Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, specifically a hot pressing mechanism for a packaging machine. Background Technology

[0002] Packaging machines are widely used in modern industrial production. Different packaging machines are used for different application scenarios. For example, blister packaging machines are a common type. They are used to heat and plasticize PVC, PE and other thermoplastic plastic rolls into various shapes of high-end packaging. The hot pressing mechanism is one of the important components of blister packaging machines.

[0003] When using the hot pressing mechanism of existing packaging machines, sheet plastic is usually placed in its working part and formed by pressing down. However, in actual operation, before pressing down, personnel often need to use clamping and fixing parts to fix the raw material. This adds an extra step to the entire processing, which not only increases the workload of the staff but also reduces the overall work efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a hot pressing mechanism for a packaging machine, which solves the problem that the existing hot pressing mechanism of the packaging machine needs to actively fix the raw material before pressing and forming, which affects the working efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hot pressing mechanism for a packaging machine, comprising a mounting plate, support columns installed at the four corners of the bottom of the mounting plate, and a bearing platform installed at the bottom end of the support columns, a hydraulic cylinder installed at the middle of the bottom of the mounting plate, and the output end of the hydraulic cylinder connected to the hot pressing plate body, and guide plates installed on both sides of the top of the hot pressing plate body, the guide plates penetrating the mounting plate;

[0006] Fixed chambers are installed on both sides of the bottom of the mounting plate. A movable block runs through the bottom of the fixed chamber. A fixed plate is installed on one side of the movable block, and a spring connects the fixed plate and the fixed chamber. A through hole is opened on one side of the movable block, and a U-shaped pressing fixed plate is installed inside the through hole.

[0007] An extrusion block is installed on the side of the guide plate away from the hot press plate body, and an extrusion mechanism for driving the movable block to move is provided on the fixed chamber.

[0008] An adjustment mechanism for fixing the U-shaped pressing plate is provided inside the through hole.

[0009] As a further embodiment of this utility model: the cross-sectional shape of the extrusion block is trapezoidal, and the extrusion block and the guide plate are manufactured as a single unit.

[0010] As a further embodiment of this utility model: the extrusion mechanism includes a movable plate, which runs through the fixed chamber on one side near the hot press plate body. An anti-detachment block is installed on the top of the movable plate. Mounting grooves are provided on both sides of the top of the movable plate. Fixed shafts are installed at both ends inside the mounting grooves, and sleeves are sleeved on the outside of the fixed shafts.

[0011] As a further embodiment of this utility model: the central axis of the sleeve coincides with the central axis of the fixed shaft, and the sleeve and the fixed shaft are rotatably connected.

[0012] As a further embodiment of this utility model: the adjusting mechanism includes a threaded rod, which is disposed at the top inside the through hole and passes through the movable block and the U-shaped pressing and fixing plate respectively, and a handle is installed at the bottom end of the threaded rod.

[0013] As a further embodiment of this utility model: the threaded rod and the movable block are rotatably connected, and the threaded rod and the U-shaped pressing and fixing plate are threadedly connected.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A hot pressing mechanism for a packaging machine includes a mounting plate 1. Support columns 2 are installed at the four corners of the bottom of the mounting plate 1, and a bearing platform 3 is installed at the bottom end of the support columns 2. A hydraulic cylinder 4 is installed at the middle of the bottom of the mounting plate 1, and the output end of the hydraulic cylinder 4 is connected to a hot pressing plate body 5. Guide plates 6 are installed on both sides of the top of the hot pressing plate body 5, and the guide plates 6 penetrate through the mounting plate 1. The guide plates 6 and the mounting plate 1 are slidably connected. In use, the raw material is placed at the designated position on the bearing platform 3, and the hydraulic cylinder 4 is controlled to drive the hot pressing plate body 5 to move downward to complete the hot pressing task. The hot pressing plate body 5 is the same as the existing similar hot pressing parts, and will not be described in detail here.

