Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a device for rotary cutting of colloids. Background Technology

[0002] With the booming popularity of the milk tea and food industry, the demand for many gel products is increasing. Gel products are typically formed through drop molding and cutting. Cutting methods generally fall into two categories: transverse reciprocating cutting and rotary cutting. However, transverse reciprocating cutting equipment usually only has one cutter, resulting in low cutting efficiency. Furthermore, it primarily uses a cylinder as the drive mechanism; during operation, the back-and-forth impact of the equipment leads to high noise levels, rapid wear of parts, and a short cylinder lifespan. In rotary cutting, the difference in linear velocity between the inner and outer rings of the cutter during rotation results in a difference in the length of material cut by the inner and outer rings. This difference is related to the cutting speed; the lower the cutting speed, the greater the difference. Additionally, the molding mold needs to be immersed in a curing liquid to ensure the molding effect, and any abnormalities in the product molding process cannot be visually observed. Utility Model Content

[0003] The purpose of this invention is to provide a device for rotary cutting of colloids with low operating noise and high cutting efficiency. It can not only more intuitively observe the abnormalities of material solidification and forming, but also reduce the length difference of the material caused by the difference in linear speed between the inner and outer circles of the rotary cutter.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A device for rotary cutting of colloids includes a motor, a hopper, a spreading tray, a forming tray, a cooling tray, and a rotary cutter.

[0006] The hopper has independent material chambers and curing liquid chambers. The curing liquid chambers surround the material chambers. The rear end of the hopper has a material inlet and a curing liquid inlet, which are connected to the curing liquid chambers. The spreading tray and the molding tray are arranged sequentially from the inside to the outside of the material chambers.

[0007] The cooling plate is sealed and covered at the front end of the hopper. A cooling cavity is formed between the cooling plate and the molding plate. The curing liquid cavity is provided with a liquid outlet at the front end of the hopper. The cooling cavity is connected to the curing liquid cavity through the liquid outlet. The cooling plate is provided with a discharge hole that is connected to the cooling cavity.

[0008] The molding disc is provided with multiple extrusion nozzle groups, which are evenly spaced along the circumference of the molding disc. Each extrusion nozzle group consists of multiple extrusion nozzles arranged in a fan-shaped array. The number of extrusion nozzles is equal to the number of discharge holes and they correspond one-to-one. The extrusion nozzles pass through the discharge holes, and there is a gap between the extrusion nozzles and the hole wall of the discharge holes for the curing liquid to flow out.

[0009] The rotary cutter is located at the front end of the cooling plate, the motor is installed at the rear end of the hopper, and the output shaft of the motor passes sequentially through the hopper, the spreading plate, the forming plate, and the cooling plate, and is fixedly connected to the rotary cutter; the rotary cutter is provided with multiple cutting lines for cutting materials, the multiple cutting lines are evenly spaced along the circumference of the cooling plate, and each cutting line extends radially along the cooling plate; the number of extrusion nozzle groups is the same as the number of cutting lines;

[0010] The material spreading tray is provided with a material spreading plate, which has multiple material spreading holes. The material spreading plate divides the material cavity into an upper feeding cavity and a lower spreading cavity. The feeding cavity is connected to the feed inlet, and the spreading cavity is connected to the extrusion nozzle. The multiple spreading holes form multiple rows of spreading hole groups arranged radially on the material spreading plate. The multiple rows of spreading hole groups are evenly spaced along the circumference of the material spreading plate, and the number of rows of spreading hole groups is the same as the number of fishing lines.

[0011] As a preferred embodiment of this utility model, a cylindrical support sleeve extends from the outer periphery of the spreading plate toward the molding disc, and the front end of the support sleeve abuts against the rear end of the molding disc.

[0012] As a preferred embodiment of this utility model, the rear end of the cooling plate is provided with a protrusion, and the forming plate is provided with a mounting hole that matches the protrusion; the height of the protrusion is greater than the depth of the mounting hole.

[0013] As a preferred embodiment of this utility model, the hopper, the spreading tray, the forming tray and the cooling tray are all provided with through holes in the middle that cooperate with the output shaft of the motor.

[0014] As a preferred embodiment of this utility model, the rotary cutter includes a motor connection part, multiple horizontal connection parts, multiple vertical connection parts, and multiple fishing lines. The number of horizontal connection parts, vertical connection parts, and fishing lines is the same. The multiple horizontal connection parts are fixedly connected to the lower end of the motor connection part and are evenly spaced along the circumference of the motor connection part. The end of each horizontal connection part is fixedly connected to the vertical connection part. The fishing lines are fixedly connected between the vertical connection parts and the motor connection part.

