Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box production equipment, specifically a cardboard box creasing and cutting machine. Background Technology

[0002] A creasing and cutting machine is a device that uses a specific carton template to press each piece of cardboard once. The surface of the cardboard is cut by the uneven surface of the template, forming multiple sets of cartons that can be peeled off. Existing flatbed creasing and cutting machines can simultaneously perform feeding and unloading at one station, which can effectively improve the efficiency of cardboard molding compared to traditional reciprocating conveyor belt molding equipment.

[0003] During the use of the flatbed creasing and cutting machine, thanks to the safety braking device, workers can confidently remove the crimped cardboard from the machine with one hand and put the new cardboard into the machine with the other. During the cardboard replacement operation, the machine can continuously open and close the position of the cardboard being processed.

[0004] In actual production, it has been found that the length and time that the cardboard reaches or leaves the predetermined placement position of the equipment directly affects the length of time that the worker's arm is inserted into the equipment. Both of these factors affect the time from molding one cardboard to replacing it with another. In other words, the longer the arm needs to stay in the equipment, the more difficult it is to pull the arm out of the equipment within the same time after molding the new cardboard. Workers are prone to slow movements due to prolonged work, which can cause the equipment to stop or even lead to safety accidents such as pinching injuries.

[0005] While ensuring equipment safety, the applicant proposed a safer and more efficient indentation and cutting machine. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the prior art by proposing a carton creasing and cutting machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a carton creasing and cutting machine, comprising a swing seat whose one end face can reciprocate close to a base, wherein a plurality of fitting grooves are provided on the end face of the swing seat at intervals along the height direction of the swing seat, a blocking strip is slidably disposed in the fitting groove, an elastic element is provided in the swing seat to pull the blocking strip out of the fitting groove, and a driving component is provided in the swing seat to guide the plurality of blocking strips to retract into the fitting grooves from top to bottom in sequence, and when the blocking strips are retracted into the fitting grooves, the outer end face of the blocking strips coincides with the end face of the swing seat, the blocking strips include a support portion that can slide out of the fitting groove, and the upper end face of the plurality of support portions is inclined to one side towards the ground, and the angle between the support portion and the ground is less than 45 degrees.

[0008] The present invention is further configured such that the angle between the upper end surface of the plurality of support parts and the ground gradually decreases from top to bottom.

[0009] The present invention is further configured such that the upper end face of the support is perpendicular to the end face of the swing seat with the fitting groove.

[0010] The present invention is further configured such that: both ends of the blocking strip are fixedly provided with connecting rods, the swing seat is provided with a receiving groove that connects to the fitting groove, and the driving assembly includes two sets of motors with one end fixedly provided in the swing seat, and a pushing member connected to the other end of the motor. The motor is used to drive the pushing member to abut against the connecting rod until the connecting rod slides into the receiving groove.

[0011] The present invention is further configured such that: the pushing member includes several irregularly shaped wheels coaxially connected to the motor; the periphery of the irregularly shaped wheel includes a limiting part and a yielding part that can form a closed ring surface; the outer contour diameter of the limiting part is larger than the outer contour diameter of the yielding part; the irregularly shaped wheel has a rounded corner structure formed between the limiting part and the yielding part for transition; when the limiting part abuts against the connecting rod, it can push the connecting rod to slide into the receiving groove in a direction away from the axis of the irregularly shaped wheel and position it until the yielding part fits against the surface of the connecting rod, and the supporting part slides out of the fitting groove.

[0012] The present invention is further configured such that the central angles of adjacent limiting portions decrease by the same angle from top to bottom.

[0013] The present invention is further configured such that: the elastic element includes a tension spring, one end of the tension spring is fixedly sleeved on the connecting rod, and the other end of the tension spring is fixedly sleeved on the swing seat.

[0014] In summary, this utility model has the following beneficial effects:

[0015] Firstly, compared to existing technologies, the distance workers need to reach into the equipment when placing cardboard is significantly reduced, allowing workers to complete the cardboard placement operation in a safer manner.

[0016] Secondly, compared to existing technologies, after the cardboard is molded, it can be separated from the state of being attached to the end face of the swing seat due to the reset of the blocking strip. This makes it easier for workers to remove the molded cardboard from the equipment, effectively avoiding the situation where the cardboard is not removed due to being squeezed and is then molded by the equipment again. It also shortens the time for workers to remove the cardboard. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] A cardboard box creasing and cutting machine, such as Figures 1 to 3 As shown, the device includes a base and a swing seat 1. One end face of the swing seat 1 can reciprocate close to the template fixed on the base to mold the cardboard placed between the two. Several fitting grooves 11 are provided on the end face of the swing seat 1 at intervals along the height direction of the swing seat 1. A blocking strip 2 is slidably arranged in the fitting groove 11. An elastic element is provided in the swing seat 1 to pull the blocking strip 2 out of the fitting groove 11. A drive component is provided in the swing seat 1 to guide several blocking strips 2 to retract into the fitting groove 11 from top to bottom. When the blocking strip 2 retracts into the fitting groove 11, the outer end face of the blocking strip 2 coincides with the end face of the swing seat 1. That is, when molding the cardboard, the fitting groove 11 opened on the surface of the swing seat 1 can be filled by the blocking strip 2, so as to press the cardboard on one side with a relatively smooth surface. In this specific embodiment, the elastic element includes a tension spring 5. One end of the tension spring 5 is fixedly sleeved on the connecting rod 22, and the other end of the tension spring 5 is fixedly sleeved on the swing seat 1.

