Description

Technical Field

[0001] The present application relates to the field of blister tray cutting, and in particular to an automatic blister tray cutting device. Background Art

[0002] A blister tray is also called a blister tray or a plastic tray. The plastic hard sheet is made into a plastic with specific grooves by the blister process, and the product is placed in the groove to play a role in protecting and beautifying the product. There is also a transport-type tray packaging, and most of the trays are used for convenience.

[0003] Currently, the blister tray is formed by unwinding and conveying a roll of plastic hard sheet, and then blistering the plastic hard sheet, so that the blister tray is processed and formed. The formed blister tray usually needs to be cut to separate the multiple blister trays from each other, so as to realize the individual packaging treatment of the blister tray.

[0004] However, when cutting the blister tray in the traditional method, the blister tray is usually detected by a sensor to control the conveying and stopping of the blister tray. However, due to the certain delay in the feedback of the detection result of the sensor on the blister tray, the cutting position is likely to deviate. Summary of the Invention

[0005] In order to improve the cutting accuracy of the blister tray, the present application provides an automatic blister tray cutting device.

[0006] The present application provides an automatic blister tray cutting device, adopting the following technical solutions:

[0007] An automatic blister tray cutting device includes a frame. An installation frame and a cutting device for cutting the blister tray are arranged inside the frame. A conveying device and a control device for conveying the blister tray are arranged on the installation frame. The control device includes a positioning control mechanism, a conveying control mechanism, and a cutting control mechanism. The positioning control mechanism and the conveying control mechanism are both connected to the conveying device. The positioning control mechanism is connected to the conveying control mechanism. The conveying control mechanism and the positioning control mechanism are both connected to the cutting control mechanism. The cutting control mechanism controls the cutting device to cut the blister tray conveyed in the conveying device.

[0008] By adopting the above technical solutions, the blister tray is conveyed by the conveying device. During the conveying process, the positioning control mechanism controls the conveying device to convey the blister tray or stop the blister tray from moving through the conveying control mechanism, and drives the cutting control mechanism to work through the conveying control mechanism, so as to realize the action of controlling the cutting device to cut the blister tray. Through the mechanical cooperation among the positioning control mechanism, the conveying control mechanism, and the cutting control mechanism, the delay occurring in the cutting work is reduced, so as to facilitate achieving the effect of improving the cutting accuracy of the blister tray.

[0009] In a specific feasible implementation, the cutting device includes a cutting frame, a driving mechanism, and a cutting knife. The cutting frame is installed inside the machine frame and above the mounting frame. The driving mechanism is installed on the cutting frame, and the cutting knife is installed on the driving mechanism.

[0010] By adopting the above technical solution, the driving mechanism drives the cutting knife to move, thereby cutting the plastic suction trays in the conveying device, facilitating the separation of multiple plastic suction trays from each other.

[0011] In a specific feasible implementation, the driving mechanism includes a driving cylinder, and the cutting knife is installed on the piston rod of the driving cylinder through a mounting plate.

[0012] By adopting the above technical solution, it is convenient to achieve the effect of driving the cutting knife to move through the driving cylinder.

[0013] In a specific feasible implementation, a detection camera for detecting the plastic suction trays on the mounting frame is further installed on the mounting plate.

[0014] By adopting the above technical solution, it is convenient to detect the plastic suction trays in the conveying device through the detection camera, thereby controlling the start and stop of the conveying device according to the conveying situation of the plastic suction trays.

[0015] In a specific feasible implementation, the conveying device includes a first conveying roller, a second conveying roller, and a driving frame. The driving frame is installed on the mounting frame. Both the first conveying roller and the second conveying roller are installed on the driving frame, and there is a gap for the plastic suction trays to pass between the first conveying roller and the second conveying roller. Driving sources for driving the first conveying roller and the second conveying roller to rotate are provided at the ends of the first conveying roller and the second conveying roller, and both the first conveying roller and the second conveying roller are connected to the control device.

[0016] By adopting the above technical solution, it is convenient to drive the first conveying roller and the second conveying roller to rotate through the driving sources, thereby realizing the action of conveying the plastic suction trays, and controlling the distance between the first conveying roller and the second conveying roller through the control device. When the distance between the first conveying roller and the second conveying roller increases, the conveying device stops conveying the plastic suction trays. When the distance between the first conveying roller and the second conveying roller returns to the initial distance, the conveying device continues to convey the plastic suction trays.

[0017] In a specific feasible implementation, the control device includes a positioning control mechanism, a conveying control mechanism, and a cutting control structure. The positioning control mechanism includes a synchronous belt and a control block. The synchronous belt is installed on a mounting frame, and the synchronous belt passes through the gap between the first conveying roller and the second conveying roller. The side walls of the synchronous belt are respectively in contact with the circumferences of the first conveying roller and the second conveying roller. A chute is provided on the side wall of the mounting frame, and a slider is installed in the chute. The slider is connected to the synchronous belt. The control block is installed on the side wall of the slider and is connected to the conveying control mechanism. The control block is also connected to the cutting control mechanism.

