Description

Technical Field

[0001] This application relates to the technical field of cardboard box production, and in particular to a cutting device for cardboard box production. Background Technology

[0002] In the cardboard box production process, it is usually necessary to punch holes in the cardboard to form handle holes. Existing cardboard box cutting equipment generally uses a hollow ring cutter to vertically punch the cardboard. When the cutter presses down, it penetrates the cardboard, and then the cutter retracts, with waste material discharged from the inner cavity of the cutter.

[0003] However, if the waste material is tilted or deformed in the inner cavity of the cutter, it may get stuck in the inner cavity of the cutter, resulting in poor waste discharge and affecting the stability of continuous production. Utility Model Content

[0004] To improve the convenience of waste discharge, this application provides a cutting device for carton production.

[0005] This application provides a cutting device for carton production, which adopts the following technical solution:

[0006] A cutting device for carton production includes: a support platform, a mounting frame, a first telescopic power source, a pressing seat, a ring cutter, and a resetting component;

[0007] The mounting bracket is mounted on the support platform, the first telescopic power base end is mounted on the mounting bracket, and the ring cutter is connected to the first telescopic power telescopic end through a connector;

[0008] The pressing seat is slidably sleeved on the ring cutter along the vertical direction. The pressing seat has an enclosing part and a pushing part. The enclosing part and the pushing part together enclose a receiving cavity for receiving the ring cutter.

[0009] When the ring cutter is housed in the housing cavity, the enclosing portion covers the ring cutter, the pushing portion is located in the inner cavity of the ring cutter, and the lowest point of the pushing portion is lower than or flush with the lowest point of the ring cutter.

[0010] The reset member is connected between the pressing seat and the ring cutter, and is used to give the pressing seat a spring force to move in the direction of receiving the ring cutter.

[0011] By adopting the above technical solution, and by setting up a pressure seat and a reset component, the ring cutter can automatically retract into the storage cavity of the pressure seat after cutting. During the reset process, the pushing part forcibly pushes the waste material out of the inner cavity of the ring cutter, effectively avoiding the problem of waste material jamming in traditional cutting devices. At the same time, the enclosing part protects the ring cutter and improves the stability of the device during the cutting process.

[0012] Optionally, the reset component includes a connecting rod and a spring; the connecting rod is connected to the ring cutter; the spring connects the connecting rod and the pressing seat, providing the pressing seat with an elastic force to move closer to the ring cutter.

[0013] By adopting the above technical solution and using a linkage and spring reset structure, the pressure seat always has the elastic force to support the ring cutter downwards, thereby improving the stability of cutting and waste discharge.

[0014] Optionally, the first telescopic force and the reset member are each provided in two sets, and the first telescopic force and the reset member are alternately and evenly distributed along the circumference of the circumferential cutter.

[0015] By adopting the above technical solution, the two sets of first telescopic power and reset components are evenly distributed alternately, so that the ring cutter and the pressure seat are subjected to uniform force, thereby improving the cutting accuracy and the stability of the device operation.

[0016] Optionally, the first telescopic force is detachably connected to the connecting member.

[0017] By adopting the above technical solutions, it is easy to quickly disassemble and replace parts, reducing maintenance difficulty and cost.

[0018] Optionally, the lower surface of the pushing part has a recessed groove, and the periphery of the recessed groove is close to the periphery of the pushing part.

[0019] By adopting the above technical solution, a recessed groove is provided on the lower surface of the pusher, reducing the actual contact area between the pusher and the waste material, and lowering the possibility that the waste material will adhere to the pusher due to adsorption force. The periphery of the recessed groove is close to the edge of the pusher, improving the uniformity of force on the waste material during discharge, and further improving the smoothness and reliability of waste material discharge.

[0020] Optionally, the support platform has a clearance hole for the circumferential cutting blade.

[0021] By adopting the above technical solution, a clearance hole is set on the support platform to provide sufficient punching space for the ring cutter, so that the ring cutter can completely penetrate the cardboard during the cutting process, avoiding incomplete cutting or blade damage caused by insufficient space.

[0022] Optionally, the support platform is provided with a support member at the clearance hole that is opposite to the pushing part, for supporting the workpiece to be cut opposite to the pushing part during the punching of the circumferential cutter.

[0023] By adopting the above technical solution, the support component can support the cardboard during the ring cutter's punching, making the cardboard less prone to excessive bending or deformation during the cutting process, thus improving the cutting quality and extending the service life of the cutter.

[0024] Optionally, the support member includes a fixed bracket, a support plate, and a second telescopic force;

[0025] The fixed bracket is fixed relative to the support platform. The second telescopic power base end is hinged to the fixed bracket. The second telescopic power telescopic end is hinged to one end of the support plate. The end of the support plate away from the second telescopic power telescopic end is hinged to the top of the fixed bracket.

