Description

Technical Field

[0001] This utility model belongs to the technical field of food preservation sheet dispensing mechanisms, and in particular relates to a food preservation sheet dispensing mechanism for bread packaging. Background Technology

[0002] The preservation sheets used in bread production are usually called "food preservation cards" or "alcohol preservation cards". Their main function is to inhibit the growth of mold and bacteria by releasing alcohol gas, thereby extending the shelf life of bread.

[0003] Currently, there are two methods for applying preservation chips during bread production. One method involves applying the chips using a machine combined with sensors, which is more expensive and used in large-scale production workshops. The other method involves applying the chips manually, which is used in small and medium-sized production workshops, but is less efficient, prone to errors, and incurs labor costs.

[0004] To address the aforementioned issues, this application proposes a bread packaging preservation sheet dispensing mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a bread packaging preservation chip dispensing mechanism, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a bread packaging preservation chip dispensing mechanism, including a fixing frame;

[0008] The inclined frame has an inclined structure with a protruding front end above the fixed frame. A pusher block is provided above the inclined frame to push out the preservation sheets in sequence. A storage box is provided above the inclined frame for stacking the preservation sheets and for replacement feeding. Friction wheels are provided at the bottom of both the left and right ends of the fixed frame to abut against the transmission belt of the production line and provide driving force to the pusher block.

[0009] The bottom of the storage box is inclined and parallel to the inclined frame. The rear end of the storage box has a baffle to position the stacking angle of the preservation sheets. The front end of the storage box has a positioning hole for the pin to be installed at the front end of the inclined frame. One end of the pin has a rubber ball for fixing the storage box. The storage boxes are arranged at equal intervals to control the dispensing of preservation sheets.

[0010] Furthermore, a sliding plate is provided between the fixed frame and the inclined frame, and sliding rods are arranged at equal intervals on the upper end of the sliding plate and slidably installed inside the push block to control the movement trajectory of the push block.

[0011] Furthermore, the left and right ends of the skateboard are provided with pull ropes, which are slidably installed inside the front and rear ends of the inclined frame, and the skateboard moves forward following the pull ropes.

[0012] Furthermore, a side plate is provided below the top plate of the fixing frame, and a side frame is installed on one side of it, and the pull rope is driven to move by the arc-shaped pressure roller inside the side frame.

[0013] Furthermore, a roller is provided on one side of the side frame and on the lower end of the side plate, and the upper and lower rollers are connected by a belt.

[0014] Furthermore, a friction disc is provided on the outer side of the friction disc shaft below the side plate, located between the side plate and the rotating wheel.

[0015] Furthermore, the inner side of the friction wheel is provided with a lever that intermittently actuates the friction disc to drive the rotating wheel to rotate, thereby driving the arc-shaped pressure roller in the side frame to rotate.

[0016] Furthermore, the interior of the inclined frame and the bottom of the storage box are respectively provided with slide rails and opening slots to provide sliding space for the slide rod.

[0017] This utility model has the following beneficial effects:

[0018] This invention uses a friction wheel combined with a lever to drive the friction disc to rotate intermittently, which in turn drives a pull rope to push out the preservation sheets stacked in the storage box intermittently. This forms a mechanical transmission method for dispensing the preservation sheets, replacing the traditional machine and manual dispensing methods. This controls input costs while ensuring dispensing accuracy suitable for continuous production operations.

[0019] This invention utilizes a storage box to hold preservation sheets, allowing for adjustment of the number of preservation sheets added during packaging operations based on the number of bags in a batch of bread. It is adaptable to bread packaging of various sizes, and the stacking storage box method enables batch storage of preservation sheets. Installation is simple, and a full storage box can be directly replaced after a batch of preservation sheets has been used up, meeting the needs of mass production and packaging of bread.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figures 1-6 As shown, this utility model is a bread packaging preservation chip dispensing mechanism, including a fixing frame 1;

[0033] The inclined frame 2 is an inclined structure with a raised front end above the fixed frame 1. The upper part of the inclined frame 2 is provided with push blocks 4 to push out the preservation sheets for delivery. The upper part of the inclined frame 2 is provided with a storage box 3 for stacking the preservation sheets and for replacement feeding. The bottom of the left and right ends of the fixed frame 1 are provided with friction wheels 18 that abut against the transmission belt of the production line to provide driving force to the push blocks 4.

[0034] The bottom of the storage box 3 is tilted and parallel to the inclined frame 2. The rear end of the storage box 3 is equipped with a baffle 9 to position the stacking angle of the preservation sheets. The front end of the storage box 3 is equipped with a pin 10 installed in the positioning hole 7 at the front end of the inclined frame 2. One end of the pin 10 is equipped with a rubber ball 14 for fixing the storage box 3. The storage box 3 is arranged at equal intervals to control the dispensing of preservation sheets.

