Description

Technical Field

[0001] This application relates to cartoning machine equipment technology, and more particularly to an auxiliary pressing device for a cartoning machine and a cartoning machine. Background Technology

[0002] Cartoning machines are widely used in industrial production fields such as food, medicine, and daily chemicals.

[0003] In related technologies, a cartoning machine includes a conveying hopper, a pushing mechanism, and a turntable suction box mechanism. The operator puts the product material into the conveying hopper. After the product material is conveyed to the designated position by the conveying hopper, it is pushed into the packaging box of the turntable suction box mechanism by the pushing mechanism. After the cartoning is completed, the packaged product is sent out.

[0004] However, the product materials in the conveyor hopper are prone to uneven stacking, wrinkles, or bending. If the pushing mechanism directly pushes the product materials, it can easily cause the product materials to jam or break, affecting the product yield. Utility Model Content

[0005] This application provides an auxiliary pressing device and a cartoning machine to solve the technical problem in the related art that product materials in the cartoning machine are easily jammed or damaged.

[0006] This application provides an auxiliary pressing device for a cartoning machine, including:

[0007] The support body includes legs and mounting brackets on the legs, the legs being used to connect to the main body of the cartoning machine;

[0008] A pressure plate is movably connected to the mounting bracket. The pressure plate is configured to move vertically relative to the mounting bracket in the height direction under the action of an external force, and when it moves downward relative to the mounting bracket, it extends into the conveying hopper of the cartoning machine to press the product material in the conveying hopper.

[0009] In some possible implementations, a drive member is also included, which is connected to the mounting bracket. The drive member has a drive end that extends and retracts in the height direction and is connected to the pressure plate to drive the pressure plate to displace relative to the mounting bracket.

[0010] In some possible implementations, the pressure plate is provided with at least two spaced mounting holes, and the pressure plate is connected to the drive end through a positioning member passing through the mounting holes;

[0011] The two mounting holes are arranged symmetrically with respect to the center of the pressure plate.

[0012] In some possible implementations, the mounting hole is a strip-shaped hole, and the driving component is a cylinder or an electric push rod.

[0013] In some possible implementations, the support legs are two in number, with the two support legs positioned on opposite sides of the conveying hopper, and the mounting bracket is provided with a mounting plate for mounting the drive component.

[0014] In some possible implementations, the pressure plate is a rectangular plate, and an elastic layer is provided on the side of the pressure plate opposite to the driving end.

[0015] In some possible implementations, the elastic layer is at least one of a silicone layer, a polyurethane layer, and a foam layer.

[0016] In some possible implementations, a buffer plate is also included, which is disposed on the side of the pressure plate opposite to the drive end, and the buffer plate is elastically connected to the pressure plate;

[0017] The buffer plate is a silicone plate or a polyurethane plate.

[0018] In some possible implementations, the pressure plate is provided with at least two elastic elements on the side opposite to the driving end. The elastic elements are connected to the buffer plate and have an elastic force that drives the buffer plate to displace in a direction opposite to the pressure plate.

[0019] On the other hand, embodiments of this application also provide a cartoning machine, including a device body, wherein the device body is provided with an auxiliary pressing device for the cartoning machine as described in any of the preceding claims.

[0020] The auxiliary pressing device and cartoning machine provided in this application embodiment have a support body installed on the cartoning machine in the related technology via support legs, which does not require any structural modification to the cartoning machine and has strong versatility.

[0021] Furthermore, the pressure plate is configured to move vertically relative to the mounting bracket in the height direction under the action of external force. When it moves downward relative to the mounting bracket, it extends into the conveyor hopper of the cartoning machine to press the product material in the conveyor hopper. Thus, the pressure plate can apply pressure to the product material vertically and evenly, effectively eliminating gaps and wrinkles between the product materials, so that the product material is flat and compacted in the conveyor hopper. When it is subsequently pushed into the packaging box by the pushing mechanism, the stacked product material is stably formed, avoiding the problem of jamming caused by the product material being messy during the pushing process, which helps to ensure the smooth operation of the production process.

[0044] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application.

[0046] like Figure 2 As shown, the cartoning machine in the related technology includes a conveying bin 600, a pushing mechanism 700, and a turntable suction mechanism 800. The operator puts the product material into the conveying bin 600. After the product material is conveyed to the designated position by the conveying bin 600, it is pushed from one side by the pushing mechanism 700 into the packaging box of the turntable suction mechanism 800. After the cartoning is completed, the packaged product is sent out.

