Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of automatic unloading devices, and more specifically, to an automatic unloading device for a plastic casing shrinking machine. Background Technology

[0002] Plastic casings are food packaging casings made from high molecular polymers. They are characterized by uniform specifications, stable performance, and ease of use, and are widely used in the processing of meat products such as sausages and hams. To facilitate subsequent storage, transportation, and processing, the produced casings are usually folded and compressed. During the folding and compression process, workers insert the casing through a sleeve and place the sleeve between two rollers. The rotation of the two rollers causes the casing on the sleeve to move backward, thereby achieving the folding of the casing.

[0003] After the sausage casings are folded, the workers scrape them off the sleeve and collect them. Removing the folded casings from the sleeve is usually done manually. If the sleeve is short, the worker needs to remove the casing after shrinking one or two sections, which is cumbersome due to frequent repetitions. If the sleeve is long, and there are many folded casings on it, although multiple folded casings can be removed at once, the resistance when sliding a large number of casings down the sleeve may be greater than when removing one or two, making it more laborious. Therefore, we propose an automatic unloading device for the plastic sausage casing folding machine. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide an automatic unloading device for a plastic sausage casing folding machine, which solves the technical problem in the prior art where it is cumbersome or laborious for workers to slide multiple sausage casings down into the sleeve after the casings have been folded.

[0005] According to one aspect, at least one embodiment of this disclosure provides an automatic unloading device for a plastic casing folding machine, including a mounting plate, casing push rods, a push assembly, and a scraper ring. The mounting plate is mounted on the worktable of the casing folding machine, and a through groove is provided on the side of the mounting plate. Sliding grooves are provided at the top and bottom of the through groove. The casing push rods are disposed in both through grooves of the mounting plate. The casing push rods are slidably mounted in the sliding grooves of the through grooves via sliders, and the two casing push rods are placed vertically opposite each other. The push assembly is disposed on the side of the mounting plate, and the two casing push rods are disposed on the push assembly. The push assembly drives the casing push rods to move. The scraper ring is mounted on the two casing push rods via an upper sliding rod and a lower sliding rod, and the upper sliding rod and the lower sliding rod are detachably mounted on the two casing push rods via an upper fixing assembly and a lower fixing assembly, respectively.

[0006] Furthermore, the upper fixing assembly includes a fixing frame, an upper fixing rod one, and an upper fixing rod two. The fixing frame is fixedly installed on one of the casing push rods. Fixing holes are provided on both sides of the fixing frame and on the side of the upper sliding rod. The upper fixing rod one is detachably installed in the fixing hole. The side of the casing push rod is provided with a fixing hole. The upper fixing rod two is detachably installed in the fixing holes of the casing push rod and the upper sliding rod.

[0007] Furthermore, the lower fixing assembly includes a stabilizing ring and a lower fixing rod. The stabilizing ring is fixedly installed on another casing pusher rod, and the lower sliding rod slides through the stabilizing ring. Fixing holes are provided on the sides of both the casing pusher rod and the lower sliding rod, and the lower fixing rod is detachably installed in the fixing holes.

[0008] Furthermore, the feeding assembly includes a support cover, a reciprocating screw, a motor, and a sliding assembly. Two support covers are fixedly installed on the side of the mounting plate. The reciprocating screw is rotatably installed in one of the support covers, and a matching crescent-shaped slider is installed on the reciprocating screw. The crescent-shaped slider is fixedly connected to the side of one of the casing feeding rods through a connecting bracket. The motor is installed on one of the support covers, and the output end of the motor is coaxially connected to the reciprocating screw. The sliding assembly is disposed in the other support cover.

[0009] Furthermore, the sliding assembly includes a limiting rod, a sliding block, and a connecting rod. The limiting rod is fixedly installed inside another support cover, the sliding block is slidably installed on the limiting rod, and the sliding block is fixedly connected to the side of another casing pusher rod through a connecting frame. The connecting rod is fixedly installed between the two connecting frames.

[0010] In order to clamp the sleeve, the scraper ring is further configured as a semi-circle, and the two scraper rings are located in the same vertical position.

[0011] In order to fix the scraper ring after clamping it with the sleeve, further, when the two scraper rings are in contact, the upper fixing rod is inserted into the fixing hole of the upper sliding rod and one of the casing push rods, and the lower fixing rod is inserted into the fixing hole of the lower sliding rod and the other casing push rod.

