Description

Technical Field

[0001] This utility model belongs to the field of sausage casing production technology, and more specifically, it relates to a sealing 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, a type of sausage casing with a threaded pattern is available on the market. 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 typically used to hold one end of the casing, fixing it to the shortening stick. The casing is then rotated and dragged, thus unfolding the stacked casing while ensuring the threaded pattern is neat after unfolding. Since the end of the casing held by the clamp, i.e., the tail end, does not have a threaded pattern, it needs to be tucked into the casing in the final process. Therefore, a sealing mechanism is needed to tuck the tail end of the casing into the casing. Utility Model Content

[0037] The present application provides a tail sealing mechanism for inserting the tail of a casing into the inner ring of the casing.

[0038] Referring to Figure 1 and Figure 3 , the tail sealing mechanism comprises a material receiving assembly 100 and a tail sealing assembly 200, the material receiving assembly 100 is used for receiving the casing, and the tail sealing assembly 200 is used for sealing the tail of the casing on the material receiving assembly 100.

[0039] It can be understood that in some embodiments, when the casing is processed after the last process, the casing can be pushed into the material receiving assembly 100, and the tail sealing assembly 200 can insert the tail of the casing in the material receiving assembly 100 into the inner ring of the casing, i.e. the inside of the casing.

[0040] Specifically, the material receiving assembly 100 is provided with a limiting groove 110, and the material receiving assembly 100 can be opened and closed to open or close the limiting groove 110, and when the material receiving assembly 100 opens the limiting groove 110, the casing can be loaded into the limiting groove 110.

[0041] It can be understood that before the casing is loaded into the limiting groove 110, the receiving assembly 100 can open the limiting groove 110, load the casing, and when the casing is loaded, the receiving assembly can close the limiting groove 110, so that the casing is contained in the limiting groove 110 and limited by the limiting groove 110.

[0042] The tail closing assembly 200 comprises a first tail closing piece 210 and a second tail closing piece 220. The first tail closing piece 210 and the second tail closing piece 220 are respectively located at both ends of the receiving assembly 100, and the first tail closing piece 210 and the second tail closing piece 220 can correspond to the limiting groove 110 respectively, so that the first tail closing piece 210 can extend into the inner ring from one end of the casing through the port of one end of the limiting groove 110, the second tail closing piece 220 can extend into the inner ring from the other end of the casing through the port of the other end of the limiting groove 110, and the tail of the casing is close to the side where the first tail closing piece 210 is located.

[0043] Further, referring to Figure 4 and Figure 5 , the tail closing assembly 200 further comprises a blocking piece 230, which is arranged on the side where the first tail closing piece 210 is located. The blocking piece 230 is provided with a first avoiding hole 231, the first tail closing piece 210 can extend into the inner ring of the casing through the first avoiding hole 231, and the blocking piece 230 can move towards the end of the receiving assembly 100 to stop the casing in the limiting groove 110 through the port of the limiting groove 110.

[0044] In operation, first, the receiving assembly 100 opens the limiting groove 110 to facilitate loading of the casing, and when the casing is loaded, the receiving assembly 100 closes the limiting groove 110 to limit the casing in the limiting groove 110. Then, the first tail closing piece 210 can extend or thrust the tail of the casing into the inner ring of the casing through the first avoiding hole 231 and the port of one end of the limiting groove 110 in turn. Then, the blocking piece 230 moves towards the end of the receiving assembly 100 to stop the casing in the limiting groove 110 through the port of the limiting groove 110. At this time, the first tail closing piece 210 can be retracted to the position where the end surface of the first tail closing piece 210 is flush with the end surface of the blocking piece 230. Finally, the second tail closing piece 220 extends into the inner ring of the casing from the other end of the casing through the port of the other end of the limiting groove 110, and the tail in the inner ring of the casing is pressed on the first tail closing piece 210, that is, the second tail closing piece 220 and the first tail closing piece 210 cooperate to press the tail extending into the inner ring of the casing on the port in the inner ring of the casing, thereby completing the tail closing of the casing.