[0015] In a preferred embodiment of this utility model, the hopper and the cooling plate are connected by a clamp.

[0016] As a preferred embodiment of this utility model, a sealing ring is provided between the hopper and the cooling plate.

[0017] The device for rotary cutting of colloids provided by this utility model has the following advantages compared with the prior art:

[0018] (1) During operation, the material passes through the feeding chamber and the spreading chamber from the feed inlet in sequence, and is extruded into strip material through the extrusion nozzle. At the same time, the curing liquid enters the curing liquid chamber from the liquid inlet, passes through the liquid outlet and cooling chamber at the front end of the hopper in sequence, and finally flows out in the gap formed between the extrusion nozzle and the wall of the discharge hole. Therefore, the curing liquid can solidify the strip material leaving the extrusion nozzle. In addition, the motor can drive the rotary cutter to rotate. The strip material is cut into granular material by the fishing line in the rotary cutter. Compared with the previous horizontal reciprocating cutting equipment driven by the cylinder, which can only be set with a single cutter, the rotary cutting form driven by the motor can be set with a single cutter or multiple cutters. The operating noise is also relatively low. When multiple cutters are set, not only can the cutting efficiency be improved, but the frequency of parts replacement can also be reduced.

[0019] (2) The motor is set so that the interval movement time and rotation speed can be set according to the cutting length of the material. When the rotation speed is large, the cutting time difference between the inner and outer rings of the rotary cutter can be reduced when the rotary cutter is rotating. In addition, the material spreading plate of the spreading plate is provided with a group of spreading holes with the same number of rows as the number of fishing lines and evenly spaced along the circumference of the spreading plate. Each extrusion nozzle group is composed of multiple extrusion nozzles arranged in a fan-shaped array. Therefore, the closer the number of extrusion nozzles is to the outer ring cutting trajectory of the rotary cutter, the more strip material is extruded. The greater the linear speed of the outer ring of the rotary cutter, the more strip material it cuts. Therefore, while improving the cutting efficiency, it can also reduce the length difference of the material caused by the difference in linear speed between the inner and outer rings of the rotary cutter.

[0020] (3) Since the hopper has independent curing liquid chamber and material chamber, there is no need to immerse the molding plate in the curing liquid. The abnormalities of material curing and molding can be observed more intuitively, thus ensuring the molding effect. Attached Figure Description

[0034] Please see Figures 1 to 8 The preferred embodiment of this utility model provides a device for rotary cutting of colloids, which includes a motor 1, a hopper 2, a spreading tray 3, a forming tray 4, a cooling tray 5, and a rotary cutter 6.

[0035] The hopper 2 is provided with an independent material chamber 21 and a curing liquid chamber 22. The curing liquid chamber 22 surrounds the material chamber 21. The rear end of the hopper 2 is provided with a material inlet 23 for material entry and a curing liquid inlet 24 for curing liquid entry. The curing liquid inlet 24 is connected to the curing liquid chamber 22. The spreading tray 3 and the molding tray 4 are arranged sequentially from the inside to the outside in the material chamber 21.

[0036] The cooling plate 5 is sealed over the front end of the hopper 2, forming a cooling cavity 7 between the cooling plate 5 and the molding plate 4. The curing liquid cavity 22 is provided with an outlet hole 25 at the front end of the hopper 2. The cooling cavity 7 is connected to the curing liquid cavity 22 through the outlet hole 25. The cooling plate 5 is provided with a discharge hole 51 that communicates with the cooling cavity 7. The molding plate 4 is provided with multiple extrusion nozzle groups 41, which are evenly spaced along the circumference of the molding plate 4. Each extrusion nozzle group 41 is composed of multiple extrusion nozzles 411 arranged in a fan-shaped array. The number of extrusion nozzles 411 and the discharge holes 51 are equal and correspond one-to-one. The extrusion nozzles 411 pass through the discharge holes 51, and there are gaps in the walls of the extrusion nozzles 411 and the discharge holes 51 for the curing liquid to flow out.

[0037] The rotary cutter 6 is located at the front end of the cooling plate 5, and the motor 1 is installed at the rear end of the hopper 2. The output shaft 11 of the motor 1 passes sequentially through the hopper 2, the spreading plate 3, the forming plate 4, and the cooling plate 5, and is fixedly connected to the rotary cutter 6. The rotary cutter 6 is provided with multiple cutting lines 64, which are evenly spaced along the circumference of the cooling plate 5, and each cutting line 64 extends radially along the cooling plate 5. The number of extrusion nozzle groups 41 is the same as the number of cutting lines 64. In this embodiment, the hopper 2, the spreading plate 3, the forming plate 4, and the cooling plate 5 are all provided with through holes 8 that cooperate with the output shaft 11 of the motor 1 in the middle.

