Description

Technical Field

[0001] The present invention relates to the technical field of casing shrinkage production, and particularly to an automatic casing shrinkage machine for continuous casing shrinkage production. Background Technique

[0002] Casing shrinkage is a processing technology for shrinking and tightening the casing, which is usually used in the food processing industry, such as making sausages. Its purpose is to tightly wrap the casing around the filling to prevent the filling from leaking, and at the same time make the product have a better appearance and taste.

[0003] After retrieval, the Chinese invention patent with the publication number CN112825895A discloses a method and device for extruding and shrinking casings, including a frame, on which a first moving bracket and a second moving bracket are installed. A first extrusion head is installed on the first moving bracket, and a first clamping arm and a second clamping arm are installed on the second moving bracket. A first split body is provided on the first clamping arm, and a second split body is provided on the second clamping arm. The first split body and the second split body form a second extrusion head. Compared with the prior art, the Chinese invention patent with the publication number CN112825895A can make both ends of the casing shrinkage tube bear extrusion pressure at the same time and be compacted towards the middle, which can improve the density of the casing shrinkage tube and avoid disconnection.

[0004] However, in the actual use process of the above-mentioned extrusion and shrinkage casing device, the threading of the casing needs to be carried out one by one manually, with low efficiency, and the cutting link of the casing also depends on manual operation. Manual cutting cannot accurately control the cutting length, which is likely to cause the casing lengths to be inconsistent. The frequent manual intervention in the casing shrinkage process will undoubtedly increase the risk of product contamination. For this reason, we propose an automatic casing shrinkage machine for continuous casing shrinkage production that can integrate the functions of casing threading, cutting, shrinkage, and blanking. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the present invention provides an automatic casing shrinkage machine for continuous casing shrinkage production, which solves the problem that the prior art relies on manual intervention in the casing shrinkage process, thus increasing the risk of product contamination.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the present invention is realized through the following technical solutions: An automatic casing telescoping machine for continuous casing telescoping production, comprising a machine base body and a controller body installed outside the machine base body.

[0018] Preferably, the negative pressure gripper mechanism includes an electro-hydraulic push rod A, a negative pressure pump installed inside the fixed frame and connected to the controller body, and two meshing gears rotatably connected to the inside of the rear side plate. The output end of the electro-hydraulic push rod A is fixedly connected to a double-sided meshing rack meshing with the two meshing gears. Connecting gripper arms are fixedly connected to the outside of the two meshing gears. Semi-circular grippers are fixedly connected to one end of the two connecting gripper arms away from the double-sided meshing rack. Negative pressure holes are axially symmetrically opened inside the two semi-circular grippers. A T-shaped negative pressure pipe is installed at the negative pressure port of the negative pressure pump. Both ends of the T-shaped negative pressure pipe are fixedly communicated with negative pressure hoses communicated with the negative pressure holes;

[0019] By starting the electro-hydraulic push rod A to extend, the two semi-circular grippers can be opened; by starting the negative pressure pump, the negative pressure holes can adsorb and expand the port position of the casing to facilitate the insertion of the subsequent station rod.

[0025] By starting the electro-hydraulic push rod D, the U-shaped feeding arm can be made to abut against the feeding sleeve to achieve feeding. After feeding, the shrunk casing is conveyed to the next production line through the conveyor line.

[0026] In summary, the technical effects and advantages of the present invention are as follows:

[0027] 1. In the present invention: When the driving motor A is started to make the three station rods approach or move away from the stations, the hollow station rods are inserted into the inside of the flat casing through the tapered ends and the ports that are adsorbed and expanded. The negative pressure hose inside the station rods inflates the inside of the flat casing to achieve unobstructed sleeving of the station rods. When moving out, the electro-hydraulic push rod B extends to make the cutting blade cut the wrinkled casing to complete the sleeving of the casing.

[0028] 2. In the present invention: When the driving motor A is started to make the three station rods approach or move away from the stations, the station rods sleeved with the wrinkled casing enter the inside of the shrinking wheel and are compressed by the shrinking wheel to form a shrunk casing. After the shrunk casing is formed, it squeezes the pressure sensor to release the limiting effect of the shrinking wheel. When moving out, the limiting effect of the shrinking wheel is restored to complete the shrinking of the casing.

[0029] 3. In the present invention: When the driving motor A is started to make the three station rods approach or move away, the station rods sleeved outside the shrunk casing drive the feeding sleeve outside it to move above the U-shaped feeding arm. When moving out, the U-shaped feeding arm abuts against the extended feeding sleeve and pushes the shrunk casing down to the conveyor line through the feeding sleeve to complete the feeding of the casing.

[0030] 4. In the present invention, when the driving motor B is started to rotate and displace the three working position rods, the working position rod sleeved with the corrugated casing can rotate to the shrinking position to align with the casing shrinking mechanism, the working position rod sleeved with the shrunk casing can rotate to the blanking position to align with the casing blanking mechanism, and the empty sleeved working position rod can rotate to the threading position to align with the conveying and pleating mechanism. Subsequently, the processes of casing threading, shrinking, and blanking can be continued synchronously. In this way, the processes of casing threading, shrinking, and blanking can be carried out alternately.

[0031] That is, the three working position rods can synchronously and alternately carry out casing threading, shrinking, and blanking, and the continuous shrinking production of the casing can be efficiently completed without manual intervention. Description of the Drawings

[0048] Among them, the conveying and pleating mechanism 5 includes a front side plate 501 and a rear side plate 502 installed on the base body 1. Between the front side plate 501 and the rear side plate 502, there are an installation disc 503, two conveying wheels 504, and four pleating wheels 505.

