Description

Technical Field

[0001] This invention relates to an improved filling machine, and more particularly to an integrated filling and cutting machine that combines filling and cutting into one unit. Background Technology

[0002] The filling and sealing machine integrates filling, sealing, and cutting into one unit. Filling and sealing typically includes filling and sealing, and is suitable for packaging liquids such as oral liquids and beauty serums. These products are made from sheet rolls, including materials such as plastic and aluminum foil. The sheet rolls are processed into three-dimensional continuous rolled materials through methods such as vacuum forming or molding. The bottom of the rolled material has a bottom sealing edge, while the top of the rolled material retains a sealing edge. The protruding three-dimensional part of the rolled material is the forming part. After filling and sealing, the rolled material becomes a finished product roll, which is finally cut into individual products.

[0003] Existing filling and sealing machines use intermittent conveying and intermittent operation. The roll material stops conveying during the forming, filling, and cutting operations, and then conveys one unit roll material forward after the forming, filling, and cutting operations are completed. This type of filling and sealing machine has production efficiency problems. Summary of the Invention

[0004] In view of the technical problems existing in the background art, the technical problem solved by the present invention is to provide a continuous production filling and sealing machine that greatly improves production efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the filling and sealing machine is characterized by including a material roll, a traction mechanism, a forming mechanism, a filling and sealing mechanism, and a driving mechanism for driving the forming mechanism and the filling and sealing mechanism to move back and forth synchronously. The traction mechanism includes a front traction component and a rear traction component, which synchronously and continuously feed the roll material. The forming mechanism and the filling mechanism are sequentially arranged and move between the rear traction mechanism and the front traction mechanism. When the forming mechanism and the filling mechanism are in operation, the driving mechanism drives the forming mechanism, the filling mechanism and the roll material to move forward synchronously. After the operation is completed, the drive mechanism drives the molding mechanism and the filling mechanism to quickly retract and reset.

[0006] After forming and filling, the sheet roll becomes a finished roll. The sheet roll and the finished roll are the same continuous roll. The rear traction component pulls the sheet roll, and the front traction component pulls the finished roll. The two are pulled synchronously, increasing the traction force and reducing the stretching problem of the roll. The forming mechanism and filling mechanism of this invention operate during the traction process of the roll and quickly reset after completing the operation, realizing continuous conveying operation and greatly improving production efficiency compared with the prior art. Preferably, the molding mechanism and the filling mechanism are connected and slidably disposed on the first guide rail, which is longitudinally disposed on the frame. The driving mechanism includes a screw, a nut, and a first motor that drives the screw to rotate. The first motor is connected to a controller. The nut is threadedly connected to the screw. The screw is rotatably mounted on the frame and parallel to the first guide rail. The nut is connected to the molding mechanism and / or the filling mechanism. The first motor drives the screw to rotate, causing the nut to move longitudinally, thus moving the molding mechanism and the filling mechanism forward or backward along the first guide rail. The movement speed of the molding mechanism and the filling mechanism is controlled by the controller, which controls the rotational speed of the first motor.

[0007] Preferably, the front traction component includes a vertically arranged rotating roller, an upper pressure roller, and a lower pressure roller. The rotating roller is connected to a second motor. The circumferential side of the rotating roller includes an upper pressing surface, a lower pressing surface, and a clearance groove disposed between the upper and lower pressing surfaces. The upper and lower pressure rollers rotate and press against the upper and lower pressing surfaces of the rotating roller, respectively. The upper and lower pressure rollers press against the upper and lower pressing surfaces of the rotating roller, respectively, gripping the upper and lower ends of the roll material. The protruding forming part corresponds to the clearance groove of the rotating roller, so that the forming part is not subjected to friction or compression, maintaining a complete forming state. The second motor drives the rotating roller to rotate, and the two ends of the roll material move forward under the traction of the rotating roller and the upper and lower pressure rollers. The second motor drives the rotating roller to rotate at a constant speed, so that the roll material moves forward at a constant speed, thus realizing continuous conveying of the roll material.

