Abstract
Description
Technical Field
[0001] This application relates to the field of dried bean curd processing technology, and more specifically, to a dried bean curd forming device. Background Technology
[0002] In the production of dried bean curd, the forming and extrusion process is a crucial step. Traditional forming and extrusion equipment connects the bean curd residue to the pressure plate via a transmission component. However, the pressure plate can cause uneven pressure distribution, resulting in uneven density of the dried bean curd and areas that are too hard or too soft, affecting the texture. Furthermore, the use of only one bottom mold frame during the extrusion and feeding process leads to significant time waste and reduced production efficiency. Therefore, we propose a dried bean curd forming device. Utility Model Content
[0003] 1. Technical problems to be solved
[0004] The purpose of this application is to provide a bean curd forming device that solves the technical problems in the background art mentioned above. This device allows for switching between an inner and outer hollow frame during processing by sliding the outer hollow frame. This enables the bean curd to be flipped and unloaded during the extrusion process, significantly improving the efficiency of bean curd forming. Furthermore, during the extrusion of bean curd residue using the pressing template and the inner hollow frame, multiple massage columns arranged in a rectangular array gently squeeze and massage the bean curd, promoting uniform distribution and tight bonding of the residue, thus improving the forming quality of the bean curd.
[0005] 2. Technical Solution
[0006] This application provides a tofu forming device, comprising: a support frame, a bottom mold shell assembly slidably mounted on the support frame, an L-shaped seat and a water receiving box fixedly mounted on the support frame, an electric cylinder fixedly mounted on the upper surface of the L-shaped seat, the piston rod of the electric cylinder moving through the L-shaped seat and fixedly connected to a pressing template, and an elastic extrusion mechanism mounted on the pressing template.
[0007] The bottom mold shell assembly includes two outer hollow frames, which are fixedly connected by a connecting mechanism. The outer hollow frames are slidably installed along the support frame, and each outer hollow frame is rotatably hinged to an inner hollow frame.
[0008] The elastic extrusion mechanism includes a motor and a sliding plate. The motor is fixedly mounted on the upper surface of the pressure plate, and two cams are fixedly mounted on the output shaft. The sliding plate is slidably sleeved on the outside of the piston rod of the electric cylinder. Multiple sliding rods are fixedly arranged in a matrix on the bottom surface of the sliding plate. The sliding rods are movably inserted into the pressure plate and are fixedly connected to a massage column. A second spring is sleeved on the sliding rod and fixedly mounted between the sliding plate and the pressure plate.
[0009] By adopting the above technical solution, the bean curd residue is placed in the inner hollow frame using a water-permeable cotton cloth. By sliding the two outer hollow frames, the inner hollow frame containing the bean curd residue moves to the bottom of the pressing template. The piston rod of the electric cylinder drives the pressing template downwards. The pressing template, in conjunction with the inner hollow frame, extrudes the bean curd residue, squeezing out the moisture that flows through the outer hollow frames and into the water collection box. The bean curd residue is thus shaped. During the extrusion process, the output of the motor drives two cams to rotate. Under the action of multiple second springs, the slide plate drives multiple sliding rods to reciprocate up and down. The tofu is gently squeezed and massaged by multiple massage columns distributed in a rectangular array, which promotes the even distribution and tight binding of the tofu residue, improving the forming quality of the tofu. Since the squeezing and water permeation process takes a certain amount of time, raw materials can be prepared and another inner hollow frame can be placed during this period. After squeezing is completed, the piston rod of the electric cylinder rises, and by sliding the outer hollow frame, another tofu residue can be squeezed and formed. The squeezed tofu can be quickly demolded by rotating and flipping the inner hollow frame. By using two inner hollow frames alternately, the forming efficiency of tofu can be greatly improved.
[0010] Optionally, the support frame has two sliding grooves, and the bottom surface of the outer hollow frame is fixed with two sliding strips, which are slidably installed in the corresponding sliding grooves.
[0011] By adopting the above technical solution, the two outer hollow frames can be slidably installed along the grooves opened in the support frame by sliding strips. By sliding the outer hollow frames horizontally, the position of the inner hollow frame can be adjusted, thereby switching the inner hollow frame for bean curd forming and processing operations.
[0012] Optionally, four connecting strips are fixedly connected between the outer hollow frames, and two of the connecting strips are fixedly connected to an F-shaped frame. A positioning rod is threaded onto the F-shaped frame, and two positioning holes are opened on the support frame. The positioning rod is inserted into either positioning hole.
[0013] By adopting the above technical solution, the outer hollow frames are fixedly connected by four connecting strips, so that they can be slidably installed together along the support frame. When any one of the outer hollow frames slides to the bottom position of the pressing template, it can be limited and inserted into the corresponding positioning hole by rotating the positioning rod, so that the two outer hollow frames are limited and fixed on the support frame.
