Description

Technical Field

[0001] This utility model relates to the technical field of egg carton forming equipment, and in particular to a floating hot press mold device for a packaging machine. Background Technology

[0002] Egg cartons are specialized containers used for packaging and transporting poultry eggs (such as chicken eggs, duck eggs, and quail eggs). They primarily protect eggs from damage and contamination and facilitate storage and sales. In the production process, waste paper is first vacuum-formed into wet blanks using a forming machine. These wet blanks are then hot-pressed. Existing egg carton forming machines use a sliding connection between the hot pre-pressing mold and the hot pressing upper mold and the machine frame, allowing for the switching of different upper and lower molds for hot pressing. However, the hot pressing upper mold lacks a floating buffer structure between itself and the machine frame, causing excessive pressure on the sliding rails and making them prone to damage. Therefore, a new hot pressing mold structure needs to be designed to address these issues. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a support base for a floating hot press mold device for a packaging machine, in which multiple hanging rods are connected to the upper hot press mold. The upper hot press mold can drive the hanging rods to float upward along the support base. Multiple buffers are provided between the support base and the upper hot press mold. In this way, during the hot pressing process, the upper hot press mold floats upward and is buffered by the buffers on the support base, thereby reducing the pressure on the frame and preventing the slide rails on the frame from being damaged due to excessive pressure.

[0004] A floating hot press mold device for a packaging machine includes a support base and a hot press upper mold installed on the top of the machine frame. Multiple hanging rods are slidably connected to the support base, and the multiple hanging rods are connected to the top surface of the hot press upper mold. Multiple buffers are provided between the support base and the hot press upper mold, and the hot press upper mold can drive the hanging rods to move up and down.

[0005] Preferably, the top of the frame is provided with two slide rails, and the frame is provided with multiple support protrusions between the two slide rails. There is a gap between the support protrusions and the hot pressing upper mold, and the hot pressing upper mold abuts against the support protrusions when it drives the hanging rod to move upward.

[0006] Preferably, a lifter is provided at the bottom of the frame, and a hot press lower mold is provided at the output end of the lifter.

[0007] Preferably, the top surface of the support base is provided with a plurality of sliders, and the plurality of sliders of the support base are slidably connected to the slide rail of the frame.

[0008] Preferably, the support base is provided with a plurality of receiving through holes, the receiving through holes and the top end of the lifting rod are both T-shaped structures, and the top ends of the plurality of lifting rods are slidably connected to the plurality of receiving through holes.

[0009] Preferably, the bottom surface of the support base is provided with a plurality of guide posts, the top surface of the hot pressing upper mold is provided with a plurality of sliding holes, and the top surface of the hot pressing upper mold is provided with a guide sleeve at the position of the sliding hole. The plurality of guide posts are slidably connected to the plurality of guide sleeves, and the guide posts extend into the sliding holes.

[0010] The beneficial effects of this utility model are: the floating hot press mold device of the packaging machine cooperates with the support base and the hot press upper mold, so that multiple hanging rods of the support base are connected to the hot press upper mold. The hot press upper mold can drive the hanging rods to float upward along the support base. In addition, multiple buffers are set between the support base and the hot press upper mold. In this way, during the hot pressing process, the hot press upper mold floats upward and is buffered by the buffers on the support base, thereby reducing the pressure on the frame and preventing the slide rails on the frame from being damaged due to excessive pressure.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0014] like Figures 1 to 4 As shown, a floating hot press mold device for a packaging machine includes a support base 2 and a hot press upper mold 3 installed on the top of the frame 1. Multiple hanging rods 4 are slidably connected to the support base 2, and the multiple hanging rods 4 are connected to the top surface of the hot press upper mold 3. Multiple buffers 5 are provided between the support base 2 and the hot press upper mold 3, and the hot press upper mold 3 can drive the hanging rods 4 to move up and down.

