Description

Technical Field

[0001] The invention belongs to the technical field of biscuit production equipment, and in particular relates to biscuit extrusion molding equipment. Background Art

[0002] When making biscuits, flour is first mixed with auxiliary materials such as oil, sugar, and water, then pressed into a specific shape through molding equipment, and finally baked to set the shape.

[0003] For example, in Chinese utility model CN217564747U, the raw materials enter the forming cylinder and fall into the mold groove. When the forming roller rotates, the excess raw materials will be scraped off. When the mold groove filled with the raw materials rotates to the embossing mouth, the embossing mechanism embosses the raw materials in the mold groove. When the embossed mold groove rotates above the conveyor belt, the biscuits are unloaded onto the conveyor belt.

[0004] However, in the actual production process of the prior art, the raw materials will stick to the mold groove after extrusion molding, and demolding cannot be completed, affecting the overall reliability. If demolding is not possible or there are residues in the mold groove, manual shutdown and cleaning are required, resulting in low overall production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0036] See also Figures 1 to 3 As shown, the present invention is a biscuit extrusion molding device, including a frame 1, the frame 1 is connected with a molding roller 2, an embossing roller 3 and a feed hopper 4, the molding roller 2 includes a support shaft 201 and a hollow roller 202, the support shaft 201 is fixedly connected to the frame 1, the hollow roller 202 is sleeved on the outside of the support shaft 201, and is rotatably connected to the support shaft 201.

[0037] like Figures 5 to 7 As shown, a plurality of rows of forming holes 203 are evenly distributed on the circumference of the side wall of the hollow roller 202. The forming holes 203 can be arranged according to the shape of the biscuits to be produced, such as the round holes shown in the figure. Each row of forming holes 203 is arranged along the axial direction of the hollow roller 202. The forming holes 203 are in a stepped hole structure and are interspersed with pusher blocks 5. The pusher blocks 5 are stepped shaft structures that cooperate with the forming holes 203.

[0038] The pusher block 5 extends from the outside to the inside of the hollow roller 202, and is sleeved with a spring 501 and fixedly connected with a fixed block 502, which is used to push the fixed block 502 through the spring 501, so that the pusher block 5 is kept in the forming hole 203. At the same time, the step portion of the forming hole 203 is a tapered hole structure, and the pusher block 5 has a tapered surface that matches it, so that the pusher block 5 and the forming hole 203 fit more closely. The end surface of the pusher block 5 can be provided with different shapes of sinks or bosses according to the biscuits to be produced, so as to facilitate pressing the required patterns on the surface of the biscuits.

[0039] A plurality of cam plates 204 are fixedly connected to the lower side of the support shaft 201. The cam plates 204 are located inside the hollow roller 202, and the cam plates 204 correspond to the forming holes 203 in a row. During production, the forming roller 2 and the embossing roller 3 rotate synchronously and in opposite directions. The surface of the embossing roller 3 is provided with extrusion blocks corresponding to the forming holes 203. The extrusion blocks squeeze the biscuit raw materials injected into the forming holes 203 to achieve extrusion molding of the biscuits.

[0040] like Figure 5 and 6 As shown, as the forming roller 2 rotates, when the extruded biscuit raw material is in the forming hole 203 and is driven to the bottom of the support shaft 201, the fixed block 502 at the end of the pusher block 5 contacts the cam plate 204, and the forming roller 2 continues to rotate. The cam plate 204 pushes the fixed block 502, so that the pusher block 5 moves toward the outside of the forming hole 203, thereby pushing the biscuit out of the forming hole 203 and demolding it.

[0041] Among them, the fixed block 502 is connected with a roller 503 or a bull's eye bearing, which is used to cooperate with the cam plate 204 through the roller 503 or the bull's eye bearing. As shown in the figure, the roller 503 is used to utilize the rolling of the roller 503, which is beneficial to reduce the friction with the cam plate 204 and improve the reliability and stability of use.