[0047] During the manual placement of the conveyor hopper 600, errors in human operation, such as touching the product material with fingers or varying placement force, can cause the product material to shift. This can lead to uneven stacking of the product material within the conveyor hopper 600. Since the stacking state of each conveyor hopper 600 is different, when the subsequent pushing mechanism 700 directly pushes the product material from the conveyor hopper 600, the product material can easily interfere with the packaging box of the turntable suction box mechanism 800, causing jamming malfunctions.

[0048] Based on the above description, one or more embodiments of this application provide an auxiliary pressing device for a cartoning machine and a cartoning machine.

[0049] In the auxiliary pressing device of the cartoning machine, the pressure plate 200 applies pressure vertically and evenly to the product material, effectively eliminating gaps and wrinkles between the product materials. This allows the product materials to be flattened and compacted in the conveying hopper 600. When the product materials are subsequently pushed towards the packaging box by the pushing mechanism 700, the stacked product materials are stably formed, avoiding jamming caused by disordered product materials during the pushing process, which helps to ensure the smooth progress of the production process.

[0050] The following description, in conjunction with the accompanying drawings, illustrates the solutions of the embodiments of this application.

[0051] like Figure 1 and Figure 3As shown in the figure, this application embodiment provides an auxiliary pressing device for a cartoning machine, including a support body 100 and a pressing plate 200. The support body 100 includes a support leg 101 and a mounting bracket 102 disposed on the support leg 101. The support leg 101 is used to connect with the equipment body 500 of the cartoning machine. The pressing plate 200 is movably connected to the mounting bracket 102. The pressing plate 200 is configured to move up and down relative to the mounting bracket 102 in the height direction under the action of external force, and when it moves down relative to the mounting bracket 102, it extends into the conveying hopper 600 of the cartoning machine to press the product material in the conveying hopper 600.

[0052] In the above embodiments, the product material can be strip-shaped materials such as cat treats, milk powder bars, or coffee liquid bars, or small bagged packaging materials such as milk powder bags or nut bags. The cartoning machine adopts the semi-automatic cartoning machine equipment in related technologies. For the conveying hopper 600, the pushing mechanism 700, and the turntable suction mechanism 800 mentioned in the embodiments of this application, the components of the cartoning machine in related technologies can be set up, and will not be described again in the embodiments of this application.

[0053] like Figure 3 As shown, the auxiliary pressing device of the cartoning machine in this embodiment of the application further includes a driving component 300. The driving component 300 is connected to the mounting bracket 102. The driving component 300 has a driving end 301 that extends and retracts along the height direction. The driving end 301 is connected to the pressure plate 200 to drive the pressure plate 200 to move relative to the mounting bracket 102.

[0054] For example, the driving component 300 is a cylinder or an electric push rod. When the driving component 300 is a cylinder, the piston rod of the cylinder constitutes the driving end 301 that extends and retracts in the height direction. When the driving component 300 is an electric push rod, the movable end of the lead screw of the electric push rod is the driving end 301.

[0055] Linear guiding mechanisms such as cylinders or electric push rods ensure the vertical movement trajectory of the pressure plate 200, enabling the pressure plate 200 to accurately enter the conveying hopper 600 and preventing the pressure plate 200 from tilting and interfering with or rubbing against the side wall of the conveying hopper 600.

[0056] After the product material is placed in the conveying hopper 600, the driving end 301 of the driving component 300 drives the pressure plate 200 to move down. After the pressure plate 200 finishes pressing the product material, the driving end 301 retracts and drives the pressure plate 200 to move up, preparing for the next pressing operation of the conveying hopper 600.

[0057] Preferably, the drive component 300 is a cylinder. The cylinder has a stable output force and rapid action, providing continuous and uniform downward pressure, ensuring the consistency of the pressing effect of the pressure plate 200 each time. At the same time, by adjusting the air pressure in the cylinder's air circuit, the pressing force of the pressure plate 200 can be adjusted accordingly to adapt to products of different materials and specifications, thus having strong versatility.

[0058] Furthermore, the pressure plate 200 is provided with at least two spaced mounting holes, and the pressure plate 200 is connected to the drive end 301 through a positioning member passing through the mounting holes; the two mounting holes are arranged symmetrically with respect to the center of the pressure plate 200.

