Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a fixed-length shearing process for sausage casing gummies and its rotary shearing device. Background Technology

[0002] Sausage-cased gummies are a type of traditional candy made by filling sausage casings or similar membrane materials with gelling agents such as gelatin and starch. They are usually long and thin strips and need to be cut into single candy bodies of a fixed length. Fixed-length cutting is a crucial post-processing step in the production of sausage-cased gummies, as the cutting quality directly affects the regularity, appearance, and production efficiency of the product.

[0003] A search revealed patent document CN119141619A, which discloses a sausage casing soft candy cutting machine, comprising: a processing area set inside the machine housing and a flip-type cover covering the processing area; the processing area includes a horizontally set base and a vertically set mounting plate on the side of the base; a conveying assembly including a conveying channel for conveying materials along the long side of the processing area, the material conveying direction of the conveying channel being parallel to the mounting plate; a control system for determining kinks in the material and sending cutting instructions to the cutting system according to the kink position; the cutting system including an upper cutter head and a lower cutter head that perform relative lifting actions, the upper cutter head and the lower cutter head being set near the discharge end of the conveying channel, and cutting the material in the conveying channel in response to the cutting instructions; and a feeding and discharging system fixed on the side wall of the machine housing and connected to the feeding and discharging ends of the conveying channel, respectively.

[0004] Based on the above search and existing technology, it was found that most existing devices use a straight-blade shearing method to cut sausage casings and gummies. Although this achieves a certain degree of mechanization, its working principle is mostly intermittent, which often has the following drawbacks:

[0005] First, intermittent motion limits the further improvement of production cycle time, making it unable to match the output speed of modern high-speed extrusion filling equipment, resulting in low production efficiency;

[0006] Secondly, in the existing rotary shearing device, the sausage casing candy tends to stick to the blade during the shearing process, making it difficult to remove the material and affecting subsequent cutting.

[0007] Based on this, the present invention provides a fixed-length cutting process for sausage casing gummies and a rotary cutter cutting device thereof. Summary of the Invention

A first conveyor belt is mounted between the first roller and the second roller, and a second conveyor belt is mounted on the pair of drive rollers.

[0014] The unloading assembly is mounted on the base and mounting bracket.

[0015] The material removal assembly includes a blower fixedly installed inside the base, an air outlet pipe fixedly installed on one side of the blower, and a T-shaped pipe fixedly installed at the end of the air outlet pipe.

[0016] Preferably, two pairs of support plates are fixedly installed inside the mounting base, and a support shaft is rotatably installed between the two pairs of support plates. Pulleys are fixedly installed on both the support shaft and the transmission shaft, and a transmission toothed belt is sleeved between a pair of pulleys.

[0017] Preferably, mounting cylinders are fixedly installed at both ends of the support shaft, and multiple hobs are fixedly installed at equal intervals on the mounting cylinders. A protective cover is fixedly installed on one side of each hob, and multiple strip-shaped through holes are opened at equal intervals on the mounting cylinders.

[0018] Preferably, a drive roller is fixedly connected between the pair of drive rollers, and a drive belt is sleeved between the drive roller and the roller. A pair of drive gears are fixedly installed on both the drive roller and the support shaft, and the drive gears on the drive roller and the support shaft mesh with each other.

[0019] Preferably, the mounting base has two pairs of rotating shafts 1 and 2 symmetrically rotatably mounted inside. A lateral conveyor belt is sleeved between adjacent rotating shafts 1 and 2. A support shell is fixedly mounted on the bottom of the mounting base. The bottoms of multiple rotating shafts 2 are rotatably mounted inside the bottom of the support shell. A servo motor 2 is fixedly mounted on the base. One of the rotating shafts 2 is fixedly connected to the output shaft of the servo motor 2. A transmission gear 1 is fixedly mounted on each rotating shaft 2. A transmission belt 2 is sleeved between two rotating shafts 2.