[0042] As a preferred embodiment, Figure 2 , 4 As shown in Figures 6, the hollow roller 202 is fixedly connected to a driven wheel A205, the embossing roller 3 is fixedly connected to a driven wheel B301, and the driven wheel A205 and the driven wheel B301 are both transmission-connected to the driving mechanism for synchronously driving the forming roller 2 and the embossing roller 3 to rotate through the driving mechanism.

[0043] The driving mechanism includes two rotating shafts 101 rotatably connected to the frame 1 and a transmission shaft 102. The two rotating shafts 101 are rotatably connected to a driving wheel 103 and a transmission wheel 104. The driving wheel 103 connected to one of the rotating shafts 101 is meshed with the driven wheel A205, and the driving wheel 103 connected to the other rotating shaft 101 is meshed with the driven wheel B301.

[0044] Both ends of the transmission shaft 102 are connected with driving wheels 105 respectively meshing with two transmission wheels 104, and one of the rotating shafts 101 is connected to a driving motor 106, which drives one rotating shaft 101 to rotate, and utilizes the transmission shaft 102 to drive the other rotating shaft 101 to rotate, so that the hollow roller 202 and the embossing roller 3 are synchronously driven to rotate through one driving motor 106, thereby ensuring the synchronization of the rotation of the two.

[0045] As another preferred embodiment, Figure 2 , 10 As shown in FIG. 11 , the feed hopper 4 is connected and fixed to the frame 1 through a bracket, and is located directly above the forming roller 2, and has an injection pipe 401 corresponding to the forming holes 203 in a row.

[0046] A spiral shaft 402 corresponding to the injection tube 401 is rotatably connected in the feed hopper 4, and the lower end of the spiral shaft 402 extends into the injection tube 401. When the hollow roller 202 rotates until the upper forming hole 203 is opposite to the injection tube 401, the biscuit raw materials in the feed hopper 4 are discharged by the rotation of the spiral shaft 402, thereby injecting material into the forming hole 203.

[0047] In addition, a sleeve 403 is sleeved at the lower end of the injection tube 401, a block 404 adapted to the forming hole 203 is fixedly connected to the lower end of the sleeve 403, and the block 404 is provided with an injection hole 405. The feed hopper 4 is connected with a telescopic device 406, and the telescopic end of the telescopic device 406 is connected to the sleeve 403. Specifically, a plurality of sleeves 403 are connected and fixed by a connecting rod 407, and the telescopic end of the telescopic device 406 is connected to the connecting rod 407, so as to drive the plurality of sleeves 403 to move synchronously.

[0048] like Figure 8 and 9 As shown, during injection, the telescopic device 406 drives the connecting rod 407 to move downward, so that the multiple sleeves 403 move downward synchronously, and the blocking block 404 at the lower end of the sleeve 403 is used to block the port of the forming hole 203. At this time, the spiral shaft 402 rotates, so that the biscuit raw material enters the forming hole 203 from the injection hole 405. Since the port of the forming hole 203 is blocked, the biscuit raw material is prevented from leaking out. At the same time, it can ensure that the biscuit raw material remains relatively flat after being discharged, which is beneficial to the subsequent extrusion molding.

[0049] After the injection is completed, the telescopic device 406 drives the connecting rod 407 to move upward, so that the blocking block 404 is moved out of the forming hole 203. According to the viscosity of the biscuit raw materials, during the upward movement of the sleeve 403, the spiral shaft 402 can be controlled to reverse a certain number of circles, such as half a circle or one circle, so that a certain amount of biscuit raw materials can rise, and a certain space is reserved for the residual biscuit raw materials in the sleeve 403, which can prevent the raw materials from being squeezed out during the upward movement of the sleeve 403, which is beneficial to improving the reliability and stability of use.

[0050] In addition, the upper ends of the plurality of screw shafts 402 are connected in pairs, such as through a synchronous belt transmission connection, and one of the screw shafts 402 is connected to a motor transmission connection, so that the plurality of screw shafts 402 can be driven to rotate synchronously by one motor drive, so that each screw shaft 402 keeps rotating synchronously, which is beneficial to ensure the consistency and accuracy of the injection amount.
