Description

Technical Field

[0001] The utility model relates to the field of automatic cutting and packaging of tofu, in particular to a lifting mechanism for cutting and packaging tofu in water. Background Technique

[0002] Tofu is a delicious and nutritious food, and people often eat tofu in daily life. In the process of automatic production, the produced tofu is often cut into pieces and then sealed in a box for easy transportation and sale.

[0003] At present, due to the fragility of tofu itself, there is no integrated cutting and boxing machine on the market, and the processing efficiency is not high. If not careful during boxing, the tofu may be broken, affecting the integrity and beauty of the tofu in the box. For example, a kind of automatic cutting machine for tofu in water disclosed in the patent No. CN117445045A produced by our company. The formed tofu and the fork assembly are rotated 180 degrees upward as a whole around the long rotating shaft under the action of the rotating lifting mechanism. After the rotation is completed, the tofu box with the opening facing upward and the tofu block inside are placed on the box scraping mechanism. The box scraping mechanism transports the two to the conveyor, and the conveyor transports the two to the next processing location.

[0004] This structure can achieve zero contact and zero pollution in the whole cutting and packaging process, and solve the problem that the tofu is easy to break during boxing. However, during the cutting of the formed tofu in this process, it is outside the water, and the temperature outside the water is higher than that in the water. At this time, the texture of the tofu is relatively soft and it is easy to break during cutting. Therefore, our company has specially designed a lifting mechanism to solve the technical problem that the original structure cannot cut the formed tofu in water. Content of the Utility Model

[0005] The utility model provides a lifting mechanism for cutting and packaging tofu in water, aiming to further streamline the tofu cutting and packaging structure and ensure the intact form of the tofu during cutting.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A lifting mechanism for cutting and packaging tofu in water, comprising: a fixed frame, on which a climbing frame is installed, and a climbing trolley sliding on the climbing frame. The climbing frame includes a straight section and an ascending section, and the included angle between the straight section and the ascending section is an obtuse angle; the straight section includes two spaced straight plates, and sliding grooves are opened in both straight plates;

[0008] Large pulleys matching the two sliding grooves are arranged on both sides of the climbing trolley, and small pulleys rolling on the ascending section are arranged. A small fixed shaft is arranged between the two small pulleys on both sides. One side of the climbing trolley close to the large pulley is connected with a cross scissors frame, and a plurality of tofu compartments are fixedly arranged at intervals on the cross scissors frame; a longitudinal cutting knife corresponding to each tofu compartment is arranged in front of each tofu compartment.

[0009] Preferably, the ascending section includes two ascending plates arranged at intervals. One end of the two ascending plates is provided with a driving shaft, the driving shaft passes through one of the ascending plates and is connected to a rotating motor, and the other end is provided with a driven shaft. The driving shaft and the driven shaft are connected by a chain drive, and the small fixed shaft of the climbing trolley is fixedly connected to the chain.

[0010] Preferably, a tofu cutting board is provided on the front side of the tofu compartment, and longitudinal cutting knives corresponding to each tofu compartment are provided on the tofu cutting board.

[0011] Preferably, when the climbing trolley climbs onto the ascending plate, the scissors frame is pulled open, and the heights of multiple tofu compartments are lifted and evenly spaced.

[0012] Preferably, the fixed frame is provided with a plurality of adjusting feet.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: It can realize the cutting of tofu into blocks in water. The temperature in water is low, the texture of tofu is relatively hard, and it is not easy to break during cutting, which can better ensure the shape of tofu.

Detailed Embodiment

[0017] Next, a preferred embodiment of the present utility model will be described in conjunction with the drawings, and the technical solutions in a preferred embodiment of the present utility model will be clearly and completely described.

[0018] As Figures 1 to 2 shown: A lifting mechanism for cutting and loading tofu in water includes: a fixed frame 1, a climbing frame 2 installed on the fixed frame 1, and a climbing trolley 3 sliding on the climbing frame 2. The climbing frame 2 includes a straight section 21 and an ascending section 22, and the included angle between the straight section 21 and the ascending section 22 is an obtuse angle; the straight section 21 includes two straight plates 211 arranged at intervals, and slideways 212 are opened in both of the two straight plates 211;

[0019] On both sides of the climbing trolley 3, there are large pulleys 31 matching the two sliding tracks 212, and small pulleys 32 rolling on the ascending section 22. Between the two small pulleys 32 on both sides, there is a small fixed shaft 321. On one side of the climbing trolley 3 close to the large pulley 31, there is a cross scissors frame 33 connected. On the cross scissors frame 33, a plurality of tofu compartments 34 are fixedly arranged at intervals. In front of each tofu compartment 34, there is a corresponding longitudinal cutter 342.

[0020] Through the above design of the present utility model, the manipulator pushes the strip-shaped tofu into the tofu compartment 34. In the pushing path, it will pass through the tofu longitudinal cutter 342 to cut the strip-shaped tofu into small block specifications. The present utility model can drive the climbing trolley 3 to climb towards the ascending plate 23 by using a manipulator or other power mechanisms. The climbing trolley 3 drives the cross scissors frame 33 to pull apart a row of small block-specification tofus and lift them to a set distance and height. Then, the manipulator pushes the block-shaped tofu to the next processing place. This structure can realize the in-water block cutting of tofu. The water temperature is low, the texture of tofu is relatively hard, and it is not easy to break during cutting, which can better ensure the shape of tofu.

[0021] Specifically, the ascending section 22 includes two ascending plates 23 arranged at intervals. At one end of the two ascending plates 23, there is a driving shaft. The driving shaft passes through one of the ascending plates 23 and is connected with a rotating motor 24. At the other end, there is a driven shaft. The driving shaft and the driven shaft are connected by a chain 25 in transmission. The small fixed shaft 321 of the climbing trolley 3 is fixedly connected with the chain 25.

[0022] Through the above design of the present utility model, when the rotating motor 24 is driven, the rotating motor 24 drives the chain 25 in transmission, thereby driving the climbing trolley 3 fixedly connected with the chain 25 to climb towards the ascending section 22. This driving method ensures that the small block-specification tofus are pulled apart and improves the stability, so as to facilitate the subsequent box-packing process.

[0023] Specifically, a tofu cutting board 341 is arranged on the front side of the tofu compartment 34. On the tofu cutting board 341, there are longitudinal cutters 342 corresponding to each tofu compartment 34.

[0024] Through the above design of the present utility model, when the strip-shaped tofu is pushed onto the tofu cutting board 341 by the manipulator, it is cut into a row of small block tofus by the longitudinal cutter 342 on the tofu cutting board 341, completing the block cutting of the strip-shaped tofu.

[0025] Specifically, when the climbing trolley 3 climbs towards the ascending plate 23, the cross scissors frame 33 is pulled apart, and a plurality of tofu compartments 34 are lifted in height and are evenly spaced.

[0026] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
