[0033] As Figure 1As shown in the figure, an end trimming device for sausage casings provided by an embodiment of the present invention includes: a workbench (not shown in the figure), a sausage casing receiving rod 1 provided at one end of the workbench for loading sausage casings 5; a sausage casing pressing member 2 provided on the sausage casing receiving rod 1 for pushing the sausage casing 5 loaded on the sausage casing receiving rod 1; a trimming device provided at the other end of the workbench, the trimming device includes two trimming modules 3 symmetrically arranged on both sides of the sausage casing receiving rod 1, and a driving device 4 is provided on the trimming module 3, and the two trimming modules 3 can be driven to separate / close by the driving device 4; when the two trimming modules 3 are closed, a circular through hole is formed for receiving the end to be trimmed of the sausage casing 5 loaded on the sausage casing receiving rod 1; a spraying device 6 is provided on the trimming module 3 for spraying the end to be trimmed of the sausage casing 5.

[0034] In this embodiment, the sausage casing pressing member 2 is a T-shaped cylinder with a through hole inside, and is fixed on the workbench by a bracket. The left end of the sausage casing receiving rod 1 is arranged on the left side of the sausage casing pressing member 2 and fixed on the workbench, and the right end passes through the through hole provided in the sausage casing pressing member 2. The sausage casing receiving rod 1 can reciprocate in the through hole in the sausage casing pressing member 2 under the drive of a driving device (such as an electric device or a pneumatic device). Moreover, the sausage casing pressing member 2 can move left and right along the sausage casing receiving rod 1 under the drive of a set driving device (such as an electric device or a pneumatic device), so as to be able to push the sausage casing 5 loaded on the sausage casing receiving rod 1 to move to the right. The sausage casing receiving rod 1 moves left and right under the drive of the driving device, which is convenient for loading the sausage casing 5 onto the sausage casing receiving rod 1 before the trimming process; in addition, after the end of the sausage casing 5 is trimmed, it is convenient to unload the sausage casing 5 from the sausage casing receiving rod 1.

[0035] In this embodiment, a trimming device is provided at the right end of the workbench. The trimming device includes two trimming modules 3 respectively arranged above and below the sausage casing receiving rod 1 in a symmetrical manner. The top of the trimming module 3 located above the sausage casing receiving rod 1 and the bottom of the trimming module 3 located below the sausage casing receiving rod 1 are respectively connected with a driving device 4, such as a cylinder. The driving device 4 can control the trimming module 3 by an electric or pneumatic method, and the embodiment of the present invention does not make specific limitations in this regard. Semi-circular through holes are provided on the opposite end faces of the two trimming modules 3, so that when the two trimming modules 3 are driven to close by the driving device 4, a circular through hole is formed. This through hole can receive the end to be trimmed of the right end of the sausage casing 5 and trim it. Then, the two trimming modules 3 are driven to separate by the driving device 4 to release the right end of the sausage casing 5. For different diameters of the sausage casing 5 to be trimmed, the trimming module 3 with a corresponding aperture is selected for use.

[0036] In an alternative embodiment, the trimming module 3 and its driving device 4 located above the casing receiving rod 1 and the trimming module 3 and its driving device 4 located below the casing receiving rod 1 are respectively fixed on two fixing plates 8 which are symmetrically arranged above and below with respect to the casing receiving rod 1. The two fixing plates 8 can be opened and closed in a rotational manner with a set center of a circle and radius, thereby driving the trimming module 3 and its driving device 4 respectively fixed thereon to be opened and closed in a rotational manner, so as to obtain a larger operating space and maintenance space.

[0037] In an alternative embodiment, the trimming module 3 includes a base 31 and a trimming pressing block 32 detachably connected to the base 31. As Figure 2 and Figure 3 shown, in this embodiment, the base 31 is a rectangular frame with an open end at the bottom surface, and two side walls of the open end are turned inward to form flanges 310. The trimming pressing block 32 is a rectangular block with dimensions and shape matching those of the base 31, so that the trimming pressing block 32 can be inserted into the base 31 from the side of the base 31. And, a straight chamfer 320 is provided on the side of the trimming pressing block 32 corresponding to the flange 310 of the base 31, so that the flange 310 is buckled on the horizontal side of the straight chamfer 320, thereby making the connection between the trimming pressing block 32 and the base 31 more stable. The embodiments of the present invention do not specifically limit the shapes, structures and connection manners of the base 31 and the trimming pressing block 32, as long as a through hole for receiving the end of the casing 5 loaded on the casing receiving rod 1 can be formed when the two trimming modules 3 are closed. For different diameters of the casing 5 to be trimmed, a trimming pressing block 32 with the same outer dimensions and a semicircular through hole with a corresponding aperture is selected and installed on the base 31. In this embodiment, the trimming pressing block 32 is made of an elastic material, for example, silica gel.

[0038] Further, as Figure 4 shown, an inclined chamfer 323 (for example, the chamfer is 40°) is provided on the arc edge of the semicircular through hole on the side of the trimming pressing block 32 for receiving the casing 5, which is convenient for the end of the casing 5 to be trimmed to enter the circular through hole formed by the two closed trimming modules 3.

