Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, and specifically relates to a conveying device for food packaging processing. Background Technology

[0002] In the industrial food production process, coding is typically applied to the surface of finished food packaging boxes for product traceability and quality management. Current technology generally integrates a coding machine onto a conveyor, continuously transporting the boxes to the coding station for coding. The coded boxes then fall directly to a collection area via the conveyor's discharge end. However, this approach has significant drawbacks in practical applications. Because food packaging boxes are quite heavy, and the food materials inside (such as glass bottles, metal cans, or high-density filled products) are usually of high mass, the boxes experience a significant impact acceleration due to gravity when falling freely from the conveyor's discharge end. Experimental tests have shown that this peak impact force can reach 3-5 times the total mass of the packaging box. This instantaneous impact can easily cause the food inside the box to break, deform, or fail to seal properly, leading to quality problems. Especially for fragile foods (such as puffed foods and baked goods) or liquid products (such as juice and dairy products), the violent shaking and collision caused by the impact during the fall of the packaging box may damage the internal food structure.

[0003] In summary, the existing technology has the following problems:

[0004] When the packaging box falls from the discharge end of the conveyor, due to the weight of the packaging box and the high density of the food material inside, a large impact acceleration will be generated, which will cause damage to the food inside the packaging box. Utility Model Content

[0005] In view of this, the present invention provides a conveying device for food packaging processing to solve the problem in the prior art that when the packaging box falls from the discharge end of the conveyor, the packaging box itself and the high density of the food material inside will generate a large impact acceleration, which will cause damage to the food inside the packaging box.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A conveying device for food packaging processing includes a conveyor, a discharge plate is inclinedly arranged below the discharge end of the conveyor, a hinge shaft is fixedly connected to the discharge plate, the hinge shaft is rotatably connected to the conveyor, and an elastic support device is provided on the hinge shaft. The elastic support device elastically connects the hinge shaft to the conveyor, and the elastic support device will undergo elastic deformation when subjected to external force.

[0008] In this technical solution, it should be noted that the conveyor utilizes existing technology, including a mounting frame and a conveyor belt. The conveyor belt is mounted on the mounting frame, and the hinge shaft is rotatably connected to the mounting frame. An elastic support device is used to support the discharge plate. The conveyor mounting frame is made of high-strength aluminum alloy, with dimensions of 2000 mm long, 800 mm wide, and 1000 mm high. The conveyor belt is made of food-grade PVC, 3 mm thick, with an anti-slip textured surface. The discharge plate is tilted below the discharge end of the conveyor and is made of food-grade stainless steel, 3 mm thick. The hinge shaft is made of high-strength carbon steel, with a precision-machined and corrosion-resistant surface. In the initial state, the elastic support device holds the discharge plate in a slightly tilted position (tilt angle approximately 10°). At this time, the distance between the end of the discharge plate furthest from the conveyor and the ground is relatively large, ensuring a slow sliding speed of the packaging box on the discharge plate. When the packaging box falls from the conveyor onto the discharge plate, its weight exerts downward pressure on the plate. The elastic support device then undergoes elastic deformation, absorbing some of the impact force and reducing the instantaneous impact on the box. As the box lands on the discharge plate, the plate, under the weight of the box, gradually rotates downwards on the hinge shaft. The distance between the end of the discharge plate furthest from the conveyor and the ground gradually decreases, thus reducing the vertical height of the box's fall. In summary, this invention, through the elastic support device, discharge plate, and hinge shaft, ensures that after the box lands on the discharge plate, not only is some of the impact force buffered by the elastic support device, but the discharge plate also slowly rotates due to the box's weight, gradually shortening the distance between the plate and the ground, thereby reducing the vertical height of the box's fall and further reducing the likelihood of food damage inside the box.

[0009] Preferably, the elastic support device includes a transmission plate and an elastic element. One end of the transmission plate is fixedly connected to a hinge shaft, and the other end is connected to the elastic element. The end of the elastic element away from the transmission plate is connected to the conveyor. The elastic element is a tension spring, and its two ends are respectively connected to the conveyor and the transmission plate.