[0012] In order to adjust the gripping of the sleeve by the scraper ring, the upper sliding rod and the lower sliding rod are respectively slidably mounted on the two casing push rods.

[0013] The beneficial effects of the embodiments disclosed herein are as follows:

[0014] In this disclosure, after the casing is folded, the mounting plate can be placed on the side of the sleeve. Then, the upper fixing component and the lower fixing component move the two scraping rings respectively to clamp the sleeve. After clamping, the scraping rings are moved to the outermost end of the sleeve. At this time, there are several casings folded on the sleeve. Finally, the casing scraping rod and scraping rings are moved by the pushing component to scrape all the casings off the sleeve and collect them.

[0015] In summary, this device, through the cooperation of the mounting plate, casing pusher, pusher assembly, and scraper ring, can scrape off all the folded casings from the sleeve without manual operation, making it convenient and labor-saving. Attached Figure Description

[0029] like Figures 1-5 As shown, an automatic unloading device for a plastic casing folding machine according to an embodiment of this disclosure is illustrated. The device includes a mounting plate 1, casing pushers 2, a pusher assembly, and a scraper ring 3. The mounting plate 1 is mounted on the worktable of the casing folding machine. A through groove is provided on the side of the mounting plate 1. Sliding grooves are provided at the top and bottom of the through groove. A casing pusher 2 is installed in each of the two through grooves of the mounting plate 1. The casing pushers 2 are slidably mounted in the sliding grooves of the through grooves via sliders. The two casing pushers 2 are placed vertically opposite each other. The pusher assembly is located on the side of the mounting plate 1, and the two casing pushers 2 are mounted on the pusher assembly. The pusher assembly drives the casing pushers 2 to move. The scraper ring 3 is mounted on the two casing pushers 2 via an upper sliding rod 4 and a lower sliding rod 5. The upper sliding rod 4 and the lower sliding rod 5 are detachably mounted on the two casing pushers 2 via an upper fixing assembly and a lower fixing assembly, respectively.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, after the casings are folded (the casing folding of the casing shrinking machine is existing technology and will not be described in detail here), the mounting plate 1 is placed and bolted to the table of the folding machine. The two scraping rings 3 are clamped to the sleeve by the upper fixing component and the lower fixing component. The upper fixing component includes a fixing frame 6, an upper fixing rod 1 7 and an upper fixing rod 2 8. The fixing frame 6 is fixedly installed on one of the casing push rods 2. Fixing holes are opened on both sides of the fixing frame 6 and the side of the upper sliding rod 4. The upper fixing rod 1 7 is detachably installed in the fixing hole. The side of the casing push rod 2 is fixedly installed. The upper fixing rod 2 8 is detachably installed in the fixing holes of the casing push rod 2 and the upper sliding rod 4. The lower fixing component includes a stabilizing ring 9 and a lower fixing rod 10. The stabilizing ring 9 is fixedly installed on the other casing push rod 2. The lower sliding rod 5 slides through the stabilizing ring 9. Fixing holes are opened on the side of the casing push rod 2 and the lower sliding rod 5. The lower fixing rod 10 is detachably installed in the fixing hole.

[0031] Specifically, when placing the sleeve between the two scraper rings 3, the upper fixing rod 7 and the lower fixing rod 10 can be removed first. This is because the upper sliding rod 4 and the lower sliding rod 5 are respectively slidably mounted on the two casing pusher rods 2. Since the scraper rings 3 are semi-circular and both scraper rings 3 are located in the same vertical position, the upper sliding rod 4 can be used to move one of the scraper rings 3 upwards. Then, the upper fixing rod 7 is inserted into the fixing holes of the fixing bracket 6 and the upper sliding rod 4 to fix it. Next, the lower sliding rod 5 slides up and down on the other casing pusher rod 2, creating a distance between the two scraper rings 3, thus placing the sleeve between the two scraper rings 3. Then, the sliding rod... The upper sliding rod 4 moves the upper scraper ring 3 downward to fit the sleeve. Then, the lower sliding rod 5 moves the lower scraper ring 3 upward to fit the sleeve. When the two scraper rings 3 fit together, the upper fixing rod 8 is inserted into the fixing hole of the upper sliding rod 4 and one of the casing push rods 2, and the lower fixing rod 10 is inserted into the fixing hole of the lower sliding rod 5 and the other casing push rod 2. Then, the upper fixing rod 8 and the lower fixing rod 10 are respectively inserted into the fixing holes of the two casing push rods 2, the upper sliding rod 4, and the lower sliding rod 5, thereby fixing the scraper ring 3 in place. It should be noted that the scraper ring 3 is compatible with the sleeve of the casing folding machine and can fit and clamp the sleeve.