[0045] It can be understood that the blocking piece 230 can stop the casing when the first tail closing piece 210 is retracted from the inner ring of the casing, so as to avoid dragging of the casing, and the blocking piece 230 can also stop the casing when the second tail closing piece 220 extends into the inner ring of the casing, so as to avoid movement of the casing.

[0046] That is, the tail sealing mechanism of the present application can realize the pressing of the tail of the casing into the port of the inner ring of the casing, and complete the automatic tail sealing of the casing.

[0047] Referring to Figure 1 and Figure 4 The tail sealing assembly 200 can further include a first tail sealing driving member 211, a second tail sealing driving member 221, and a material blocking driving member 232. The first tail sealing driving member 211 is drivingly connected with the first tail sealing member 210, the second tail sealing driving member 221 is drivingly connected with the second tail sealing member 220, and the material blocking driving member 232 is drivingly connected with the material blocking member 230. The first tail sealing driving member 211, the second tail sealing driving member 221, and the material blocking driving member 232 can be air cylinders.

[0048] Specifically, referring to Figure 3 In some embodiments, the material receiving assembly 100 can include a connecting base 120, and a first material receiving member 130a and a second material receiving member 130b oppositely arranged on the connecting base 120. The first material receiving member 130a and the second material receiving member 130b can be opened and closed relative to each other, and each of the first material receiving member 130a and the second material receiving member 130b is provided with a receiving groove on the side close to the other. When the first material receiving member 130a and the second material receiving member 130b are closed, the receiving grooves form a limiting groove 110.

[0049] It can be understood that when the first material receiving member 130a and the second material receiving member 130b are opened, the casing can be loaded into the receiving grooves on the first material receiving member 130a or the second material receiving member 130b, and then the first material receiving member 130a and the second material receiving member 130b are closed. The receiving grooves of the first material receiving member 130a and the second material receiving member 130b cooperate to limit the casing in the limiting groove 110 formed by the receiving grooves. In this way, the casing can be conveniently loaded into the limiting groove 110.

[0050] Further, in order to facilitate the opening and closing of the first material receiving member 130a and the second material receiving member 130b, the material receiving assembly 100 can further include an opening and closing driving member 140, a first gear 150a, and a second gear 150b.

[0051] The first material receiving member 130a and the second material receiving member 130b are respectively rotatably arranged on the connecting base 120. The first material receiving member 130a is connected with the first gear 150a, and the second material receiving member 130b is connected with the second gear 150b. The first gear 150a and the second gear 150b are engaged with each other. The body of the opening and closing driving member 140 is rotatably connected with the connecting base 120, and the driving rod of the opening and closing driving member 140 is rotatably connected with the first material receiving member 130a or the second material receiving member 130b. The opening and closing driving member 140 can be an air cylinder.

[0052] Specifically, taking the rotation connection between the driving rod of the opening and closing driving member 140 and the second material receiving member 130b as an example. When the driving rod of the opening and closing driving member 140 is extended, the second material receiving member 130b can rotate relative to the connecting seat 120. When the second material receiving member 130b rotates, the second gear 150b connected thereto drives the first gear 150a to rotate, and the first material receiving member 130a rotates relative to the connecting seat 120 under the action of the first gear 150a, thereby causing the first material receiving member 130a and the second material receiving member 130b to open. Similarly, when the driving rod of the opening and closing driving member 140 is retracted, the first material receiving member 130a and the second material receiving member 130b can rotate relative to the connecting seat 120 in the opposite direction, thereby causing the first material receiving member 130a and the second material receiving member 130b to close.

[0053] Referring to Figure 1 and Figure 2 , in order to facilitate the material receiving assembly 100 to receive the casing processed by the previous process and avoid interference between the tail sealing mechanism and the mechanism of the previous process, the tail sealing mechanism can further include a material receiving driving assembly 300, which is drivingly connected with the connecting seat 120, so that the accommodating groove of the material receiving assembly 100 can move between the first position and the second position. When the accommodating groove is located at the first position, the casing can be received, and when the accommodating groove is located at the second position, the first tail sealing member 210 and the second tail sealing member 220 can correspond to the limiting groove 110, respectively. That is, the material receiving assembly 100 can receive the casing at the first position, and the material receiving assembly 100 can seal the casing in the material receiving assembly 100 at the second position.

