Description

Technical Field

[0001] This utility model relates to the field of cardboard box packaging equipment technology, and in particular to the structure of a protective shield device. Background Technology

[0002] A strapping machine is a device that uses strapping tape to bundle products or packages, then tightens the tape and joins the ends using a heat-sealing head. When working, the strapping machine is mainly used for packing cardboard boxes. Multiple cardboard boxes are stacked together to form a stack, which is then transported to the strapping station of the machine via a conveyor platform. When the cardboard boxes are stacked together for transport, the layers cannot be neatly stacked. Therefore, two openable baffles need to be installed at the front of the strapping station, and then at the rear of the strapping station... The system features split-opening aligning rods. When a cardboard box moves to the packing station, a baffle blocks the front of the stack of boxes. The boxes collide with the baffle during transport, aligning the stack front-to-back. Then, the aligning rods on both sides move simultaneously towards the boxes, aligning the stack laterally. Since the width of different cardboard boxes varies greatly depending on their size, the gap between the aligning rods and the baffle needs to be adjusted to accommodate different box sizes. However, in practice, human error can sometimes cause issues. If the position of the aligning rods and baffles is mistakenly left unadjusted, and the width of the carton exceeds the spacing between the two aligning rods when they converge, the rods will move towards the center after contacting the sides of the carton. The resistance of the carton will cause the aligning rods to generate a reaction force away from the carton. Since the aligning rods are usually welded to the mounting plate, if this reaction force persists due to prolonged misoperation, it can cause the welds between the aligning rods and the mounting plate to break, resulting in equipment damage. Similarly, If the baffles are not adjusted, they will lose their function as box-blocking devices. The baffles are installed on the uprights. If the distance between the two baffles is too large, when the two baffles are brought together towards the center, they cannot directly block the front of the stacked cartons. Instead, the stacked cartons will pass between the two baffles, and the two sides of the baffles will clamp the sides of the cartons. This will also cause the uprights to generate an external reaction force. Over time, this will also cause the welds between the uprights and the mounting plate to break. All of these factors will affect the integrated packing and box-binding equipment and cause damage. Utility Model Content

[0003] The purpose of this utility model is to avoid the shortcomings of the prior art and provide a structure for a protective shield device, thereby effectively solving the shortcomings of the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a structure for a protective blocking device, comprising a box-beating mechanism and a box-blocking mechanism symmetrically arranged on both sides of the frame of a packing and box-gathering integrated machine. The box-beating mechanism and the box-blocking mechanism are synchronously adjusted in distance through a drive mechanism on the frame. The box-beating mechanism is located on the rear side of the packing station, and the box-blocking mechanism is located on the front side of the packing station. The box-beating mechanism includes a first mounting plate connected to a first sliding seat on the frame. A swingable box-beating rod is connected to the lower part of the first mounting plate through a pin. The first mounting plates on both sides are provided with first outer plates at positions corresponding to the outer sides of their respective box-beating rods. A connecting spring is provided between the first outer plate and the box-beating rod, and the connecting spring keeps the box-beating rod vertical.

[0005] The baffle mechanism includes a second mounting plate connected to a second sliding seat on the frame. A swingable upright is connected to the lower part of the second mounting plate via a pin. A baffle is provided on the rear side of the upright. The two second mounting plates on both sides are provided with second outer plates at positions corresponding to the outer sides of their respective uprights. A connecting spring is provided between the second outer plate and the upright, and the connecting spring keeps the upright vertical.

[0006] Furthermore, both the first outer side plate and the second outer side plate are L-shaped structures. The horizontal plates of the two outer side plates are fixed to the first mounting plate and the second mounting plate, respectively. The vertical plates of the two outer side plates are located on the outside of the box-beating rod and the upright rod, respectively. There are gaps between the vertical plates of the two outer side plates and the box-beating rod and the upright rod, respectively. The connecting spring is set at the gap.

[0007] Furthermore, sensors are provided at the lower ends of the first outer side plate and the second outer side plate, with the sensor heads facing the side of the box-beating rod and the upright rod, respectively. The box-beating rod or the upright rod, in conjunction with the sensors, can control the drive mechanism on the frame to stop.

