Description

Technical Field

[0001] This utility model relates to the field of food packaging equipment technology, specifically to an exhaust device. Background Technology

[0002] Currently, the condiment industry, fast food industry, and central kitchen catering industry need to package, transport, and store a large number of oil and sauce packets, soups, and pre-made semi-finished products. In order to keep them fresh and prevent them from contacting air, and to freeze them into beautiful shapes without flower bags or air gaps, it is necessary to fully vent the air and reduce the risk of material oxidation. At present, the traditional plate-type fixed roller cannot adjust the venting position online to fully vent the finished products. Utility Model Content

[0003] In order to solve the technical problems existing in the prior art, this application provides an exhaust device.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: an exhaust device, comprising: a bracket for connecting to packaging equipment; an exhaust mechanism, the exhaust mechanism comprising exhaust rollers symmetrically arranged on the bracket and a driving element for driving the exhaust rollers, the exhaust rollers being slidably arranged on the bracket, and an exhaust gap being formed between the two exhaust rollers; an adjustment mechanism disposed between the exhaust rollers and the driving element, the adjustment mechanism comprising a horizontal plate, a lifting seat and a driving element, the horizontal plate being slidably arranged on the bracket, the lifting seat being disposed on the horizontal plate, the exhaust rollers being disposed on the lifting seat, and the driving element being disposed on the lifting seat, and the driving element being used to drive the exhaust rollers to move on the lifting seat.

[0005] In some embodiments of this utility model, the exhaust roller includes a base shaft, a bearing, and a rotating roller. The bearing is sleeved on the base shaft, the rotating roller is sleeved on the bearing, and the base shaft is connected to the lifting seat.

[0006] In some embodiments of this utility model, the lifting seat is provided with a keyway for supporting the sliding of the base shaft, and the driving member is used to drive the base shaft to slide back and forth in the opening direction of the keyway.

[0007] In some embodiments of this utility model, the driving component includes a screw, a support, and a grip handle. The support is disposed on the lifting seat, and the grip handle is rotatably disposed on the support. The screw passes through the grip handle and the support in sequence, and the screw is threadedly connected to the grip handle.

[0008] In some embodiments of this utility model, the bracket includes a sliding rod and a sleeve, with the sleeve slidably disposed on the sliding rod and the horizontal plate mounted on the sleeve.

[0009] Beneficial effects: 1. By sliding the horizontal plate on the support and precisely driving the exhaust roller on the lifting seat, the exhaust roller can be flexibly adjusted in multiple dimensions, both horizontally and vertically. This multi-dimensional adjustment capability allows the device to adapt to various packaging items of different sizes, shapes, and thicknesses, greatly improving its versatility and applicability. It reduces the hassle of replacing or adjusting equipment due to differences in packaged items, thereby lowering production costs and equipment downtime.

[0010] 2. Because the position of the exhaust rollers can be precisely adjusted according to the actual situation of the packaged goods, it can be ensured that the exhaust gap between the two exhaust rollers is always in an optimal state. A suitable exhaust gap ensures that during the exhaust process, air inside the packaging is fully expelled without excessive compression of the packaged goods. This effectively avoids problems such as packaging damage and product deformation caused by improper exhaust, thus improving packaging quality and product market competitiveness.

[0020] Please refer to Figures 1-4This embodiment provides an exhaust device. During the operation of the packaging equipment, the exhaust device is first reliably connected to the packaging equipment via a bracket 1. Based on the specifications of the packaged items and packaging requirements, the position of the exhaust roller 2 is adjusted using an adjusting mechanism. The horizontal plate 4 slides horizontally on the bracket 1 to initially determine the approximate horizontal position of the exhaust roller 2; the lifting seat 5 moves vertically up and down on the horizontal plate 4 to adjust the height of the exhaust roller 2; the driving component 6 drives the exhaust roller 2 to make fine adjustments on the lifting seat 5, so that the exhaust gap between the two exhaust rollers 2 reaches the optimal state. When the packaged items pass through the exhaust gap, the driving component 3 drives the exhaust roller 2 to move towards the items to be packaged, applying pressure to the packaging bag of the packaged items to expel excess air from the packaging, completing the exhaust operation.

[0021] Specifically, the exhaust device includes a bracket 1 for connecting to the packaging equipment; the bracket 1 is used to install the entire exhaust device in a reserved position on the packaging equipment, ensuring that the exhaust device can be accurately integrated into the packaging equipment, and will not be displaced or shaken due to equipment vibration or movement during packaging operations, providing a reliable guarantee for the stable operation of exhaust, and avoiding problems such as poor exhaust effect or equipment damage caused by device instability.

[0022] The venting device also includes a venting mechanism, which includes venting rollers 2 symmetrically arranged on the support 1 and a driving element 3 for driving the venting rollers 2. The venting rollers 2 are slidably arranged on the support 1, and a venting gap is formed between the two venting rollers 2. When the packaged items pass through the gap, the venting rollers 2 move centrally under the drive of the driving element 3. Since it is for venting the sauce, the sauce opening is compressed, and excess air is discharged. The amount of air remaining inside the packaging bag is small, which reduces the packaging volume and prevents the product from oxidizing, deteriorating, or being damaged due to the presence of air during transportation and storage, thus extending the product's shelf life and improving the compactness and aesthetics of the packaging.