[0020] Preferably, air supply pipes are fixedly installed on both sides of the three-way pipe, an air jet is rotatably installed inside the mounting cylinder, the other end of the air supply pipe is fixedly installed inside the air jet, multiple air outlets are fixedly installed at equal intervals on the air supply pipe, and an air outlet hole is opened on the air jet.

[0021] Preferably, a fixing plate is fixedly installed on one side of a pair of support plates, a storage tank is fixedly installed on the fixing plate, a micro pump is fixedly installed on the storage tank, a nozzle is fixedly installed between each pair of support plates, and a suction pipe and a discharge pipe are fixedly connected between the micro pump, the storage tank, and the nozzle, respectively.

[0022] Preferably, a storage block is fixedly installed at the bottom of the nozzle, a sliding groove is provided inside the storage block, a baffle is slidably installed inside the sliding groove, a through groove adapted to the baffle is provided on the inner side wall of the nozzle, a side air pipe is fixedly connected between the air supply pipe and the storage block, and the end of the side air pipe is connected to the sliding groove.

[0023] A process for cutting sausage casings to a fixed length includes the following steps;

[0024] Step 1: First, the long strip of sausage-shaped gummies, which have been fully cooled and shaped in a cooling or settling room, are sent out by conveyor belt 2, and the side conveyor belts on both sides are used to straighten the sausage-shaped gummies.

[0025] Step 2: Adjust the rotation speed of the mounting cylinder according to the required cutting length. The sausage casing candy moves forward with the conveyor belt, and its movement speed is mechanically synchronized with the rotation speed of the mounting cylinder and the roller. Start the servo motor, blower and micro pump to ensure that the cutting component, conveying component and unloading component are working properly.

[0026] Step 3: When the sausage-cased gummy reaches the cutting point, the roller cutter rotates to the cutting position to complete one cut. Since the speed and spacing are fixed, it can ensure that each gummy is the same length.

[0027] Step 4: After cutting, connect the strip-shaped through hole on the mounting cylinder to the air outlet. Under the airflow generated by the blower, the cut sausage casing candies will be blown off to prevent them from sticking to the roller cutter. After the air outlet and the strip-shaped through hole are misaligned, the air pressure inside the side air pipe increases, which can move the baffle. The micro pump sprays the release agent onto the surface of the roller cutter through the nozzle, making it easier to demold when cutting the sausage casing candies next time.

[0028] Step 5: Finally, the cut individual sausage-shaped gummies will fall onto conveyor belt 1, achieving fixed-length cutting of the sausage-shaped gummies.

[0029] This invention provides an improved process for cutting sausage casings into fixed lengths and a rotary cutter-type cutting device, which has the following improvements and advantages compared with the prior art:

[0030] Firstly, this invention uses a blower, air supply pipe, and air outlet to blow off the cut sausage casing gummies, preventing them from adhering to the roller and affecting the next cut. Furthermore, a protective cover is provided on the roller to prevent excessive airflow from blowing the sausage casing gummies into the device, thus avoiding waste. In addition, a micro-pump is used to evenly spray the release agent from the storage tank onto the roller through a nozzle, facilitating subsequent demolding of the sausage casing gummies and further improving demolding efficiency.

[0031] Secondly, this invention can reasonably control the working state of the demolding component according to the rotation speed of the servo motor. When the rotation speed is high, the air pressure inside the side air pipe is low, and the slide plate is in the lower position, which facilitates increasing the amount of demolding agent sprayed. Because the rotation speed is high, it is necessary to increase the amount of demolding agent sprayed on the roller to ensure the normal demolding of the sausage casing candy. When the rotation speed is low, the pressure of the air jet will be high, which will result in a higher air pressure inside the side air pipe, which will push the slide plate up appropriately, thereby adjusting the size of the nozzle outlet. This allows for flexible adjustment and avoids excessive or insufficient demolding agent spraying, which may affect the normal shearing operation. Attached Figure Description

