Description

Technical Field

[0001] This invention relates to the field of sandwich cookie production technology, and in particular to an ultra-thin cookie suction cup sandwich machine. Background Technology

[0002] Biscuits are baked with flour and water or milk without yeast. They can be used as a storage food for travel, sailing, and mountain climbing. Of course, they are also one of the most common snacks people eat every day. They are characterized by their long shelf life, portability, and variety of flavors, and are loved by many people. Sandwich biscuits consist of at least two biscuits on the top and bottom sides and a filling layer in the middle. Multi-layered sandwich biscuits offer a wider variety of flavor combinations and are quite popular. With the continuous development of technology, current biscuit production is completed on automated production lines. For example, existing published documents CN113767946B - a sandwich biscuit production equipment and method and CN114304207B - a sandwich biscuit production cream conveying and spreading device and its usage method both disclose a device for automated sandwich biscuit production. However, in actual use, the above-mentioned production devices still have the following shortcomings: 1. Existing sandwich cookie production equipment mainly uses conveyor rails or clamps for feeding, but this is not well-suited for producing ultra-thin cookies. When feeding with these devices, the cookies are prone to breakage, resulting in a decrease in the quality of the finished product. Moreover, the existing production equipment has low overall production efficiency and poor practicality. 2. Existing sandwich cookie production equipment mainly uses air pressure to squeeze the filling into the cookie during the slurry injection process. However, due to the wide variety of fillings, the traditional slurry injection method is not suitable for effectively feeding different fillings, and it is also difficult to effectively control the amount of slurry injected, resulting in poor overall practicality. Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0015] The present invention has the following beneficial effects: 1. When in use, this sandwich machine uses a suction plate to feed the biscuits instead of traditional conveyor rails or clamps, which can effectively prevent damage to the biscuits. The positioning pins guide the biscuits during suction, preventing them from being lifted up and falling due to adhesion between them, thus providing good protection. The feeding mechanisms on both sides of the conveyor belt, together with two bidirectional motors in the same group, synchronously drive the same traction rope to move back and forth, so that the transfer mechanism can alternately transfer the biscuits on the two feeding mechanisms in the same group to the conveyor belt. This can achieve continuous and uninterrupted alternating feeding, effectively improving production efficiency and making it highly practical.

[0016] 2. When using this sandwich machine, after the slurry enters the discharge box through the feeding hopper, the rotation of the screw rod can drive the pusher plate to move back and forth. During the movement, the arc-shaped surface design can move the slurry along one side of the dispensing plate to the other side. During this movement, the slurry will be injected into the dispensing tank in a quantitative manner, realizing precise material distribution before quantitative feeding. After the slurry fills the dispensing tank, for thinner slurries, the slurry will be sprayed directly through the dispensing nozzle under the action of gravity. For thicker slurries, a certain amount of air can be blown in through the air inlet pipe to squeeze the slurry in the dispensing tank out through the dispensing nozzle. Attached Figure Description

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example 1

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 This is the first embodiment of the present invention. This embodiment provides an ultra-thin biscuit suction cup sandwich machine. When the suction cup sandwich machine is in use, the feeding mechanism 200 is used by the staff to feed the biscuits and temporarily store them. The transfer mechanism 300 transfers the biscuits on the feeding mechanism 200 to the conveyor belt 101. The conveyor belt 101 carries the biscuits to the sandwich feeding mechanism 400 for slurry injection. After the slurry injection is completed, the conveyor belt 101 carries the biscuits to another transfer mechanism 300. The transfer mechanism 300 transfers the biscuits again to cover the slurry, completing the production of sandwich biscuits. After the production is completed, the conveyor belt 101 carries the biscuits to the assembling mechanism 500. The assembling mechanism 500 performs assembling operations on the biscuits, including at least pressing and adjusting the position.

[0034] Specifically, it includes: a conveying mechanism 100, comprising a conveyor belt 101 and an outer protective frame 102 disposed on the outer side of the lower end of the conveyor belt 101; rollers slidably sleeved at both ends of the inner side of the conveyor belt 101, and one of the rollers being driven by a third drive motor to move the conveyor belt 101 for conveying; a feeding mechanism 200, comprising a support frame 201, a bearing platform 202, a loading plate 203, and a mounting frame 204; a material transfer mechanism 300 located directly above the conveyor belt 101, comprising an outer protective shell 301, a material transfer plate 302 located at the lower end of the inner side of the outer protective shell 301, a second bidirectional motor 303 fixed on the top surface of the outer protective shell 301, and a traction rope 304 fixedly connected to the outer side wall of the outer protective shell 301; a sandwich conveying mechanism 400 disposed directly above the conveyor belt 101; and a material straightening mechanism 500 disposed above the conveyor belt 101 on one side of the material transfer mechanism 300, and the material straightening mechanism 500 being disposed near the output end of the conveyor belt 101; Preferably, two feeding mechanisms 200 are symmetrically arranged on both sides of the conveyor belt 101 to form a group of feeding mechanisms 200. Then, n groups of feeding mechanisms 200 are arranged in an array along the conveying direction of the conveyor belt 101, and n≥2, so as to realize the production of at least one layer of sandwich biscuits. A transfer mechanism 300 is arranged between two feeding mechanisms 200 in the same group, and a sandwich conveying mechanism 400 is arranged between two adjacent transfer mechanisms 300.