[0026] When the second telescopic force extends or retracts, it can drive the support plate to switch between its corresponding first state and second state; the first state is characterized by the support plate surface being horizontal, and the second state is characterized by the end of the support plate connected to the second telescopic force being lower than the opposite end.

[0027] By adopting the above technical solution, the support member drives the support plate to switch between the first state and the second state through the second telescopic power, which can provide stable support during cutting and quickly guide the waste away from the support plate after cutting.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. Through the cooperation of the pressure seat and the reset part, the waste material can be pushed out of the ring cutter after cutting, reducing the problem of waste material jamming and improving the convenience of waste material discharge and production efficiency;

[0030] 2. The support components not only support the cardboard to reduce cutting defects, but also automatically guide waste away, improving cutting quality and continuity. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses a cutting device for cardboard box production. (Refer to...) Figure 1 The cutting device for carton production includes a support platform 1, a mounting frame 2, a first telescopic power unit 3, a pressing seat 4, a ring cutter 5, and a reset component 6.

[0040] Reference Figure 1 and Figure 2 The support platform 1, supported by outriggers, is used to place the cardboard to be cut. The mounting frame 2 is gantry-shaped and is mounted on the support platform 1. The first telescopic power 3 is connected to the mounting frame 2. In this embodiment, the first telescopic power 3 is a telescopic cylinder; in other embodiments, the first telescopic power 3 can also be an electric telescopic rod. The base end of the first telescopic power 3 is mounted on the mounting frame, and the extension direction of the telescopic end of the first telescopic power 3 is vertically downward.

[0041] Reference Figure 2 and Figure 3 The first telescopic power 3 is connected to the ring cutter 5 through the connector 7, and the pressing seat 4 is connected to the ring cutter 5 through the reset part 6.

[0042] Reference Figure 3 and Figure 4 The ring cutter 5 is elliptical in shape, and the connecting parts 7 correspond one-to-one with the first telescopic power 3. Each set of connecting parts 7 includes a through rod 71 and a flange 72 coaxially connected. The flange 72 is fixedly connected to the top of the through rod 71 and is locked to the telescopic end of the first telescopic power 3 by bolts. The end of the through rod 71 away from the flange 72 is fixed to the top of the ring cutter 5. Meanwhile, the pressure seat 4 has a sliding hole for vertically sliding the through rod 71.

[0043] The pressing seat 4 is square in shape and includes an enclosing part 8 and a pushing part 9. The enclosing part 8 and the pushing part 9 together enclose and form a receiving cavity 10 for accommodating the ring cutter 5. The receiving cavity 10 penetrates the bottom of the pressing seat 4 but does not penetrate the top of the pressing seat 4. At the same time, the receiving cavity 10 is connected to the sliding hole.

[0044] When the inner top wall of the receiving cavity 10 abuts against the top surface of the ring cutter 5, the ring cutter 5 is completely housed in the pressing seat 4. At this time, the enclosing part 8 surrounds the outer periphery of the ring cutter 5, and the pushing part 9 enters the inner cavity of the ring cutter 5. In this embodiment, the lowest point of the pushing part 9 and the lowest point of the enclosing part 8 are flush with the lowest point of the ring cutter 5. In other embodiments, the lowest point of the pushing part 9 and the lowest point of the enclosing part 8 may be lower than the lowest point of the ring cutter 5.

[0045] Reference Figure 2 and Figure 3 Each set of reset components 6 includes a connecting rod 61 and a spring 62. The connecting rod 61 is a vertically extending round rod, with its bottom end fixed to the top of the ring cutter 5, and its top end sliding upward through the pressure seat 4 and fixed to an expanded-diameter pressure plate 14. The spring 62 is sleeved on the part of the connecting rod 61 that extends through the pressure seat 4, and the two ends of the spring 62 that are far apart from each other are respectively fixedly connected to the pressure plate 14 and the top of the pressure seat 4. When the ring cutter 5 is completely retracted into the pressure seat 4, the spring 62 is in a compressed state, so that the spring 62 always provides the pressure seat 4 with a spring force to downwardly sleeve the ring cutter 5.

[0046] When the cardboard is not being cut, the telescopic end of the first telescopic force 3 is in the retracted state. At this time, the ring cutter 5 is completely retracted into the pressure seat 4, and there is space between the bottom of the ring cutter 5 and the pressure seat 4 and the surface of the support table 1 for the cardboard to be placed. After the cardboard reaches the cutting position, the first telescopic force 3 extends and retracts. During this process, the bottom surfaces of the enclosure part 8 and the pushing part 9 first abut against the upper surface of the cardboard, and then the ring cutter 5 extends downward from the storage cavity 10 to cut the cardboard. Afterward, the first telescopic force 3 retracts and resets. During this process, the ring cutter 5 is first retracted into the storage cavity 10, so that the waste material in the inner cavity of the ring cutter 5 is blocked by the pushing part 9 and gradually leaves the ring cutter 5 downward. After the ring cutter 5 is completely retracted into the pressure seat 4, the cut waste material completely leaves the inner cavity of the ring cutter 5, and then the ring cutter 5 and the pressure seat 4 together leave the cardboard upward.