[0038] The spreading tray 3 is provided with a spreading plate 31, which has a plurality of spreading holes 321. The spreading plate 31 divides the material cavity 21 into an upper feeding cavity 211 and a lower spreading cavity 212. The feeding cavity 211 is connected to the feeding port 23, and the spreading cavity 212 is connected to the extrusion nozzle 411. The plurality of spreading holes 321 form a plurality of radially arranged spreading hole groups 32 on the spreading plate 31. The plurality of spreading hole groups 32 are evenly spaced along the circumference of the spreading plate 31, and the number of rows of spreading hole groups 32 is the same as the number of fishing lines 64.

[0039] According to the present invention, the device for rotary cutting of colloids operates as follows: During operation, material enters from the feed inlet 23, passes sequentially through the feed chamber 211 and the spreading chamber 212, and is extruded into strips through the extrusion nozzle 411. Simultaneously, curing liquid enters from the liquid inlet 24 into the curing liquid chamber 22, passes sequentially through the liquid outlet 25 at the front end of the hopper 2 and the cooling chamber 7, and finally flows out through the gap formed between the extrusion nozzle 411 and the wall of the discharge hole 51. Therefore, the curing liquid can solidify the strips of material leaving the extrusion nozzle 411. Furthermore, the motor 1 drives the rotary cutter 6 to rotate, and the strips of material are cut into granules by the cutting line 64 in the rotary cutter 6. Compared to the conventional cylinder-driven transverse reciprocating cutting equipment, which can only be set with a single cutter, the motor-driven rotary cutting method can be set with a single or multiple cutters, and the operating noise is relatively low. When multiple cutters are set... This not only improves cutting efficiency but also reduces the frequency of parts replacement. Secondly, the motor 1 can be configured to adjust the interval movement time and rotation speed according to the cutting length of the material. When the rotation speed is high, the cutting time difference between the inner and outer rings of the rotary cutter 6 during rotation can be reduced. Furthermore, the material spreading plate 31 of the spreading disc 3 has a group of spreading holes 32 with the same number of rows as the fishing line 64, which are evenly spaced along the circumference of the spreading plate 31. Each extrusion nozzle group 41 consists of multiple extrusion nozzles 411 arranged in a fan-shaped array. Therefore, the closer the number of extrusion nozzles 411 is to the outer ring cutting trajectory of the rotary cutter 6, the more strip-shaped material is extruded. The greater the linear speed of the outer ring of the rotary cutter 6, the more strip-shaped material it cuts. Thus, while improving cutting efficiency, it can also reduce the length difference of the material caused by the difference in linear speed between the inner and outer rings of the rotary cutter 6. Furthermore, since the hopper 2 has independent curing liquid chambers 22 and material chambers 21, it is not necessary to immerse the molding disc 4 in the curing liquid, allowing for more direct observation of any abnormalities in the material curing process, thus ensuring the molding effect. It should be noted that in this embodiment, the motor 1 is preferably a servo motor.

[0040] For example, a cylindrical support sleeve 33 extends from the outer periphery of the material spreading plate 31 toward the molding disc 4. The front end of the support sleeve 33 abuts against the rear end of the molding disc 4, making assembly convenient.

[0041] For example, the rear end of the cooling plate 5 is provided with a protrusion 52, and the molding plate 4 is provided with a mounting hole 42 that matches the protrusion 52; the height of the protrusion 52 is greater than the depth of the mounting hole 42. Thus, when the protrusion 52 is assembled on the mounting hole 42, a liquid flow channel can be formed for the curing liquid to flow from the liquid outlet 25 on the front side of the hopper 2 to the discharge port on the cooling plate 5.

[0042] For example, in this embodiment, the specific structure of the rotary cutter 6 is as follows: the rotary cutter 6 includes a motor connection part 61, a plurality of horizontal connection parts 62, a plurality of vertical connection parts 63, and a plurality of fishing lines 64. The number of horizontal connection parts 62, the number of vertical connection parts 63, and the number of fishing lines 64 are the same. The plurality of horizontal connection parts 62 are fixedly connected to the lower end of the motor connection part 61 and are evenly spaced along the circumferential direction of the motor connection part 61. The end of each horizontal connection part 62 is fixedly connected to the vertical connection part 63. The fishing line 64 is fixedly connected between the vertical connection part 63 and the motor connection part 61.

[0043] For example, the hopper 2 and the cooling plate 5 are connected by a clamp (not shown in the figure), which is convenient for assembly; a sealing ring 9 is provided between the hopper 2 and the cooling plate 5, which can improve the sealing performance between the hopper 2 and the cooling plate 5.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