[0008] Preferably, the upper pressure rollers are rotatably mounted on the support, and there are several upper pressure rollers arranged in an arc shape along the upper pressing surface. This increases the contact area between the coil and the rotating roller, increases the traction force on the coil, makes the coil move forward more stably, and avoids slippage.

[0009] Preferably, the support includes a column, an upper mounting plate, and a lower mounting plate. The upper and lower mounting plates are mounted on the column and have a gap between them and the rotating roller. The upper mounting plate has a first arc-shaped segment on its side facing the rotating roller that matches the upper pressing surface, and the lower mounting plate has a second arc-shaped segment on its side facing the rotating roller that matches the lower pressing surface. The first and second arc-shaped segments are vertically aligned. The upper pressure roller is rotatably mounted on the first arc-shaped segment, and the lower pressure roller is rotatably mounted on the second arc-shaped segment. The first and second arc-shaped segments arrange several upper and several lower pressure rollers into an arc shape, pressing them against the upper and lower pressing surfaces of the rotating roller.

[0010] The upper pressure roller is rotatably connected to a central shaft; The first arc-shaped segment has a horizontal cavity for accommodating the upper pressure roller and a vertical mounting hole for inserting the central shaft. Both ends of the central shaft are equipped with pressure rods to adjust the pressure between the upper pressure roller and the upper pressing surface. The pressure rods are horizontally positioned and threadedly connected to the upper mounting plate, pressing against the central shaft. By rotating the pressure rods, they extend horizontally into the mounting hole and press against the central shaft, applying radial pressure relative to the central shaft. This causes the upper pressure roller to press against the upper pressing surface of the rotating roller. If the coiled material is thin, the pressure rod extends deeper into the mounting hole; if the coiled material is thick, the pressure rod retracts. This adjustment of the force exerted on the coiled material by the upper pressure roller and the upper pressing surface achieves optimal traction.

[0011] Preferably, the rotating roller includes an outer cylinder and an inner shaft, with the outer cylinder sleeved around the inner shaft. The outer cylinder and the inner shaft are circumferentially linked, and the inner shaft is connected to a second motor. The outer cylinder is axially movable relative to the inner shaft. The first motor drives the inner shaft to rotate, which in turn drives the rotating roller to rotate. If the height of the coiled material changes, the outer cylinder moves axially relative to the inner shaft, so that the upper and lower pressing surfaces and the clearance grooves on the outer cylinder correspond to the height of the coiled material.

[0012] A limiting groove is provided on the circumferential side of the inner shaft, and a protrusion is provided on the inner wall of the outer cylinder, the protrusion being placed within the limiting groove; the outer cylinder is connected to a screw, the screw being vertically arranged and threadedly connected to the inner shaft. The outer cylinder is linked to the inner shaft through the protrusion; rotating the screw causes the inner shaft to move axially, resulting in the screw moving up and down relative to the inner shaft, and the movement of the screw causes the outer cylinder connected to the screw to move up and down relative to the inner shaft.

[0013] Preferably, the filling and sealing machine also includes a cutting mechanism, and a continuous finished product roll storage mechanism is provided between the cutting mechanism and the front traction component. The finished roll material storage mechanism includes a storage station for storing finished roll materials and a feeding component for conveying finished roll materials to the cutting mechanism. The feeding component conveys finished roll materials intermittently.

[0014] The front traction component continuously conveys the finished roll material, which is stored in the storage station. The feeding component conveys the stored finished roll material to the cutting mechanism. In this way, the length of the finished roll material conveyed by the feeding component to the cutting mechanism is not affected by the operation of the filling mechanism and the conveying of the traction mechanism, so that the feeding component conveys the material to a fixed length with precision. Precise fixed-length conveying ensures precise cutting by the cutting mechanism.

[0015] Preferably, the intermittent conveying speed of the feeding component is not slower than the conveying speed of the traction mechanism; The finished roll material storage mechanism also includes a detection component for detecting the storage amount of the finished roll material at the storage station. The detection component, the feeding component, and the cutting mechanism are all connected to the controller. When the detection component detects that there is insufficient finished roll material at the storage station, the controller sends a command to the feeding component and the cutting mechanism, and both stop operating.

