Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pre-cooked meal packaging, and particularly relates to a continuous filling and sealing device for emulsified pre-cooked minced meat. BACKGROUND

[0002] As a kind of pre-cooked meat material, emulsified pre-cooked minced meat is widely used in pre-cooked half cost and finished product processing. When packaging such pre-cooked products as emulsified pre-cooked minced meat, the pre-cooked minced meat needs to be introduced into a filling bag by filling and sealed. The sealing carrier includes a self-standing bag and other square bag bodies, which are made of plastic material. Due to factory processing and electrostatic effect, the two sides of the bag body are easily adsorbed. Therefore, a series of operations such as clamping the opening of the bag body need to be performed during the filling process, so as to realize continuous filling and sealing packaging processing of the emulsified pre-cooked minced meat.

[0003] A pre-cooked minced meat product filling device is disclosed in Chinese Patent No. CN223001745U, which includes a tray on which a self-standing bag is placed. The bottom of the tray is provided with a pneumatic cylinder, and the piston rod of the pneumatic cylinder is fixedly connected with the tray. The pneumatic cylinder moves back and forth intermittently, driving the tray to move up and down, thereby driving the bottom and / or lower half of the self-standing bag to impact and shake up and down, and accelerating the flow of pre-cooked minced meat to the bottom of the self-standing bag. Therefore, a larger filling flow can be used to improve the filling efficiency, and the problem of pre-cooked minced meat overflowing from the opening of the self-sealing bag can be avoided.

[0004] For the above and existing related technologies, the inventors believe that the following defects often exist: the device mainly clamps the upper part of the bag body, and the bottom area of the general bag body is easily adsorbed due to static electricity, so that the material contacts and adheres to the inner wall of the bag body. The pre-cooked minced meat, as a general fluid, slows down the filling rate of the pre-cooked minced meat due to the adhesion effect. Although the device is provided with a pneumatic cylinder to blow air into the bag body, the bag body is open, and the blown air is quickly discharged. The high-speed airflow can cause self-attraction between the inner walls, which can accelerate the adhesion and adsorption of the bottom of the bag body, so that rapid filling can easily cause overflow, and there is room for improvement. SUMMARY

DETAILED DESCRIPTION

[0029] It is easy to understand that, according to the technical solution of the present application, those skilled in the art can propose various structural modes and implementation modes that can be replaced with each other without changing the essential spirit of the present application. Therefore, the following detailed description and the accompanying drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the whole or as the limitation or restriction of the technical solution of the present application.

[0030] Example 1: Reference Figures 1-6As shown, the present application provides a technical scheme: an emulsified pre-prepared meat emulsion continuous filling and sealing device, comprising a cabinet 1, a conveying device 2 is arranged at the bottom end in the cabinet 1, a bag unfolding device 3 is arranged at the center in the cabinet 1, a filling device 4 is arranged at the top of the cabinet 1 above the bag unfolding device 3, a heat sealing machine 6 is arranged at the top of the cabinet 1 near the discharge port, a position sensor C10 is installed at the bottom of the heat sealing machine 6 near the discharge port of the cabinet 1, a control cabinet 5 is arranged outside the cabinet 1, the bag unfolding device 3 comprises a U-shaped plate 31 fixed inside the cabinet 1, two electric telescopic rods 32 are installed on both sides of the inside of the U-shaped plate 31, movable plates 33 are fixed at one end of the electric telescopic rods 32, telescopic guide rods 35 are fixed at the upper and lower ends of the outside of the movable plates 33, one end of the telescopic guide rods 35 is connected with the inner wall of the U-shaped plate 31, limiting holes 36 are arranged in parallel on the movable plates 33, a bag sticking mechanism 34 is arranged outside the movable plates 33, the bag sticking mechanism 34 comprises a limiting roller A341 arranged on one side outside the movable plate 33, the limiting roller A341 is near the discharge port of the cabinet 1, a tape roller 343 is sleeved on the limiting roller A341, a limiting roller B342 is arranged at the other end outside the movable plate 33, a winding roller 344 is sleeved on the limiting roller B342, a tape body 345 is connected between the winding roller 344 and the tape roller 343, the tape body 345 penetrates the two limiting holes 36 in turn, the adhesive surface of the tape body 345 faces the other movable plate 33, clamping grooves 3411 are evenly arranged at the bottom end of the limiting roller A341, the clamping grooves 3411 are arranged in a ring shape, a friction plate 3413 is fixed outside the supporting plate below the clamping grooves 3411, a clamping block 3412 is fixed at the position where the top end of the friction plate 3413 abuts against the clamping grooves 3411, the clamping grooves 3411 and the clamping block 3412 are clamped and connected, a supporting mechanism 7 is connected at the bottom of the left and right movable plates 33, a position sensor A8 is arranged on the side of the movable plate 33 near the inlet of the cabinet 1.