[0008] Furthermore, both sides of the first mounting plate and both sides of the second mounting plate are provided with a stop block on the opposite side of each other, and the stop block is respectively attached to the opposite side of the battering box rod and the upright rod.

[0009] Furthermore, the stop block is also an L-shaped structure, with the vertical part of the stop block fixedly connected to the first mounting plate and the second mounting plate, and the horizontal part of the stop block abutting against the side wall of the upper end of the box rod and the upright rod.

[0010] Furthermore, a first connecting plate is provided at the top of the box-making pole, and a second connecting plate is provided at the top of the upright pole.

The mounting plates are connected to the box-beating rod and the upright rod through connecting springs. When the equipment is misoperated and the box-beating rod and the upright rod come into contact with the carton and generate a reaction force, the box-beating rod and the upright rod will swing along the pin shaft, thereby realizing the force relief function and avoiding the box-beating rod and the upright rod from hard collision with the carton and causing the weld to break, thus avoiding damage to the equipment and extending the service life of the equipment.

[0015] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-2 As shown, the structure of the protective blocking device described in this embodiment includes a box-beating mechanism and a box-blocking mechanism symmetrically arranged on both sides of the frame of the integrated packing and box-gathering machine. The box-beating mechanism and the box-blocking mechanism are synchronously adjusted in distance by a drive mechanism on the frame. The box-beating mechanism is located on the rear side of the packing station, and the box-blocking mechanism is located on the front side of the packing station. The box-beating mechanism includes a first mounting plate 1 connected to a first sliding seat on the frame. A swingable box-beating rod 3 is connected to the bottom of the first mounting plate 1 through a pin 2. The first mounting plates on both sides are provided with a first outer plate 4 at the position corresponding to the outer side of their respective box-beating rods 3. A connecting spring 5 is provided between the first outer plate 4 and the box-beating rod 3. The connecting spring 5 keeps the box-beating rod 3 vertical.

[0018] The baffle mechanism includes a second mounting plate 6 connected to a second sliding seat on the frame. A swingable upright 7 is connected to the bottom of the second mounting plate 6 via a pin 2. A baffle 8 is provided on the rear side of the upright 7. Second outer plates 9 are provided on both sides of the second mounting plate 6 at positions corresponding to the outer sides of their respective uprights 7. A connecting spring 5 is provided between the second outer plate 9 and the upright 7, and the connecting spring 5 keeps the upright 7 vertical.

[0019] Both the first outer side plate 4 and the second outer side plate 9 are L-shaped structures. The horizontal plates of the two outer side plates are fixed on the first mounting plate 1 and the second mounting plate 6, respectively. The vertical plates of the two outer side plates are located on the outside of the box-beating rod 3 and the upright rod 7, respectively. There are gaps between the vertical plates of the two outer side plates and the box-beating rod 3 and the upright rod 7, respectively. The connecting spring 5 is set at the gap.

[0020] Sensors 10 are provided at the lower ends of the first outer side plate 4 and the second outer side plate 9. The sensing heads of the sensors 10 face the side of the box-tapping rod 3 and the upright rod 7, respectively. The box-tapping rod 3 or the upright rod 7 can cooperate with the sensors 10 to control the drive mechanism on the frame to stop.

[0021] Both sides of the first mounting plate 1 and the two sides of the second mounting plate 6 are provided with a stop block 11 on the opposite side of each other. The stop block 11 is respectively attached to the opposite side of the box rod 3 and the upright rod 7.

[0022] The stop block 11 is also an L-shaped structure. The vertical part of the stop block 11 is fixedly connected to the first mounting plate 1 and the second mounting plate 6 respectively, and the horizontal part of the stop block 11 abuts against the side wall of the upper end of the box rod 3 and the upright rod 7 respectively.

[0023] The stop block 11 prevents the box arm 3 or the upright arm 7 from deflecting to the opposite side.

[0024] The top of the box-shaped pole 3 is provided with a first connecting plate 12, and the top of the upright pole 7 is provided with a second connecting plate 13. The first connecting plate 12 and the second connecting plate 13 are respectively hinged to the first mounting plate 1 and the second mounting plate 6 through the pin 2.