[0054] Specifically, referring to Figure 1 and Figure 3 , the tail sealing mechanism can further include a base 400, one end of the connecting seat 120 is rotationally arranged on the base 400, the body of the material receiving driving assembly 300 is rotationally connected with the base 400, and the driving rod of the material receiving driving assembly 300 is rotationally connected with the connecting seat 120. The material receiving driving assembly 300 can be a pneumatic cylinder.

[0055] It can be understood that since one end of the connecting seat 120 is rotationally connected with the base 400, when the driving rod of the material receiving driving assembly 300 is extended, the connecting seat 120 can swing, that is, the whole of the first material receiving member 130a and the second material receiving member 130b can swing between the first position and the second position, and the swinging path is a circular arc. This means that when the first material receiving member 130a and the second material receiving member 130b swing to the second position, the first material receiving member 130a and the second material receiving member 130b can be in an inclined state. In this way, after the casing is sealed, the first material receiving member 130a and the second material receiving member 130b open the limiting groove 110, and the casing can be separated from the limiting groove 110 under the action of gravity, realizing automatic discharge of the casing.

[0056] Referring to Figure 3 The receiving assembly 100 can further include a pushing member 160 arranged in the limiting groove 110 to push the casing in the limiting groove 110 to move in the direction close to the first tail closing member 210.

[0057] It can be understood that in some embodiments, when the casing of the previous process is fed into the limiting groove 110, the casing is generally located in the limiting groove 110 close to one end of the previous process. Therefore, by arranging the pushing member 160 in the limiting groove 110, the casing fed into the limiting groove 110 can be pushed in the direction close to the first tail closing member 210, so as to facilitate the first tail closing member 210 to insert the tail of the casing into the inner ring of the casing.

[0058] For example, the receiving assembly 100 can further include a mounting seat 170, a pushing driving member 180 and a rotating driving member 190. The pushing driving member 180 is arranged on the first receiving member 130a, and the first receiving member 130a is further provided with a second avoiding hole 131. The pushing driving member 180 is connected with the mounting seat 170 to drive the mounting seat 170 to move along the length direction of the first receiving member 130a. The mounting seat 170 is further provided with the rotating driving member 190. One end of the pushing member 160 is rotationally connected with the mounting seat 170 and can rotate relative to the mounting seat 170 under the action of the rotating driving member 190. The other end of the pushing member 160 can be located in the limiting groove 110 after passing through the second avoiding hole 131.

[0059] It can be understood that the rotating driving member 190 arranged on the mounting seat 170 can drive the pushing member 160 to swing relative to the mounting seat 170, that is, the end of the pushing member 160 away from the mounting seat 170 can swing away from the limiting groove 110 or move into the limiting groove 110. It can be understood that during the feeding of the casing, the rotating driving member 190 can drive the end of the pushing member 160 away from the mounting seat 170 to swing away from the limiting groove 110, so as to avoid the interference between the pushing member 160 and the casing during the feeding. When the casing is fed into the limiting groove 110, the rotating driving member 190 can drive the end of the pushing member 160 away from the mounting seat 170 to swing into the limiting groove 110, so as to facilitate the pushing member 160 to push the casing.

[0060] Specifically, for example, in an embodiment, when the previous process is located at the end of the limiting groove 110 away from the first sealing tail piece 210, before the casing is loaded, the pushing driving member 180 can drive the mounting base 170 and the pushing member 160 arranged on the mounting base 170 to move to the end of the first receiving member 130a close to the previous process. When the previous process loads the casing into the limiting groove 110, the rotating driving member 190 can drive the pushing member 160 to swing away from the end of the mounting base 170 to be located in the limiting groove 110. Then, the pushing driving member 180 drives the mounting base 170 to push the casing in the limiting groove 110 to move in the direction close to the first sealing tail piece 210, thereby moving the casing close to the side of the first sealing tail piece 210, so that the first sealing tail piece 210 can extend the tail of the casing into the inner ring of the casing.

