Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, specifically relating to a bag-sealing device for fruit and vegetable beverages. Background Technology

[0002] In the food processing industry, the process typically involves several steps: sorting, processing, bagging, sealing, sterilization, and boxing. The sealing step is arguably the most crucial in the entire food processing process, as the quality of the seal is a key factor affecting food preservation. If the sealing quality meets the standards, the food can be preserved as expected. However, if the sealing quality is substandard, the food is prone to poor preservation and spoilage earlier than expected. Therefore, sealing machines, as sealing tools, also need to be carefully selected.

[0003] For example, the utility model patent with patent authorization announcement number CN209097137U provides a bagged beverage sealing machine, including a machine housing, a fixed mold assembly, a moving mold assembly, and a conveying assembly. The fixed mold assembly includes a first cylinder, a first piston rod, a heating seat, a heater, a heat-conducting connecting block, and a sealing mold. The moving mold assembly includes a second cylinder, a second piston rod, an electric push rod, a heating connecting block, and a sealing mold.

[0004] Based on the search of patent grant announcement numbers and considering their shortcomings, the following was found:

[0005] Existing bagged beverage sealing machines require filled beverage bags to be placed in a material trough, which then moves the bags to a designated position for sealing. Therefore, existing bagged beverage sealing machines can only seal bags that are placed stably. Currently, rectangular bags that cannot be placed stably are still sealed manually, which slows down the sealing speed and efficiency of bagged beverages. Utility Model Content

[0006] To address the issue that existing bagged beverage sealing machines require filled beverage bags to be placed in a material trough, which then moves the bags to a designated position for sealing, these machines can only seal bags that are placed stably. Currently, rectangular bags that cannot be placed stably are still sealed manually, which slows down the sealing speed and reduces efficiency. This invention provides a bag-sealing device for fruit and vegetable beverages.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A fruit and vegetable beverage bag sealing device includes a body, a sealing component, and a transport component. The sealing component is disposed on the body and is used to seal the packaging bag. The transport component includes a transport belt and several transport units. The transport belt is rotatably disposed at the bottom of the body and is located directly below the sealing component.

[0009] Several transport units are equally spaced on the transport belt along the rotation direction of the transport belt. Each transport unit includes a left placement block, a right placement block, and a bottom placement block. The left and right placement blocks are respectively disposed opposite each other on both sides of the transport belt. The bottom placement block is disposed on the transport belt and is located between the left and right placement blocks. The left, right, and bottom placement blocks together form a placement slot, which is used to engage with the rigid ends of the left, right, and bottom of the packaging bag.

[0010] As a preferred embodiment of this utility model, the transport unit further includes a transport motor, a horizontal plate, and two circular rollers. The horizontal plate is horizontally mounted on the machine body and is located directly below the sealing assembly. The two circular rollers are rotatably mounted on the machine body and are located at the lower ends of the horizontal plate. The transport belt is rotatably fitted onto the outer diameter path formed by the horizontal plate and the two circular rollers. The transport motor is mounted on the machine body, and the output end of the transport motor is coaxially connected to either of the circular rollers.

[0011] In a preferred embodiment of this invention, the height of the packaging bag is higher than the height of the placement slot, and the distance between the rigid ends of the two ends of the packaging bag is equal to the distance between the placement slot of the left placement block and the placement slot of the right placement block.

[0012] As a preferred embodiment of this utility model, the transport unit further includes three assisting blocks, each of which has an assisting slot. The three assisting blocks correspond to and match the left placement block, the right placement block, and the bottom placement block, respectively. Each assisting block is placed on the corresponding placement block. The assisting slot is connected to the placement slot. The width of the assisting slot is greater than the width of the packaging bag containing the beverage.

[0013] As a preferred embodiment of this utility model, the width of the assisting slot gradually decreases along the direction from the assisting block to the corresponding placement block, and the minimum width of the assisting slot is equal to the width of the placement slot.