[0014] Optionally, two angular rods are fixedly provided on both sides of the inner hollow frame, and two rectangular slots are provided on both sides of the outer hollow frame. The angular rods are elastically engaged in the corresponding rectangular slots, and a handle is fixedly provided at one end of the inner hollow frame.
[0015] By adopting the above technical solution, when the inner hollow frame rotates inside the outer hollow frame, the angular rod of the inner hollow frame is elastically engaged in the corresponding rectangular slot, thereby ensuring the stable positioning and installation of the inner hollow frame, which can stably cooperate with the pressing template to squeeze the bean curd residue.
[0016] Optionally, guide rods are fixedly provided at the four corners of the upper surface of the pressing template. The guide rods are slidably connected to the L-shaped seat. A first spring is sleeved on the guide rod and fixed between the pressing template and the L-shaped seat.
[0017] By adopting the above technical solution, when the piston rod of the electric cylinder drives the pressing plate to move, the pressing plate drives the four guide rods to slide along the L-shaped seat, so that the pressing plate can slide stably, and the first spring set in achieves a buffering effect.
[0018] Optionally, the pressing template has multiple T-shaped circular grooves arranged in a rectangular array, and the slide rod and massage column are slidably installed along the T-shaped circular grooves. The massage column is made of elastic silicone material.
[0019] By adopting the above technical solution, the slide bar and massage column are slidably installed along the T-shaped groove, and the massage column is made of elastic silicone material, so that the pressure is more evenly distributed on the bean curd residue, avoiding the situation of excessive or insufficient local pressure, so that the bean curd residue is evenly distributed and tightly combined, thereby improving the forming quality of the bean curd.
[0020] 3. Beneficial effects
[0021] One or more technical solutions provided in this application have at least the following technical effects or advantages: During the processing of the bean curd forming device, the outer hollow frame can be slid to switch to the inner hollow frame, so that the bean curd forming process of the other inner hollow frame can be completed during the bean curd extrusion process, and the bean curd turning and feeding and raw material preparation work can be completed, which greatly improves the bean curd forming and processing efficiency. During the bean curd residue extrusion process in conjunction with the pressing template and the inner hollow frame, multiple massage columns distributed in a rectangular array are used to gently squeeze and massage the bean curd, which promotes the uniform distribution and tight bonding of the bean curd residue and improves the forming quality of the bean curd.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.
[0029] Reference Figures 1 to 5 This application provides a tofu forming device, comprising: a support frame 1, a bottom mold shell assembly 6 slidably mounted on the support frame 1, an L-shaped seat 2 and a water receiving box 7 fixedly mounted on the support frame 1, an electric cylinder 3 fixedly mounted on the upper surface of the L-shaped seat 2, the piston rod of the electric cylinder 3 moving through the L-shaped seat 2 and fixedly connected to a pressure template 4, and an elastic extrusion mechanism 5 mounted on the pressure template 4.
[0030] The bottom mold shell assembly 6 includes two outer hollow frames 61, which are fixedly connected by a connecting mechanism. The outer hollow frames 61 are slidably installed along the support frame 1, and each outer hollow frame 61 is rotatably hinged to an inner hollow frame 62.
[0031] The elastic extrusion mechanism 5 includes a motor 51 and a sliding plate 53. The motor 51 is fixedly mounted on the upper surface of the pressing plate 4, and two cams 52 are fixedly mounted on the output shaft. The sliding plate 53 is slidably sleeved on the outside of the piston rod of the electric cylinder 3. Multiple sliding rods 54 are fixedly arranged in a matrix on the bottom surface of the sliding plate 53. The sliding rods 54 are movably inserted into the pressing plate 4 and are fixedly connected to a massage column 55. A second spring 541 is sleeved on the sliding rod 54 and fixedly mounted between the sliding plate 53 and the pressing plate 4. The bean curd residue is placed in the inner hollow frame 62 using a water-permeable cotton cloth. By sliding the two outer hollow frames 61, the inner hollow frame 62 containing the bean curd residue moves to the bottom of the pressing plate 4. The piston rod of the electric cylinder 3 drives the pressing plate 4 to move downward. The pressing plate 4, in conjunction with the inner hollow frame 62, extrudes the bean curd residue. The moisture in the bean curd residue is squeezed out and passes through the outer hollow frame 61. The water flows into the water collection box 7, while the bean curd residue is squeezed and shaped. During the squeezing process, the output end of the motor 51 drives two cams 52 to rotate. Under the action of multiple second springs 541, the slide plate 53 drives multiple slide rods 54 to move up and down reciprocally. This utilizes multiple massage columns 55 distributed in a rectangular array to gently squeeze and massage the bean curd, promoting the uniform distribution and tight binding of the bean curd residue and improving the shaping quality of the bean curd. Since the squeezing and water permeation process takes a certain amount of time, raw materials can be prepared and another inner hollow frame 62 can be placed during this period. After squeezing is completed, the piston rod of the electric cylinder 3 rises. By sliding the outer hollow frame 61, another bean curd residue can be squeezed and shaped. The squeezed bean curd can be quickly demolded by rotating and flipping the inner hollow frame 62. By using two inner hollow frames 62 alternately, the processing efficiency of bean curd shaping can be greatly improved.
