Description

Technical Field

[0001] This application relates to the field of food production and packaging technology, and specifically discloses a pressing device for a film-coated packaging machine. Background Technology

[0002] In food production and processing, food is usually packaged for preservation. When packaging dried fruits and other similar products, the food is typically placed in batches on a packaging table, and then a film-wrapping machine is used to wrap and package it. Before wrapping, a pressing device consolidates and compresses the food items on the packaging table, and then the film-wrapping machine wraps the compressed items to reduce the volume of the packaged food, thus facilitating transportation.

[0003] However, existing pressing devices easily compress food materials. Therefore, the inventors have provided a pressing device for a film-coating and packaging machine to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional film-coating and packaging machines directly film and package materials without processing them, resulting in excessive gaps between materials and increasing the space required for material transportation and storage.

[0005] To achieve the above objectives, the basic solution of this utility model provides a pressing device for a film-coating and packaging machine, including a pressing base, a limiting frame located on the pressing base for placing the material to be packaged, an electric lifting rod symmetrically arranged between the pressing base and the limiting frame, and a controller. The pressing base is provided with a support frame located on one side of the limiting frame. The top of the support frame is provided with a mounting top plate located above the limiting frame. The bottom of the mounting top plate is provided with a pressing component for compressing the material in the limiting frame. The pressing component includes a guide frame located between the mounting top plate and the limiting frame, a first telescopic rod symmetrically arranged between the top of the guide frame and the mounting top plate, a pressing plate slidably connected to the inner wall of the guide frame, and a second telescopic rod arranged between the pressing plate and the inner top of the guide frame. The pressing plate can also slide along the inner wall of the limiting frame. The bottom end of the receiving frame is detachably connected to the top end of the limiting frame. The electric lifting rod, the first telescopic rod, and the second telescopic rod are all electrically connected to the controller.

[0006] The principle and effect of this basic scheme are as follows:

[0007] 1. Compared with the prior art, this utility model, by setting a limiting frame, a guide frame, and a pressing plate, facilitates the compression of dried fruit and fruit materials to be packaged. By setting a first telescopic rod, the height of the guide frame can be easily adjusted, thus facilitating the addition of materials into the limiting frame. By setting an electric lifting rod, the height of the limiting frame relative to the pressing base can be easily adjusted, thus facilitating the discharge operation from the bottom of the limiting frame after the material is compressed. This achieves the goal of compressing the material and reducing the overall volume of the material, making the dried fruit and fruit occupy less space after packaging. This facilitates the batch transportation and storage of packaged dried fruit and fruit, and solves the problem of traditional film-coating packaging machines directly coating and packaging materials without processing the materials, resulting in excessive gaps between materials and increasing the space required for transportation and storage.

[0008] Furthermore, the limiting frame includes a receiving frame that vertically overlaps with the guide frame and a limiting base plate located on the outer side of the bottom end of the receiving frame. An electric lifting rod is symmetrically positioned between the bottom side of the limiting base plate and the pressing base. The bottom end of the guide frame is detachably connected to the top end of the receiving frame. By setting the receiving frame and the limiting base plate, combined with the pressing base, the materials to be packaged (dried fruit and preserves) can be received, sealed, and limited.

[0009] Furthermore, the bottom of the pressing base has several evenly spaced support seats, two of which are located at the bottom of the electric lifting rod. The bottom end of the electric lifting rod is installed inside the bottom of the support seat, and the top end of the electric lifting rod passes through the pressing base and is connected to the limiting base plate. By setting the support seats, it is not only convenient to support the pressing base and the overall structure, but also convenient to install the electric lifting rod and to seal and adjust the material at the bottom of the receiving frame.

[0010] Furthermore, the outer top of the receiving frame is provided with an annular groove, and the outer bottom of the guide frame is provided with a connecting outer ring that engages with the annular groove. By providing the connecting outer ring and the annular groove, it is convenient to seal the top of the receiving frame, and at the same time, it is convenient for the pressure plate to press the material inside the receiving frame.

[0011] Furthermore, the top of the guide frame is evenly provided with several ventilation slots. By setting the ventilation slots, it is easier to vent air from the inside of the receiving frame and the guide frame, so that the pressing plate can better process the material.

