Description

Technical Field

[0001] The invention belongs to the technical field of food processing, and in particular relates to a filling injection molding device and a molding method thereof for bread production. Background Art

[0002] As consumers' requirements for product quality increase and market competition intensifies, traditional manual filling methods are gradually being eliminated because they are difficult to ensure consistency and have low efficiency. Therefore, modern filling injection and molding devices have emerged, which can significantly improve the product's appearance quality, taste consistency and production efficiency. In addition, as people pay more attention to healthy eating, manufacturers are also paying more attention to developing new products that can maintain nutrition and provide a good eating experience.

[0003] After searching, the patent with application publication number CN219537315U discloses a filling injection molding device for cereal bread production, including a base, a side plate, a top plate, an electric cylinder, a molding block, a turntable, a material box, a stirring assembly and a conveying assembly. The side plate is fixedly mounted on one end of the top side of the base, the top plate is fixedly mounted on the top side of the side plate, and the material box is fixedly mounted on one side of the side plate. The bread and filling formed in the molding port are discharged from the molding port through the rotation of the turntable to achieve the continuity of bread filling injection. Since the filling injection process is not optimized, there will be certain limitations in use. Due to the differences in ingredients and production processes of different breads, the fluffiness of the filled bread is different. When the texture of the bread is relatively compact, the filling is directly injected into the bread. If the pressure during the injection process is too large or the position of the needle insertion is not accurate enough, the bread may be torn or deformed, resulting in a waste of fillings, thereby affecting the production quality of the bread when the fillings are injected.

The present invention is further described below in conjunction with specific embodiments. The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0028] Embodiment 1: A filling injection molding device for bread production, such as Figure 1-Figure 6As shown, it includes a base 1 and an electric slide rail 2, the base 1 is the assembly carrier of the device, and the electric slide rail 2 is fixedly arranged on the top surface of the base 1; it also includes: a sliding frame 3, which is installed on the electric slide rail 2; three syringes 4 are provided and installed on the sliding frame 3, and the syringes 4 are used to inject stuffing into the produced bread 100 through needle tubes 42; a propping mechanism 5, which is arranged on the side of the sliding frame 3 close to the filling filling, and the propping mechanism 5 includes: an electric push rod 51, which is fixedly installed on the side of the sliding frame 3 facing the filling filling; a driving frame 52, which is fixedly connected to the push rod of the electric push rod 51; a sleeve 53, the number of which is the same as that of the syringe 4, and the needle tube 42 of the syringe 4 slides through the corresponding The sleeve 53 is tightly fitted on the outer wall of the needle tube 42. The driving frame 52 is provided with a stretching member 6, which is used to stretch a certain filling injection space in advance inside the bread 100. The stretching member 6 includes: a slide bar 61, which is provided with two and symmetrically slidably arranged on both sides of the tube wall of the sleeve 53; a stretching bar 62, which is rotatably installed on the front end of each slide bar 61 through a rotating shaft 621, and the stretching bar 62 is tightly fitted and embedded in the outer tube wall at the front end of the sleeve 53. The stretching bar 62 is provided with an oblique groove 622 near the rotating shaft 621; a limiting rod 63, which is symmetrically fixed on the outer tube wall of the sleeve 53, and the limiting rod 63 is respectively located in the oblique groove 622 of the stretching bar 62; a sliding Ring 64 is slidably arranged on the outer wall of sleeve 53, and sliding ring 64 is connected to slide bar 61; connecting frame 65 is fixedly connected to sliding ring 64 on each sleeve 53; electric push rod 2 66 is fixedly installed on driving frame 52, and the push rod of electric push rod 2 66 is connected to connecting frame 65, and the needle tubes 42 of multiple syringes 4 on sliding frame 3 are driven by electric slide rail 2 to synchronously penetrate into the bread 100 to be injected with stuffing, and at this time, the opening strip 62 at the needle head of the needle tube 42 will also be synchronously penetrated into the bread 100, and the electric push rod 2 66 is first activated, and the electric push rod 2 66 pulls the slide bar 61 through the connecting frame 65, so that the slide bar 61 pulls the opening strip 62, and then Under the limit of the limit rod 63, the pulled expansion strip 62 will rotate under the guidance of the inclined groove 622, so that the expansion strip 62 can expand a certain space for filling materials in the bread 100 without damaging the bread 100. After the expansion is completed, the electric push rod 2 66 acts on the connecting frame 65 in the opposite direction, so that the slide bar 61 pushes the expansion strip 62 to return to the sleeve 53, and then the electric push rod 1 51 drives the driving frame 52 and the sleeve 53 to push out the bread 100, so that the needle tube 42 stays in the expanded space of the bread 100, and then the piston 41 on the syringe 4 is pushed to complete the filling of a certain filling into the expanded space of the bread 100, thereby improving the quality of the filling of the bread 100.