[0014] As a preferred embodiment of this utility model, the sealing assembly includes a lifting cylinder, a lifting plate, a bonding plate, a pressing block, a heating device, and a telescopic cylinder. The lifting cylinder is located on the top of the machine body. The lifting plate is connected to the output end of the lifting cylinder. The lifting plate is slidably mounted on the top of the machine body. The bonding plate is connected to the bottom of one end of the lifting plate. The telescopic cylinder is located at the other end of the bottom of the lifting plate, relative to the bonding plate. The heating device is connected to the output end of the telescopic cylinder. The pressing block is mounted on the heating device and can lock or release its bonding relationship with the bonding plate.

[0015] As a preferred technical solution of this utility model, the sealing assembly further includes a positioning cylinder and a positioning block. The positioning cylinder is disposed on the machine body and located on one side of the conveyor belt. The positioning block is connected to the output end of the positioning cylinder and can lock or release its mutual contact relationship with the corresponding transport unit.

[0016] As a preferred embodiment of this utility model, the sealing assembly further includes a detection rod, a detection spring, and a detection module. The detection module is disposed on the end of the positioning block away from the bonding plate. The detection rod is slidably disposed on the pressing block. The detection rod is located between the bonding plate and the detection module, and the end of the detection rod near the bonding plate extends out of the positioning block. The sliding direction of the detection rod is the same as the extension direction of the output end of the telescopic cylinder. The two ends of the detection spring are respectively connected to the detection rod and the pressing block. The detection rod can lock or release its pressing engagement with the detection module.

[0017] In a preferred embodiment of this utility model, the detection module is communicatively connected to the positioning cylinder. The detection module is equipped with a delay command. After the detection rod presses the detection module, the detection module starts the delay command. After the delay command ends, the positioning cylinder is controlled to retract.

[0018] As a preferred technical solution of this utility model, it also includes a sterilization lamp, which is disposed on the machine body and located at the top of the conveyor belt to sterilize the opening of the packaging bag to be sealed.

[0019] The beneficial effects of this utility model are as follows:

[0020] This solution incorporates placement slots. The rigid ends of the packaging bag—left, right, and bottom—correspond to the placement slots formed by the left, right, and bottom placement blocks, respectively. This allows the rigid ends of the packaging bag to be secured within the slots, enabling the bag to stand upright on the transport unit. This ensures that the subsequent sealing components can smoothly seal the upright bag. This solution addresses the problem of existing bagged beverage sealing machines, which require filled beverage bags to be placed in a material trough, which then moves the bag to a designated position for sealing. Consequently, existing bagged beverage sealing machines can only seal bags that are placed stably. Currently, rectangular bags that cannot be placed stably are still sealed manually, which slows down the sealing speed and reduces efficiency. Attached Figure Description

Detailed Implementation

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] Please see Figures 1-3This embodiment provides a bag-sealing device for fruit and vegetable beverages, including a body 1, a sealing component 2, and a transport component 3. The sealing component 2 is disposed on the body 1 and is used to seal the packaging bag. The transport component 3 includes a transport belt 306 and several transport units. The transport belt 306 is rotatably disposed at the bottom of the body 1 and is located directly below the sealing component 2. Several transport units are equally spaced on the transport belt 306 along the rotation direction of the transport belt 306. Each transport unit includes a left placement block 301, a right placement block 302, and a bottom placement block 303. The left placement block 301 and the right placement block 302 are respectively disposed opposite to each other on both sides of the transport belt 306. The bottom placement block 303 is set on the conveyor belt 306, and is located between the left placement block 301 and the right placement block 302. The left placement block 301, the right placement block 302 and the bottom placement block 303 together form a placement slot 3082, which is used to engage with the rigid ends of the left, right and bottom of the packaging bag. It is worth noting that the packaging bag in this solution has an inner cavity in the middle, and the inner cavity is used to fill fruit and vegetable beverages. The left, right and bottom of the packaging bag are all provided with a rectangular structure with a rigid end. The rigid end refers to a flexible structure with a certain toughness and no inner cavity. In this solution, the rigid end and the packaging bag are designed as an integral structure. By providing placement slots 3082, the rigid ends of the left, right, and bottom of the packaging bag cooperate with the placement slots 3082 formed by the left placement block 301, right placement block 302, and bottom placement block 303, respectively. This allows the rigid ends of the packaging bag to be locked within the placement slots 3082, enabling the packaging bag to stand upright on the transport unit. This ensures that the subsequent sealing component 2 can smoothly seal the upright packaging bag. This solves the problem that existing bagged beverage sealing machines require the filled beverage packaging bags to be placed in a material trough, which then moves the packaging bag to a designated position for sealing. Therefore, existing bagged beverage sealing machines can only seal packaging bags that are placed stably. Currently, rectangular packaging bags that cannot be placed stably are still sealed manually, which slows down the sealing speed and efficiency of bagged beverages.

