501 by referring to the scale 541 on the scale 540 and the first limiter 520 and the second limiter 530.

[0054] The die-cutting system provided according to the second aspect of the present invention includes the feeding device provided in the first aspect of the present invention.

[0055] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
