[0001] The utility model relates to prefabricated vegetable packing technical field, concretely relates to a prefabricated vegetable ration automatic packing machine. BACKGROUND

[0002] The prefabricated vegetable ration automatic packing machine is a device that can be used for automatic packing of prefabricated dishes, and can complete the whole process from raw material distribution, quantitative filling to packaging on the production line, greatly improving the production efficiency, reducing manual operation, and ensuring the accuracy and consistency in the packaging process. The prefabricated vegetable ration automatic packing machine can accurately control the quantity of dishes in each packaging bag according to the preset distribution requirements through accurate quantitative devices, avoiding errors that may occur in manual operation and ensuring the consistency of the contents in each packaging bag.

[0003] Chinese authorized patent publication number CN222663832U discloses a prefabricated vegetable ration packing machine, which comprises a rack, an operation table and an operation box are arranged on the rack, the operation box is arranged on one side of the operation table, a placing rack is slidably arranged on the operation table, a receiving groove is arranged on the top of the placing rack, a weighing module is arranged in the groove, a stirring assembly for stirring prefabricated dishes and a plastic sealing assembly for sealing prefabricated dish packaging boxes are arranged on the corresponding positions above the top of the rack and the placing rack slidably arranged on the operation table. The prefabricated dish ration packing machine can realize quantitative discharge of prefabricated dish raw materials through the cooperation of the weighing module and the stirring assembly, and can facilitate packaging and sealing operations under the action of the plastic sealing assembly. The overall structure is simple in design, has high applicability for some small-scale supermarkets, restaurants and other businesses that have prefabricated dish production and manufacturing needs, is convenient for users to operate and adjust, and meets different use requirements.

[0004] In the above-mentioned patent, the stirring assembly discharge pipe of the prefabricated dish ration packing machine penetrates the top of the rack, and the lower end is directly suspended above the placing rack. Due to the limitation of the height of the rack and the fixed installation position of the placing rack, the distance between the discharge port and the packaging box on the placing rack is a fixed value, which is difficult to adjust according to actual use requirements. When a packaging box with a small height is used, the distance between the discharge port and the box opening is too far. For granular prefabricated dishes such as diced radish and corn kernels, they are easily affected by air flow and deviate from the box opening during falling, scattering on the placing rack or operation table, and destroying the quantitative accuracy. It will also pollute the equipment and packaging environment. Therefore, we propose a prefabricated dish ration automatic packing machine. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0022] In order to further understand the features, technical means and specific purposes and functions reached by the utility model, the utility model is further described in detail in combination with the drawings and specific embodiments.

[0023] See Figures 1 to 3As shown, a pre-prepared food ration automatic packaging machine comprises a canning device 1, a sealing device 11 fixedly installed on one side of the canning device 1, a hopper 12 fixedly installed on the canning device 1, a discharge pipe 13 fixedly connected to the lower side of the hopper 12, a discharge port 14 arranged below the discharge pipe 13, an extension piece 2 arranged between the discharge pipe 13 and the discharge port 14, and the extension piece 2 being detachably connected to the discharge pipe 13 and the discharge port 14 on both sides; a indicating piece 21 is detachably connected to one side of the discharge port 14, a through slot 22 is formed on the side of the discharge pipe 13 close to the indicating piece 21, and the indicating piece 21 is in sliding fit with the through slot 22; and an adjusting mechanism for controlling the extension piece 2 to realize the stretching action is arranged between the discharge pipe 13 and the discharge port 14.

[0024] Specifically, the extension piece 2 is preferably a deformable folded bellows. The indicating piece 21 is preferably a measuring scale. The cross-sectional size of the indicating piece 21 matches the cross-sectional size of the through slot 22.

[0025] When the pre-prepared food ration automatic packaging machine needs to adjust the distance between the discharge port 14 and the packaging box, the extension piece 2 can be stretched by the adjusting mechanism, and the adjusting mechanism can simultaneously push the discharge port 14 to move downward, so as to realize the dynamic adjustment of the distance.

[0026] For packaging boxes of different height specifications, the precise distance adaptation can be realized by the downward movement of the discharge port 14: for packaging boxes with larger height, the downward movement amount of the discharge port 14 is appropriately reduced to shorten the distance, so as to avoid the collision between the material and the edge of the box opening during the material discharging process, thereby preventing the material from overflowing; for packaging boxes with smaller height, the downward movement amount of the discharge port 14 is increased to control the distance within a reasonable range, so as to prevent the granular material from being scattered outside the box due to air flow interference when falling, thereby meeting the differentiated needs of packaging pre-prepared food of different specifications.

[0027] For pre-prepared food with different fluidity, the quantitative accuracy can be ensured by adjusting the distance by the downward movement of the discharge port 14: for sticky sauce pre-prepared food, the downward movement of the discharge port 14 shortens the distance, which can reduce the wall residue of the sauce at the pipe opening of the discharge pipe 13, and reduce the weight error caused by the dripping of the residual sauce to the operation table; for liquid or easily flowing pre-prepared food, a reasonable downward movement distance can avoid the splashing of the material due to the too long falling distance, and ensure that the material falls accurately into the packaging box.