[0031] The adhesion of the adhesive tape body 345 can make the filling bag adhere to the two sides of the bag body and expand outward when the filling bag is located between the two movable plates 33, thereby effectively preventing the mutual attraction of the positions below the bag body due to static electricity, making the entire filling bag inside present a cylindrical filling channel, ensuring that the adhesion of the prefabricated meat paste to the inner wall of the bag is reduced during filling, promoting the rapid filling of the prefabricated meat paste, and avoiding the risk of overflow of the prefabricated meat paste. At the same time, the support mechanism 7 is used to form a stable support platform for the bottom of the filling bag after it is expanded, to increase the area of the bottom of the bag during filling, thereby reducing the accumulation height of the prefabricated meat paste in the bag during filling, further preventing the overflow of the prefabricated meat paste, improving the filling quality, and using the ratchet assembly 3421, the clamping groove 3411, and the clamping block 3412 to limit the position of the adhesive tape roller 343 and the winding roller 344, prevent the adhesive tape body 345 from being randomly removed from the adhesion position during the expansion and removal of the filling bag, ensure the stability of the bag expansion and removal, and cooperate with the servo motor 3422 to automatically feed and wind the adhesive tape body 345, and automatically update the adhesion part of the adhesive tape body 345.

[0032] Referring to Figure 5 As shown in the figure, the bottom end of the limiting roller B342 is provided with a ratchet assembly 3421 outside, the bottom of the servo motor 3422 is installed outside the bottom of the movable plate 33, the output end of the servo motor 3422 is connected with the bottom of the ratchet assembly 3421, the limiting roller A341 is composed of an angular column and a circular bottom disc, the bottom ends of the limiting roller A341 and the limiting roller B342 are connected with the outer side of the movable plate 33 through a support plate, the limiting roller A341 and the limiting roller B342 have the same structure, and the inner walls of the adhesive tape roller 343 and the winding roller 344 are provided with grooves for abutting and limiting the edges outside the limiting roller A341 or the limiting roller B342.

[0033] The structure of the limiting roller A341 allows the adhesive tape roller 343 and the winding roller 344 to be quickly assembled by the top-down insertion method, which is convenient for timely replacement and compatible with existing transparent tape structures.

[0034] Referring to Figure 6 As shown in the figure, the support mechanism 7 includes a lifting disc 71, the top end of the lifting disc 71 is embedded with a weighing sensor 76, one side of the bottom end of the lifting disc 71 close to the movable plate 33 is provided with a group of U-shaped rods 72, the bottom of the movable plate 33 is fixed with a vertical plate 74, the vertical plate 74 is provided with a special-shaped hole 75, the inside of the special-shaped hole 75 is penetrated by a connecting roller 73, and the inner end of the connecting roller 73 is fixedly connected with one end of the U-shaped rod 72.

[0035] With the action of the supporting mechanism 7, when the middle part of the filling bag is unfolded to both sides, the bottom of the bag body forms an unfolded plane due to the pulling of both sides, and the position is raised, and then the guiding action of the special-shaped hole 75 is used to make the U-shaped rod 72 drive the lifting disc 71 to lift to realize the effective supporting action on the bottom of the filling bag, and cooperate with the weighing sensor 76 to make the weighing sensor 76 detect the gravity signal, and then the automatic filling action of the upper filling device 4 can be started, and through the detection of the total gravity of the filling, the filling amount can be dynamically adjusted. When the filling bag moves out, due to the disappearance of the gravity signal, the servo motor 3422 can be controlled to start to realize the automatic updating of the adhesive area of the adhesive tape main body 345. The control process based on the gravity detection action of the weighing sensor 76 is smooth and orderly, and the filling amount can be adjusted in real time.

[0036] Referring to Figure 2 , Figure 6 , the lifting disc 71 is located above the inner bottom of the U-shaped plate 31, the special-shaped hole 75 is composed of a section of inclined guide hole and straight guide hole, and when the left and right movable plates 33 approach each other, the height of the lifting disc 71 first decreases and then remains unchanged.

[0037] The structural characteristics of the special-shaped hole 75 are used to facilitate the dynamic guidance of the lifting of the lifting disc 71, avoid the large lifting height of the lifting disc 71, prevent the bag body from moving around during filling, ensure the accuracy of the detection of the weighing sensor 76, and realize the cooperation between the movement of the movable plate 33 and the movement of the lifting disc 71. Reduce the use of electrical components, improve the compactness of the structure, and reduce the space occupation.