[0047] It should be noted that the first telescopic force 3 and the reset component 6 each have two sets. The through rods 71 ​​corresponding to the two sets of telescopic forces are respectively fixed at opposite ends of the ring cutter 5. The connecting rods 61 in the two sets of reset components 6 are respectively fixed on opposite sides of the ring cutter 5. The distance between any adjacent through rods 71 ​​and connecting rods 61 is consistent, so as to improve the stability of the movement of the ring cutter 5 and the pressing seat 4.

[0048] Reference Figure 3 and Figure 4 Furthermore, the lower surface of the pushing part 9 is provided with an upwardly recessed groove 11. The vertical straight-line distance between the inner wall of the pushing part 9 and its own outer peripheral wall is consistent at any point in the groove 11. The inner peripheral wall of the pushing part 9 at the groove 11 is close to its own outer peripheral wall, so that the area of ​​the pushing part 9 pressing against the cardboard is reduced, and thus waste is not easily adsorbed onto the pushing part 9.

[0049] Reference Figure 4 and Figure 5 Furthermore, the support platform 1 has a clearance hole 12 opposite to the pusher 9 and the ring cutter 5. When the ring cutter 5 punches, it extends into the clearance hole 12 to penetrate the cardboard. The support platform 1 has a support member 13 installed at the clearance hole 12 opposite to the pusher 9 to support the cardboard when the ring cutter 5 punches. After the cardboard is punched, the support member 13 can swing to guide the waste material downward away from the support member 13.

[0050] Reference Figure 5 and Figure 6 Specifically, the support member 13 includes a fixed bracket 131, a support plate 132, and a second telescopic force 133. The fixed bracket 131 is fixed to the support platform 1 and includes a support rod 15 extending vertically to the area directly below the clearance hole 12. One bottom end of the support plate 132 is hinged to the top end of the support rod 15 via a pin. In this embodiment, the second telescopic force 133 is a cylinder; in other embodiments, the second telescopic force 133 can also be an electric telescopic rod. The base end of the second telescopic force 133 is hinged to the support rod 15 via a pin, and the hinge point is lower than the hinge point between the support plate 132 and the support rod 15; the telescopic end of the second telescopic force 133 is hinged to the bottom of the support plate 132 away from the support rod 15 via a pin. The hinge axes of the support plate 132 and the support rod 15, the hinge axis of the support plate 132 and the second telescopic force 133, and the hinge axis of the support rod 15 and the second telescopic force 133 are all parallel to each other.

[0051] The second telescopic power 133 drives the support plate 132 to swing by extending and retracting its telescopic end. Specifically, when the telescopic end of the second telescopic power 133 extends, it moves the support plate 132 to the first state. At this state, the support plate 132 is vertically opposite to the inner cavity of the ring cutter 5, and the surface of the support plate 132 extends horizontally. In this state, the support plate 132 supports the part of the ring cutter 5 that is being cut, thereby reducing the bending of the cardboard during punching and reducing burrs and delamination at the cut. When the telescopic end of the second telescopic power 133 retracts, it drives the end of the support plate 132 that is hinged to the second telescopic power 133 to swing downward, so that the waste material leaves the support plate 132 downward from the clearance hole 12.

[0052] It should be noted that the second telescopic power 133 is linked with the first telescopic power 3. When the telescopic end of the first telescopic power 3 extends, the telescopic end of the second telescopic power 133 remains extended. When the telescopic end of the first telescopic power 3 retracts and the pressure seat 4 leaves the cardboard, the telescopic end of the second telescopic power 133 retracts. After a period of time, the telescopic end of the second telescopic power 133 returns to the extended state.

[0053] In addition, in other embodiments, a conveying mechanism consisting of a conveyor belt or rollers can be provided on the support platform 1 to convey the paperboard and move it to the cutting position. Since the conveying mechanism is a common prior art, it will not be described in detail here.

[0054] The implementation principle of the cutting device for carton production in this application embodiment is as follows: the first telescopic force 3 drives the ring cutter 5 and the pressure seat 4 to cut the cardboard. During cutting, the pressure seat 4 first presses the cardboard, and then the ring cutter 5 extends to complete the cutting; during recycling, the ring cutter 5 first retracts into the pressure seat 4, and the pushing part 9 pushes out the waste material to avoid jamming. The support member 13 supports the cardboard during cutting to reduce bending, and swings away the waste material after cutting.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