[0044] This invention provides an improved process for cutting sausage casings to a fixed length and a rotary cutter-type cutting device. The technical solution of this invention is as follows:

[0045] Example 1

[0046] like Figures 1 to 8 As shown, this embodiment of the invention provides a fixed-length rotary cutter shearing device for sausage casing gummies, including a mounting base 1, a base 2 fixedly mounted on the bottom of the mounting base 1, a pair of observation covers 3 rotatably mounted on the top of the mounting base 1 via a movable shaft, and two pairs of side support plates 6 symmetrically fixedly mounted on the bottom of the mounting base 1. It also includes a cutting component, a conveying component, and a material unloading component. The structural design of this device ensures the stability and ease of operation of the device. The observation covers 3 facilitate real-time monitoring of the internal shearing process, and the side support plates 6 effectively prevent the gummies from shifting during the conveying process.

[0047] The cutting component is located inside the mounting base 1. As the core component, the cutting component is responsible for precisely cutting the sausage casing gummy.

[0048] The cutting assembly includes a servo motor 4 fixedly installed inside the base 2. The output shaft of the servo motor 4 is fixedly mounted with a transmission shaft 5. The other end of the transmission shaft 5 is rotatably connected to the base 2 through a connecting plate. The servo motor 4 provides power and drives the cutting assembly to operate through the transmission shaft 5, ensuring the continuity and stability of the cutting action.

[0049] The conveying assembly is installed on the side support plate 6.

[0050] The conveying assembly includes a first roller 7 and a second roller 10 rotatably mounted inside each pair of side support plates 6, and a pair of drive rollers 12. A first conveyor belt 8 is sleeved between the first roller 7 and the second roller 10, and a second conveyor belt 13 is sleeved on the pair of drive rollers 12. The conveying assembly achieves continuous feeding and output of sausage-shelled gummies through the coordinated operation of multiple sets of conveyor belts. The first conveyor belt 8 is used to collect the cut gummies, and the second conveyor belt 13 is used to transport the uncut gummies.

[0051] The unloading assembly is mounted on the base 2 and the mounting base 1.

[0052] The descrambling assembly includes a blower 31 fixedly installed inside the base 2. An air outlet pipe 32 is fixedly installed on one side of the blower 31, and a three-way pipe 33 is fixedly installed at the end of the air outlet pipe 32. The blower 31 generates airflow, which is distributed through the air outlet pipe 32 and the three-way pipe 33 to achieve efficient descrambling.

[0053] Furthermore, two pairs of support plates 21 are fixedly installed inside the mounting base 1. A support shaft 22 is rotatably installed between the two pairs of support plates 21. Pulleys 25 are fixedly installed on both the support shaft 22 and the transmission shaft 5. A transmission toothed belt 26 is sleeved between a pair of pulleys 25. The support plates 21 and the support shaft 22 provide a stable support structure. The transmission toothed belt 26 ensures that the power is smoothly transmitted from the transmission shaft 5 to the support shaft 22, ensuring shearing synchronization.

[0054] Furthermore, mounting cylinders 27 are fixedly installed at both ends of the support shaft 22. Multiple roller cutters 28 are fixedly installed on the mounting cylinders 27 at equal intervals. A protective cover 29 is fixedly installed on one side of each roller cutter 28. Multiple strip-shaped through holes 30 are opened at equal intervals on the mounting cylinders 27. The mounting cylinders 27 and the roller cutters 28 constitute a rotary shearing unit. The protective cover 29 prevents the soft candy from splashing, and the strip-shaped through holes 30 facilitate airflow and assist in unloading.

[0055] Furthermore, a drive roller 11 is fixedly connected between a pair of drive rollers 12. A drive belt 9 is sleeved between the drive roller 11 and the roller 7. A pair of drive gears 23 are fixedly installed on both the drive roller 11 and the support shaft 22. The drive gears 23 on the drive roller 11 and the support shaft 22 mesh with each other. The drive roller 11 transmits power through the drive belt 9 and the drive gears 23 to ensure that the conveying and shearing speeds are synchronized and to improve the shearing accuracy.