[0059] In the above embodiment, the two mounting holes are located in the middle of the pressure plate 200, and the positioning components are bolts or pins. The symmetrical arrangement of the two points ensures that the downward pressure on the pressure plate 200 from the driving end 301 is uniform, preventing the pressure plate 200 from warping or deforming when pressing the product material, and helping to ensure that the product material is pressed flat and consistent.

[0060] like Figure 4 As shown, for example, a metal plate 201 is provided on the side of the pressure plate 200 away from the drive end 301. The size of the metal plate 201 is smaller than that of the pressure plate 200, as long as it can accommodate two positioning members. The positioning members pass through the through hole 202 reserved on the metal plate 201 and the mounting hole on the pressure plate 200 in sequence, and are fixedly connected to the drive end 301.

[0061] The metal plate 201 can be made of stainless steel or carbon steel. This design can distribute the preload when the positioning element is fastened to the pressure plate 200 onto the metal plate 201, preventing the pressure plate 200 from cracking or deforming due to stress concentration around the mounting hole. In addition, during the process of the drive end 301 driving the pressure plate 200 to move down and press, the impact load of the drive end 301 on the pressure plate 200 is dispersed by the metal plate 201, which can also ensure the stable and reliable connection between the pressure plate 200 and the drive end 301.

[0062] In this embodiment, the mounting hole is a strip-shaped hole. After the positioning member passes through the mounting hole, it is initially pre-tightened with the drive end 301. The relative position of the pressure plate 200 on the drive end 301 can be adjusted accordingly, which makes it easier to adjust the pressure plate 200 to align with the conveying hopper 600, and the installation and debugging process is more convenient.

[0063] It should be noted that the time and interval of the up and down displacement of the drive component 300 and the drive pressure plate 200 in the embodiments of this application can be set according to the conveying speed of the conveying bin 600. When the conveying bin 600 regularly passes through the auxiliary pressing device, the drive component 300 drives the pressure plate 200 to perform a pressing action on each conveying bin 600 that passes through in sequence.

[0064] For example, the auxiliary pressing device of the cartoning machine in this application embodiment further includes a detection component and a control component, the detection component is connected to the control component, and the control component is connected to the drive component 300.

[0065] The detection component is located upstream of the conveying hopper 600 of the equipment body 500. The detection position of the detection component is aligned with the path of the conveying hopper 600. When the conveying hopper 600 is conveying, the detection component detects the conveying hopper 600 and sends a detection signal to the control module. The control module sends a trigger signal to control the drive component 300 to drive the pressure plate 200 to press down. After the pressure plate 200 completes the pressing action, it moves up to reset and waits for the next trigger signal from the control module.

[0066] Here, the detection component can be a photoelectric sensor or a proximity switch from the related technology, and the control component can be a programmable logic controller from the related technology.

[0067] With the above settings, the pressure plate 200 will only perform the pressing action when the detection component detects that the conveyor hopper 600 has passed by. Therefore, the problem of pressure plate 200 being under pressure or leaking pressure can be avoided.

[0068] like Figure 1 and Figure 3 As shown, in some embodiments, there are two legs 101, which are respectively placed on both sides of the conveying bin 600, and the mounting bracket 102 is provided with a mounting plate 103 for mounting the drive component 300.

[0069] Here, the support leg 101 is provided with a strip-shaped positioning hole, and the equipment body 500 is fixedly connected to it by bolts passing through the positioning hole. The strip-shaped positioning hole facilitates the adjustment of the position of the support leg 101 relative to the equipment body 500, thereby facilitating the fine adjustment of the position of the auxiliary pressing device on the production line.

[0070] The mounting bracket 102 and the two support legs 101 form a gate-shaped structure. This arrangement can enhance the stability of the auxiliary pressing device during the pressing process and prevent vibration and shaking when the pressure plate 200 is pressed down.

[0071] The mounting plate 103 on the mounting bracket 102 is a flat metal plate 201. The mounting plate 103 is fixed to the mounting bracket 102 by welding or bolting and is located between the two support legs 101. The mounting plate 103 is provided with standard holes for corresponding fixing of the driving component 300. The driving component 300 is fixed to the mounting plate 103 by bolts passing through the standard holes.

