Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sausage casing production technology, and more specifically, it relates to a clamping assembly and a sausage casing shaping mechanism. Background Technology
[0002] Sausage casings are made by washing, chopping, acid and alkali treatment, extracting collagen fibers, extruding, drying, plasticizing, maturing, and rolling or shrinking the inner skin of animals. They are mainly used as outer casings for filling sausages and grilled sausages, and have good air permeability.
[0003] The finished sausage casings are very long and are usually shortened and segmented into "sticks," i.e., shortened sausage casing sticks. Currently, the market offers sausage casings with a threaded pattern. During the shortening process, the casing is rotated and shortened onto the shortening stick. However, due to the material of the casing, the casing tends to pile up on the shortening stick during shortening and cannot unfold along the axial direction of the stick. Therefore, a clamp is needed to hold one end of the casing. By clamping and fixing the casing to the shortening stick, and then rotating and dragging the casing, the stacked casing can be unfolded while ensuring the pattern is neat after unfolding. However, when the clamp moves to the end holding the casing, it is prone to interference with the casing processing device. Utility Model Content
[0004] The present invention provides a clamp assembly to solve the technical problems mentioned in the background section.
[0005] The technical solution adopted in this utility model is a clamping assembly for clamping the sausage casing lassoed on the lasso bar, including:
[0006] Mounting base, the mounting base having a clearance hole through which the cable rod passes;
[0007] Multiple clamps are arranged circumferentially on the mounting base. The multiple clamps can approach each other to form a first clamping space, through which a lasso rod can pass. The multiple clamps can cooperate to clamp the sausage casing onto the lasso rod.
[0008] The driving structure includes a chuck connected to a driving structure, each driving structure being disposed on the mounting base and positioned along a first direction. The driving structure drives the chuck to move along the first direction, and the first direction forms an angle greater than 30° and less than 60° with the axis of the clearance hole.
[0009] It is understandable that the drive structure is generally large in size. Therefore, in the above-mentioned chuck assembly, the drive structure is set along the first direction, and the first direction forms an angle greater than 30° and less than 60° with the axis of the clearance hole. The angle within this range can prevent the drive structure from occupying too much space in the vertical direction, and can also reduce the travel required for the drive chuck to clamp or release the casing. In the above manner, the chuck assembly can be closer to the casing processing device and clamp the end of the casing at the casing processing device through the chuck, thereby avoiding interference between the drive structure and the casing processing device.
[0010] As a preferred embodiment of the present invention, the chuck includes a clamping part and a connecting part, the clamping part is connected to the connecting part, the connecting part is arranged along a first direction and connected to the drive rod of the drive structure, the clamping part is arranged along a second direction, and the angle between the second direction and the axis of the clearance hole is smaller than the angle between the first direction and the axis of the clearance hole.

[0014] As a preferred embodiment of this utility model, a guide structure is provided between the connecting part and the mounting base.
[0015] As a preferred embodiment of the present invention, the guide structure includes a guide block and a limiting groove disposed on the connecting portion, the guide block extending along a first direction and slidably disposed within the limiting groove.

[0017] As a preferred embodiment of this utility model, each of the clamping parts is provided with a limiting member on the side near the connecting part. The limiting member is provided with a second arc-shaped groove. When the clamps approach each other, the second arc-shaped groove on each of the clamping parts cooperates to form a second clamping space. The second clamping space is coaxial with the first clamping space and has the same size as the end of the first clamping space away from the connecting part. The second clamping space is used for the lasso rod to pass through.
[0018] As a preferred embodiment of this utility model, the driving structure includes a cylinder and a driving rod connected to the cylinder.

