Description

Technical Field

[0001] The utility model relates to the field of equipment for pressing handles of carton boxes, in particular to a device for automatically pressing handles of carton boxes. Background Art

[0002] In the packaging industry, especially the food and beverage industry, cartons are often equipped with handles for consumers to carry easily. Existing handle pressing equipment usually uses linear guides to convey plastic handles. Since the friction coefficient between the plastic handle and the guide is small, its gravity easily causes the handle to slide up and down the linear guide, which will cause irregular movement of the handle when the cutter disc rotates, resulting in handle damage, waste, and affecting the accuracy and production efficiency of the press-fit handle. In order to solve this problem, a better way to convey the handle is needed. Summary of the invention

[0003] The utility model aims at the shortcomings of the prior art and provides a device for automatically pressing and installing a handle of a carton box.

[0004] To solve the above technical problems, the utility model is solved by the following technical solutions:

[0005] A carton box automatic press handle device comprises a carton conveying mechanism, a knife disc and a handle conveying device. The carton conveying mechanism is used to convey cartons. A handle pressing station is provided on the carton conveying mechanism. The knife disc is arranged above the handle pressing station. Cutters are evenly arranged at intervals in the circumference of the knife disc. The knife disc is connected to a knife disc power source for driving the rotation thereof. The handle conveying device is used to continuously convey connected handles. The handle conveying device comprises a front curved guide rail and a rear curved guide rail located outside the knife disc. The rear section of the front curved guide rail is connected with the rear curved guide rail to form at least one arc-shaped conveying path close to the knife disc. The part of the arc-shaped conveying path belonging to the front curved guide rail and the part belonging to the rear curved guide rail have opposite conveying directions in the horizontal direction. The curvature of the front curved guide rail and the rear curved guide rail is very close to the curvature of the knife disc, so that the angle of the handle output by the rear curved guide rail when in contact with the limit plate and the cutter of the knife disc is closer. The full contact avoids the situation that the knife disc rotates idly or the knife disc rotates a certain angle and the path of the handle roll is greater than the angle of the knife disc rotation.

[0006] Preferably, the angle of the arc conveying path corresponding to the center of the cutter disc is between 90° and 180°, so that the arc conveying path is surrounded by the cutter disc, the front curved guide rail is arc-shaped or reversely bent, and the length of the front curved guide rail is not less than the length of the rear curved guide rail. The weight of the handle material on the rear curved guide rail is not less than the weight of the handle on the front curved guide rail, which will pull the handle on the front curved guide rail from the rear and upper side of its movement direction, reducing the handle from sliding down due to its own weight, so that the movement of the handle is determined by the cutter disc, avoiding the cutter disc from idling without driving the handle, or the handle moving forward a distance greater than the distance covered by the angle of the cutter disc, so that the handle pressing position is more accurate and the yield rate is increased.

[0007] Preferably, a frame is also included, a fixed frame is provided on the frame, an adjusting frame is installed on the fixed frame, one of the top surface of the fixed frame and the bottom of the adjusting frame is provided with a limiting bevel, and the other is provided with an adjusting protrusion, and the limiting bevel and the adjusting protrusion cooperate with each other to enable the adjusting frame to be engaged with the fixed frame. Through the cooperation of the fixed frame and the adjusting frame, the design of the limiting bevel and the adjusting protrusion on the adjusting frame allows the equipment to be flexibly adjusted to adapt to handles and cartons of different specifications. The two can complete stable limiting fixation without the need for bolt locking, and the fixing with bolts is more stable. During the installation process, the limiting cooperation method makes the installation simpler, and there is no need to consider the left and right cost of the adjusting frame after aligning the holes, thereby achieving a more convenient installation effect and saving manpower.

[0008] Preferably, the adjustment frame is provided with a slide groove, in which an adjustable mounting side plate is installed, and the front curved guide rail, the rear curved guide rail and the cutter disc are all installed on the mounting side plate.

