Description

Technical Field

[0001] This utility model relates to the field of zongzi processing technology, specifically to a vacuum packaging equipment suitable for zongzi processing. Background Technology

[0002] Vacuum packaging equipment suitable for zongzi processing mainly includes fully automatic zongzi vacuum packaging machine, triangular zongzi continuous vacuum packaging equipment, and zongzi stretch film vacuum packaging machine. All three types of equipment can effectively improve the packaging efficiency of zongzi, ensure the hygiene and quality of zongzi, extend the shelf life, and enhance the market competitiveness of the product. When selecting specific equipment, factors such as production scale, product type, and market demand should be considered comprehensively.

[0003] Prior art 1 (application number: CN202321753189.2) discloses a vacuum packaging device suitable for processing zongzi (sticky rice dumplings). The output end of the motor is fixedly mounted on the top of the base plate, and a plurality of zongzi placement cavities are evenly distributed around the outer edge of the top of the support plate. This utility model relates to the field of vacuum packaging technology. This vacuum packaging device for zongzi processing, through the cooperation of the receiving cylinder, push column, heat-sealing strip, and cutting blade, pushes the plastic film bag to the left to heat-seal it. The cutting blade then cuts off the excess plastic film bag edges, reducing subsequent workload. Through the cooperation of the blower, annular tube, guide tube, and inner push plate, when the vacuum-sealed zongzi is rotated to the front, the blower and corresponding solenoid valve open, inflating the corresponding guide tube with air pressure. This air pressure then pushes the inner push plate forward, automatically ejecting the vacuum-sealed zongzi for convenient removal.

[0004] However, in implementing the relevant technology, the following problems were found with the vacuum packaging equipment for zongzi processing: when conveying, vacuuming, and thermoforming zongzi in batches, the work is complicated and cumbersome, the work efficiency is low, and it is also inconvenient to collect them uniformly, which affects their use. Utility Model Content

[0011] A placing structure, which is fixedly connected to the upper end surface of the belt, and is meshed and传动连接 with the outer surfaces of the belt and the gear. (It seems there is a wrong word "传动连接" here, it might be "driven and connected" or other correct expressions. For now, I just keep the original Chinese word.)

[0012] Preferably, one-third of the outer surface of the gear is a serrated structure, and an intermittent drive structure is formed between the gear and the belt, and the drive trajectory installed on it does not intersect with the left and right ends of... (It seems the description here is incomplete. For now, I keep the original Chinese for the part that is not clear.)

[0013] Preferably, the placing structure includes a placing shell, a sliding rod, a return spring, a limiting port and a clamping block. The placing shell is fixedly connected to the upper end surface of the belt. The front and rear side walls of the placing shell are both penetrated and connected with the sliding rod. A return spring is sleeved on the front outer surface of the sliding rod. The end of the sliding rod penetrating inside the placing shell is fixedly connected with the clamping block.

[0015] Preferably, the height dimension of the opening of the limiting port is equal to the height dimension of the splint, and the right inner wall of the splint is inclined, and twice the thickness dimension of the splint is less than the opening front - and - rear width dimension of the limiting port. At the same time, the inner wall of the splint located directly below the vacuum extraction tube is in a semi - circular arc structure.

[0016] Preferably, the output end of the second electric telescopic rod is fixedly connected with a pushing block, and a vacuum extraction tube is installed through the inside of the pushing block, and the vertical central axis of the vacuum extraction tube coincides with the vertical central axis between the splints.

[0021] In this utility model, a placement structure and a material collection plate are provided. The placement structure places the rice dumplings, which facilitates stable conveying of the rice dumplings and makes processing convenient. When the placement structure conveys the rice dumplings to the underside of the belt, the rice dumplings are subjected to gravity and automatically fall downwards, thus making it easy for them to fall onto the material collection plate for unified collection and convenient use.

[0022] In this utility model, a clamping plate and a vacuum tube are provided. The vacuum tube passes through the right end of the clamping plate. The clamping plate uses the extension and retraction of the first electric telescopic rod to squeeze and seal the opening of the zongzi packaging bag, while also facilitating the vacuum tube to pass through the inside of the packaging bag for vacuuming. This makes it easy for the vacuum tube to pass stably through the clamping plate and through the opening of the packaging bag. At the same time, the clamping plate uses a heating strip to perform heat-press sealing treatment on the packaging bag. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figures 1-4 This utility model provides a technical solution for vacuum packaging equipment suitable for zongzi processing: including a machine body shell 1, a material collection plate 2, a motor 3, a gear 4, a belt 5, a placement structure 6, a placement shell 601, a slide rod 602, a return spring 603, a limiting port 604, a clamping block 605, a mounting plate 7, a clamping plate 8, a heating strip 9, a first electric telescopic rod 10, a vacuum tube 11, a pusher block 12, and a second electric telescopic rod 13.