[0029] like Figure 2 and Figure 3As shown, a limiting frame 31 is fixedly provided on one side of the sliding frame 3 close to the needle tube 42 of the syringe 4, and a plurality of placement grooves are provided on the limiting frame 31. The limiting frame 31 supports and limits the front end of the barrel of the syringe 4, so that a plurality of syringes 4 can be stably placed flat on the sliding frame 3. The barrel of the syringe 4 is transparent and has obvious scales 43 thereon. By observing the scales 43 on the syringe 4 and pulling the piston 41, the filling in the syringe 4 can be accurately added to the bread 100, avoiding too much or too little filling in the syringe 4, and making the filling added to each bread 100 as consistent as possible.

[0030] like Figure 1 and Fig.10 As shown, it also includes a feeding piece 10, which includes a belt conveyor 101 and a limiting clamp 103. The belt conveyor 101 is arranged on the front side of the base 1, and is used to automatically convey the bread 100 to the filling position. The limiting clamps 103 are arranged at intervals on the conveyor belt 102 of the belt conveyor 101 in the circumferential direction. The limiting clamps 103 are used to place and limit the bread 100 on the conveyor belt 102. Through the belt conveyor 101 cooperating with the electric slide rail 2 and the limiting clamp 103 on the bread 100, the injector 4 on the sliding frame 3 can automatically complete the filling operation of the bread 100 on the conveyor belt 102.

[0031] When the device is used to inject fillings into bread 100, first the belt conveyor 101 starts to operate, and the bread 100 placed in the limiting clamp 103 is automatically conveyed to the filling position on the front side of the syringe 4. When the bread 100 reaches the designated filling position, the belt conveyor 101 is closed, and then the electric slide rail 2 is started. The electric slide rail 2 drives the sliding frame 3 and the syringe 4 and the opening mechanism 5 thereon to move toward the bread 100 synchronously, so that the needle tube 42 of the syringe 4 and the outer sleeve 53 synchronously and accurately penetrate into the corresponding injection position inside the bread 100. At this time, the electric slide rail 2 is closed and the electric push rod 2 66 is enabled. The push rod of the electric push rod 2 66 contracts and pulls the connecting frame 65 and the slide bar 61, so that the slide bar 61 pulls the opening bar 62 through the rotating shaft 621. The pulled opening bar 62 rotates along the inclined groove 622 thereon under the limit of the limiting rod 63, so that the opening bar 62 can be opened without damaging the bread 100. In the case of the bread 100 structure, a certain space is pre-opened inside the bread 100 to prepare for the subsequent injection of fillings. Once the opening strip 62 completes the opening of the bread 100, the push rod of the electric push rod 2 66 is reset and pushes the connecting frame 65 and the slide bar 61, so that the slide bar 61 drives the opening strip 62 to rotate and reset to the outer wall of the sleeve 53, and then the electric push rod 1 51 is activated. The electric push rod 1 51 drives the sleeve 53 to push out the bread 100 through the driving frame 52. At the same time, the needle tube 42 of the syringe 4 stays in the opened space of the bread 100. Finally, when the piston 41 on the syringe 4 is manually pushed, by observing the scale 43 on the syringe 4, the filling inside the syringe 4 is accurately injected into the pre-opened space of the bread 100 through the needle tube 42, providing sufficient accommodating space for the filling, which helps to evenly distribute the filling inside the bread 100 and improve the quality of the filling injected into the bread 100.

