Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mold production, in particular to a mold for producing naan. Background Art
[0002] Naan comes in various sizes, with large ones typically measuring around 22cm in diameter, while smaller ones are less than 8cm. Generally speaking, the conventional process for making naan is as follows: First, flour and water are mixed to form a dough; this dough is then pressed into a round dough sheet; a mold with circular naan needles is then used to poke a number of small holes arranged in a circular pattern into the dough sheet. The purpose of these holes is to allow the air inside the dough to escape smoothly during baking, preventing localized bubbling or bulging, thus ensuring the appearance and quality of the naan.
[0003] The existing molds for producing naan have shortcomings: in the current mold production process, after the mold is formed using the template, there are obvious problems in the demolding process. When performing the demolding operation, the traditional method is to turn the mold upside down, hoping that the naan will fall off naturally under the action of gravity. However, when the flour used is too sticky, the adhesion between the dough and the inner wall of the mold is significantly enhanced. When the mold is turned upside down, the naan is difficult to pour out smoothly, which will greatly extend the demolding time and reduce production efficiency. Utility Model Content
[0004] In order to solve the problems raised in the above background technology, the utility model provides a mold for producing naan, comprising a bottom plate and pusher structures located on both sides of the top surface of the bottom plate, and a demoulding structure located above the bottom plate;
[0005] The demoulding structure includes an L-shaped plate and a cylinder fixedly connected to the bottom of the L-shaped plate, and a limit sleeve fixedly installed at the axis center of the top of the base plate. The inner wall of the limit sleeve and the inner wall of the base plate are both provided with circular grooves, and a buffer spring is fixedly connected to the inner wall of the circular groove. The top of the buffer spring is installed with a lower template.
[0006] Preferably, the output end of the cylinder is fixedly connected to a connecting ring, and two return springs are fixedly installed on the bottom of the connecting ring.
[0007] Preferably, an upper template is installed at the bottom of the connecting ring and in the middle of the two return springs, and the upper template is located directly above the lower template.
[0008] Preferably, the pushing structure includes two slide rails installed on both sides of the top of the bottom plate and a push plate slidably connected to the inner walls of the slide rails.
[0009] Preferably, a protruding block for pulling is provided on the top of the push plate and the push plate and the lower template are located in the same horizontal plane.
[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0011] The utility model adopts the design of the pushing structure and the demoulding structure, so that when making naan, the prepared dough is accurately placed just above the lower mold, and then the cylinder is started to drive the lower mold to move downward. As the lower mold gradually contacts the dough and continues to move downward, the buffer spring begins to deform, and the deformation of the buffer spring drives the lower mold plate to move downward accordingly. At the same time, the upper mold plate corresponding to the lower mold is also deformed due to the extrusion of the dough and the downward movement of the lower mold. Under the joint extrusion of the upper and lower mold plates, the dough is shaped into the shape of naan. Shape, when the naan is formed, the cylinder begins to retract, and the lower template rebounds quickly under the elastic force of the buffer spring, generating an upward thrust, which bounces the naan up to a certain height. At this time, the push plate in the pushing structure plays a role, and pushes the push plate toward the naan through a mechanical or pneumatic power source. With the help of the contact force between the push plate and the naan, the naan is pushed out of the mold area smoothly, thereby efficiently realizing rapid demoulding, greatly reducing the demoulding difficulties caused by factors such as flour stickiness, improving production efficiency, and ensuring the molding quality and integrity of the naan.

[0017] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0018] like Figures 1 to 4 As shown, the utility model provides a mold for producing naan, comprising a bottom plate 1, a pusher structure 2 located on both sides of the top surface of the bottom plate 1, and a demoulding structure 3 located above the bottom plate 1;
[0019] The demolding structure 3 includes an L-shaped plate 31 and a cylinder 32 fixedly connected to the bottom of the L-shaped plate 31, and a limit sleeve 33 fixedly installed at the top axis of the base plate 1. The inner wall of the limit sleeve 33 and the inner wall of the base plate 1 are both provided with circular grooves, and a buffer spring 34 is fixedly connected to the inner wall of the circular groove. The top of the buffer spring 34 is installed with a lower template 35.
