Description

Technical Field

[0001] This utility model relates to the field of pressing tooling technology, and in particular to synchronous pressing components. Background Technology

[0002] In the packaging process of bagged foods (such as bagged biscuits), a conveyor-pressing-boxing operation is required. The specific process is as follows: A conveyor belt is equipped with partitions. The bagged food is placed in a hopper between adjacent partitions for material transport. During the conveying process, a pressing plate presses the food down, while a pushing cylinder pushes it towards the box, achieving boxing. The pushing direction is perpendicular to the material conveying direction. The purpose of pressing is to reduce the thickness of the bagged food, allowing it to be pushed into the box properly. Pushing without pressing would cause the bagged food to bulge due to the pushing force, increasing its thickness and affecting boxing.

[0003] Currently, the pressing method uses a fixed plate with a curved, upturned front end to allow bagged food to smoothly and gently slide under the plate for pressing. However, the existing pressing plate has a problem: the lowest position of the pressing plate must be above the partition, meaning the minimum pressing height is the height of the partition. This prevents pressing operations at lower depths. For many small-quantity food packages or thin-walled boxes, the pressing cannot be completed as required, resulting in bagged food thickness exceeding the packaging box or the target thickness. The limited pressing distance also prevents thinner pressing as needed, which requires improvement.

[0004] Therefore, in view of the shortcomings of the above solution in actual production and implementation, it has been modified and improved. At the same time, in the spirit and concept of seeking the best, with the assistance of professional knowledge and experience, and after a lot of ingenuity and experimentation, a synchronous pressing component is specially provided to solve the technical problem that the pressing distance is limited when using a pressing plate, and it is impossible to press thinner materials as needed. Utility Model Content

[0005] The purpose of this invention is to provide a synchronous pressing assembly to solve the technical problem that the current pressing plate pressing method has a limited pressing distance and cannot press thinner materials as needed.

[0006] The technical solution of this utility model is implemented as follows:

[0007] The synchronous pressing assembly includes a lifting cylinder, a fixed plate, and a driving device. The lifting cylinder is mounted on the fixed plate, and its piston rod extends downward through the fixed plate. A lifting bracket is connected to the bottom of the piston rod, and a pressing bracket is connected to the bottom of the lifting bracket. Two transmission gear assemblies are arranged at both ends inside the pressing bracket, and two transmission chains are arranged between the two transmission gear assemblies. The two ends of the transmission chains are respectively connected to the two transmission gear assemblies for chain transmission. Pressure plates are evenly connected to the outside of the transmission chains. The driving device is used to drive the transmission gear assembly.

[0008] In a preferred embodiment, guide posts are provided at the four corners of the top of the lifting bracket, and guide sleeves that cooperate with the guide posts are provided at the bottom of the fixing plate. The guide posts and guide sleeves cooperate to limit and guide the vertical movement of the lifting bracket.

[0009] In a preferred embodiment, the pressing bracket extends through the interior of the lifting bracket, and the lifting bracket and the pressing bracket are connected by several horizontally placed connecting columns.

[0010] In a preferred embodiment, the transmission gear assembly includes a drive shaft, a first gear, and a transmission wheel. A first gear is provided at each of the left and right ends of the drive shaft, and a transmission wheel is provided on the outer side of one of the first gears. The drive device uses a transmission belt to drive the transmission wheel, and each first gear and its cooperating transmission chain form a chain drive.

[0011] In a preferred embodiment, a protective cover for protecting the transmission belt is provided on the outer side of the side wall of the pressure support.

[0012] The beneficial effects of this utility model are:

[0013] This solution is a synchronous pressing component specifically designed for pressing bagged food. Using this solution, the pressing plate can extend into the material hopper between the partitions and press synchronously with the conveyor belt (i.e., synchronous pressing). The pressing distance is not limited by the partitions. Compared to the current pressing technology where the pressing plate is blocked by the partitions, this solution can achieve a thinner pressing effect, has better applicability, and can be used with more packaging box sizes. It effectively solves the technical problem that the pressing distance of the current pressing plate is limited, making it impossible to press thinner materials as needed.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0025] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0026] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] See appendix Figures 1-5 The synchronous pressing assembly includes a lifting cylinder 5, a fixed plate 6, and a driving device 13. The lifting cylinder 5 is mounted on the fixed plate 6, and the piston rod of the lifting cylinder 5 passes downward through the fixed plate 6. The bottom of the piston rod is connected to a lifting bracket 7, and the bottom of the lifting bracket 7 is connected to a pressing bracket 9. Two transmission gear assemblies are provided at both ends inside the pressing bracket 9, and two transmission chains are provided between the two transmission gear assemblies. The two ends of the transmission chain 3 are respectively connected to the two transmission gear assemblies for chain transmission. Pressure plates 4 are evenly connected to the outside of the transmission chain 3. The driving device 13 is used to drive the transmission gear assembly.

[0028] The lifting support 7 is provided with guide posts 2 at the four corners of the top, and the bottom of the fixing plate 6 is provided with guide sleeves 1 that cooperate with the guide posts 2. The guide posts 2 and guide sleeves 1 cooperate to limit and guide the up and down movement of the lifting support 7.

[0029] The pressing bracket 9 passes through the interior of the lifting bracket 7, and the lifting bracket 7 and the pressing bracket 9 are connected by several horizontal connecting columns 8.

[0030] The transmission gear assembly includes a drive shaft 12, a first gear 11, and a transmission wheel 15. A first gear 11 is provided at each of the left and right ends of the drive shaft 12. A transmission wheel 15 is provided on the outer side of one of the first gears 11. The drive device 13 uses a transmission belt 14 to drive the transmission wheel 15. Each first gear 11 and the corresponding transmission chain 3 are in chain drive.

[0031] A protective cover 10 for protecting the transmission belt 14 is provided on the outer side of the side wall of the pressure bracket 9.

[0032] in, Figure 6 A schematic diagram of the prior art for pressing materials shows that the pressing plate 17 is obstructed by the partition 20, and the maximum pressing thickness is also greater than the height of the partition 20, so it cannot continue to press down. Figure 7 This is a schematic diagram of the pressing method. The pressing plate 4 can extend into the hopper between the partitions 20 to achieve thinner pressing.

[0033] In existing material pressing methods, if the material is lower than the hopper, it cannot be pressed down and will pile up together. However, the pressing plate of this solution can extend into the hopper and operates synchronously with the bottom, so it will not cause the material to shift to the side.

[0034] See appendix Figure 1 This solution can also include a handwheel and a cylinder. The handwheel can adjust the pressing depth according to the material thickness. The cylinder will pull up the entire device when the machine stops or when the material is stuck, making it easier to deal with the jamming problem. The spring is used to counteract the weight of the device to be pulled up, reducing the load on the cylinder. When the air circuit is disconnected, the spring force can pull up the entire pressing device, avoiding damage to the equipment when the air circuit fails.

[0035] The beneficial effects of this utility model are:

[0036] This solution is a synchronous pressing component specifically designed for pressing bagged food. Using this solution, the pressing plate can extend into the material hopper between the partitions and press synchronously with the conveyor belt (i.e., synchronous pressing). The pressing distance is not limited by the partitions. Compared to the current pressing technology where the pressing plate is blocked by the partitions, this solution can achieve a thinner pressing effect, has better applicability, and can be used with more packaging box sizes. It effectively solves the technical problem that the pressing distance of the current pressing plate is limited, making it impossible to press thinner materials as needed.