[0038] Working principle: when the filling bag enters the position of the U-shaped plate 31, it is first detected by the in-place sensor A8 that the bag body enters, so as to control the control cabinet 5 to control the electric telescopic rod 32 to extend to a certain length and reset. When the electric telescopic rod 32 is extended, the left and right movable plates 33 approach each other and press the middle part of the filling bag, so that the adhesive surface of the adhesive tape main body 345 is attached to the two sides of the bag body. When the electric telescopic rod 32 is shortened and reset, the left and right movable plates 33 are unfolded and drive the filling bag to unfold. Because the adhesive length of the adhesive tape main body 345 is large and always connected with the bag body, the filling bag is effectively prevented from being electrostatically attached left and right during filling, which is beneficial to the smoothness of the pre-prepared meat paste injection, improves the filling rate and uniformity, and at the same time, the movable plate 33 moves to both sides, so that the vertical plate 74 moves synchronously, the connecting roller 73 moves from the straight guide hole of the special-shaped hole 75 to the inclined guide hole, and the lifting disc 71 is lifted in height, thereby supporting the bottom of the filling bag body. At this time, the weighing sensor 76 weighs the bag body, and the weighing signal is transmitted to the control cabinet 5, so that the control cabinet 5 controls the filling device 4 to start filling until the weight of the weighing sensor 76 reaches the preset value and the filling is completed.

[0039] When the filled bag moves horizontally to the side of the discharge opening of the cabinet 1 and leaves the top of the weighing sensor 76, the filled bag and the tape body 345 are pulled horizontally, and the side of the tape body 345 close to the winding roller 344 is the force direction. Since the bottom of the limiting roller B342 where the winding roller 344 is located is provided with a ratchet assembly 3421, the winding roller 344 is prevented from being pulled to rotate, thereby enabling the filled bag and the tape body 345 to be separated smoothly. When the filled bag completely leaves the top of the weighing sensor 76, the gravity signal disappears, thereby enabling the control cabinet 5 to control the servo motor 3422 to rotate, so that the winding roller 344 winds the tape body 345 by a certain length, thereby enabling the tape roller 343 to rotate synchronously and release the tape body 345 by a certain length, that is, to update the tape body 345 at the sticking position.

[0040] Embodiment 2: Refer to Figure 2 、 Figure 7 、 Figure 8 Based on the first embodiment, the reciprocating conveying mechanism 22 is used to realize automatic feeding, filling and discharging of the filling tape, and the two are synchronized to realize the continuity of the filling and sealing operation.

[0041] Refer to Figure 2 The conveying device 2 comprises a double-row roller conveyor 21, a reciprocating conveying mechanism 22 and a conveying belt 23 arranged in sequence. The conveying belt 23 is located below the heat sealing machine 6, and one end of the conveying belt 23 penetrates the discharge opening of the cabinet 1. The double-row roller conveyor 21 penetrates the feeding opening of the cabinet 1, and the top end of the reciprocating conveying mechanism 22 is lower than the bottom end of the heat sealing machine 6.

[0042] The double-row roller conveyor 21 is used to place the filled bag on the double-row roller conveyor 21, and the transmission roller is used to move the bag to the inside of the cabinet 1. The reciprocating conveying mechanism 22 is used to horizontally suspend and convey the filled bag, and the conveying line is divided into two sections, which are the conveying between the feeding opening and the bag unfolding device 3, and the conveying between the bag unfolding device 3 and the heat sealing machine 6. The two conveying lines are synchronized to cooperate with the automatic discharge of the conveying belt 23, thereby ensuring the smoothness of the filling and sealing process.

[0043] Refer to Figure 7 、 Figure 8As shown, the reciprocating conveying mechanism 22 comprises left-right symmetrical electromagnetic slide rails 221 and inverted U-shaped frames 222, the bottoms of both sides of the inverted U-shaped frames 222 are fixed with electromagnetic slide blocks 223 which slide horizontally along the interiors of the electromagnetic slide rails 221, both sides of the electromagnetic slide rails 221 are provided with in-place sensors B9, the inner sides of the top portions of the inverted U-shaped frames 222 are fixed with two parallel trapezoidal blocks 224, the interiors of the trapezoidal blocks 224 are provided with clamping assemblies 225, and the bottoms of both sides of the left-right inverted U-shaped frames 222 are connected through horizontal rods 226.