[0032] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, a kneading mechanism 7 is provided on the top of the base 1, and the kneading mechanism 7 is used to knead the puncture holes on the bread 100. The kneading mechanism 7 includes: an electric push rod 3 71, which is fixedly installed on the top of the base 1; a mounting frame 72, which is fixedly installed on the push rod of the electric push rod 3 71; arc blocks 73, the number of which is consistent with that of the sleeve 53 and is fixedly arranged on the mounting frame 72 at intervals, and a through hole for adapting to the sleeve 53 is opened in the arc block 73, and the sleeve 53 slides through the through hole in the corresponding arc block 73, and a slide groove 731 is provided on the top surface of the arc block 73; a sliding rod 74, two sliding rods 74 are symmetrically slidably installed on the front arc surface of the arc block 73, and the sliding rod 74 and the slide groove 731 of the arc block 73 are slidably matched; a pushing block 75, which is fixedly arranged on the rod body of the sliding rod 74, and the pushing block 75 protrudes toward the arc surface on one side of the corresponding sleeve 53; a micro push rod 76, which has two and The push rod of the micro push rod 76 is symmetrically hinged on the top of the arc block 73, and is hinged on the sliding rod 74 on the same side. Before the needle 42 of the syringe 4 pierces the bread 100, the electric push rod 3 71 drives the arc block 73 on the mounting frame 72 to approach the bread 100, so that the pushing block 75 is slightly pressed on the punctured surface of the bread 100. After the needle 42 on the syringe 4 completes the filling of the bread 100, the electric slide rail 2 drives the needle 42 to be pulled out of the bread 100, and the two micro push rods 76 on the arc block 73 are synchronously activated, so that the micro push rod 76 pushes the sliding rod 74 to move along the slide groove 731 of the arc block 73, and the pushing blocks 75 on the two sliding rods 74 will synchronously perform an inner clamping action at the puncture hole of the bread 100 to close the puncture hole on the surface of the bread 100, thereby preventing the filling added in the bread 100 from flowing out of the puncture hole.

[0033] In order to ensure that the surface of the bread 100 after the filling is added is kept as intact as possible, by activating the electric push rod 3 71, the push rod of the electric push rod 3 71 is extended and drives the mounting frame 72 to approach the bread 100, so that the two pushing blocks 75 on the arc block 73 are slightly squeezed around the puncture hole of the bread 100 to preliminarily locate the kneading position on the bread 100. After the syringe 4 completes the injection of the filling into the bread 100, as the electric slide rail 2 drives the needle tube 42 of the syringe 4 to be completely pulled out of the bread 100, the micro push rod 76 is synchronously activated. The micro push rod 76 pushes the sliding rod 74 to move along the slide groove 731 of the arc block 73 through the push rod, so that the pushing block 75 on the sliding rod 74 completes an inner clamping action at the puncture hole of the bread 100, thereby effectively closing the puncture hole on the surface of the bread 100 and preventing the injected filling from leaking out from the opening, thereby ensuring the integrity and quality of the appearance of the bread 100.

[0034] Embodiment 2: Based on embodiment 1, Figure 1 and Fig. 9As shown, a material box 8 is assembled on the top of the sliding frame 3, and the material box 8 is used to store the filling to be filled. A feeding pipe 81 is connected between the bottom of the material box 8 and the syringe 4. The filling prepared in the material box 8 is continuously added to the syringe 4 through the feeding pipe 81, saving the tedious operation of manually adding filling to each syringe 4 individually.