[0025] Fixed chambers 7 are installed on both sides of the bottom of the mounting plate 1. A movable block 8 runs through the bottom of the fixed chamber 7. A fixed plate 9 is installed on one side of the movable block 8, and a spring 10 connects the fixed plate 9 and the fixed chamber 7. A through hole 11 is opened on one side of the movable block 8, and a U-shaped pressing and fixing plate 12 is installed inside the through hole 11. The movable block 8 and the fixed chamber 7 are slidably connected, so that when the inclined part at the top of the movable block 8 is squeezed, the movable block 8 can move downward. Then, with the cooperation of the two sets of movable blocks 8, the two sets of U-shaped pressing and fixing plates 12 can press and fix the four corners of the raw material.

[0026] An extrusion block 13 is installed on the side of the guide plate 6 away from the hot press plate body 5. An extrusion mechanism for moving the movable block 8 is provided on the fixed chamber 7. The extrusion mechanism includes a movable plate 14, which extends through the fixed chamber 7 on the side closest to the hot press plate body 5. An anti-detachment block 15 is installed on the top of the movable plate 14. Mounting grooves 16 are provided on both sides of the top of the movable plate 14. Fixed shafts 17 are installed at both ends inside the mounting grooves 16, and sleeves 18 are fitted onto the outer sides of the fixed shafts 17. The extrusion block 13 has a trapezoidal cross-sectional shape and is integrally manufactured with the guide plate 6, allowing the hot press plate body 5 to move under... In the initial stage of descent, the inclined part of the extrusion block 13 can press the movable plate 14 away from the center. The movable plate 14 then presses the movable block 8 downward, so that the U-shaped pressing and fixing plate 12 can complete the automatic pressing task of the raw material. When the U-shaped pressing and fixing plate 12 completes the pressing task, the movable plate 14 is no longer pressing the inclined part of the extrusion block 13, but pressing the vertical surface of the extrusion block 13. This allows the movable block 8 and the U-shaped pressing and fixing plate 12 on it to be kept in the position of pressing the raw material. Then the hot press plate body 5 continues to move downward to complete the hot pressing task.

[0027] The central axis of the sleeve 18 coincides with the central axis of the fixed shaft 17, and the sleeve 18 and the fixed shaft 17 are rotatably connected. The sleeve 18 can replace the movable plate 14 to squeeze the extrusion block 13 and the movable block 8. During the extrusion process, the sleeve 18 can rotate, thereby reducing wear and ensuring service life.

[0028] An adjustment mechanism for fixing the U-shaped pressing and fixing plate 12 is provided inside the through hole 11. The adjustment mechanism includes a threaded rod 19, which is located at the top inside the through hole 11 and passes through both the movable block 8 and the U-shaped pressing and fixing plate 12. A handle 20 is installed at the bottom end of the threaded rod 19. The threaded rod 19 is rotatably connected to the movable block 8 and threadedly connected to the U-shaped pressing and fixing plate 12. The U-shaped pressing and fixing plate 12 and the through hole 11 form a relative sliding structure, which allows the operator to adjust the initial height of the U-shaped pressing and fixing plate 12 relative to the movable block 8 when dealing with raw materials of different batch thicknesses. This facilitates the initial stage of the subsequent descent of the hot press plate body 5 by pressing and fixing the raw materials through the U-shaped pressing and fixing plate 12.

[0029] The working principle of this utility model is as follows: The device is powered by an external power source. The raw material is placed at a designated position on the support platform 3. The hydraulic cylinder 4 is controlled to drive the hot press plate body 5 to move downward. As mentioned above, at this time, the inclined part of the extrusion block 13 can move the movable plate 14 away from the center. The movable plate 14 further extrudes the movable block 8 downward, so that the movable block 8 presses the four corners of the raw material through the U-shaped pressing and fixing plate 12 on it. Then the hydraulic cylinder 4 continues to drive the hot press plate body 5 to move downward to complete the hot pressing task. During this process, the vertical surface of the extrusion block 13 maintains the extrusion range of the movable plate 14, so that the U-shaped pressing and fixing plate 12 maintains the pressing of the raw material.

[0030] When hot pressing is required for raw materials of different thicknesses, the initial height of the U-shaped pressing fixing plate 12 relative to the movable block 8 can be adjusted by rotating the threaded rod 19, so that the movable block 8 can complete the hot pressing task of raw materials of different thicknesses in the initial stage of the subsequent descent of the hot pressing plate body 5.

[0031] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