[0039] Further, as Figure 5 shown, the trimming pressing block 32 includes a pressing block body 321 and a pressing core 322 detachably installed in the pressing block body 321. A groove with a set depth and length is provided on the arc wall of the pressing block body 321 where the semicircular through hole is opened. The pressing core 322 is a circular arc with a width and length matching those of the groove and can be inserted into the above groove. For different diameters of the casing 5 to be trimmed, as long as a pressing core 322 with corresponding dimensions is selected and installed in the groove of the pressing block body 321. In this embodiment, the pressing block body 321 and the pressing core 322 are made of an elastic material, for example, silica gel.

[0040] In this embodiment, a spraying device 6 is provided on the trimming module 3, as Figure 1 shown. The spraying device 6 includes: a nozzle 61 provided on the trimming module 3, a liquid guide pipe 62 connected to the nozzle 61, and may further include an air pipe 63 connected to the nozzle 61. The nozzle 61 can be fixed on the driving device 4 at a position (angle and distance relative to the end of the casing 5 to be trimmed) set by a bracket.

[0041] In an alternative embodiment, as Figure 1 shown, a casing pushing rod 7 coaxial with the casing receiving rod 1 is provided on the right side of the trimming device. The casing pushing rod 7 is fixed on the workbench and can move left and right along its axis under the drive of the driving device. When loading the casing 5 onto the casing receiving rod 1 through the casing pushing rod 7, first put the casing 5 to be trimmed on the casing pushing rod 7, then move the casing pushing rod 7 to the left so that its left end is docked with the right end of the casing receiving rod 1, and then push the casing 5 from the casing pushing rod 7 onto the casing receiving rod 1 through a set loading device.

[0042] As Figure 6 shown, the embodiment of the present invention further provides a method for trimming the end of a casing, and the steps are as follows:

[0043] S1. Load the casing 5 onto the casing receiving rod 1;

[0044] The casing 5 can be directly loaded onto the casing receiving rod 1, or the casing 5 can be loaded onto the casing receiving rod 1 through the casing pushing rod 7. When loading the casing 5 through the casing pushing rod 7, first load the casing 5 onto the casing pushing rod 7, then make the left end of the casing pushing rod 7 opposite to the right end of the casing receiving rod 1, and then move the casing 5 from the casing pushing rod 7 to the casing receiving rod 1 through a set loading device.

[0045] S2. The spraying device 6 sprays the end of the casing 5 to be trimmed;

[0046] The casing 5 can be moved from the casing pushing rod 7 to a set position on the casing receiving rod 1 through a set loading device, so that the end of the casing 5 to be trimmed is within the spraying area of the spraying device 6. The liquid conveyed through the liquid guide pipe 62 is sprayed onto the end of the casing 5 to be trimmed through the nozzle 61, wetting the casing at the end to be trimmed. The sprayed liquid can be water or alcohol, and the embodiments of the present invention do not make specific limitations on this, as long as it can play a role in wetting the end of the casing. Alcohol dries quickly and is not likely to cause adhesion, but it is not suitable for halal production and is not friendly to the working environment. Spraying water has less impact on the environment. The amount of sprayed water is controlled by controlling the spraying time length, and the spraying time is generally controlled within 0.5 - 1 s. Due to different calibers and processes of the casing, the spraying time length is also different; for casings with a larger caliber, the spraying time is longer. While conveying the liquid to the nozzle 61, gas can be conveyed to the nozzle 61 through the air pipe 63, so that the liquid and gas are mixed in the nozzle 61, and finally atomized liquid is sprayed out, making the spraying area of the liquid larger and the spraying more uniform.

[0047] S3. Close the two trimming modules 3 through the driving device 4 to form a through hole for receiving the end of the casing 5 to be trimmed;

[0048] The size of the through hole formed by closing the two trimming modules 3 can be set according to the diameter of the casing 5.

[0049] S4. Push the casing 5 by the casing pressing component 2 to push the end of the casing 5 to be trimmed into the through hole and maintain for a set time;

[0050] The time length that the end of the casing 5 to be trimmed stays in the through hole is related to the production speed. The faster the production speed, the shorter the setting time. It is also related to the production cycle of each casing. Generally, it is required to maintain for more than 3 seconds, and the conventional setting is 5 - 8 seconds.

[0051] The position where the casing pressing component 2 pushes the end of the casing 5 to be trimmed into the through hole can be set as needed. After the casing 5 is pushed to the set position, the end of the casing 5 to be trimmed is squeezed by the two trimming modules 3 in the through hole, realizing the flattening of the end of the casing 5 to be trimmed.

[0052] S5. Separate the two trimming modules 3 through the driving device 4, and then unload the casing 5 from the casing receiving rod 1.

[0053] After separating the two trimming modules 3, the casing receiving rod 1 can be moved to the left. When the casing 5 moves to the left following the casing receiving rod 1 under inertia, it is blocked by the casing pressing member 2. When the casing receiving rod 1 completely exits from the casing 5, the casing 5 freely falls under the action of gravity and is collected. Alternatively, a set clamping device can be used to clamp the casing 5. When the casing receiving rod 1 completely exits from the casing 5, the clamping device clamps the casing 5 and moves it to a designated position.

[0054] The casing end trimming device provided by the present invention trims the end of the casing to be trimmed by symmetrically arranged trimming modules, ensuring the flatness of the casing end after trimming. Before trimming, the end of the casing to be trimmed is sprayed to moisten the casing, preparing for subsequent trimming. The casing end trimming method provided by the present invention can automatically trim the end of the casing without cutting the casing, reducing the loss of raw materials caused by cutting the casing and saving labor costs. At the same time, it also improves production efficiency and provides a reliable guarantee for subsequent automatic enema.