[0010] In this technical solution, it should be noted that the transmission plate is made of high-strength aluminum alloy with a thickness of 5 mm, ensuring good durability while transmitting force. The elastic element is a tension spring made of high-strength spring steel. When the packaging box falls onto the discharge plate, its weight is transmitted to the hinge shaft, causing the hinge shaft to rotate. The rotation of the hinge shaft drives the transmission plate to rotate, which in turn pulls the tension spring, causing it to elastically deform. The tension of the tension spring balances the weight of the packaging box, thereby controlling the rotation angle and speed of the discharge plate. As the packaging box continues to act, the tilt angle of the discharge plate gradually increases, and eventually, the packaging box slides off the discharge plate and falls into the collection box.

[0011] Preferably, a chute is provided on one side of the conveyor in the width direction, the chute is located above the transmission plate, and one end of the chute extends along the length direction of the conveyor to one side of the transmission plate, and a stop block that cooperates with the transmission plate is slidably embedded in the chute.

[0012] In this technical solution, it should be noted that the chute is made of high-strength aluminum alloy, and the stop is made of polyoxymethylene (POM), which has good self-lubricating properties and wear resistance. It fits tightly with the chute to ensure smooth and stable sliding. For packaging boxes that do not require this discharge plate cushioning method, such as lightweight packaging boxes, rigid packaging boxes, or packaging boxes containing impact-resistant food, the stop can be slid above the transmission plate to block the rotation of the transmission plate, thus preventing the discharge plate from rotating. This design not only improves the flexibility of the conveying device but also ensures the stability and reliability of the equipment under different packaging requirements. Specifically, lightweight packaging boxes, due to their light weight, will not generate significant impact even if dropped directly, thus requiring no cushioning. Using a cushioned drop method for these packaging boxes that do not require cushioning may have the following adverse effects: Equipment wear: Unnecessary cushioning increases wear on elastic components and the transmission plate, shortening the equipment's lifespan. This solution, by setting the stop, allows for flexible selection of whether to use a cushioned drop method, thus adapting to different types of packaging boxes and ensuring efficient operation of the equipment under various production needs. In operation, the operator can manually slide the stop block above the transmission plate, ensuring close contact between the stop block and the transmission plate, thus physically blocking the rotation of the transmission plate. This keeps the discharge plate in its initial slightly tilted state, preventing it from rotating due to the weight of the packaging boxes. This design not only improves the flexibility of the conveying device but also ensures the stability and reliability of the equipment under different packaging requirements.

[0013] Preferably, a first screw hole is provided through the stop block, and a bolt is screwed into the inner side of the first screw hole. A second screw hole that mates with the bolt is also provided in the slide groove, and the second screw hole is located above the transmission plate.

[0014] In this technical solution, it should be noted that in practical applications, the conveyor will generate vibrations during operation, which may cause the stop blocks to shift within the chute. Once the stop blocks move above the transmission plate, without effective securing measures, they may shift due to vibration, affecting the stability of the discharge plate. Therefore, the design employs a bolt and threaded hole combination to secure the stop blocks. Furthermore, to further enhance the stability of the stop blocks, elastic washers can be added between the bolts and the stop blocks to absorb some vibration energy and reduce the possibility of bolt loosening. Through this design, the conveyor can maintain stable operation under various working conditions, ensuring a smooth and reliable descent of the packaging boxes.

[0015] Preferably, baffles are provided on both sides of the discharge plate in the width direction, and the top of the baffles is higher than the top of the discharge plate.

[0016] In this technical solution, it should be noted that the baffle is made of food-grade stainless steel with a thickness of 2 mm, and its height is adjustable according to the size of the packaging box and the sliding requirements. The baffle is fixed to both sides of the discharge plate to ensure that it will not fall off during the sliding of the packaging box.

[0017] Preferably, the discharge plate is further provided with two guide rods, which are located on one side of the two baffles respectively, and the two guide rods are in a figure-eight shape. The end of the guide rod near the baffle is sleeved on the screw rod, which is fixed on the discharge plate. A nut is screwed onto the screw rod, and the nut is located above the guide rod.