[0035] like Figure 1 and Fig. 9 As shown, it also includes a filling mechanism 9, which includes a one-way valve 1 91, a one-way valve 2 92, a mounting plate 93, a cylinder 94 and a connecting plate 95. The feeding tube 81 is provided with a one-way valve 1 91, and the needle tube 42 of the syringe 4 is provided with a one-way valve 2 92. The sliding frame 3 is fixedly connected to the side of the needle tube 42 of the syringe 4, and a cylinder 94 is provided on the mounting plate 93. A connecting plate 95 is fixedly connected to the telescopic rod of the cylinder 94. The connecting plate 95 is connected to the pistons 41 of multiple syringes 4. The cylinder 94 drives the piston 41 to push and pull operations in the syringe 4 through the connecting plate 95. Under the action of the one-way valve 1 91 and the one-way valve 2 92, the filling in the material box 8 can be added to the syringe 4, and the filling in the syringe 4 can be filled into the bread 100 through the needle tube 42.

[0036] like Fig. 9 As shown, the one-way valve 1 91 is for the feeding tube 81 to unidirectionally conduct to the syringe 4, and the one-way valve 2 92 is for the syringe 4 to unidirectionally conduct to the needle tube 42. When the piston 41 is pulled out on the syringe 4, the one-way valve 2 92 cannot be conducted, so that the filling in the material box 8 can flow through the feeding tube 81 and the one-way valve 1 91 and then be replenished into the syringe 4. When the piston 41 is pushed into the syringe 4, the one-way valve 1 91 on the feeding tube 81 cannot be conducted, and the filling in the syringe 4 can only flow from the one-way valve 2 92 to the needle tube 42, and the filling operation is performed into the bread 100 through the needle tube 42.

[0037] In order to improve the processing efficiency of batch filling of bread 100, the prepared filling is added into the material box 8 in advance, thereby continuously feeding the multiple syringes 4 on the sliding frame 3 at the same time through the feeding tube 81. When the filling inside the syringe 4 needs to be filled, the cylinder 94 drives the piston 41 to be pulled outward through the mounting plate 93, so that a suction negative pressure is formed inside the syringe 4. At this time, since the one-way valve 2 92 at the needle tube 42 of the syringe 4 cannot be conducted, the one-way valve 1 91 can be conducted to the syringe 4, and the filling in the material box 8 is allowed to flow from the feeding tube 81 to the syringe 4. On the contrary, when the filling in the syringe 4 is about to be injected into the bread 100, the piston 41 is driven inwardly by the cylinder 94, and the one-way valve 1 91 can prevent the filling from returning from the feeding tube 81 to the material box 8, ensuring that the filling in the syringe 4 can only enter the needle tube 42 through the one-way valve 2 92, and finally be accurately injected into the preset space of the bread 100, thereby saving the need for manual intervention in feeding, improving the efficiency and consistency of production, and also ensuring the consistency and accuracy of the amount of filling contained in each bread 100.

[0038] A filling injection molding method for bread production, the specific steps are as follows: S1, the belt conveyor 101 is started, so that the bread 100 carried by the limit clamp block 103 moves to the predetermined filling position of the injector 4, and the electric push rod 3 71 drives the arc block 73 to approach the surface of the bread 100 through the mounting frame 72, so that the push block 75 on the arc block 73 is pressed on the surface of the bread 100, and the puncture hole on the bread 100 is prepared to be closed; S2, the electric slide rail 2 drives the syringe 4 to penetrate the bread 100, and the electric push rod 2 66 pulls the slide bar 61 through the connecting frame 65, so that the opening bar 62 rotates to open the space inside the bread 100 and then resets, and then the piston 41 of the syringe 4 is pushed by the cylinder 94, and with the cooperation of the one-way valve, the needle tube 42 is used to accurately inject the filling into the bread 100; S3, after the filling is injected, the sliding frame 3 returns to the starting position, the micro push rod 76 drives the pushing block 75 to close the puncture holes on the bread 100 to prevent leakage, the belt conveyor 101 transfers this batch of bread 100 to the next process, and the forming device prepares to process the next batch of bread 100.