[0018] By adopting the above technical solution, it is convenient to drive the synchronous belt to move through the first conveying roller and the second conveying roller, thereby driving the slider on the synchronous belt to move, and then enabling the slider to drive the control block to move, so as to realize the action of controlling the conveying control mechanism and the cutting control mechanism to work through the control block.

[0019] In a specific feasible implementation, the conveying control mechanism includes a control column, a first ejector rod, a second ejector rod, a third ejector rod, and a reset member. The control column is installed in the mounting frame. The control block is used to drive the control column to move, and the control column is connected to the cutting control mechanism. A convex block is installed on the side wall of the control column. The first ejector rod is installed on the inner wall of the mounting frame.

One end of the third ejector rod is connected to the second conveying roller, and the other end is connected to the end of the first ejector rod away from the control column. The reset member is installed on the mounting frame, and both the first ejector rod and the control column are connected to the reset member.

[0020] By adopting the above technical solution, it is convenient to move the control block to be in contact with the control column, so that the control column pushes the first ejector rod to move, and the first ejector rod pushes the second ejector rod and the third ejector rod to move, so as to increase the distance between the first conveying roller and the second conveying roller, and thus stop the movement of the plastic suction tray. At the same time, the cutting device is controlled to work through the control column. After the cutting device completes the work, the control block is driven by the cutting control mechanism to separate from the control column, so that the control column and the first ejector rod are reset under the action of the reset member, and the first conveying roller and the second conveying roller continue to convey the plastic suction tray and the synchronous belt.

[0021] In a specific feasible implementation, the reset member includes a first reset spring and a second reset spring. One end of the first reset spring is connected to the mounting frame, and the other end is connected to the end of the control column away from the control block. A reset plate is installed on the side wall of the first ejector rod. The second reset spring is installed on the second ejector rod, and one end of the second reset spring is connected to the side wall of the reset plate, and the other end is connected to the mounting frame.

[0022] By adopting the above technical solution, when the control block is separated from the control column under the control of the cutting control mechanism, it is convenient to reset the control column through reset spring 1, and reset the push rod 1 through reset spring 2, so that the control column can repeatedly control the conveying of the blister tray and the cutting action of the cutting device under the control of different control blocks.

[0023] In a specific possible implementation scheme, the cutting control mechanism includes a control rod and a control button for controlling the start and stop of the driving cylinder, the control button is installed on the mounting frame, the control column controls the operation of the cutting device through the control button, the control rod is installed on the mounting plate, and the control rod is connected to the control block.

[0024] By adopting the above technical solution, it is convenient to press the control column down through the control block so that the control column touches the control button, so as to control the start and stop of the driving cylinder through the control button, thereby realizing the cutting action. When the cutting action is completed and the cutting knife is reset, the control block is driven to move upward through the control rod, so that the control block is separated from the control column, so that the control column is reset under the action of the reset spring 1, so that the push rod 1 can be reset under the action of the reset spring 2, so that the conveying roller 1 and the conveying roller 2 can convey the blister disc again.

[0025] In a specific feasible implementation scheme, a control plate is rotatably mounted on the side wall of the control block, a torsion spring is mounted on the rotating shaft of the control plate, one end of the torsion spring is in contact with the control block, and the other end is in contact with the control plate, a push plate is mounted on the end of the control rod, and the push plate is used to drive the control plate to move, a control groove is opened on the side wall of the control block, the slider is mounted in the control groove through a guide plate, a control spring is also mounted in the control groove, one end of the control spring is connected to the side wall of the control groove, and the other end is connected to the guide plate.

[0026] By adopting the above technical solution, when the control block presses down the control column, so that the control column controls the cutting device to work through the control button, during cutting, the control rod falls to push the control plate to rotate, and when the control rod continues to move downward over the control plate, the control plate is reset under the action of the torsion spring. When the cutting work is completed, the control rod moves upward to reset, so that the control rod drives the control plate to move upward, thereby driving the control block to move upward, so that the control block presses the control spring and separates the control block from the control column, which is convenient for resetting the control column and the top rod.

A guide plate 5110 is fixedly installed on the side wall of the sliding block 513. A control groove 514 is formed on the side wall of the control block 512. The control block 512 is slidably installed at one end of the guide plate 5110 away from the sliding block 513 through the control groove 514.

[0053] Referring to Figure 7 and Figure 8 , the conveying control mechanism 52 includes a control column 521, a first ejector rod 523, a second ejector rod 525, a third ejector rod 524 and a reset member. A guide block 522 is fixedly installed on the side wall of the control column 521.

The control column 521 is also connected to the cutting control mechanism 53.