[0044] The inverted U-shaped frames 222 are used to facilitate the clamping height of the trapezoidal blocks 224 for the infusion bags to be at the upper portion of the bag body when clamping and conveying, so as to separate the clamping interval where the bag unfolding device 3 is located and the sealing interval where the heat sealing machine 6 is located, and meanwhile, the in-place sensors B9 are used to control the extension and shortening state of the clamping assemblies 225, so that the entire inverted U-shaped frame 222 is in the unclamped state when moving towards the discharge opening of the cabinet 1, and is in the clamped state when moving reversely, thereby further ensuring the stability and orderliness of the infusion bag during the entire processing and packaging movement, and improving the continuity of the feeding and discharging movement.

[0045] Referring to Figure 2 As shown, the left-right horizontal rods 226 move horizontally at the two side regions of the U-shaped plate 31, the spacing between the adjacent two trapezoidal blocks 224 is adapted to the spacing between the bag unfolding device 3 and the double-row drum conveyor 21, the spacing between the bag unfolding device 3 and the heat sealing machine 6 is adapted to the spacing between the bag unfolding device 3 and the double-row drum conveyor 21, and the position height of the trapezoidal blocks 224 is above the U-shaped plate 31.

[0046] The spacing design ensures the orderly combination between the infusion sealing and feeding and discharging processing sequences, and ensures the orderliness of the moving frequency of the reciprocating conveying mechanism 22, thereby improving the overall processing efficiency.

[0047] Referring to Figure 8 As shown, the clamping assembly 225 comprises a guide groove 2251 formed in the inner side of the clamping assembly 225, a U-shaped clamping plate 2253 is slidingly installed in the interior of the guide groove 2251, an electric push rod 2252 is connected between the inner side of the U-shaped clamping plate 2253 and the inner wall of the guide groove 2251, the clamping surface of the U-shaped clamping plate 2253 is provided with an antiskid pad, the clamping surface of the U-shaped clamping plate 2253 close to the double-row drum conveyor 21 is a plane, and the middle portion of the clamping surface of the U-shaped clamping plate 2253 close to the conveying belt 23 is serrated.

[0048] The different structures of the U-shaped clamping plates 2253 on different positions can adapt to the clamping effect according to the state of the infusion bag, the flat structure can stably clamp the un-infused bag body without forming wrinkles and damage on the surface of the bag body, which is beneficial to the effect of the subsequent infusion opening, the sawtooth structure can improve the clamping firmness of the infused bag body and prevent it from falling off, and meanwhile does not affect the subsequent sealing operation.

[0049] Working principle: the infusion bag is placed on the double-row roller conveyor 21, the transmission rollers on the double-row roller conveyor 21 convey the infusion bag to the inside of the cabinet 1, the control cabinet 5 cooperatively controls the starting of the electromagnetic sliding block 223 and the electromagnetic sliding rail 221, when the inverted U-shaped frame 222 moves to the double-row roller conveyor 21 along the electromagnetic sliding rail 221, one group of trapezoidal blocks 224 is located at the position of the infusion bag on the double-row roller conveyor 21, and the other group is located at the position of the infusion bag on the bag unfolding device 3, since the inverted U-shaped frame 222 moves to the limit position at this time, the in-place sensor B9 detects the inverted U-shaped frame 222, thereby controlling the extension of the electric push rod 2252 to make the U-shaped clamping plates 2253 on the left and right positions close to each other and clamp the infusion bag, and then the electromagnetic sliding block 223 is reversely moved along the electromagnetic sliding rail 221 until the inverted U-shaped frame 222 moves to the limit position on the other side, at this time, the infusion bag at the feeding port moves to the bag unfolding device 3, the infusion bag on the bag unfolding device 3 moves to the position of the heat sealer 6, at this time, the in-place sensor C10 detects the bag body, the heat sealer 6 is started to seal the top of the infused bag body, and the in-place sensor B9 at this position detects the inverted U-shaped frame 222, thereby controlling the electric push rod 2252 to be shortened and reset first, so that the clamping assembly 225 releases the clamping of the infusion bag, and then the electromagnetic sliding block 223 is reversely moved, so as to realize the continuous feeding, infusion, sealing and discharging of the infusion bag, and since the opening of the infusion bag is always closed during the feeding and discharging processes, the exposure and pollution of the bag before and after infusion are reduced, and the preservation effect of the prefabricated meat paste is improved.

[0050] Embodiment 3: refer to Figure 2 、 Figure 9 As shown in the figure, on the basis of embodiment one and embodiment two, the reversing action of the bi-directional airflow pump 444 in and out of the air promotes the formation of negative pressure around the air hole 442 when the telescopic discharging pipe 43 is inserted into the infusion bag, promotes the contraction of the top opening of the infusion bag inward, and then reduces the size of the top opening to prevent the prefabricated meat paste from spilling out during infusion.