[0009] Preferably, a limiting plate for engaging with the handle is provided between every two adjacent cutters on the cutter disc, and the limiting plate can push the handle to move the material roll forward when the cutter disc rotates.

[0010] Preferably, a top block is provided below the handle pressing station, and the top block is driven by a top block power source to intermittently push out the plane of carton conveyance. The intermittent push-out action of the top block can accurately push out the pre-grooved part of the carton box, and then the handle can be accurately pressed into the part.

[0011] Preferably, the material turntable is further included for winding the handle material roll, and an elastic support is arranged below the material turntable. The elastic support is elastic in the vertical direction, and the top surface of the elastic support contacts the material turntable to provide resistance to the circumferential rotation of the material turntable. The elastic support arranged below the material turntable provides resistance to circumferential rotation, ensuring the stable operation of the material turntable, preventing the handle from being pulled out too much, and controlling the handle to be pulled out step by step.

[0012] Preferably, the handle conveying device further comprises a conveying bracket for lifting the handle output by the material turntable, and a dial wheel matching the shape of the handle is arranged on the inlet side of the conveying bracket.

[0013] Preferably, a conveying limit roller is arranged above the cutter disc, and the conveying limit roller is located at the entrance end of the front curved guide rail, and the front curved guide rail and the conveying bracket are connected by conveying through the conveying limit roller. The conveying limit roller is located at the entrance end of the front curved guide rail, ensuring a smooth transition of the handle from the conveying bracket to the guide rail.

[0014] Preferably, the front curved guide rail and the rear curved guide rail are formed between two inner and outer arc-shaped guide blocks, and the inner and outer guide blocks are arranged concentrically, so that the curvature of the formed front curved guide rail and the rear curved guide rail is close to the curvature of the curved surface of the cutter disc.

[0015] The utility model has significant technical effects due to the adoption of the above technical solutions:

[0016] The automatic press-fit handle device for cartons of the present invention adopts two guide rails in opposite directions, and uses the upper front curved guide rail to pull the handle on the rear curved guide rail, thereby basically eliminating the influence of the handle's own gravity. This design fully utilizes the limiter and blade of the knife disc to drive the handle to move forward in a step-by-step manner, effectively avoiding the problem of sliding down and cutting damage caused by the gravity of the handle, thereby significantly improving the yield rate and production efficiency. In addition, the design of the adjustment frame and the mounting side plate of the equipment provides good adjustability, so that the equipment can adapt to handles and cartons of different specifications, increasing the versatility and flexibility of the equipment.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1

[0025] A carton box automatic press handle device, such as Figure 1-3 As shown, it includes a carton conveying mechanism 1, a knife disc 2 and a handle conveying device. The carton conveying mechanism 1 is used to convey cartons. A handle pressing station is provided on the carton conveying mechanism 1. The knife disc 2 is arranged above the handle pressing station. Cutters 21 are evenly spaced around the knife disc 2. The knife disc 2 is connected to a knife disc power source for driving the rotation thereof. The handle conveying device is used to continuously convey connected handles. The handle conveying device includes a front curved guide rail 31 and a rear curved guide rail 32 located outside the knife disc 2. The rear section of the front curved guide rail 31 is connected to the rear curved guide rail 32 to form at least one arc-shaped conveying path close to the knife disc 2. The part of the arc-shaped conveying path belonging to the front curved guide rail 31 and the part belonging to the rear curved guide rail 32 have opposite conveying directions in the horizontal direction.

[0026] like Figure 4-5 As shown, the angle of the arc conveying path corresponding to the center of the cutter disc 2 is between 90°-180°, so that the arc conveying path is surrounded by the cutter disc 2, the front curved guide rail 31 is an arc shape or a reverse bend shape, and the length of the front curved guide rail 31 is not less than the length of the rear curved guide rail 32.