[0035] See details Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the mounting frame 204 is fixed on the top surface of the support frame 201 on the side away from the conveyor belt 101. The mounting frame 204 is fixed with a first bidirectional motor 204a. The two first bidirectional motors 204a in the same group synchronously drive the same traction rope 304 to reciprocate so that the transfer mechanism 300 can alternately transfer the biscuits on the two feeding mechanisms 200 in the same group to the conveyor belt 101. Specifically, a first rotating shaft 204b is fixed to the output end of the first bidirectional motor 204a, and first I-shaped wheels 204b-1 are symmetrically fixed to both ends of the first rotating shaft 204b. The same traction rope 304 is wound around two first I-shaped wheels 204b-1 aligned on both sides of the conveyor belt 101, and the two ends of the traction rope 304 are respectively fixed to the two side walls of the outer shell 301. Guide rail rods 201a are symmetrically arranged on both sides of the outer shell 301, and the two ends of the guide rail rods 201a are fixed to the top surface of two support frames 201 in the same group. A sliding block 301a with clearance fit on the top surface of the guide rail rod 201a is fixed on the bottom surface of the top plate of the outer shell 301, so as to realize the limiting and guiding of the movement of the outer shell 301. In use, the above-mentioned setup enables the first rotating shaft 204b to rotate through the operation of the first bidirectional motor 204a, thereby enabling the rotation of the two first I-shaped wheels 204b-1 on the same first rotating shaft 204b. Through the traction rope 304 wound around the first I-shaped wheel 204b-1, the rotation of the first rotating shaft 204b enables the traction rope 304 to move, thereby driving the outer protective shell 301 to reciprocate along the guide rod 201a. Finally, the material transfer mechanism 300 alternately transfers the biscuits on the two feeding mechanisms 200 in the same group to the conveyor belt 101. Example 2

[0036] Reference Figure 6 , Figure 7 and Figure 8 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that, in order to better implement the present invention, the structure of the material transfer mechanism 300 for transferring materials is described in detail.

[0037] Specifically, a lifting plate 302a is provided directly above the transfer plate 302, and the four corners of the transfer plate 302 are fixedly connected to the lifting plate 302a through connecting columns 302a-1. The two sides of the lifting plate 302a are symmetrically spirally sleeved with screw columns 301b. The upper end of the screw column 301b is rotatably connected to the inner wall of the outer shell 301. At the same time, the lower end of the screw column 301b is fixedly provided with a first conical wheel 301b-1. A second conical wheel 301c-2 is engaged on one side of the first conical wheel 301b-1, and one end of the second conical wheel 301c-2 is fixedly connected to the second I-shaped wheel 301c through a rotating column 301c-1. The rotating column 301c-1 is rotatably connected to the side plate of the outer shell 301. A second rotating shaft 303a is fixedly mounted on the output end of the second bidirectional motor 303, and a third I-shaped wheel 303a-1 is symmetrically fixed at both ends of the second rotating shaft 303a. The second rotating shaft 303a is rotatably sleeved on the side wall of the outer casing 301, and the second I-shaped wheel 301c and the third I-shaped wheel 303a-1, which are aligned vertically, are driven by a belt 305. A suction plate 302c is arrayed and fixed on the bottom surface of the material transfer plate 302. In use, the above-mentioned setup utilizes the second bidirectional motor 303 to rotate the second rotating shaft 303a, thereby achieving synchronous rotation of the two third I-beam wheels 303a-1. This, combined with the transmission of the belt 305, enables synchronous rotation of the two second I-beam wheels 301c. The rotation of the rotating column 301c-1 achieves rotation of the second conical wheel 301c-2. Due to the meshing between the second conical wheel 301c-2 and the first conical wheel 301b-1, the screw column 301b is ultimately rotated. Because of the helical engagement between the screw column 301b and the lifting plate 302a, the rotation of the screw column 301b causes the transfer plate 302 to reciprocate vertically. This, along with the suction plate 302c, adsorbs and transfers the biscuits from the feeding mechanism 200 onto the conveyor belt 101. Example 3

[0038] Reference Figure 4 , Figure 5 and Figure 6 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that in order to better and more conveniently stack and stack the biscuits and transfer them later, this embodiment is proposed.

