Description

Technical Field

[0001] This utility model relates to the field of food packaging, and more specifically, to a food sealing and cutting machine. Background Technology

[0002] Food sealing and cutting machines are automated equipment widely used in the food packaging field. Their main function is to heat-seal and cut packaging materials (such as plastic films, composite films, etc.) to achieve sealed packaging of food.

[0003] Existing food sealing and cutting mechanisms, combined with high-speed pillow-pack machines, are designed to achieve efficient and automated production line processes. However, when pillow-pack machines are high-speed packaging machines, the heat sealing time is relatively short, which can result in insecure packaging seals. This makes food prone to leakage and moisture during transportation, leading to product spoilage or customer complaints.

[0004] If a product that has not been sealed needs to be resealed, the unused portion of the film before the sealing point must be removed to reduce the impact on subsequent packaging. This can easily lead to excessive film loss and increase packaging costs. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a food sealing and cutting machine that can preheat and seal the material to be sealed and cut, thereby ensuring the stability of the sealing and cutting process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a food sealing and cutting machine, comprising a machine base, a sealing and cutting mechanism, and a feeding mechanism, wherein a pre-sealing mechanism is provided on the machine base, and the pre-sealing mechanism and the sealing and cutting mechanism are arranged sequentially along the conveying direction of the feeding mechanism; a protective cover is provided on the machine base, and both the pre-sealing mechanism and the sealing and cutting mechanism are disposed within the protective cover;

[0007] An operating slot is provided on one side of the protective cover, and a door panel is hinged to the operating slot. An insulation layer is provided inside the protective cover.

[0010] The present invention is further configured such that: both the pre-sealing mechanism and the sealing and cutting mechanism include a mounting frame, an adjusting seat, an adjusting component, and a control component; the adjusting seat is slidably connected to the mounting frame; the adjusting component is disposed on the mounting frame and connected to the adjusting seat; and the control component is disposed on the adjusting seat.

[0011] The present invention is further configured such that: the pre-sealing mechanism further includes a heat sealing seat, and the adjusting member is connected to the heat sealing seat.

[0012] The present invention is further configured such that: the sealing and cutting mechanism further includes a heat sealing knife, and the adjusting member is connected to the heat sealing knife.

[0013] The present invention is further configured such that the adjusting component includes two sets of adjusting cylinders, which are symmetrically arranged at both ends of the adjusting seat.

[0014] The present invention is further configured such that: the adjusting component includes an adjusting handle and an adjusting screw; an adjusting hole is provided in the middle of the upper end of the mounting bracket; the adjusting screw is threadedly connected to the adjusting hole; one end of the adjusting screw is connected to the adjusting handle; and the other end is connected to the adjusting seat.

[0015] The present invention is further configured such that: the feeding mechanism includes a first feeding belt, a second feeding belt and a third feeding belt in sequence along its receiving direction, a first processing gap is left between the second feeding belt and the first feeding belt, and a second processing gap is left between the second feeding belt and the third feeding belt;

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] Reference Figures 1 to 4 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a food sealing and cutting machine, including a base 1, a sealing and cutting mechanism 2, and a feeding mechanism 3. A pre-sealing mechanism 4 is provided on the base 1. The pre-sealing mechanism 4 and the sealing and cutting mechanism 2 are arranged sequentially along the conveying direction of the feeding mechanism 3. A protective cover 5 is provided on the base 1. The pre-sealing mechanism 4 and the sealing and cutting mechanism 2 are both located inside the protective cover 5.

[0026] One side of the protective cover 5 is provided with an operating slot 51, and a door panel 52 is hinged to the operating slot 51. An insulation layer is provided inside the protective cover 5. The design of the door panel and the operating slot allows for easy opening to inspect and maintain the internal mechanism, and provides protection for the mechanism when the door panel is closed.

[0027] The design of this utility model has the following advantages: 1. The sealing area of ​​the material to be sealed is preheated first, which facilitates the subsequent heat sealing operation, ensures the sealing effect, and avoids the occurrence of weak sealing.

[0028] 2. A heat-gathering area is formed inside the protective cover 5. This heat-gathering area creates a temperature difference with the outside of the protective cover 5, resulting in a relatively higher internal temperature. This ensures that the temperature of the sealing and cutting blade drops slowly and heats up quickly in the later stages, thereby improving the stability of the sealing and cutting process.