[0015] The working principle of the floating hot press mold device for packaging machines described in this utility model is achieved through the cooperation of the support base 2 and the hot press upper mold 3. Figures 1 to 4As shown, multiple lifting rods 4 of the support base 2 are connected to the hot pressing upper mold 3. The hot pressing upper mold 3 can drive the lifting rods 4 to float upward along the support base 2. Multiple buffers 5 are provided between the support base 2 and the hot pressing upper mold 3. The buffers 5 can be nitrogen buffers. The nitrogen buffers are equipped with controllable extension and retraction piston columns. This is an existing buffer structure and will not be described in detail. The multiple buffers 5 can be used to level the hot pressing upper mold 3 before hot pressing so that the hot pressing upper mold 3 and the hot pressing lower mold 7 remain horizontal during hot pressing. The multiple buffers 5 can also reduce the impact of the hot pressing upper mold 3 on the support base 2. In this way, during the hot pressing process, the hot pressing upper mold 3 floats upward and is buffered by the buffers 5 on the support base 2. Compared with the traditional hot pressing device of the packaging machine, this floating hot pressing mold device of the packaging machine can reduce the pressure on the frame 1 during hot pressing to prevent the slide rail on the frame 1 from being damaged due to excessive pressure.

[0016] Specifically, the top of the frame 1 is provided with two slide rails, and the frame 1 has multiple supporting protrusions 6 between the two slide rails. A gap is left between the supporting protrusions 6 and the upper hot-pressing mold 3, and the upper hot-pressing mold 3 abuts against the supporting protrusions 6 when it drives the lifting rod 4 to move upward. The bottom of the frame 1 is provided with a lifter, and the output end of the lifter is provided with a lower hot-pressing mold 7. Further, the top surface of the support base 2 is provided with multiple sliders 10, and all sliders 10 of the support base 2 are slidably connected to the slide rails of the frame 1. The support base 2 is provided with multiple receiving through holes 8, and both the receiving through holes 8 and the top ends of the lifting rods 4 are T-shaped structures. The top ends of the multiple lifting rods 4 are slidably connected to the multiple receiving through holes 8. Figures 1 to 4 As shown, the hot pressing upper mold 3 is slidably connected to the slide rail of the frame 1 via the slider 10. During the hot pressing process, there is a gap between the support protrusion 6 and the hot pressing upper mold 3, providing space for the hot pressing upper mold 3 to float. The lifting device drives the hot pressing lower mold 7 to move upward. The lifting device can adopt a conventional lifting structure with a servo motor and toggle linkage, so it will not be described in detail. The hot pressing lower mold 7 abuts against the hot pressing upper mold 3 and drives the hot pressing upper mold 3 to move upward. Then the hot pressing upper mold 3 drives the hanging rod 4 to move upward along the receiving through hole 8 of the support seat 2. The buffer 5 buffers the hot pressing upper mold 3, and the hot pressing upper mold 3 abuts against the support protrusion 6, so that the hot pressing upper mold 3 can float upward during the hot pressing process, thereby reducing the pressure on the support seat 2 and the slide rail, so as to prevent the slide rail on the frame 1 from being damaged due to excessive pressure.

[0017] Furthermore, the bottom surface of the support base 2 is provided with a plurality of guide posts 9, and the top surface of the hot pressing upper mold 3 is provided with a plurality of sliding holes 10. A guide sleeve 11 is provided on the top surface of the hot pressing upper mold 3 at the position of the sliding hole 10. The plurality of guide posts 9 are slidably connected to the plurality of guide sleeves 11, and the guide posts 9 extend into the sliding holes 10. Figures 1 to 4As shown, when the hot pressing upper mold 3 floats upward, the guide post 9 can extend downward into the sliding hole 10 along the guide sleeve 11, which has the function of guiding and limiting. After the hot pressing process is completed, the lifting device drives the hot pressing lower mold 7 to reset downward. The hot pressing upper mold 3 moves downward under its own gravity and drives the lifting rod 4 and the guide sleeve 11 to reset.