[0055] Referring to Figure 8, the synchronous belt 511 moves under the drive of the first conveying roller 41 and the second conveying roller 44, thereby driving the control block 512 to move. When the control block 512 moves to abut against the control column 521, as the control block 512 continues to move, the control block 512 pushes the control column 521 downward, thereby compressing the first reset spring 528, and pushing the first ejector rod 523 to move through the bump 529, causing the first ejector rod 523 to move in the direction of the first conveying roller 41, and compressing the first reset spring 528, thereby pushing the second ejector rod 525 and the third ejector rod 524 to move, so that the second ejector rod 525 drives the first conveying roller 41 to move in the waist-shaped hole 472, and the third ejector rod 524 drives the second conveying roller 44 to move in the waist-shaped hole 472, making the distance between the first conveying roller 41 and the second conveying roller 44 larger, thereby stopping the synchronous belt 511 and the plastic suction tray from moving, facilitating the cutting device 3 to cut the plastic suction tray.

[0056] Refer to Figure 9 and Figure 10 , the cutting control mechanism 53 includes a control rod 531 and a control button 533. The control button 533 is fixedly installed on the bottom plate 24 and is located below the control column 521. On the basis of setting the control button 533, it is convenient to control the start and stop of the driving cylinder 32 through the control button 533. The control rod 531 is fixedly installed at both ends of the mounting plate 33, and one end of the control rod 531 extends in the direction of the control column 521. A push plate 532 is fixedly installed on the bottom wall of the control rod 531.

[0057] Refer to Figure 11 , a rotating groove 516 is formed on the side wall of the control block 512. A control plate 517 is rotatably installed in the rotating groove 516. The top wall of the control plate 517 abuts against the side wall of the rotating groove 516. A torsion spring 518 is installed on the rotating shaft of the control plate 517. One end of the torsion spring 518 is fixedly connected to the side wall of the rotating groove 516, and the other end is fixedly connected to the side wall of the control plate 517.

[0058] Refer to Figure 9 and Figure 10 , when starting to cut, the driving cylinder 32 controls the mounting plate 33 to descend, thereby driving the control rod 531 to descend, so that the push plate 532 on the control rod 531 pushes the control plate 517 to rotate. When the push plate 532 passes over the control plate 517, the control plate 517 resets under the action of the torsion spring 518.

[0059] Refer to Figure 10 and Figure 11, after the cutting work is completed, the control rod 531 resets with the mounting plate 33, causing the top wall of the push plate 532 to abut against the bottom wall of the control plate 517, thereby driving the control plate 517 to move upward, causing the control plate 517 to drive the control block 512 to move upward, thereby compressing the control spring 515, and causing the control block 512 to separate from the control column 521, so that the control column 521 resets under the action of the first return spring 528, and the first ejector rod 523 resets under the action of the second return spring 526, thereby reducing the distance between the first conveyor roller 41 and the second conveyor roller 44, so as to continue conveying the synchronous belt 511 and the plastic suction tray. When the synchronous belt 511 moves, it drives the control block 512 to continue moving. After the control plate 517 separates from the push plate 532, the control block 512 resets under the action of the control spring 515.

[0060] The working principle of the embodiment of the present application is as follows: The plastic suction tray after thermoforming is conveyed to the conveying platform 471, and the plastic suction tray on the conveying platform 471 is conveyed by the first conveyor roller 41 and the second conveyor roller 44. During the conveying, the abutting column 519 on the synchronous belt 511 is aligned with the position on the plastic suction tray that needs to be cut. The synchronous belt 511 is conveyed by the first conveyor roller 41 and the second conveyor roller 44, thereby driving the plastic suction tray and the control block 512 to move synchronously. When the control block 512 moves to abut against the control column 521, and causes the control column 521 to move downward, pushing the first ejector rod 523 to move, and driving the second ejector rod 525 and the third ejector rod 524 to act, so that the first conveyor roller 41 and the second conveyor roller 44 open. At this time, the synchronous belt 511 and the plastic suction tray stop moving. At the same time, the control column 521 abuts against the control button 533, and the control button 533 controls the driving cylinder 32 to start, so that the driving cylinder 32 drives the mounting plate 33 to move downward, so that the cutting knife 34 on the mounting plate 33 cuts the plastic suction tray.

[0061] After the cutting work is completed, the cutting knife 34 moves upward and resets under the drive of the driving cylinder 32. At the same time, the mounting plate 33 drives the control rod 531 to move upward and reset, so that the push plate 532 on the control rod 531 drives the control plate 517 to move upward, so that the control plate 517 drives the control block 512 to move upward, so that the control block 512 separates from the control column 521, so that the control column 521 and the first ejector rod 523 reset, enabling the first conveyor roller 41 and the second conveyor roller 44 to continue conveying the plastic suction tray and the synchronous belt 511, thereby driving the control block 512 to continue moving, so as to facilitate cutting the next cutting part on the plastic suction tray. When the detection camera 35 detects that there is no plastic suction tray at the position of the cutting knife 34 on the conveying platform 471, the cutting device 3 and the conveying device 4 stop working.

[0062] The above is the preferred embodiment of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