[0029] Specifically, the transportation unit of this solution also includes a transport motor 304, a horizontal plate 305, and two circular rollers 307. The horizontal plate 305 is horizontally mounted on the machine body 1 and is located directly below the sealing assembly 2. The two circular rollers 307 are rotatably mounted on the machine body 1 and are located at the lower ends of the horizontal plate 305. The transport belt 306 is rotatably fitted onto the outer diameter path formed by the horizontal plate 305 and the two circular rollers 307. The transport motor 304 is mounted on the machine body 1, and the output end of the transport motor 304 is connected to any... A circular roller 307 is coaxially connected; a transport motor 304 is provided, and the output end of the transport motor 304 rotates, thereby driving the circular roller 307 to rotate. Since the transport belt 306 is fitted on the outer diameter path formed by the horizontal plate 305 and the two circular rollers 307, the transport belt 306 will rotate along with the rotation of the circular roller 307, so that the transport unit set on the transport belt 306 and the packaging bag set on the transport unit move together to the bottom of the sealing assembly 2, so as to facilitate the subsequent sealing assembly 2 to seal the bag opening.

[0030] It is worth noting that, in order to facilitate the sealing component 2 in sealing the opening of the packaging bag, the height of the packaging bag in this design is higher than the height of the placement slot 3082. At the same time, the distance between the rigid ends of the packaging bag is equal to the distance between the placement slot 3082 of the left placement block 301 and the placement slot 3082 of the right placement block 302. This setting ensures that when the rigid end of the packaging bag is engaged in the placement slot 3082, the space of the placement slot 3082 will not interfere with the structure of the packaging bag. This ensures that when the rigid end of the packaging bag and the placement slot 3082 cooperate with each other, the fruit and vegetable beverages inside the packaging bag will not spill out.

[0031] Furthermore, it should be noted that the rigid end of the packaging bag in this solution is also a flexible structure, only slightly more flexible than the packaging bag itself. However, during the actual sealing process, the packaging bag will contain fruits, vegetables, and beverages, which will result in a large overall inertia of the packaging bag. If the packaging bag tends to tilt during the movement of the transport unit, the rigid end of the packaging bag will also deform, thereby releasing its engagement with the placement slot 3082. This will prevent the packaging bag from maintaining an upright position, thus affecting the subsequent sealing process of the sealing component 2. Based on this, the transportation unit of this solution also includes three assisting blocks 308. Each assisting block 308 has an assisting slot 3081. The three assisting blocks 308 correspond to and match the left placement block 301, the right placement block 302, and the bottom placement block 303, respectively. Any assisting block 308 is set on the corresponding placement block. The assisting slot 3081 and the placement slot 3082 are interconnected. The width of the assisting slot 3081 is greater than the width of the packaging bag containing the beverage. By setting the assisting slot 3081, the function of the assisting slot 3081 is to prevent the packaging bag from tilting too much, thereby affecting the engagement relationship between the rigid end of the packaging bag and the placement slot 3082, and further ensuring that the packaging bag can stand upright on the transportation unit. It is worth noting that, since the packaging bag and the rigid end of this solution are designed as a single piece, the closer the packaging bag is to the rigid end within a certain distance, the smaller the width of the packaging bag after it is filled with beverage. Based on this, in order to adapt to the characteristics of the packaging bag, the width of the assisting slot 3081 gradually decreases along the direction from the assisting block 308 to the corresponding placement block. The minimum width of the assisting slot 3081 is equal to the width of the placement slot 3082.