[0028] Meanwhile, the indicating piece 21 is simultaneously driven to slide along the through slot 22 during the downward movement of the discharge port 14, and the operator can directly obtain the downward movement distance of the discharge port 14 by observing the distance of the indicating piece 21 passing through the through slot 22, without the need of additional measuring tools, so as to quickly judge whether the current distance matches the preset value of the packaging box of different height, which not only avoids the large distance deviation caused by blind adjustment, but also prevents the structure deformation of the supporting assembly caused by the excessive stretching of the extension piece 2, or the collision between the discharge port 14 and the packaging box caused by the too small distance, thereby ensuring the structural stability and operation safety of the equipment.

[0029] Referring to Figures 2 to 5 As shown in the figure, the adjusting mechanism comprises a hand wheel 23 and a support assembly; the hand wheel 23 is rotatably arranged on one side of the discharge pipe 13 close to the stretching member 2; the support assembly is arranged between the discharge pipe 13 and the discharge port 14, and is used to provide structural support for the stretching action of the stretching member 2; the adjusting mechanism further comprises a transmission assembly and a limiting assembly; the transmission assembly is arranged between the hand wheel 23 and the support assembly, and is used to transmit the rotating force of the hand wheel 23 to the support assembly; the limiting assembly is arranged on the support assembly, and is used to limit the moving stroke of the support assembly.

[0030] Specifically, when the pre-prepared food ration automatic packaging machine needs to adjust the distance between the discharge port 14 and the packaging box, the operator rotates the hand wheel 23, and the hand wheel 23 transmits the rotating force to the two sets of support assemblies through the transmission assembly, drives the support assemblies to move synchronously and drives the stretching member 2 to stretch. During the stretching process of the stretching member 2, the support assembly moves downward along the axis to drive the discharge port 14, thereby adjusting the distance between the discharge port 14 and the packaging box.

[0031] At the same time, the limiting assembly arranged on the support assembly also works synchronously, and through the pre-set stroke limiting structure, the support assembly is prevented from driving the discharge port 14 to move beyond the pre-set downward movement range, so as to avoid the collision between the discharge port 14 and the packaging box or the damage of the stretching member 2 and the support assembly structure due to excessive downward movement, thereby ensuring the safety and stability of the distance adjustment process.

[0032] Referring to Figures 3 to 5 As shown in the figure, the support assembly comprises a screw rod 24 and a connecting pipe 25; the screw rod 24 is rotatably arranged on the discharge pipe 13; the connecting pipe 25 is sleeved on the outer side of the screw rod 24, and the lower end of the connecting pipe 25 is fixedly connected with the discharge port 14; the inner side of the connecting pipe 25 is fixedly connected with a threaded pipe 26, and the threaded pipe 26 is threadedly connected with the screw rod 24; the transmission assembly comprises a toothed disc 27 and a toothed ring 28; the toothed disc 27 is rotatably arranged on the discharge pipe 13, and the toothed disc 27 is fixedly connected with the screw rod 24; the toothed ring 28 is rotatably arranged on the discharge pipe 13, and the toothed ring 28 is engaged with the toothed disc 27; the limiting assembly comprises a sliding groove 29 and a sliding block 210; the sliding groove 29 is formed on the side of the connecting pipe 25 away from the threaded pipe 26; the sliding block 210 is slidably arranged in the connecting pipe 25, and the sliding block 210 is in sliding fit with the sliding groove 29; one end of the sliding block 210 is rotatably connected with the screw rod 24.

[0033] Specifically, the sliding groove 29 and the sliding block 210 form a sliding guide pair.

[0034] Rotating the hand wheel 23 drives the toothed ring 28 to rotate around its own axis; since the toothed ring 28 is in meshing fit with the two sets of toothed discs 27, the rotating force of the toothed ring 28 is transmitted to the two sets of toothed discs 27 through meshing transmission, thereby driving the two sets of toothed discs 27 to rotate synchronously.

[0035] When the gear disc 27 rotates, the output end of the gear disc 27 drives the corresponding screw rod 24 to rotate synchronously; since the screw rod 24 is threadedly connected with the threaded pipe 26, the circumferential rotation movement of the screw rod 24 is converted into the axial linear movement of the threaded pipe 26 through thread transmission, so that the threaded pipe 26 drives the connecting pipe 25 to stably move downward along the outer side of the screw rod 24, and the connecting pipe 25 further drives the discharge port 14 to move downward synchronously; in this process, the discharge port 14 drives the stretching member 2 to complete the stretching action.

[0036] Meanwhile, the sliding block 210 connected with the screw rod 24 rotates and slides along the preset sliding groove 29; when the sliding block 210 moves to the top end of the sliding groove 29, the sliding groove 29 blocks the sliding block 210, limits the continuous movement of the sliding block 210, and prevents the connecting pipe 25 from continuing to move, thereby preventing the connecting pipe 25 from completely separating from the screw rod 24, and guaranteeing the stability of the spacing adjustment process between the discharge port 14 and the packaging box.

[0037] Working principle: rotate the hand wheel 23, so that the screw rod 24 rotates synchronously, so that the connecting pipe 25 moves downward along the outer side of the screw rod 24, and the stretching member 2 completes the stretching action, so that the connecting pipe 25 further drives the discharge port 14 to move downward synchronously, so as to realize the adjustment of the spacing between the discharge port 14 and the packaging box, and in the process of moving the discharge port 14 downward, the indicating member 21 is driven to slide along the through groove 22 synchronously, and the operator observes the distance through which the indicating member 21 passes through the through groove 22.

[0038] The above embodiment only expresses one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