[0072] Here, the support leg 101 and the mounting bracket 102 can be made of aluminum alloy, carbon steel or other stainless steel. The support leg 101 is detachably connected to the equipment body 500, which facilitates the disassembly and assembly of the auxiliary pressing device, making the application scenarios and positions of the auxiliary pressing device more flexible and versatile.

[0073] In this embodiment, the conveying hopper 600 is a rectangular hopper, the pressure plate 200 is a rectangular plate, and the side of the pressure plate 200 facing the conveying hopper 600 is provided with an elastic layer.

[0074] For example, the elastic layer is at least one of a silicone layer, a polyurethane layer, and a foam layer.

[0075] The elastic layer covers the pressing area of ​​the pressure plate 200 and is fixed to the pressure plate 200 by adhesive bonding, inlay process or vulcanization process.

[0076] The elastic layer is the layer that comes into direct contact with the product material. The elastic layer can adapt to uneven product material surfaces, eliminate wrinkles and gaps between multiple product materials, and ensure the flatness of the product material.

[0077] In addition, because the elastic layer has a certain elastic deformation property, it can buffer rigid impacts and prevent the pressure plate 200 from rigidly pressing the product material, thereby avoiding obvious creases, punctures or damage to the contents of the product material.

[0078] The downward movement height of the pressure plate 200 can be set according to factors such as the size of the packaging box and the depth of the conveying hopper 600, as long as the maximum height of the product material after pressing is less than the size of the packaging box.

[0079] like Figure 5 As shown, as an alternative implementation, the auxiliary pressing device of the cartoning machine also includes a buffer plate 400. The buffer plate 400 is located on the side of the pressure plate 200 away from the drive end 301, and the buffer plate 400 is elastically connected to the pressure plate 200. The buffer plate 400 is a silicone plate or a polyurethane plate.

[0080] For example, the pressure plate 200 is provided with at least two elastic elements 401 on the side away from the drive end 301. The elastic elements 401 are connected to the buffer plate 400 and have an elastic force that drives the buffer plate 400 to move in the direction away from the pressure plate 200.

[0081] The aforementioned buffer plate 400 is made of elastic deformable material, and the size of the buffer plate 400 is equivalent to the pressing surface size of the pressure plate 200, so as to ensure that it can fully cover the product material in the conveying hopper 600.

[0082] In some embodiments, there are multiple elastic elements 401. For example, one elastic element 401 is provided around the buffer plate 400. The two ends of the elastic element 401 are connected to the pressure plate 200 and the buffer plate 400 by spot welding or bonding. By providing elastic elements 401 around the buffer plate 400, the buffer plate 400 maintains a stable horizontal posture in both the free state and the vertical displacement state, preventing excessive displacement of the buffer plate 400 due to local force.

[0083] When the stack height of the product materials in contact with the buffer plate 400 is uneven, multiple independent elastic elements 401 can make different areas of the buffer plate 400 perform independent small elastic displacements.

[0084] For example, when one end of the buffer plate 400 presses against a higher material, the elastic element 401 at that end is compressed more, while the elastic element 401 at the other end is compressed less. This allows the buffer plate 400 to dynamically adapt to the irregularity of the material surface, achieve a uniform pressure effect, and ensure a high degree of consistency in the pressing quality.

[0085] During the downward movement of the buffer plate 400 along with the pressure plate 200, if the stacking of the product materials is uneven and the local protrusions are large, the buffer plate 400 can elastically contract through the elastic element 401 to adapt to the height difference of different product materials. It provides better protection for fragile and easily damaged product materials and avoids the pressure plate 200 directly pressing down, which would cause relatively protruding product materials to be crushed.

[0086] Here, the elastic element 401 can be a flexible spring, and the elastic potential energy of the elastic element 401 is set according to the fragility of the product material.

[0087] For example, the more easily the product material is crushed, the less elastic the elastic element 401 is. When the buffer plate 400 moves down and touches the product material, the elastic element 401 is more easily compressed. Here, the fragile and easily damaged product material can be materials such as biscuits or medicines.

[0088] It should be noted that for the product materials pressed under the buffer plate 400, elastic elements 401 with different elastic strengths can be flexibly selected for products with different degrees of fragility. The stacked product materials after pressing do not need to be at the same horizontal height, as long as it ensures that the pressed product materials can smoothly and without interference enter the subsequent packaging box.

[0089] Of course, after setting the buffer plate 400, the pressure plate 200 does not directly contact the product material, so the elastic layer on the pressure plate 200 can be omitted.