[0032] Furthermore, the sealing component 2 of this solution includes a lifting cylinder 201, a lifting plate 202, a bonding plate 203, a pressing block 204, a heating device 205, and a telescopic cylinder 206. The lifting cylinder 201 is located on the top of the machine body 1. The lifting plate 202 is connected to the output end of the lifting cylinder 201. The lifting plate 202 is slidably mounted on the top of the machine body 1 and is horizontally positioned. The bonding plate 203 is connected to the bottom of one end of the lifting plate 202. The telescopic cylinder 206 is located at the other end of the bottom of the lifting plate 202, relative to the bonding plate 203. The heating device 205 is connected to the output end of the telescopic cylinder 206. The pressing block 204 is mounted on the heating device 205 and can lock or release its contact with the bonding plate. The bonding relationship between the plywood 203 is as follows: A heating device 205 is provided, which raises its own temperature and transfers the temperature to the pressing block 204, causing the pressing block 204 to heat up. As the transport unit moves the packaging bag to the designated position, the output end of the lifting cylinder 201 controls the height of the lifting plate 202 to decrease. Then, the bonding plate 203 and the pressing block 204 are located at the two ends of the bag opening, respectively. Then, the telescopic cylinder 206 works, and its output end extends, causing the pressing block 204 to bond towards the bonding plate 203. Thus, the pressing block 204 and the bonding plate 203 jointly press the bag opening, thereby sealing the bag opening.

[0033] As can be seen from the above embodiments, in order to ensure that the opening of the packaging bag moves precisely between the bonding plate 203 and the pressing block 204, the sealing assembly 2 of this solution also includes a positioning cylinder 207 and a positioning block 208. The positioning cylinder 207 is set on the machine body 1 and is located on one side of the conveyor belt 306. The positioning block 208 is connected to the output end of the positioning cylinder 207. The positioning block 208 can lock or release its mutual bonding relationship with the corresponding transport unit. The output end of the positioning cylinder 207 extends, thereby pushing the positioning block 208 to move above the conveyor belt 306. As the conveyor belt 306 rotates, any one of the transport units will be mutually bonded with the positioning block 208, indicating that at this time the opening of the packaging bag has just moved between the bonding plate 203 and the pressing block 204, and the sealing assembly 2 starts to work.

[0034] Furthermore, it should be noted that, in order to ensure that after the bag opening is sealed, the positioning block 208 can release its contact with the corresponding transport unit, allowing the transport belt 306 to continue rotating, the sealing assembly 2 in this solution also includes a detection rod 209, a detection spring 210, and a detection module 211. The detection module 211 is located on the end of the positioning block 208 away from the bonding plate 203. The detection rod 209 is slidably mounted on the pressing block 204, positioned between the bonding plate 203 and the detection module 211, with the end of the detection rod 209 near the bonding plate 203 extending out of the positioning block 208. The sliding direction of the detection rod 209 is parallel to the direction of contact with the bonding plate 203. The telescopic cylinder 206 has the same extension and retraction direction at its output end. The two ends of the detection spring 210 are respectively connected to the detection rod 209 and the pressing block 204. The detection rod 209 can lock or release its pressing engagement with the detection module 211. With this setting, as the positioning block 208 moves closer to the bonding plate 203, the detection rod 209 will first abut against the bonding plate 203. Then, as the positioning block 208 and the bonding plate 203 are in contact, the detection rod 209 will move relative to the positioning block 208 towards the detection module 211 until the detection rod 209 presses the detection module 211, and the detection module 211 starts to work. It should be noted that, since the positioning block 208 and the bonding plate 203 remain in contact for a certain period of time after being bonded together, in order to ensure that the detection module 211 can only control the positioning cylinder 207 to work after the positioning block 208 and the bonding plate 203 separate after the detection rod 209 presses the detection module 211, thereby releasing the bonding relationship between the positioning block 208 and the corresponding transport unit. The detection module 211 and the positioning cylinder 207 are communicatively connected, and the detection module 211 is equipped with a delay command. After the detection rod 209 presses the detection module 211, the detection module 211 starts the delay command. After the delay command ends, it controls the positioning cylinder 207 to retract. The specified delay time is consistent with the time when the pressing block 204 and the bonding plate 203 are bonded together.

[0035] In addition, to ensure the cleanliness of the sealed packaging bags, this solution also includes a sterilization lamp 4, which is installed on the machine body 1 and located at the top of the conveyor belt 306 to sterilize the opening of the packaging bags that are to be sealed.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