[0023] Furthermore, the aforementioned driving element 3 is connected to the exhaust roller 2, driving the exhaust roller 2 to move at a set speed and direction, thereby achieving continuous exhaust operation. This provides stable and controllable power to the exhaust roller 2, ensuring the continuity and uniformity of the exhaust process. The parameters of the driving element 3 can be adjusted according to different packaging materials and product characteristics to obtain the optimal exhaust effect, improving production efficiency and product quality. The exhaust roller 2 is mounted on the support 1 via sliding components such as slide rails and sliders, allowing the exhaust roller 2 to move horizontally on the support 1, thereby adjusting the exhaust gap between the two exhaust rollers 2. The exhaust gap can be flexibly adjusted according to parameters such as the thickness and size of the packaged items, adapting to the exhaust requirements of different product specifications, improving the versatility and adaptability of the device, and avoiding problems such as insufficient exhaust or excessive product compression due to unsuitable exhaust gaps.

[0024] An adjustment mechanism is installed between the exhaust roller 2 and the drive element 3. The adjustment mechanism includes a horizontal plate 4, a lifting seat 5, and a drive component 6. The horizontal plate 4 is slidably mounted on the bracket 1. The lifting seat 5 is mounted on the horizontal plate 4. The exhaust roller 2 is mounted on the lifting seat 5. The drive component 6 is mounted on the lifting seat 5 and is used to drive the exhaust roller 2 to move on the lifting seat 5. The lifting seat 5 is mounted on the horizontal plate 4 and achieves vertical lifting movement through a lifting mechanism such as a screw nut and a hydraulic cylinder. The exhaust roller 2 is mounted on the lifting seat 5, and its height changes as the lifting seat 5 moves. The vertical position of the exhaust roller 2 can be precisely adjusted, allowing the exhaust gap to be accurately matched to the height of the packaged items, ensuring ideal exhaust effects in packaging operations at different heights, while avoiding damage to the product due to unsuitable height. The drive component 6 is mounted on the lifting seat 5 and connected to the exhaust roller 2. It can drive the exhaust roller 2 to move vertically on the lifting seat 5, further fine-tuning the relative position between the two exhaust rollers 2. The position of the exhaust roller 2 can be precisely adjusted. When dealing with some packaging products that require high exhaust accuracy, the fine-tuning function of the drive component 6 can make the exhaust gap reach the optimal state, thereby improving the exhaust quality and the consistency of product packaging.

[0025] Please refer to Figures 1-4 In some embodiments of this example, the exhaust roller 2 includes a base shaft 201, a bearing 202 and a rotating roller 203. The bearing 202 is sleeved on the base shaft 201, and the rotating roller 203 is sleeved on the bearing 202. The base shaft 201 is connected to the lifting seat 5.

[0026] In this embodiment, the base shaft 201 is connected to the lifting seat 5. The base shaft 201 is driven to rise and fall by the lifting component, thereby driving the entire exhaust roller 2 to rise and fall. When packaging bags of different specifications, it can be adapted to increase its application range. The bearing 202 is sleeved on the base shaft 201, with its inner ring tightly fitted to the base shaft 201 and its outer ring connected to the rotating roller 203.

[0027] During the venting process, when the drive element 3 drives the rotating roller 203 to rotate, the bearing 202, through the rolling of its internal rolling elements, converts the sliding friction between the rotating roller 203 and the base shaft 201 into rolling friction, greatly reducing frictional resistance. The rotating roller 203 is mounted on the bearing 202 and rotates around the base shaft 201 under the drive of the drive element 3. When the packaged item passes through the venting gap between the two venting rollers 2, the two opposing venting rollers 2 converge to clamp the packaging bag, then pull it upwards to expel excess air before sealing and cutting.

[0028] Please refer to Figures 1-4 In some embodiments of this example, the lifting seat 5 is provided with a keyway 7 for supporting the sliding of the base shaft 201, and the driving member 6 is used to drive the base shaft 201 to slide back and forth in the opening direction of the keyway 7.

[0029] In this embodiment, the lifting seat 5 is used to install and adjust the height of the base shaft 201, which can be adjusted according to different specifications of the packaging bag. The base shaft 201 and the driving component 6 are connected by screws (not shown in the figure), with the screws passing through the driving component 6, the keyway 7, and the base shaft 201 in sequence.

[0030] Please refer to Figures 1-4 In some embodiments of this example, the drive component 6 includes a screw 601, a support 602, and a grip handle 603. The support 602 is disposed on the lifting seat 5, and the grip handle 603 is rotatably disposed on the support 602. The screw 601 passes through the grip handle 603 and the support 602 in sequence, and the screw is threadedly connected to the grip handle 603.

[0031] In this embodiment, the grip handle 603 is used for hand gripping. When the grip handle 603 is rotated, the middle part of the grip handle 603 is connected to the screw 601 through a threaded engagement, and the end of the screw 601 is connected to the base shaft 201 through a screw. Thus, when the grip handle 603 is rotated, the end of the screw 601 moves along the opening direction of the keyway 7.

[0032] Please refer to Figures 1-4 In some embodiments of this example, the bracket 1 includes a slide rod 101 and a sleeve 102, the sleeve 102 is slidably disposed on the slide rod 101, and the horizontal plate 4 is mounted on the sleeve 102.

[0033] In the packaging equipment, the appropriate positions of the transverse plate 4 and the exhaust roller 2 on it are first determined according to the specifications of the packaged items and the packaging process requirements. Then, an external force is applied to the sleeve 102 by the drive device, causing the sleeve 102 to slide along the slide bar 101. Since the transverse plate 4 is mounted on the sleeve 102, the sliding of the sleeve 102 drives the transverse plate 4 to move together, thereby realizing the position adjustment of the transverse plate 4 and the exhaust roller 2. When the transverse plate 4 reaches the predetermined position, the drive device stops working, and the sleeve 102 remains stationary after reaching the preset position, allowing for subsequent packaging operations.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