[0061] In addition, referring to Figure 1 In some embodiments, the sealing tail mechanism can further include a cutting member assembly 500 arranged at the first position, and the cutting member assembly and the first sealing tail piece 210 are located at the same side of the receiving assembly 100, and the cutting member assembly 500 is used for cutting the tail of the casing.

[0062] Specifically, when the first position, after the previous process loads the casing into the limiting groove 110, the pushing member 160 can push the casing to the end close to the cutting member assembly 500. After the cutting member assembly 500 cuts a part of the tail of the casing, the receiving assembly 100 can move to the second position, and the sealing tail assembly 200 located at the second position can seal the tail of the casing after cutting a part of the tail.

[0063] It can be understood that in some embodiments, the tail of the casing can have various problems such as notches or cracks at the port, so that cutting a part of the tail of the casing before sealing the tail can avoid the problem part of the tail extending into the inner ring of the casing.

[0064] In addition, the cutting member assembly is arranged at the first position, and the cutting member assembly and the first sealing tail piece 210 are located at the same side of the receiving assembly 100. On the one hand, this can facilitate the cutting member assembly to cut the tail of the casing, and the sealing tail assembly 200 to seal the tail of the casing after cutting. On the other hand, this can avoid the interference between the cutting member assembly and the first sealing tail piece 210.

[0065] Referring to Figure 5 The cutting member assembly 500 can include a clamping member 510, a pulling member 520, and a cutting member 530. The clamping member 510 is used for clamping the tail of the casing. The pulling member 520 is connected with the clamping member 510, so that the clamping member 510 can move close to or away from the port of the limiting groove 110 at the second position. The cutting member 530 is arranged on the moving path of the clamping member 510, and is used for cutting the tail clamped by the clamping member 510.

[0066] Specifically, the material pulling member 520 can drive the material clamping member 510 to move to the port of the limiting groove 110 to clamp the tail of the casing, after clamping the tail of the casing, the material pulling member 520 drives the material clamping member 510 to drive the tail of the casing away from the port of the limiting groove 110, and the tail of the casing is pulled to the material cutting member 530 so that the material cutting member 530 can cut the tail. The material pulling member 520 can be a material pulling cylinder, and the material clamping member 510 can be a clamping jaw cylinder. The material cutting member 530 can include two opposing blades, one of which can be connected to a cylinder, which can drive the two blades to move closer to or away from each other, and the material pulling member 520 can drive the material clamping member 510 to move between the two blades, and when the material clamping member 510 pulls the tail of the casing between the two blades, the two blades can cooperate to cut the tail.

[0067] It can be understood that in some embodiments, when the length of the tail of the sealing tail is required, for example, to ensure that the length of the tail of each casing is consistent, the material pulling member 520 drives the material clamping member 510 to pull the tail of the casing to the material cutting member 530 for cutting, which can ensure that the length of the tail of each casing remains consistent.

[0068] Referring to Figure 5 The material cutting assembly 500 can further include a limiting member 540 and a base 550, the limiting member 540 is arranged at the second position through the base 550, an elastic member 560 is arranged between the limiting member 540 and the base 550, the limiting member 540 is used to stop the edge of the casing, and the limiting member 540 is provided with a avoiding groove 541, the material clamping member 510 clamps the tail of the casing through the avoiding groove 541.

[0069] Specifically, the limiting member 540 can limit the casing when the material pushing member 160 pushes the casing close to the port of the limiting groove 110 of the first sealing tail 210, which can prevent the material pushing member 160 from pushing the casing out of the limiting groove 110, and because the elastic member 560 is connected between the limiting member 540 and the base 550, the limiting member 540 can be buffered when stopping the edge of the casing, and the limiting member 540 can cooperate with the material pushing member 160 to limit the casing at a predetermined position, thereby ensuring that the length of the tail remaining on the casing when the material clamping member 510 clamps and pulls the tail to the material cutting member 530 for cutting is consistent. The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