[0027] The machine frame further includes a fixing frame 41, on which an adjusting frame 42 is mounted. A top surface of the fixing frame 41 and a bottom surface of the adjusting frame 42 are provided with a limiting inclined groove 43, and the other of them is provided with an adjusting protrusion 44. The limiting inclined groove 43 and the adjusting protrusion 44 cooperate with each other to enable the adjusting frame 42 to be engaged with the fixing frame 41.

[0028] The adjustment frame 42 is provided with a slide groove 421 , and an adjustable mounting side plate 45 is installed in the slide groove 421 . The front curved guide rail 31 , the rear curved guide rail 32 , and the cutter disc 2 are all installed on the mounting side plate 45 .

[0029] Between every two adjacent cutters 21 on the cutter disc 2, a limiting piece 22 for engaging with the handle is provided. When the cutter disc 2 rotates, the limiting piece 22 can move the handle material roll forward.

[0030] A push block 51 is arranged below the pressing handle station. Driven by a push block power source, the push block 51 intermittently pushes out of the plane of carton conveyance. The push block power source can be a rotating shaft driven by a motor, one or more push blocks arranged on the rotating shaft, or one or more cams. Every time the rotating shaft rotates a certain angle, the push block is located at the position to be pushed out and pushes upward. Or the cam pushes up the push block.

[0031] It also includes a material turntable 61 for winding the handle material roll, and an elastic support member 62 is arranged below the material turntable 61. The elastic support member 62 is elastic in the vertical direction. The top surface of the elastic support member 62 contacts the material turntable 61 to provide resistance to the circumferential rotation of the material turntable 61.

[0032] The handle conveying device further includes a conveying bracket 33 for lifting the handle outputted from the material turntable 61 , and a thumbwheel 34 matching the shape of the handle is disposed on the inlet side of the conveying bracket 33 .

[0033] A conveying limit roller 35 is provided above the cutter disc 2 . The conveying limit roller 35 is located at the entrance end of the front curved guide rail 31 . The front curved guide rail 31 and the conveying bracket 33 are conveyed and connected via the conveying limit roller 35 .

[0034] The front curved guide rail 31 and the rear curved guide rail 32 are both formed between two inner and outer arc-shaped guide blocks 36, and the inner and outer guide blocks 36 are concentrically arranged.

[0035] Working principle:

[0036] The carton conveying mechanism 1 below conveys cartons or paper boxes at intervals, and the conveying method can be conveying by a conveyor belt, chain, or with a push block to push the carton box forward. On the other side, the handle wound on the material turntable 61 is pulled upward step by step through the dial wheel 34 on the front side of the conveying bracket 33. The friction force of the elastic support member 62 that hinders the rotation of the material turntable 61 can prevent the material turntable 61 from turning too far. The handle outputted at each rotation will not be hung between the conveying bracket and the material turntable 61, but will maintain a certain tension. The handle material on the conveying bracket 33 continues to be continuously conveyed forward, and after passing through the limiting roller 35, it enters the front curved guide rail 31 and the rear curved guide rail 32 in turn. The curvature of the front curved guide rail 31 and the rear curved guide rail 32 is very close to the curvature of the cutter disc 2, so that the handle outputted by the rear curved guide rail 32 can be closer to the limiting piece 22 and the cutter 21 of the cutter disc 2 when in contact. Full contact avoids the situation where the cutter disc rotates idly or the cutter disc rotates a certain angle and the path of the handle roll is greater than the angle of the cutter disc. The cutter cuts off the connection between the handles, the side of the handle is clamped and limited by the limit piece 22 on the knife disc 2, the top block 51 lifts the corresponding slotted seesaw on the carton, and the handle is clamped into the through hole generated after the carton seesaw is lifted; the lifted seesaw extends into the groove of the handle, and the carton continues to be fed, so that the handle will be clamped into the through hole in the slot below the carton seesaw. The specific structure of the handle is a well-known technology in the field, and it is not a technical problem to be solved by the present invention, so it will not be elaborated here.
