Description

Technical Field

[0001] This utility model relates to the field of packaging machines, and in particular to a quick-assembly and disassembly heating and sealing mechanism. Background Technology

[0002] After the contents are placed in the packaging, they undergo a series of adjustments, including sorting, and are then sealed by the sealing mechanism. Existing sealing machines have limited operating space and long replacement times when changing heating wires, which affects production efficiency. In addition, the heating wires expand after heating, and in existing devices, the increased length of the heating wires after expansion causes them to sag or shift, affecting the final sealing effect. Utility Model Content

[0003] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the objective of this invention is to provide a device that allows for the rapid replacement of the heating element.

[0004] To achieve the above objectives, embodiments of this utility model provide a quick-assembly and disassembly heating sealing mechanism, comprising:

[0005] A fixing element is fixed to an external device, and a heating assembly is provided on top. A temporary locking mechanism is formed between the fixing element and the heating assembly by a locking element.

[0006] The heating assembly consists of a support base, a pad, a heating wire, and a tensioning element. The support base is fixed to a fixing element. A pad is provided on the top of the support base. The heating wire is laid on the pad and its two ends are respectively fixed to tensioning elements located at both ends of the pad. The tensioning elements are slidably connected to the support base and tend to keep away from each other.

[0007] The locking element consists of a handle, a lock body, and a hook body. The lock body is located on the fixed element, and the hook body is located on the support base on the same side as the lock body. The handle controls the opening and closing of the lock body and the hook body.

[0008] The quick-assembly and quick-disassembly heating and sealing mechanism according to the present utility model uses a modular design. When replacing the heating wire, only the spare heating component needs to be replaced to start production, without affecting the equipment's start-up efficiency. The tensioning element limits the left and right movement of the heating wire to avoid the problem of thermal expansion and contraction during heating, and to prevent the heating wire from shifting during operation.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] Figures 1 to 5 A quick-assembly and disassembly heating sealing mechanism according to an embodiment of the present utility model includes:

[0028] A fixing element is fixed to an external device, and a heating component 2 is provided on the top. A temporary locking mechanism is formed between the fixing element 1 and the heating component 2 by a locking element 3. In some embodiments, the fixing element 1 is provided with a mounting groove 11 for placing the heating component 2 along the length direction. The mounting groove 11 restricts the movement tendency of the fixing element 1 along the length direction to better install and maintain stability during use.

[0029] Heating assembly 2 consists of support base 21, pad 22, heating wire 23 and tensioning element 24. Support base 21 is fixed to fixing element 1. Pad 22 is provided on the top of support base 21. Specifically, the top of support base is provided with fixing groove for pad 22 to be placed. Heating wire 23 and pad 22 are inserted into fixing groove, so that heating wire 23 and pad 22 are constrained in the vertical length direction. In the existing structure, heating wire is prone to expansion after heating, and is prone to displacement in the width direction, resulting in "S" shaped twist, which makes the shape of the package after sealing unstable. The design of this utility model can largely solve this problem.

[0030] The heating wire 23 is laid on the pad 22. In some embodiments, the pad 22 is made of an insulating elastic material such as perfluoroelastomer rubber. The pad 22 can be reused after the heating wire 23 is replaced, and the pad 22 itself can also be replaced.

[0031] The heating wire 23 is fixed at both ends to tensioning elements 24 located at both ends of the pad 22. The tensioning elements 24 are slidably connected to the support base 21 and tend to move away from each other. Specifically, the tensioning elements 24 and the support base are connected by a slider and a groove to form a slidable connection. A spring is provided between the tensioning elements 24 and the support base. The spring maintains the tendency of relative movement between the tensioning elements 24 and the support base. That is, through real-time tension, the heating wire 23 is always kept in a relatively straight state.

[0032] Furthermore, the top of the tensioning element 24 is provided with an assembly groove for fixing the heating wire 23. The heating wire 23 is fixed in the assembly groove. The assembly groove can also be provided with a pad 22 to play a role in heat insulation and insulation. After the heating wire 23 extends out of the tensioning element 24, it is connected to the external power supply to control the temperature of the heating time.

[0033] The locking element 3 consists of a handle 31, a lock body 32, and a hook body 33. The lock body 32 is located on the fixing element 1, and the hook body 33 is located on the support base 21, on the same side as the lock body 32. The handle 31 controls the opening and closing of the lock body 32 and the hook body 33. The specific structure of the locking element 3 can be referred to the structure of existing metal buckles, and will not be described in detail here.

[0034] This invention solves the problem of limited operating space and long replacement time when changing heating wire 23 in packaging machines, which affects production efficiency. Due to its modular design, replacing heating wire 23 only requires replacing the spare heating assembly 2, and the machine can then start production. After the machine is started, the removed heating assembly 2 can be used to replace heating wire 23 or pad 22, and the replacement time does not affect the machine's start-up efficiency. Simultaneously, the pad 22 in the heating assembly 2 limits the left and right movement of heating wire 23, and to prevent thermal expansion and contraction of heating wire 23 during heating, tensioning element 24 tightens heating wire 23 from both ends, solving the problem of heating wire 23 twisting, deforming, and shifting.