[0028] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In some descriptions of utility models, "a plurality of" means two or more, unless otherwise explicitly specified.
[0032] This utility model provides a clamping assembly for clamping the sausage casings lassoed on the lasso rod, so that the clamping assembly can drive the sausage casings to rotate and move along the axial direction of the lasso rod in subsequent processes.
[0033] See Figure 1 and Figure 2 A chuck assembly includes a mounting base 100, a plurality of chucks 200, and a drive structure 300.
[0034] The mounting base 100 has a clearance hole 110 for the cable rod to pass through.
[0035] Multiple clamps 200 are arranged circumferentially on the mounting base 100. The multiple clamps 200 can approach each other to form a first clamping space. The first clamping space allows the lasso rod to pass through, and the multiple clamps 200 can cooperate to clamp the sausage casing onto the lasso rod.
[0036] Each chuck 200 is connected to a drive structure 300. Each drive structure 300 is disposed on the mounting base 100 and is disposed on the mounting base 100 along a first direction. The drive structure 300 drives the chuck 200 to move along the first direction. The first direction forms an angle greater than 30° and less than 60° with the axis of the clearance hole 110.
[0037] Specifically, each clamp 200, under the action of its corresponding drive structure 300, can approach each other and clamp the casing on the lasso bar that passes through the first clamping space onto the lasso bar, so as to facilitate subsequent rotation of the casing and movement along the axial direction of the lasso bar.
[0038] Each chuck 200 can move away from each other under the action of the corresponding drive structure 300, so that the chuck 200 can loosen the casing.
[0039] It is understood that the drive structure 300 is generally large in volume. Therefore, in the above-mentioned chuck assembly, the drive structure 300 is arranged along the first direction, and the first direction forms an angle greater than 30° and less than 60° with the axis of the clearance hole 110. The angle within this range can prevent the drive structure 300 from occupying too much space in the vertical direction, and can also reduce the travel required for the drive chuck 200 to clamp or release the casing. In the above manner, the chuck assembly can be closer to the casing processing device and the chuck 200 can clamp the end of the casing at the casing processing device, thereby avoiding interference between the drive structure 300 and the casing processing device.
[0040] For example, in some embodiments, the first direction may form an angle of 30°, 45° or 60° with the axis of the clearance hole 110.
[0041] See Figure 3 The chuck 200 may include a clamping part 210 and a connecting part 220. The clamping part 210 is connected to the connecting part 220. The connecting part 220 is arranged along a first direction and connected to the drive rod 330 of the drive structure 300. The clamping part 210 is arranged along a second direction, and the angle between the second direction and the axis of the clearance hole 110 is smaller than the angle between the first direction and the axis of the clearance hole 110.
[0042] It is understandable that the angle between the second direction and the axis of the clearance hole 110 is smaller than the angle between the first direction and the axis of the clearance hole 110, so that the clamping part 210 can be tilted more, which is more conducive to the clamping part 210 getting closer to the casing processing device to clamp the casing.
[0043] Furthermore, in order to facilitate the connection between the drive rod 330 of the drive structure 300 and the connecting part 220, an assembly groove 221 is provided at the end of the connecting part 220 away from the chuck 200, and an assembly block 310 is provided on the drive rod 330 of the drive structure 300, and the assembly block 310 and the assembly groove 221 are mutually engaged.
[0044] See Figure 3 In order to facilitate the formation of a first clamping space when the clamps 200 come close to each other, the inner surface of the clamping part 210 is provided with a first arc-shaped groove 211. When the clamps 200 come close to each other, the first arc-shaped groove 211 of each clamping part 210 cooperates to form the first clamping space.
[0045] In order to enable the clamping part 210 to be closer to the casing processing device to clamp the casing, the outer surface of the clamping part 210 is inclined along the third direction, and the angle between the third direction and the axis of the clearance hole 110 is smaller than the angle between the second direction and the axis of the clearance hole 110.
[0046] See Figure 2 and Figure 3 In order to improve the accuracy and stability of the movement of the chuck 200, a guide structure can also be provided between the connecting part 220 in the chuck 200 and the mounting base 100. The guide structure plays a guiding role when the drive structure 300 drives the chuck 200 to move.
[0047] Specifically, the guide structure may include a guide block 120 and a limiting groove 223 disposed on the connecting portion 220. The guide block 120 extends along a first direction and is slidably disposed within the limiting groove 223.
[0048] Furthermore, the guide blocks 120 are disposed opposite to each other on the mounting base 100, and protrusions are formed on the sides of the guide blocks 120 that are close to each other. The connecting part 220 is provided with a connecting block 222, and a limiting groove 223 is provided on the connecting block 222. The connecting block 222 is located between the guide blocks 120, and the protrusions are slidably disposed in the limiting groove 223. The above structure facilitates the sliding connection between the slider and the limiting groove 223.
[0049] See Figure 3Each clamping part 210 is provided with a limiting member 212 on the side near the connecting part 220. The limiting member 212 is provided with a second arc-shaped groove 213. When the clamps 200 approach each other, the second arc-shaped groove 213 on each clamping part 210 cooperates to form a second clamping space. The second clamping space is coaxial with the first clamping space and has the same size as the end of the first clamping space away from the connecting part 220. The second clamping space can cooperate with the first clamping space to stably pass through the lasso rod of the clamp 200.
[0050] It is understandable that since the clamping part 210 is set along the second direction, i.e., inclined, while the lasso rod is generally set along the horizontal direction, the first arc-shaped groove 211 set on the clamping part 210 is also generally inclined. That is, the first clamping space formed by the first arc-shaped groove 211 gradually increases from the end away from the driving structure 300 to the end closer to the driving structure 300. In other words, only the end of the first clamping space away from the driving structure 300 can act on the lasso rod. Therefore, the second clamping space can limit the lasso rod passing through the clamp 200 at the end away from the first clamping space and cooperate with the first clamping space, so as to stabilize the lasso rod when rotating the casing and pulling the casing.
[0051] See Figure 2 In some embodiments, the drive structure 300 may include a cylinder 320 and a drive rod 330 connected to the cylinder 320. One end of the drive rod 330 is connected to the chuck 200, and the other end of the drive rod 330 protrudes from the side of the cylinder 320 away from the chuck 200. An elastic element 340 is provided between the end of the drive rod 330 protruding from the cylinder 320 and the cylinder 320. The cylinder 320 drives the chucks 200 to move closer to each other through the drive rod 330, and the elastic element 340 drives the drive rod 330 to move the chucks 200 away from each other.
[0052] This application also provides a casing shaping mechanism, including a lasso rod, a displacement component, and a clamp 200 according to the embodiment of this application. The lasso rod passes through a clearance hole 110 into a mounting base 100. The displacement component is driven to the mounting base 100 so that the mounting base 100 can rotate and move along the axial direction of the lasso rod.
[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