[0031] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 and Figure 4 As shown, one-third of the outer surface of gear 4 is a sawtooth structure, and gear 4 and belt 5 form an intermittent transmission structure. The transmission trajectory of 6 installed on 5 does not intersect with the left and right ends of 1. Turn on the power switch of motor 3, so that belt 5 can intermittently transmit the placement structure 6, which facilitates the stable transmission of the zongzi placed in the placement structure 6 and makes processing convenient.

[0032] Combination Figure 1 and Figure 4As shown, the placement structure 6 includes a placement shell 601, a sliding rod 602, a return spring 603, a limiting port 604, and a clamping block 605. The placement shell 601 is fixedly connected to the upper end surface of the belt 5. The front and rear side walls of the placement shell 601 are both penetrated and connected with the sliding rod 602. A return spring 603 is sleeved on the outer surface of the front end of the sliding rod 602. The end of the sliding rod 602 penetrating inside the placement shell 601 is fixedly connected with the clamping block 605. A limiting port 604 is opened on the upper side wall of the placement shell 601. The sliding rod 602 is in a "dry" - shaped structure. The clamping block 605 forms a telescopic structure inside the placement shell 601 through the sliding rod 602. The inner wall of the upper end of the clamping block 605 is inclined. And the height dimension of the clamping block 605 is lower than the lower opening surface of the limiting port 604. The height dimension of the opening of the limiting port 604 is equal to the height dimension of the clamping plate 8. And the inner wall of the right end of the clamping plate 8 is inclined. And twice the thickness dimension of the clamping plate 8 is less than the width dimension of the opening of the limiting port 604 in the front - and - back direction. The clamping block 605 uses the elasticity of the return spring 603 to expand and contract on the placement shell 601 through the sliding rod 602, so as to facilitate clamping and fixing the packaging bag containing zongzi through the clamping block 605, facilitating stable transmission. At the same time, when the placement structure 6 is transmitted through the belt 5, the clamping plate 8 penetrates through the inside of the limiting port 604, so as to facilitate the clamping plate 8 to clamp the upper opening of the packaging bag, facilitating processing;

[0033] Combined with Figure 1 and Figure 4 As shown, the output end of the second electric telescopic rod 13 is fixedly connected with a push block 12. And a vacuum extraction tube 11 is installed through the inside of the push block 12. And the vertical central axis of the vacuum extraction tube 11 coincides with the vertical central axis between the clamping plates 8. The maximum distance dimension between the outer walls of the clamping plates 8 is equal to the width dimension of the opening of the limiting port 604 in the front - and - back direction. And the length dimension of the clamping plate 8 is greater than the left - and - right width dimension of the placement structure 6. The inner wall of the clamping plate 8 directly below the vacuum extraction tube 11 is in a semi - circular arc structure. Turning on the power switch of the push block 12, the push block 12 drives the vacuum extraction tube 11 to move up and down, so as to facilitate the lower end of the vacuum extraction tube 11 to penetrate between the clamping plates 8 and insert into the opening of the packaging bag, so as to facilitate vacuum extraction processing of the packaging bag. After extraction, the vacuum extraction tube 11 is lifted upward and pulled out from the packaging bag, which is convenient for use. At the same time, the first electric telescopic rod 10 drives the clamping plate 8 to move back and forth at the limiting port 604, facilitating adjustment of the distance dimension between the clamping plates 8 and also facilitating heat - pressing and sealing the opening of the packaging bag with the heating strip 9;

[0034] The lower inner surface of the outer shell 1 is integrally and fixedly connected to the material collection plate 2, and the material collection plate 2 is set at an angle at the lower opening of the outer shell 1. When the placement structure 6 is conveyed to the lower part of the outer shell 1 by the belt 5, it falls onto the material collection plate 2, which facilitates the collection of the packaged zongzi. This is the working process of the vacuum packaging equipment suitable for zongzi processing.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