[0016] A pressing device for a film-coating and packaging machine, implementing, for example Figure 1 As shown: It includes a pressing base 1, a limiting frame 2 located on the pressing base 1 for placing the material to be packaged, an electric lifting rod 3 symmetrically arranged between the pressing base 1 and the limiting frame 2, and a controller. The controller includes, but is not limited to, a PLC controller. The pressing base 1 is provided with a support frame 4 located behind the limiting frame 2. The top of the support frame 4 is provided with a mounting top plate 5 located above the limiting frame 2. The bottom of the mounting top plate 5 is provided with a pressing component for compressing the material in the limiting frame 2. The pressing component includes a guide frame 6 located between the mounting top plate 5 and the limiting frame 2, a first telescopic rod 7 symmetrically arranged between the top of the guide frame 6 and the mounting top plate 5, a pressing plate 8 slidably connected to the inner wall of the guide frame 6, and a second telescopic rod 9 located between the pressing plate 8 and the inner top of the guide frame 6. The pressing plate 8 can also slide along the inner wall of the limiting frame 2. The bottom end of the receiving frame 11 is detachably connected to the top end of the limiting frame 2. The electric lifting rod 3, the first telescopic rod 7 and the second telescopic rod 9 are all electrically connected to the controller.

[0017] Among them, such as Figure 1 As shown, the limiting frame 2 includes a receiving frame 11 that is vertically overlapped with the guide frame 6 and a limiting base plate 10 located on the outer side of the bottom end of the receiving frame 11. The electric lifting rod 3 is symmetrically arranged between the bottom side of the limiting base plate 10 and the pressing base 1. The bottom end of the guide frame 6 is detachably connected to the top end of the receiving frame 11.

[0018] Among them, such as Figure 1 As shown, the bottom of the pressing base 1 has six evenly spaced support seats 12, two of which are located at the bottom of two symmetrical electric lifting rods 3. The bottom end of the electric lifting rod 3 is installed inside the support seat 12, and the top end of the electric lifting rod 3 passes through the pressing base 1 and is connected to the limiting base plate 10.

[0019] Among them, such as Figure 1As shown, the top outer side of the receiving frame 11 is provided with an annular groove, and the bottom outer side of the guide frame 6 is provided with a connecting outer ring 13 that engages with the annular groove.

[0020] Among them, such as Figure 1 As shown, the top of the guide frame 6 is evenly provided with more than ten ventilation slots 14.

[0021] In the specific implementation of this utility model, before pressing the dried fruit or fruit, the controller first retracts the second telescopic rod 9 until its bottom does not exceed the bottom of the guide frame 6, and the first telescopic rod 7 retracts to its highest point, so that the guide frame 6 is above the limiting frame 2. Then, the controller lowers the electric lifting rod 3 until the limiting base plate 10 is in contact with the pressing base 1, so that the bottom of the limiting block is sealed. Subsequently, the dried fruit or fruit to be packaged is put into the receiving frame 11. Before the pressing operation, the amount of dried fruit or fruit in the receiving frame 11 does not exceed the capacity of the receiving frame 11. Next, the controller controls the first telescopic rod 7 to extend and drive the guide frame 6 to descend and engage with the connecting outer ring 13 and the annular groove, so that the bottom end of the guide frame 6 is connected to the top end of the receiving frame 11. Then, the material of dried fruit and fruit in the receiving frame 11 is pressed. During the pressing process, the controller controls the second telescopic rod 9 to extend and slide down along the inner wall of the receiving frame 11. The pressing plate 8 at the end of the second telescopic rod 9 applies pressure to the material of dried fruit and fruit below it. After the preset pressing time, the material of dried fruit and fruit is shaped, and the pressing process of dried fruit and fruit is completed. Finally, the pressed fruit and dried fruit materials need to be removed from the receiving frame 11. When discharging, the controller needs to retract the first telescopic rod 7 and the second telescopic rod 9 in sequence, so that the guide frame 6 and the pressing plate 8 are away from the receiving frame 11. Then, the controller drives the electric lifting rod 3 to rise, so that the limiting base plate 10 is lifted and separated from the pressing base 1, until the distance between the limiting base plate 10 and the pressing base 1 is greater than the pressing thickness of the fruit and dried fruit materials in the receiving frame 11. Finally, the fruit and dried fruit materials are directly taken out horizontally from the bottom of the receiving frame 11.

[0022] Compared with the prior art, this utility model, by setting a limiting frame 2, a guide frame 6, and a pressing plate 8, facilitates the compression of dried fruit and fruit materials to be packaged. By setting a first telescopic rod 7, the height of the guide frame 6 can be adjusted, thus facilitating the addition of materials to the limiting frame 2. By setting an electric lifting rod 3, the height of the limiting frame 2 relative to the pressing base 1 can be adjusted, thus facilitating the discharge operation from the bottom of the limiting frame 2 after the material is pressed. This achieves the compression of materials and reduces the overall volume of the materials, making the dried fruit and fruit occupy less space after packaging. This facilitates the batch transportation and storage of packaged dried fruit and fruit, and solves the problem of traditional film-coating packaging machines directly coating and packaging materials without processing them, resulting in excessive gaps between materials and increasing the space required for transportation and storage.