[0056] Furthermore, two pairs of rotating shafts 14 and 15 are symmetrically mounted inside the mounting base 1. A lateral conveyor belt 16 is fitted between adjacent rotating shafts 14 and 15. A support shell 20 is fixedly mounted at the bottom of the mounting base 1. The bottoms of multiple rotating shafts 15 are rotatably mounted inside the support shell 20. A servo motor 17 is fixedly mounted on the base 2. One of the rotating shafts 15 is fixedly connected to the output shaft of the servo motor 17. A transmission gear 18 is fixedly mounted on each rotating shaft 15. A transmission belt 19 is fitted between two rotating shafts 15. The lateral conveyor belt 16 straightens the sausage casing candy to ensure that the candy is straight before cutting. The servo motor 17 drives the rotating shafts 15, and multi-axis synchronous rotation is achieved through the transmission gear 18 and the transmission belt 19 to improve the straightening effect.

[0057] Furthermore, air supply pipes 34 are fixedly installed on both sides of the three-way pipe 33, and a jet tube 24 is rotatably installed inside the mounting cylinder 27. The other end of the air supply pipe 34 is fixedly installed inside the jet tube 24. Multiple air outlets 45 are fixedly installed at equal intervals on the air supply pipe 34. An air outlet 46 is opened on the jet tube 24. The air supply pipe 34 and the air outlet 45 guide the airflow to the shear point. The jet tube 24 rotates synchronously with the mounting cylinder 27 to ensure that the airflow blows the candy at the right time. The air outlet 46 enhances the uniformity of airflow distribution.

[0058] Furthermore, a fixing plate 35 is fixedly installed on one side of a pair of support plates 21. A storage tank 36 is fixedly installed on the fixing plate 35. A micro pump 37 is fixedly installed on the storage tank 36. A nozzle 41 is fixedly installed between each pair of support plates 21. A suction pipe 38 and a discharge pipe 39 are fixedly connected between the micro pump 37, the storage tank 36, and the nozzle 41, respectively. The storage tank 36 stores the release agent. The micro pump 37 precisely controls the amount of release agent used and sprays it evenly onto the surface of the roller cutter 28 through the nozzle 41 to reduce adhesion.

[0059] Furthermore, a storage block 42 is fixedly installed at the bottom of the nozzle 41. A sliding groove 44 is provided inside the storage block 42, and a baffle 43 is slidably installed inside the sliding groove 44. A through groove adapted to the baffle 43 is provided on the inner side wall of the nozzle 41. A side air pipe 40 is fixedly connected between the air supply pipe 34 and the storage block 42. The end of the side air pipe 40 is connected to the sliding groove 44. The storage block 42 and the baffle 43 constitute an adjustable nozzle 41. The side air pipe 40 controls the position of the baffle 43 according to the change of air pressure, automatically adjusts the opening size of the nozzle 41, and realizes adaptive control of the amount of release agent.

[0060] Example 2

[0061] A process for cutting sausage casings to a fixed length includes the following steps;

[0062] Step 1: First, the long strip of sausage-shaped soft candy, which has been fully cooled and shaped in a cooling or settling room, is sent out by conveyor belt 13, and the side conveyor belts 16 set on both sides are used to straighten the sausage-shaped soft candy.

[0063] Step 2: Adjust the rotation speed of the mounting cylinder 27 according to the required cutting length. The sausage casing candy moves forward with the conveyor belt, and its movement speed is mechanically synchronized with the rotation speed of the mounting cylinder 27 and the roller 28. Start the servo motor 4, blower 31 and micro pump 37 to ensure that the cutting component, conveying component and unloading component work normally.

[0064] Step 3: When the sausage casing gummy reaches the cutting point, the roller 28 rotates to the cutting position to complete one cut. Since the speed and spacing are fixed, it can ensure that each gummy is the same length.