[0032] like Figure 4 As shown, after clamping, the two scraping rings 3 are moved to the rear end of the sleeve by the pushing assembly. Then, multiple sections of sausage casing are folded sequentially on the sleeve until they completely occupy the sleeve. Then, the pushing assembly drives the scraping rings 3 to scrape the folded sausage casing off the sleeve. The pushing assembly includes a support cover 11, a reciprocating screw 12, a motor 14, and a sliding assembly. Two support covers 11 are fixedly installed on the side of the mounting plate 1. The reciprocating screw 12 is rotatably installed in one of the support covers 11, and a matching crescent-shaped slider 13 is installed on the reciprocating screw 12. 13 is fixedly connected to the side of one of the casing push rods 2 via a connecting frame 18. A motor 14 is mounted on one of the support covers 11, and the output end of the motor 14 is coaxially connected to the reciprocating screw 12. A sliding assembly is set inside another support cover 11. The sliding assembly includes a limiting rod 15, a sliding block 16, and a connecting rod 17. The limiting rod 15 is fixedly mounted inside another support cover 11. The sliding block 16 is slidably mounted on the limiting rod 15. The sliding block 16 is fixedly connected to the side of another casing push rod 2 via a connecting frame 18. A connecting rod 17 is fixedly installed between the two connecting frames 18.

[0033] Specifically, the motor 14 is started, and the output end of the motor 14 drives the reciprocating screw 12 to rotate inside the support cover 11, thereby driving the crescent slider 13 to move above the reciprocating screw 12. Under the drive of the connecting frame 18, one of the casing push rods 2 moves. And under the connection and drive of the connecting frame 18 of the connecting rod 17 and the sliding block 16, the sliding block 16 drives the other casing push rod 2 to move synchronously on the limit rod 15, thereby driving the two scraping rings 3 to move synchronously on the sleeve, scraping the casing off the sleeve.

[0034] Working principle: When unloading the folded sausage casings, firstly, when placing the sleeve between the two scraping rings 3, remove the upper fixing rod 7 and the lower fixing rod 10. Then, move one of the scraping rings 3 upward with the upper sliding rod 4. Insert the upper fixing rod 7 into the fixing holes of the fixing frame 6 and the upper sliding rod 4 to fix it. Next, slide the lower sliding rod 5 up and down on the other sausage casing pusher 2 to create a distance between the two scraping rings 3, thus placing the sleeve between the two scraping rings 3. Then, slide the upper sliding rod 4 to move the upper scraping ring 3 down to fit the sleeve. Then, slide the lower sliding rod 5 to move the lower scraping ring 3 up to fit the sleeve. Insert the upper fixing rod 8 and the lower fixing rod 10 into the fixing holes of the two sausage casing pushers 2, the upper sliding rod 4, and the lower sliding rod 5 respectively, thus fixing the scraping rings 3 in place.

[0035] After placement, start motor 14. The output end of motor 14 drives reciprocating screw 12 to rotate inside support cover 11, thereby driving crescent slider 13 to move above reciprocating screw 12. Under the drive of connecting frame 18, one of the casing push rods 2 moves. And under the connection and drive of connecting frame 18 of connecting rod 17 and sliding block 16, sliding block 16 drives the other casing push rod 2 to move synchronously on sliding rod. First, move scraper ring 3 to the rear end of sleeve. After the casing is folded, move scraper ring 3 in the opposite direction. The scraping of scraper ring 3 scrapes the casing off the sleeve.

[0036] It should be added that the casing shrinking machine is installed in the factory building, and its power supply and control are operated by the control system in the factory building. The power supply of motor 14 can also be connected to the power supply system or power source in the factory building.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