[0025] The blocking strip 2 includes a support portion 21 that can slide out of the fitting groove 11, and the upper end surfaces of several support portions 21 are all inclined to one side and to the ground.

[0026] Usage: In the initial state, when the swing seat 1 moves away from the template on the base due to the swing, all four blocking bars 2 of this application can slide out of the fitting groove 11.

[0027] When the equipment is started and the swing seat 1 begins to swing away from the template, the worker places the cardboard from top to bottom along the end face. The cardboard is placed on the uppermost blocking strip 2, that is, the cardboard is supported by the support part 21 of the uppermost blocking strip 2. At this time, the worker can remove his hand from between the swing seat 1 and the base. As the swing seat 1 swings toward the template, the four blocking strips 2 retract into the fitting groove 11 from top to bottom. The cardboard is allowed to fall step by step because of the four blocking strips 2 retracting into the fitting groove 11 in sequence, so that the cardboard can finally fall into the specific cardboard placement position of the equipment. In order to make the cardboard more stable when it falls on each support part 21, the angle between the upper end face of the support part 21 and the ground is less than 45 degrees. Before the end face of the swing seat 1 pushes the cardboard against the template, the four blocking strips 2 are completely retracted into the fitting groove 11.

[0028] After the template is completed, the swing seat 1 drives the cardboard away from the template by swinging. At this time, several support parts 21 can extend to move the cardboard away from the state of being attached to the swing seat 1. At this time, the worker can easily remove the molded cardboard from the swing seat 1. Then the four blocking strips 2 return to their initial state, and then the worker can put in a new cardboard, and so on.

[0029] Beneficial effects: Firstly, compared to existing technologies, the distance workers need to reach into the equipment when placing cardboard is significantly reduced, allowing workers to complete the cardboard placement operation in a safer manner;

[0030] Secondly, compared with existing technologies, after the cardboard is molded, it can be separated from the end face of the swing seat 1 due to the reset of the blocking strip 2. This makes it easier for workers to remove the molded cardboard from the equipment, effectively avoiding the situation where the cardboard is not removed due to being squeezed and is then molded by the equipment again. It also shortens the time for workers to remove the cardboard.

[0031] like Figures 1 to 3 As shown, in order to make the cardboard more stable when falling along each support 21, the angle between the upper end face of several support 21 and the ground gradually decreases from top to bottom, that is, to ensure that the lower end face of the cardboard can fall into the next support 21 with one end first. In addition, in order to ensure that the lower end face of the cardboard can fit the support 21 when the side of the cardboard fits the end face of the swing seat 1, the upper end face of the support 21 is perpendicular to the end face of the swing seat 1 where the fitting groove 11 is opened.

[0032] like Figures 2 to 4 As shown, specifically, both ends of the blocking bar 2 are fixedly provided with connecting rods 22, and the swing seat 1 is provided with a receiving groove 12 that connects to the fitting groove 11. The driving assembly includes two sets of motors 4 with one end fixedly provided in the swing seat 1, and a pusher connected to the other end of the motor 4. The motor 4 is used to drive the pusher to abut against the connecting rod 22 until the connecting rod 22 slides into the receiving groove 12.

[0033] like Figures 3 to 5 As shown, the pusher includes several irregularly shaped wheels 3 coaxially connected to the motor 4. The periphery of the irregularly shaped wheel 3 includes a limiting part 31 and a relief part 32 that can form a closed ring surface. The outer contour diameter of the limiting part 31 is larger than the outer contour diameter of the relief part 32. The irregularly shaped wheel 3 has a rounded corner structure formed between the limiting part 31 and the relief part 32 for transition. When the limiting part 31 abuts against the connecting rod 22, it can push the connecting rod 22 to slide into the receiving groove 12 in a direction away from the axis of the irregularly shaped wheel 3 and position it. Until the relief part 32 is attached to the surface of the connecting rod 22, the support part 21 slides out of the fitting groove 11. In this specific embodiment, the central angle of adjacent limiting parts 31 decreases by the same angle from top to bottom, that is, the time interval between each blocking bar 2 retracting into the fitting groove 11 is the same.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