[0025] The center of pin 2 corresponds to the inner side of the opposite side of the box-beating rod 3 or the upright rod 7. When the box-beating rod 3 or the upright rod 7 rotates, the two sides of the box-beating rod 3 or the upright rod 7 will swing with the opposite side as the radius, thus ensuring that the box-beating rod 3 or the upright rod 7 can rotate normally along the pin 2. When swinging, the lower end of the discharge rod 3 or the upright rod 7 will not contact the platform surface of the conveyor.

[0026] The lower end of the box-beating rod 3 is flush with the lower end of the upright rod 7, the lower end of the upright rod 7 is flush with the lower end of the baffle 8, the lower end of the first outer side plate 4 is flush with the lower end of the box-beating rod 3, the lower end of the second outer side plate 9 is flush with the lower end of the upright rod 7, and the connecting spring 5 is located at the lower part of the first outer side plate 4 and the second outer side plate 9 respectively.

[0027] The working principle of this utility model is as follows: The first mounting plate 1 and the second mounting plate 6 are respectively set on the slider of the drive mechanism on the frame. A utility model patent with patent number CN202222633234.2, entitled "A Power Device for Aligning Boxes of a Packing Machine," discloses a power device that can control the synchronous movement of the box-beating rods 3 and the baffles 8. That is, it controls the two side box-beating rods 3 or baffles 8 to simultaneously move towards the center of the equipment or simultaneously move away from each other. The formation of the power device can adjust the gap between the two side box-beating rods 3 or the two side baffles 8. When this device is working, stacks of cartons are first conveyed along the conveyor platform and transported to the packing station. At this time, the drive mechanism on the frame is activated and controls... The uprights 7 and the box-tapping rods 3 on both sides move simultaneously towards the stack of cardboard boxes. The baffles 8 on the uprights 7 block the front of the stack of cardboard boxes. The box-tapping rods 3 on both sides contact the sides of the stack of cardboard boxes and align them. If a worker makes a mistake, i.e., the width of the cardboard box exceeds the working gap between the box-tapping rods 3 or the baffles 8, the box-tapping rods 3 or the baffles 8 will contact the sides of the cardboard box and generate an outward reaction force. Driven by this reaction force, the box-tapping rods 3 or the uprights 7 will swing outward along the pin 2. During this swing, the box-tapping rods 3 or the uprights 7 will compress the connecting spring 5. The swing of the box-tapping rods 3 or the uprights 7 will dissipate the force, thus preventing a hard collision between the box-tapping rods 3 or the uprights 7 and the stack of cardboard boxes. This effectively prevents the box-tapping rod 3 or the upright rod 7 from breaking or cracking. If the working gap between the box-tapping rod 3 or the baffle 8 and the width of the carton are too large, the tilting angle of the box-tapping rod 3 or the upright rod 7 will also increase. At this time, the lower end of the box-tapping rod 3 or the upright rod 7 will contact the sensing end of the sensor 10 on the outer panel. The sensor is a proximity switch; after the sensor 10 is triggered, it will send a signal and control the drive mechanism of the entire equipment to stop. This protects the equipment and prevents further damage caused by excessive tilting angles of the box-tapping rod 3 or the upright rod 7. The box-packing machine can also be equipped with an alarm. When the sensor 10 is triggered, the alarm will sound simultaneously with the equipment stopping, thus alerting the staff to the equipment malfunction. In case of misoperation, after the staff readjusts the box-tapping rod 3 or the upright rod 7, the connecting spring 5 will cause the box-tapping rod 3 or the upright rod 7 to abut against the stop block 11, thus ensuring that the box-tapping rod 3 or the upright rod 7 remains vertical. After the box-tapping rod 3 or the upright rod 7 is adjusted, the stacked cartons can be aligned and blocked again. When the box-tapping rod 3 contacts the two sides of the stacked cartons, it will align the two sides of the cartons. During the alignment operation, since there is not much pressure between the stacked cartons, the box-tapping rod 3 only needs to generate a small force to push the cartons to move. At this time, the connecting spring 5 will generate a thrust to prevent the box-tapping rod 3 from shifting due to contact with the cartons, thus ensuring the normal operation of the carton alignment.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