[0065] Step 4: After cutting, the strip-shaped through hole 30 on the mounting cylinder 27 is connected to the air outlet 45. Under the airflow generated by the blower 31, the cut sausage casing candy is blown off to avoid sticking to the roller cutter 28. After the air outlet 45 and the strip-shaped through hole 30 are misaligned, the air pressure inside the side air pipe 40 increases, which can move the baffle 43. The micro pump 37 sprays the release agent onto the surface of the roller cutter 28 through the nozzle 41, which is convenient for demolding when cutting the sausage casing candy next time.

[0066] Step 5: Finally, the cut individual sausage-shaped gummies will fall onto conveyor belt 8, achieving fixed-length cutting of the sausage-shaped gummies.

[0067] The specific working principle is as follows: After the device is started, servo motor 4 begins to work, driving transmission shaft 5 to rotate through its output shaft. Transmission shaft 5 transmits power to support shaft 22 through pulley 25 and transmission belt 26. Support shaft 22 drives mounting cylinders 27 at both ends and multiple rollers 28 fixed at equal intervals on mounting cylinders 27 to rotate together, forming a continuous rotary shearing motion. At the same time, the conveying assembly starts to work. Servo motor 17 drives rotating shaft 15, which drives all lateral conveyor belts 16 to run synchronously through transmission gear 18 and transmission belt 19, straightening the incoming sausage casing candy and ensuring that it enters the shearing zone in a straight state. The key synchronization link is that drive roller 11 is linked to roller 7 through transmission belt 9. At the same time, drive roller 11 and transmission gear 23 installed on support shaft 22 mesh with each other. This achieves mechanical hard synchronization between the linear speed of conveyor belt 13 conveying the candy and the tangential speed of the rollers 28 rotating. By adjusting the speed of servo motor 4, the length of the cut gummy candy can be precisely controlled. The straightened, long strips of sausage-shaped gummy candy are continuously fed into the shearing zone by conveyor belt 13. Since its forward speed is strictly synchronized with the rotation speed of the roller 28, when a specific position of the gummy candy reaches the shearing point, one of the rollers 28 will rotate to that position and complete the shearing action using its cutting edge and the support structure at the bottom. Because the roller 28 rotates continuously and is synchronized with the movement of the gummy candy, the shearing process is continuous and impact-free, avoiding the squeezing deformation of the candy and equipment vibration caused by the intermittent shearing of traditional straight blades. This ensures that each gummy candy is of consistent length and the cut is flat. After shearing, the cut gummy candy may adhere to the roller 28 due to the characteristics of the candy. At this time, the unloading component starts to work. The airflow generated by the blower 31 is transported through the air outlet pipe 32, the three-way pipe 33 and the air delivery pipe 34 to the air jet 24 rotating inside the mounting cylinder 27. The air outlets 45, evenly spaced on the air supply pipe 34, periodically align with the strip-shaped through holes 30 on the mounting cylinder 27. At the moment of alignment, high-pressure airflow passes through the strip-shaped through holes 30 and blows directly onto the candy adhering to the roller cutter 28, instantly removing it and completing the automatic unloading process. The protective cover 29 constrains the airflow and splashed candy, preventing it from scattering into the device and causing contamination or waste, ensuring the finished product accurately falls onto the conveyor belt 8 below for collection and output. Furthermore, to prevent the candy from adhering during subsequent shearing, the device is equipped with a release agent spraying system. The higher the device's rotational speed and shearing frequency, the higher the alignment frequency between the strip-shaped through holes 30 and the air outlets 45, resulting in a shorter time of high pressure within the side air pipe 40, a relatively lower height for the baffle 43, a smaller opening for the nozzle 41, and a smaller amount of release agent sprayed. Conversely, at lower speeds, the high-pressure period is longer, the baffle 43 is pushed higher, the nozzle opening is larger, and the amount of release agent sprayed increases. This design can automatically match the appropriate amount of release agent according to the production cycle, avoiding waste or shortage.