[0018] In this technical solution, it's important to note that two guide rods are used to guide the sliding direction of the packaging box, ensuring its smooth descent. The guide rods are made of high-strength aluminum alloy with an anodized surface to improve wear and corrosion resistance. The end of the guide rod near the baffle is fitted onto a screw rod, which is made of stainless steel and fixed to the discharge plate. Nuts are screwed onto the screw rod to secure the position of the guide rod. Because the two guide rods are fitted onto the screw rod, they can rotate, allowing the operator to adjust the angle according to the size of the packaging box and the sliding requirements. During adjustment, the operator loosens the nut, rotates the guide rod to the appropriate position, and then tightens the nut to press the guide rod firmly in place. This design not only improves the flexibility of the conveying device but also ensures stable sliding of packaging boxes of different sizes, reducing problems such as packaging box damage or inaccurate descent caused by poor sliding.

[0019] Preferably, a washer is also fitted onto the screw, and the washer is located between the nut and the guide rod.

[0020] In this technical solution, it should be noted that the gasket is made of high-strength stainless steel, which effectively disperses the tightening force of the nut, preventing deformation or damage to the guide rod due to excessive local pressure. The gasket design not only enhances the stability of the connection but also effectively prevents the nut from loosening due to vibration during use, thus ensuring the guide rod's fixation. Furthermore, the smooth surface of the gasket reduces friction between the nut and the guide rod, extending the service life of the components.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, by setting an elastic support device, a discharge plate and a hinge shaft, after the packaging box falls onto the discharge plate, not only can the elastic support device buffer part of the impact force, but the discharge plate will also rotate slowly due to the weight of the packaging box, so that the distance between the discharge plate and the ground gradually shortens, thereby reducing the vertical height of the packaging box when it slides down, and further reducing the chance of damage to the food inside the packaging box.

[0023] 2. In this utility model, by setting a stop, the use of a buffer drop method can be flexibly selected to adapt to different types of packaging boxes and ensure the efficient operation of the equipment under various production needs.

[0024] 3. In this utility model, the figure-eight structure of the guide rod can effectively guide the sliding direction of the packaging box and ensure that it remains centered on the discharge plate. Attached Figure Description

[0040] Example 1

[0041] like Figures 1-7As shown, this embodiment proposes a conveying device for food packaging processing, including a conveyor 100. A discharge plate 200 is inclinedly arranged below the discharge end of the conveyor 100. A hinge shaft 300 is fixedly connected to the discharge plate 200, and the hinge shaft 300 is rotatably connected to the conveyor 100. An elastic support device is provided on the hinge shaft 300, which elastically connects the hinge shaft 300 to the conveyor 100, and undergoes elastic deformation when subjected to external force. It should be noted that the conveyor 100 adopts existing technology, including a mounting frame 101 and a conveyor belt 102. The conveyor belt 102 is mounted on the mounting frame 101, and the hinge shaft 300 is rotatably connected to the mounting frame 101. The elastic support device is used to support the discharge plate 200. The mounting frame 101 of the conveyor 100 is made of high-strength aluminum alloy, with dimensions of 2000 mm in length, 800 mm in width, and 1000 mm in height. The conveyor belt 102 is made of food-grade PVC, with a thickness of 3 mm and an anti-slip texture on the surface. The discharge plate 200 is inclined and positioned below the discharge end of the conveyor 100, made of food-grade stainless steel with a thickness of 3 mm. The hinge shaft 300 is made of high-strength carbon steel, with a precision-machined and corrosion-resistant surface. In the initial state, the elastic support device holds the discharge plate 200 in a slightly inclined state (inclination angle of approximately 10°). At this time, the distance between the end of the discharge plate 200 away from the conveyor 100 and the ground is relatively large, ensuring that the sliding speed of the packaging box on the discharge plate 200 is slow. When the packaging box falls from the conveyor 100 onto the discharge plate 200, the weight of the packaging box will exert downward pressure on the discharge plate 200. The elastic support device begins to elastically deform, absorbing part of the impact force and reducing the instantaneous impact on the packaging box. As the packaging box falls onto the discharge plate 200, the discharge plate 200, under the weight of the packaging box, gradually rotates downwards on the hinge shaft 300. The distance between the end of the discharge plate 200 away from the conveyor 100 and the ground gradually shortens, thereby reducing the vertical height of the packaging box when it falls. In summary, in this utility model, through the provided elastic support device, discharge plate 200, and hinge shaft 300, after the packaging box falls onto the discharge plate 200, not only can the elastic support device buffer part of the impact force, but the discharge plate 200 will also slowly rotate due to the weight of the packaging box, causing the distance between the discharge plate 200 and the ground to gradually shorten, thereby reducing the vertical height of the packaging box when it falls, and further reducing the probability of damage to the food inside the packaging box.