[0029] It should be noted that the temperature of this heat-gathering area should not be too high to avoid affecting the normal operation of other devices.

[0030] The present invention is further configured such that: a ventilation hole is provided on one side of the protective cover 5, and a cooling fan 53 is installed at the ventilation hole.

[0031] The present invention is further configured such that: a temperature sensor is provided inside the protective cover 5, the temperature sensor is electrically connected to a controller, the controller is connected to the cooling fan 53, and the controller has a preset temperature threshold.

[0032] When there is only one set of cooling fans 53, different fan speeds can be set. When the temperature threshold is set to X, when the internal temperature of the protective cover 5 exceeds X, the temperature sensor sends an electrical signal. The controller sends a control signal based on the electrical signal to start the cooling fans 53.

[0033] If the internal temperature of the protective cover 5 still exceeds X within Y time after the cooling fan 53 starts, the delay clock module is triggered to send a control signal again, causing the cooling fan 53 to speed up.

[0034] When multiple cooling fans 53 are set, and the temperature threshold is set to Z, when the internal temperature of the protective cover 5 exceeds Z, the temperature sensor sends an electrical signal, and the controller sends a control signal based on the electrical signal to start one of the cooling fans 53.

[0035] If the internal temperature of the protective cover 5 still exceeds Z within W time after the cooling fan 53 starts, the delay clock module is triggered to send a control signal again, causing the second cooling fan 53 to start.

[0036] The control circuit between the controller, fan, and temperature sensor is existing technology and will not be described in detail here.

[0037] The present invention is further configured such that: both the pre-sealing mechanism 4 and the sealing and cutting mechanism 2 include a mounting frame 21, an adjusting seat 22, an adjusting component 23 and a control component 24. The adjusting seat 22 is slidably connected to the mounting frame 21, the adjusting component 23 is disposed on the mounting frame 21 and connected to the adjusting seat 22, and the control component 24 is disposed on the adjusting seat 22.

[0038] The present invention is further configured such that: the pre-sealing mechanism 4 also includes a heat sealing seat, and the adjusting member 23 is connected to the heat sealing seat.

[0039] This invention is further configured such that the sealing and cutting mechanism 2 also includes a heat sealing blade 25, and the adjusting member 23 is connected to the heat sealing blade 25. The difference between the heat sealing blade 25 and the heat sealing seat is that the heat sealing seat does not have a cutting function.

[0040] The present invention is further configured such that the adjusting member 23 includes two sets of adjusting cylinders, which are symmetrically arranged at both ends of the adjusting seat 22. The design of these adjusting cylinders allows them to extend simultaneously, thereby pushing the adjusting seat 22 up and down to complete the sealing and cutting operation.

[0041] The present invention is further configured such that: the adjusting component 23 includes an adjusting handle and an adjusting screw, an adjusting hole is provided in the middle of the upper end of the mounting bracket 21, the adjusting screw is threadedly connected to the adjusting hole, one end of the adjusting screw is connected to the adjusting handle, and the other end is connected to the adjusting seat 22.

[0042] The function of the adjusting element 23 is to adjust the distance between the adjusting seat 22 and the bottom up and down, so as to facilitate the passage of materials of different thicknesses.

[0043] By means of a lead screw structure, the adjusting seat 22 can slide and rise and fall as the adjusting screw rotates.

[0044] like Figure 3 As shown, the mounting bracket 21 also includes multiple guide columns to ensure the stability of the adjusting seat 22 during sliding and lifting and during the upper and lower sealing processes.

[0045] The present invention is further configured such that: the feeding mechanism 3 includes a first feeding belt 31, a second feeding belt 32 and a third feeding belt 33 in sequence along its receiving direction, a first processing gap 34 is left between the second feeding belt 32 and the first feeding belt 31, and a second processing gap 35 is left between the second feeding belt 32 and the third feeding belt 33.

[0046] The pre-sealing mechanism 4 is set to correspond to the first processing gap 34, and the sealing and cutting mechanism 2 is set to correspond to the second processing gap 35.

[0047] The design of this structure ensures that pre-sealing and sealing are unobstructed.

[0048] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