[0035] This embodiment provides a mechanism that can replace manual and machine-based food preservation tablet dispensing. The storage box 3 is used to stack and store the food preservation tablets with the front end protruding upwards, which can effectively prevent them from falling off prematurely. Then, the pusher block 4 is used to tilt and push upwards so that the food preservation tablets are dispensed in sequence. This not only controls the cost input but also completes the batch dispensing operation. Moreover, the full storage box 3 can be replaced with an empty food preservation box at any time to ensure the continuity of the batch dispensing operation.

[0036] Among them, a sliding plate 12 is provided between the fixed frame 1 and the inclined frame 2. Slide rods 13 are arranged at equal intervals on the upper end of the sliding plate 12. The slide rods are slidably installed inside the holes below the push block 4, so that when the push block 4 moves obliquely upward, its movement trajectory is still restricted by the slide rods 13 to prevent it from falling off and affecting its use.

[0037] The left and right ends of the slide plate 12 are equipped with pull ropes 5. The pull ropes 5 are slidably installed inside the front and rear ends of the inclined frame 2. The slide plate 12 moves forward with the pull ropes 5. When the storage box 3 is replaced with a full one, the slide plate 12 is pushed backward, which will drive the push block 3 to reset in the opposite direction, and at the same time make the pull ropes 5 rotate in the opposite direction to the initial state.

[0038] Among them, the top plate of the fixed frame 1 is provided with a side plate 11, and a side frame 15 is installed on one side. The arc-shaped pressure roller in the side frame 15 drives the pull rope 5 to move. The middle section of the arc-shaped pressure roller is an arc surface, while the two ends are rubber mechanisms. The rubber areas of the upper and lower arc-shaped pressure rollers press against each other, forming opposite motion trajectories when rotating.

[0039] Among them, a rotating wheel 16 is provided on one side of the side frame 15 and the lower side of the side plate 11. The upper and lower rotating wheels 16 are connected by a belt, and the upper rotating wheel 16 is coaxial with the arc-shaped pressure roller inside the lower part of the side frame 15.

[0040] Among them, the friction disc 17 is provided on the outer side of the rotating shaft of the friction disc 17 below the side plate 11, and the outer side is a rubber ring to increase the friction. The friction disc is located on the outer side of the rotating shaft between the side plate 11 and the rotating wheel 16.

[0041] The friction wheel 18 has a lever 19 on its inner side. When the friction wheel 18 rotates one revolution, it moves the friction disc 17 to make the rotating wheel 16 rotate at a certain angle, thereby causing the arc-shaped pressure roller in the side frame 15 to rotate at a certain angle, which in turn causes the pull rope 5 to move a certain distance, so as to achieve the effect of the push block 3 intermittently pushing out the preservation sheet.

[0042] The inclined frame 2 and the bottom of the storage box 3 are respectively provided with a slide rail 6 and an opening groove 8 to provide sliding space for the slide rod 13. The opening groove 8 allows the storage box 3 to be installed from the front onto the upper part of the inclined frame 2, and allows the push block 3 to be lifted by the bottom plate of the storage box 3, which facilitates the subsequent operation of adding preservation tablets.

[0043] Understandably, this invention breaks away from the traditional methods of manual and machine dispensing, controlling input costs while completing continuous dispensing of preservation chips, and can adjust the dispensing position and quantity according to the number of packaging bags in a batch of bread.

[0044] A specific application of the operation process of this embodiment is as follows: First, the fixing frame 1 is installed on the outside of the bread conveyor line. Then, the storage box 3 is placed on the inclined frame 2, and the pin 10 is inserted into the positioning hole 7 and fixed by the rubber ball 14. Then, the friction wheel 18 is rubbed by the conveyor belt, thereby driving it to rotate. The lever 19 continuously moves the friction disc 17 to make the upper and lower rotating wheels 16 rotate synchronously, thereby driving the upper and lower squeezing rollers on the inside of the side frame 15 to rotate simultaneously, and driving the pull rope 5 to move forward. Finally, the slide plate 12 is moved forward. During the sliding, the push block 4 is continuously raised and is kept connected to the slide plate 12 by the slide rod 13. After this arrangement, the preservation sheets stacked inside the storage box 3 can be put in sequentially. Finally, the full storage box 3 is directly replaced with the empty storage box 3 on the fixing frame 1 to form a long-term continuous feeding operation.