[0042] like Figure 3 and Figure 4As shown, in this embodiment, the elastic support device includes a transmission plate 400 and an elastic element 401. One end of the transmission plate 400 is fixedly connected to the hinge shaft 300, and the other end is connected to the elastic element 401. The end of the elastic element away from the transmission plate 400 is connected to the conveyor 100. The elastic element 401 is a tension spring, and its two ends are connected to the conveyor 100 and the transmission plate 400, respectively. It should be noted that the transmission plate 400 is made of high-strength aluminum alloy with a thickness of 5 mm to ensure good durability while transmitting force. The elastic element 401 is a tension spring made of high-strength spring steel. When the packaging box falls onto the discharge plate 200, the weight of the packaging box is transmitted to the hinge shaft 300 through the discharge plate 200, and the hinge shaft 300 rotates accordingly. The rotation of the hinge shaft 300 drives the transmission plate 400 to rotate, and the rotation of the transmission plate 400 pulls the tension spring, causing it to undergo elastic deformation. The tension of the spring balances the weight of the packaging box, thereby controlling the rotation angle and speed of the discharge plate 200. As the packaging box continues to move, the tilt angle of the discharge plate 200 gradually increases, and eventually, the packaging box slides off the discharge plate 200 and falls into the collection box.

[0043] Example 2

[0044] like Figure 3 and Figure 4As shown, this embodiment is largely the same as the above embodiment, except that a chute 500 is provided on one side of the conveyor 100 in the width direction. The chute 500 is located above the transmission plate 400, and one end of the chute 500 extends along the length direction of the conveyor 100 to one side of the transmission plate 400. A stop 501 that cooperates with the transmission plate 400 is slidably embedded in the chute 500. It should be noted that the chute 500 is made of high-strength aluminum alloy, and the stop 501 is made of polyoxymethylene (POM), which has good self-lubricating properties and wear resistance. It fits tightly with the chute 500 to ensure smooth and stable sliding. For some packaging boxes that do not require this discharge plate 200 cushioning method, such as lightweight packaging boxes, rigid packaging boxes, or packaging boxes with impact-resistant internal food, the stop 501 can be slid above the transmission plate 400 to block the rotation direction of the transmission plate 400, thereby preventing the discharge plate 200 from rotating. This design not only improves the flexibility of the conveying device but also ensures the stability and reliability of the equipment under different packaging requirements. Specifically, lightweight packaging boxes, due to their light weight, will not generate significant impact even when dropped directly, thus eliminating the need for cushioning. Using a cushioned drop mechanism for these boxes, which does not require cushioning, could have the following negative effects: Equipment wear: Unnecessary cushioning increases wear on the elastic element 401 and the transmission plate 400, shortening the equipment's lifespan. This solution, by setting a stop 501, allows for flexible selection of whether to use a cushioned drop mechanism, adapting to different types of packaging boxes and ensuring efficient operation of the equipment under various production demands. In operation, the operator can manually slide the stop 501 above the transmission plate 400, ensuring close contact between the stop 501 and the transmission plate 400, thus physically blocking the rotation direction of the transmission plate 400. This keeps the discharge plate 200 in its initial slightly tilted state, preventing rotation due to the weight of the packaging boxes. This design not only improves the flexibility of the conveying device but also ensures the stability and reliability of the equipment under different packaging requirements.

[0045] like Figure 4As shown in this embodiment, a first threaded hole is provided through the stop block 501, and a bolt 502 is threaded into the inner side of the first threaded hole. A second threaded hole 503, which mates with the bolt 502, is also provided in the slide groove 500, located above the transmission plate 400. It should be noted that in practical applications, the conveyor 100 will vibrate during operation, which may cause the stop block 501 to shift within the slide groove 500. When the stop block 501 moves above the transmission plate 400, without effective fixing measures, it may move due to vibration, thus affecting the stability of the discharge plate 200. Therefore, the design uses the combination of bolt 502 and threaded hole to fix the stop block 501. Furthermore, to further enhance the stability of the stop block 501, an elastic washer can be added between the bolt 502 and the stop block 501 to absorb some vibration energy and reduce the possibility of the bolt 502 loosening. Through this design, the conveying device can maintain stable operation under various working conditions, ensuring a smooth and reliable descent of the packaging box.