[0020] The above scheme is adopted: through the design of the pushing structure 2 and the demoulding structure 3, when making naan, the prepared dough is accurately placed directly above the lower mold, and then the cylinder 32 is started to drive the lower mold to move downward. As the lower mold gradually contacts the dough and continues to move downward, the buffer spring 34 begins to deform, and the deformation of the buffer spring 34 drives the lower mold plate 35 to move downward. At the same time, the upper mold plate 38 corresponding to the lower mold is squeezed by the dough and the downward movement of the lower mold, causing the return spring 37 to also be deformed. Under the joint squeezing action of the upper and lower mold plates 35, the dough is shaped into naan. The shape of the cake. After the naan is formed, the cylinder 32 begins to retract. At this time, the lower template 35 rebounds quickly under the elastic force of the buffer spring 34, generating an upward thrust, which bounces the naan up to a certain height. At this time, the push plate 22 in the pushing structure 2 plays a role, and pushes the push plate 22 to move toward the naan through a mechanical or pneumatic power source. With the help of the contact force between the push plate 22 and the naan, the naan is pushed out of the mold area smoothly, thereby efficiently realizing rapid demoulding, greatly reducing the demoulding difficulties caused by factors such as flour stickiness, improving production efficiency, and ensuring the molding quality and integrity of the naan.
[0021] like Figures 1 to 4 As shown, the output end of the cylinder 32 is fixedly connected to a connecting ring 36, and two return springs 37 are fixedly installed at the bottom of the connecting ring 36. An upper template 38 is installed at the bottom of the connecting ring 36 and in the middle of the two return springs 37. The upper template 38 is located directly above the lower template 35.
[0022] The above solution is adopted: the return spring 37 has a specific elastic coefficient and stroke range, which plays a key role in the entire process of naan forming and demolding. When the cylinder 32 pushes the connecting ring 36 downward, the return spring 37 will be compressed as the connecting ring 36 moves downward, storing elastic potential energy so that the energy can be released in the subsequent process to prompt the upper template 38 to reset. The shape and size of the template are adapted to the lower template, and the two together constitute the forming space of the naan.
[0023] like Figures 1 to 4As shown, the pushing structure 2 includes two slide rails 21 installed on both sides of the top of the base plate 1 and a push plate 22 slidably connected to the inner wall of the slide rails 21. A protruding block for pulling is provided on the top of the push plate 22 and the push plate 22 and the lower template 35 are located in the same horizontal plane.
[0024] With this solution, once the naan is lifted to a certain height on the lower template 35, the push plate 22 can precisely contact the naan and apply a horizontal thrust, allowing the naan to smoothly separate from the lower template 35 in the horizontal direction. This avoids problems such as jamming and breakage of the naan caused by height discrepancies between the push plate 22 and the lower template 35.
[0025] The working principle of this utility model:
[0026] First, place the dough on top of the lower mold. At this time, the lower mold is in the initial position. Then start the cylinder 32. The output end of the cylinder 32 drives the upper mold 38 and the lower mold to move downward together through the connecting ring 36. When the lower mold contacts the dough and continues to move downward, the buffer spring 34 deforms and drives the lower mold 35 to move downward. At the same time, the upper mold 38 deforms the return spring 37. The upper and lower molds 35 squeeze the dough and gradually shape it into a naan. After forming, the cylinder 32 retracts, and the lower mold 35 moves upward under the action of the buffer spring 34. The naan will rebound to a certain height. At this time, the push plate 22 located in the same horizontal plane and slidably connected to the slide rail 21, with the help of the protruding block on its top, is manually slid along the slide rail 21 toward the naan. The push plate 22 accurately contacts the lifted naan and applies a stable horizontal thrust, so that the naan can be smoothly separated from the lower template 35 along the horizontal direction, effectively avoiding the problem of push jam and naan breakage due to uneven force, and successfully completing the demoulding process. After that, the next round of naan production cycle can be carried out.
