Description

Technical Field

[0001] The invention relates to a pastry machine, in particular to a rotary pastry moulding machine, belonging to the technical field of food production and processing equipment. Background Art

[0002] In order to achieve better sales of cakes, cakes must not only taste good, but also have beautiful appearance. In order to make cakes produced in batches have beautiful appearance, the traditional method is usually to manually put the material blocks (usually a mixture of flour, sugar, oil, eggs, dairy products, etc.) into the mold, and obtain the prefabricated material of the specified shape through molding, and then manually open the mold to take out the prefabricated material. This method of processing cakes has low production efficiency, high labor intensity, high labor costs, and is unhygienic. Therefore, people invented the pastry molding line, which puts the material block on the conveyor belt of the assembly line. When the material block runs to the corresponding position of the mold, the sensor senses it and controls the mold to press down to mold the material block. If the shape of the pastry is more complicated and special, it cannot be directly ejected from the mold after molding. The mold needs to be divided into two or even four templates, each of which is driven by a cylinder. When the material block runs to the corresponding position of the mold, each template of the mold is in an open mold state and moves downward to the material block. The template then molds the material block from all four sides. Finally, each template opens and rises to allow the formed pastry to be ejected from the mold. And continue to transport forward to the next process, but the structure has the following disadvantages: 1. Each template is opened first, and then the four sides are molded towards the center of the material block. During the mold closing process (not completely closed), the material block has been squeezed, and the material of the material block is easily squeezed into the gap between the templates, thereby forming flash and affecting the appearance of the pastry; 2. When the molded pastry is transported to the next process on the conveyor belt, since the pastry is still relatively soft at this time, it is easy to cause deformation if it is directly grasped by a robot arm, and it is inconvenient to grasp, especially for some pastries with a larger bottom area (such as tower-shaped), which are more firmly attached to the conveyor belt and more difficult to grasp. Summary of the invention

[0018] Furthermore, the opening and closing device includes a clamping cylinder 291 , which is fixed to the lower head 27 of the double-headed piston rod. A clamping claw 292 is provided on the clamping cylinder 291 , and the clamping claw 292 is fixedly connected to the outer wall of the template 29 .

[0019] Furthermore, an upper connecting plate 221 is provided on the locking cylinder 22, a positioning rod 222 is provided on the upper connecting plate 221, the positioning rod 222 is fixed to the upper connecting plate 221 via a fastener, a positioning groove 223 is provided on the outer wall of the positioning rod 222, a lower connecting plate 224 is provided on the double-head clamping cylinder 2, a through hole 225 is provided in the lower connecting plate 224, a positioning bead 226 and a third spring 227 are provided on one side of the lower connecting plate 224 located at the through hole 225, and the positioning bead 226 cooperates with the positioning groove 223. When the double-head mold clamping cylinder 2 drives the soft mold 28 and the clamping seat 25 to mold the cake downward, the double-head piston rod upper head 21 of the double-head mold clamping cylinder 2 also drives the clamping cylinder 22, the upper connecting plate 221, and the positioning rod 222 to move downward. At this time, the positioning groove 223 on the outer wall of the positioning rod 222 moves downward and squeezes the positioning bead 226 inward (the upper edge of the positioning groove 223 is slightly lower than the positioning bead by 0.2-0.3mm at this time, and the two are still in a matching state, as shown in the attached figure).

Under the guidance of the arc-shaped guide rail 142 which is inclined upward, the ejector rod 342 is gradually ejected upward, and the ejector rod 342 drives the molded pastry to be pushed upward, so that the bottom of the pastry is out of contact with the fixing rod 34 (even if a circle of the bottom of the pastry is exposed), so as to facilitate the subsequent robot or worker to clamp the pastry from the bottom, and avoid directly taking it from the upper side wall of the pastry to cause its deformation.

[0022] Furthermore, a steel ball 346 is disposed under the push rod 342, and the steel ball 346 cooperates with the guide rail 142. With the steel ball 346, when the push rod 342 slides along the guide rail 142, wear is reduced and the service life is increased.

Finally, the motor 12 drives the first set of material discharge and molding ejection assembly 3 to rotate to the fourth station, and the steel ball 346 at the bottom of the ejector rod 342 is out of cooperation with the guide rail 142. The second spring 345 pushes the fixed block 344 and the ejector rod 342 to reset downward under the action of the restoring force. At the same time, the piston rod of the unlocking cylinder 16 drives the push plate 17 to move upward. The push plate 17 pushes the push rod 320 and the unlocking ring 329 to move upward, and the unlocking ring 329 cooperates with the hook 352 on the inner wall of the locking plate 351. Under the action of the unlocking ring 329, the hook 352 is disengaged from the hook 323 on the outer wall of the lower material chamber seat 32. At this time, the first spring 33 pushes the upper material chamber seat 31 and the locking sleeve 35 to reset upward under the action of the restoring force, so that the material chamber 343 is formed again between the upper material chamber seat 31 and the fixing rod 34 and the ejector rod 342, which is convenient for people or robots to put the material block 13 into the material chamber 343, preparing for the next molding action. The present invention relates to a rotary pastry molding machine. First, a material block 13 is placed in a material chamber 343 formed by a material chamber seat 31 of a material discharge and molding ejection assembly 3. Only the upper half of the material block 13 is exposed, while the lower half is in the material chamber 343. When the mold (soft mold 28 or hard mold 44) ​​is molded downward in a closed mold state, the material at the bottom of the material block 13 will not overflow from the gap between the mold and the material chamber seat 31. When the mold gradually pushes the material chamber seat 31 downward, the entire material block 13 can be squeezed into the mold, thereby avoiding overflow and flash. Second, the mold molds the material block 13 in a closed mold state, so that flash will not be formed around the formed pastry, ensuring its beautiful appearance. Third, after the pastry is molded, the ejector rod 342 ejects the pastry upward, and the bottom center of the pastry contacts the ejector rod 342.The bottom of the cake is suspended around the edges, making it easy for humans or robots to take it out from around the bottom of the cake to prevent the cake from deforming.