[0046] Example 3

[0047] like Figure 5 As shown, this embodiment is largely the same as the previous embodiment, except that baffles 201 are provided on both sides of the discharge plate 200 in the width direction, and the top of the baffles 201 is higher than the top of the discharge plate 200. It should be noted that the baffles 201 are made of food-grade stainless steel, with a thickness of 2 mm, and their height is adjusted according to the size of the packaging box and the sliding requirements. The baffles are fixed to both sides of the discharge plate 200 to ensure that they will not fall off during the sliding of the packaging box.

[0048] like Figure 6 and Figure 7As shown, in this embodiment, the discharge plate 200 is further provided with two guide rods 202. The two guide rods 202 are located on one side of the two baffles 201, and the two guide rods 202 have a figure-eight structure. The end of the guide rod 202 near the baffle 201 is sleeved on a screw 203. The screw 203 is fixed to the discharge plate 200, and a nut 204 is screwed onto the screw 203, with the nut 204 located above the guide rod 202. It should be noted that the guide rods 202 are used to guide the sliding direction of the packaging box, ensuring its smooth descent. The guide rods 202 are made of high-strength aluminum alloy, and the surface is anodized to improve wear resistance and corrosion resistance. The end of the guide rod 202 near the baffle 201 is sleeved on the screw 203, which is made of stainless steel and fixed to the discharge plate 200. A nut 204 is screwed onto the screw 203 to fix the position of the guide rods 202. Since the two guide rods 202 are sleeved on the screw 203, they can rotate, allowing the operator to adjust the angle according to the size of the packaging box and the sliding requirements. During adjustment, the operator loosens the nut 204, rotates the guide rod 202 to the appropriate position, and then tightens the nut 204 to press the guide rod 202 firmly into place. This design not only improves the flexibility of the conveying device but also ensures stable sliding of packaging boxes of different sizes, reducing problems such as packaging box damage or inaccurate descent caused by poor sliding.

[0049] like Figure 7 As shown, in this embodiment, a washer 205 is also fitted onto the screw 203, and the washer 205 is located between the nut 204 and the guide rod 202. It should be noted that the washer 205 is made of high-strength stainless steel, which can effectively disperse the clamping force of the nut 204 and prevent deformation or damage to the guide rod 202 due to excessive local pressure. The design of the washer 205 not only enhances the stability of the connection but also effectively prevents the nut 204 from loosening due to vibration during use, thereby ensuring the fixing effect of the guide rod 202. Furthermore, the smooth surface of the washer 205 reduces friction between the nut 204 and the guide rod 202, extending the service life of the components.

[0050] The working principle of this utility model is as follows:

[0051] In the food packaging process, the workflow of this conveying device is as follows: The packaging box is first placed on the conveyor belt 102 of the conveyor 100, which smoothly transports the box to the discharge end. When the box reaches the discharge end, it falls onto the inclined discharge plate 200. The discharge plate 200 is rotatably connected to the conveyor 100 via a hinge shaft 300 and is initially slightly tilted (approximately 10°) by an elastic support device. The weight of the box is transferred to the hinge shaft 300 through the discharge plate 200. The hinge shaft 300 drives the transmission plate 400 to rotate, causing the transmission plate 400 to stretch a tension spring, resulting in elastic deformation that absorbs impact and reduces the instantaneous impact on the box.

[0052] As the packaging box continues to move, the discharge plate 200 gradually rotates downwards on the hinge shaft 300. The distance between the end of the discharge plate 200 away from the conveyor 100 and the ground gradually shortens, reducing the vertical height of the packaging box as it slides down. The guide rod 202 has a figure-eight structure, guiding the sliding direction of the packaging box and ensuring its smooth descent. At the same time, the baffle 201 prevents the packaging box from shifting laterally or falling.

[0053] For lightweight packaging boxes, the operator can slide the stop 501 above the transmission plate 400 to prevent the transmission plate 400 from rotating, keeping the discharge plate 200 in its initial tilted state without cushioning during descent. This design allows the device to adapt to different types of packaging boxes, ensuring they slide smoothly into the collection box, effectively reducing the chance of food damage, and improving the flexibility and reliability of the equipment.