[0032] Reference Figure 2 and Figure 4 The support frame 1 has two grooves 11. The bottom surface of the outer hollow frame 61 is fixed with two sliding strips 611. The sliding strips 611 are slidably installed in the corresponding grooves 11. The two outer hollow frames 61 can be slidably installed along the grooves 11 of the support frame 1 through the sliding strips 611. By sliding the outer hollow frame 61 horizontally, the position of the inner hollow frame 62 can be adjusted, thereby switching the inner hollow frame 62 to perform the bean curd forming and processing operation.
[0033] Reference Figure 4 and Figure 5Four connecting strips 612 are fixedly connected between the outer hollow frames 61. Two connecting strips 612 are fixedly connected to an F-shaped frame 613. A positioning rod 614 is threaded on the F-shaped frame 613. Two positioning holes 12 are opened on the support frame 1. The positioning rod 614 is inserted into either positioning hole 12. The outer hollow frames 61 are fixedly connected by the four connecting strips 612, so that they can slide together along the support frame 1. When either outer hollow frame 61 slides to the bottom position of the pressing template 4, the positioning rod 614 can be rotated to limit the insertion into the corresponding positioning hole 12, so that the two outer hollow frames 61 are limited and fixed on the support frame 1.
[0034] Reference Figure 4 and Figure 5 Two angled rods 621 are fixedly provided on both sides of the inner hollow frame 62, and two rectangular slots 615 are provided on both sides of the outer hollow frame 61. The angled rods 621 are elastically engaged in the corresponding rectangular slots 615. A handle 622 is fixedly provided at one end of the inner hollow frame 62. When the inner hollow frame 62 rotates into the outer hollow frame 61, the angled rods 621 of the inner hollow frame 62 are elastically engaged in the corresponding rectangular slots 615, thereby ensuring the stable positioning and installation of the inner hollow frame 62, which can stably cooperate with the pressing template 4 to squeeze the bean curd residue.
[0035] Reference Figure 2 and Figure 3 Guide rods 41 are fixedly installed at the four corners of the upper surface of the pressing template 4. The guide rods 41 are slidably connected to the L-shaped seat 2. A first spring 42 is sleeved on the guide rod 41 and fixed between the pressing template 4 and the L-shaped seat 2. When the piston rod of the electric cylinder 3 drives the pressing template 4 to move, the pressing template 4 drives the four guide rods 41 to slide along the L-shaped seat 2, so that the pressing template 4 can slide stably and achieve a buffering effect through the first spring 42.
[0036] Reference Figure 2 and Figure 3 The pressing template 4 has multiple T-shaped circular grooves 43 arranged in a rectangular array. The sliding rod 54 and the massage column 55 are slidably installed along the T-shaped circular grooves 43. The massage column 55 is made of elastic silicone material. The sliding rod 54 and the massage column 55 are slidably installed along the T-shaped circular grooves 43. The massage column 55 is made of elastic silicone material, which makes the pressure more evenly distributed on the bean curd residue, avoiding the situation of excessive or insufficient pressure in some areas. This makes the bean curd residue evenly distributed and tightly bound, improving the forming quality of the bean curd.
[0037] Working principle: During use, by sliding the outer hollow frame 61, an inner hollow frame 62 is positioned at the bottom of the pressing template 4. The positioning rod 614 is inserted into the corresponding positioning hole 12 to fix the outer hollow frame 61. The bean curd residue material is first placed in the inner hollow frame 62 at the bottom of the pressing template 4 using a water-permeable cotton cloth. The piston rod of the electric cylinder 3 drives the pressing template 4 to move downward. The pressing template 4, together with the inner hollow frame 62, extrudes the bean curd residue material. The water content in the bean curd residue material is squeezed out and flows through the outer hollow frame 61 into the water collection box 7. The bean curd residue material is then extruded and shaped. During the extrusion process, the output end of the motor 51 drives two cams 52 to rotate. Under the action of multiple second springs 541, the slide plate 53 is driven. Multiple sliding rods 54 move up and down in a reciprocating motion, thereby using multiple massage columns 55 distributed in a rectangular array to gently squeeze and massage the dried bean curd, promoting the uniform distribution and tight bonding of the dried bean curd residue, and improving the forming quality of the dried bean curd. Since the squeezing and water permeation process takes a certain amount of time, raw materials can be prepared and another inner hollow frame 62 can be placed during this period. After squeezing is completed, the piston rods of the two electric cylinders 3 rise and the positioning rod 614 is removed. By sliding the outer hollow frame 61, the position of the inner hollow frame 62 can be switched, and another dried bean curd residue can be squeezed and formed. The squeezed dried bean curd can be quickly demolded by rotating and flipping the inner hollow frame 62. Thus, by using the two inner hollow frames 62 alternately, the forming and processing efficiency of dried bean curd can be greatly improved.