[0053] Among them, the casing feeding mechanism 11 includes a conveyor line 111 installed on the top of the machine base body 1, and an electro-hydraulic push rod D112 embedded inside the machine base body 1 and connected to the controller body 2. The output end of the electro-hydraulic push rod D112 is fixedly connected with a U-shaped feeding arm 113. By starting the electro-hydraulic push rod D112, the U-shaped feeding arm 113 can be made to abut against the feeding sleeve 303 to achieve feeding. The shrunk casing 9 after feeding is conveyed to the next production line through the conveyor line 111.

[0054] The working principle of the present invention: As Figure 1 shown, at this time, among the three station rods 301, one station rod 301 is sleeved loosely, another station rod 301 is sleeved with the wrinkled casing 7, and the remaining one station rod 301 is sleeved with the shrunk casing 9. Taking Figure 1 the position states of the components in it as an example, first, by starting the drive motor A305, the three station rods 301 are made to approach and move away from the conveying and pleating mechanism 5, the negative pressure clamping hand mechanism 6, the casing cutting mechanism 8, the casing shrinking mechanism 10, and the casing feeding mechanism 11. During this process, the three station rods 301 can synchronously complete the sleeving, shrinking, and feeding of the casing.

[0055] During the process of the three station rods 301 approaching the conveying and pleating mechanism 5, the negative pressure clamping hand mechanism 6, the casing cutting mechanism 8, the casing shrinking mechanism 10, and the casing feeding mechanism 11:

[0056] The sleeved work station rod 301 drives the blanking sleeve 303 to abut against the two closed semi-circular clamping hands 606. (When the two semi-circular clamping hands 606 are closed, the negative pressure holes 607 inside them will adsorb and expand the port position of the casing), and the sleeved work station rod 301 inserts into the inside of the flat casing 4 through the tapered end and the adsorbed and expanded port, while the negative pressure hose 609 inside the work station rod 301 inflates the inside of the flat casing 4, so that the flat casing 4 expands to facilitate the unobstructed sleeve penetration of the work station rod 301;

[0057] The work station rod 301 sleeving the folded casing 7 enters the inside of the sleeve shrinking wheel 105. The folded casing 7 is compressed by the sleeve shrinking wheel 105 to form a sleeve-shrunk casing 9. After the sleeve-shrunk casing 9 is formed, it presses the pressure sensor 106, so that the pressure sensor 106 reaches the preset value, thereby causing the electro-hydraulic push rod C102 to shorten and reset once. When the electro-hydraulic push rod C102 shortens, it will drive the trapezoidal limit block 108 to disengage from the connecting block 103 through the elastic telescopic rod 107 to release the limiting effect on the sleeve shrinking wheel 105, and the sleeve shrinking wheel 105 will be pushed by the sleeve-shrunk casing 9 and compress the return spring 104;

[0058] The work station rod 301 sleeving the outside of the sleeve-shrunk casing 9 drives the blanking sleeve 303 outside it to move above the U-shaped blanking arm 113;

[0059] When the three work station rods 301 move away from the conveying and pleating mechanism 5, the negative pressure clamping hand mechanism 6, the casing cutting mechanism 8, the casing sleeve shrinking mechanism 10 and the casing blanking mechanism 11, the drive motor C508, the drive motor D509 and the drive motor E510 are started synchronously, so that the mounting disc 503 drives the casing disc 12 to rotate to evenly release the flat casing 4, the two conveying wheels 504 rotate towards each other to evenly convey the flat casing 4, and the four pleating wheels 505 push the casing along the conveying direction to form pleats;

[0060] That is, the initially sleeved work station rod 301 drives the folded casing 7 outside it to move out. Subsequently, the electro-hydraulic push rod B801 extends to make the cutting blade 803 approach the folded casing 7 and cut the folded casing 7. The cut port position of the casing still relies on the adsorption and expansion of the negative pressure holes 607;

[0061] The work station rod 301 initially sleeving the folded casing 7 drives the sleeve-shrunk casing 9 outside it to move out. The compressed return spring 104 drives the connecting block 103 to re-abut against the trapezoidal limit block 108 (the connecting block 103 relies on the inclined surface of the trapezoidal limit block 108 and the elastic telescopic rod 107 to reset) to restore the limiting effect on the sleeve shrinking wheel 105;

[0062] The station rod 301 for initially sleeving and shrinking the casing 9 drives the external blanking sleeve 303 outside it to move out. However, the blanking sleeve 303 abuts against the protruding U-shaped blanking arm 113, so that the U-shaped blanking arm 113 pushes the shrunk casing 9 down onto the conveyor line 111 through the blanking sleeve 303 to convey the shrunk casing 9 to the next production line;

[0063] In this way, the sleeving, shrinking and blanking of the casing can be completed synchronously;

[0064] Subsequently, by starting the drive motor B309, the three station rods 301 rotate and change positions, so that the station rod 301 for sleeving the wrinkled casing 7 rotates to the shrinking station and aligns with the casing shrinking mechanism 10, the station rod 301 for sleeving the shrunk casing 9 rotates to the blanking station and aligns with the casing blanking mechanism 11, and the empty station rod 301 rotates to the sleeving station and aligns with the conveying and pleating mechanism 5. Subsequently, the sleeving, shrinking and blanking of the casing can continue synchronously;

[0065] That is, the three station rods 301 can perform the sleeving, shrinking and blanking of the casing synchronously and alternately, and the continuous shrinking production of the casing can be efficiently completed without manual intervention.