[0039] Specifically, a support platform 202 is fixedly provided at the middle position of the inner side of the support frame 201. The support platform 202 has a placement groove 202a for placing the material plate 203a, and the holding plate 203 is stacked on the material plate 203a. The top surface of the holding plate 203 has an array of holding grooves 203c for pre-stacking and stacking biscuits. The holding plate 203 has a circumferential array of mating holes 203b along the holding grooves 203c. At least four mating holes 203b are provided in the same circumferential direction of the holding grooves 203c. The top surface of the material plate 203a has a positioning pin 203a-1 that slides through the mating hole 203b. The transfer plate 302 has a positioning hole 302b for the positioning pin 203a-1 to slide through. When using the above setup, the staff first places the stacked cookies in the holding groove 203c. Then, the staff aligns the mating hole 203b through the positioning pin 203a-1. When the positioning pin 203a-1 passes through the mating hole 203b, it can automatically adjust the position of the cookies to prevent them from being stacked unevenly. During the feeding process, the transfer plate 302 moves down, and the positioning hole 302b initially passes through the positioning pin 203a-1. In this way, the transfer plate 302 can gradually transfer the stacked cookies out. Example 4

[0040] Reference Figure 2 , Figure 9 , Figure 10 and Figure 11 This is the fourth embodiment of the present invention. This embodiment is based on any of the above embodiments. The difference is that, in order to better implement the present invention, the structure of the sandwich material conveying mechanism 400 for grouting is described in detail.

[0041] Specifically, the sandwich feeding mechanism 400 includes a discharge box 401, a feeding hopper 402 located above the discharge box 401, pusher plates 403 symmetrically arranged on both sides inside the discharge box 401, and a slurry plate 404 fitted and fixed to the bottom plate of the discharge box 401. A box cover 402a is fixed to the bottom surface of the feeding hopper 402, and the box cover 402a is fixedly connected to the top surface of the discharge box 401 by bolts. Screw rods 403a are symmetrically arranged inside the discharge box 401, and the screw rods 403a are rotatably connected to the side wall of the discharge box 401. One end of the screw rod 403a extends to the outside of the discharge box 401 and is fitted into the output end of the second drive motor 403b. The drive motor 403b is fixedly connected to the outer wall of the discharge box 401. Two screw rods 403a are screwed into two push plates 403 in a one-to-one correspondence and slide into another push plate 403, so that one screw rod 403a drives one push plate 403 to move along the axis of the screw rod 403a. The lower end of the side of the two push plates 403 that are close to each other is provided with an arc-shaped surface 403c. The arc-shaped surface 403c can temporarily collect the slurry when the push plate 403 moves. Slurry grooves 404b are arrayed on the slurry plate 404, and slurry nozzles 404a are fixed on the bottom surface of the slurry plate 404 at the slurry grooves 404b. In use, the above-mentioned setup involves adding the slurry through the feeding hopper 402 and then into the dispensing box 401. As the second drive motor 403b drives the screw rod 403a to rotate, the pusher plate 403 moves along the axis of the screw rod 403a. During the movement of the pusher plate 403, the slurry in the dispensing box 401 is pushed onto the dispensing plate 404, and under the action of gravity, some of the slurry is injected into the dispensing tank 404b. Apart from the slurry injected into the dispensing tank 404b, the excess slurry is stored below the arc-shaped surface 403c between the two pusher plates 403. As the pusher plate 403 moves back and forth, the slurry can be gradually filled into the dispensing tank 404b and finally sprayed out from the dispensing nozzle 404a and added to the biscuit.

[0042] Furthermore, a baffle plate 402b is symmetrically arranged at the lower end of the inner part of the feeding hopper 402. A rotating rod 402b-1 is fixedly sleeved in the baffle plate 402b, and both ends of the rotating rod 402b-1 are rotatably sleeved on the feeding hopper 402. One end of the rotating rod 402b-1 extends to the outside of the feeding hopper 402 and connects to the gear disk 402b-2, and the two gear disks 402b-2 mesh. The other end of one of the rotating rods 402b-1 extends to the outside of the feeding hopper 402 and is embedded in the output end of the first drive motor 402b-3, and the first drive motor 402b-3 is fixedly connected to the outer wall of the feeding hopper 402. An air inlet pipe 402a-1 is symmetrically fixed on the top surface of the box cover 402a on both sides of the feeding hopper 402, and the output end of the air inlet pipe 402a-1 is connected to the external air pump. When dealing with thick slurry, after the slurry is filled into the slurry tank 404b, the first drive motor 402b-3 drives the rotating rod 402b-1 to rotate. Through the meshing of the two gear discs 402b-2, the rotation of the rotating rod 402b-1 ultimately achieves mutual abutment between the two baffle plates 402b and the inner wall of the feeding hopper 402, thus achieving a seal between the feeding hopper 402 and the discharge box 401. At this time, gas is injected through the air inlet pipe 402a-1. Under the action of increased air pressure inside the discharge box 401, the thick slurry in the slurry tank 404b is sprayed out through the slurry nozzle 404a.

[0043] Furthermore, cylinders 401a are fixedly installed on the outer walls of the four corners of the discharge box 401, and the lower ends of the cylinders 401a are fixedly connected to the outer guard 102, so as to drive the sandwich feeding mechanism 400 to adjust its position in the vertical direction, thereby enabling effective slurry injection when producing multi-layer sandwich biscuits.

[0044] Additionally, it should be noted that components not described in detail in this article are existing technologies.