[0016] By collecting information from the detection components, the cutting and finished product storage are coordinated, ensuring that there is a sufficient amount of finished product roll material when the feeding component is feeding. This prevents the roll material from becoming loose due to excessive roll material, and also prevents the roll material from becoming stretched due to insufficient feeding due to insufficient roll material, thus eliminating problems of unstable and inaccurate feeding.

[0017] Preferably, the storage station is equipped with a storage component, which includes a tension roller and an external force component. The tension roller is vertically arranged and rotatably mounted on a slide block, which is slidably mounted on a guide rail. The guide rail is horizontally mounted on the frame. The external force component is connected to the tension roller, and the finished roll is wound around the tension roller. The tension roller is simultaneously subjected to the forces of the finished roll and the external force component. The feeding component pulls the finished roll, and the forces exerted by the finished roll on the tension roller and the external force component on the tension roller are balanced by the movement of the tension roller on the guide rail. This keeps the finished roll stored in the storage station under tension, ensuring stable and precise delivery of the finished roll to a fixed length.

[0018] Preferably, the storage component further includes a limiting element, which comprises an upper baffle and a lower baffle, both mounted on two columns. The distance between the upper and lower baffles matches the height of the finished roll, and the upper and lower baffles and the two columns form a cavity through which the finished roll passes. The finished roll passes through the cavity, around the tension roller, and then exits from the cavity into the feeding component. The limiting element ensures stable upright conveying of the finished roll, preventing the formed roll from moving up and down. Attached Figure Description

[0028] The following description, in conjunction with the accompanying drawings, details the embodiments and working principles of the present invention. In the figures, the X-axis represents the horizontal direction, also known as the left-right direction; the Y-axis represents the vertical direction, also known as the front-back direction, with the arrow on the Y-axis pointing in the direction of the roll material conveying, also known as the forward direction; and the Z-axis represents the vertical direction, also known as the up-down direction.

[0029] This type of filling and sealing machine includes a material roll 44, a traction mechanism, a forming mechanism 45, a filling and sealing mechanism 46, and a drive mechanism that drives the forming and filling mechanisms to move synchronously back and forth. The traction mechanism includes a front traction component 1 and a rear traction component 2, which synchronously and continuously convey the roll material. The forming mechanism 45 and the filling and sealing mechanism 46 are sequentially arranged between the rear traction mechanism 2 and the front traction mechanism 1. When the forming and filling mechanisms are operating, the drive mechanism drives the forming and filling mechanisms to move forward synchronously with the roll material, that is, the roll material is formed and filled during the traction process. After the operation is completed, the drive mechanism drives the forming and filling mechanisms to quickly retreat and reset, thus eliminating the need for additional time for forming and filling operations and greatly accelerating production efficiency. After being formed and filled, the sheet roll becomes a finished roll. The sheet roll and the finished roll are the same continuous roll. The sheet roll is placed on the roll shaft 44. The rear traction component pulls the sheet roll, and the front traction component pulls the finished roll. The two are pulled synchronously to increase the traction force and reduce the stretching problem of the roll.

[0030] The molding mechanism 45 and the filling mechanism 46 are connected and slidably mounted on the first guide rail 50, which is longitudinally mounted on the frame 30. The driving mechanism includes a screw 47, a nut 48, and a first motor 51 that drives the screw to rotate. The first motor is connected to a controller. The nut 48 is threadedly connected to the screw 47. The screw is rotatably mounted on the frame and parallel to the first guide rail. The nut is connected to the molding mechanism and / or the filling mechanism. The first motor drives the screw to rotate, causing the nut to move longitudinally, thus moving the molding mechanism and the filling mechanism forward or backward along the first guide rail. The movement speed of the molding mechanism and the filling mechanism is controlled by the controller, which controls the rotation speed of the first motor.

[0031] The front traction component 1 includes a vertically arranged rotating roller 6, an upper pressure roller 7, and a lower pressure roller 8. The rotating roller 6 is connected to a second motor 10. The circumferential side of the rotating roller includes an upper pressing surface 3, a lower pressing surface 5, and a clearance groove 4 disposed between the upper pressing surface and the lower pressing surface. The upper pressure roller 7 and the lower pressure roller 8 rotate and press against the upper pressing surface 3 and the lower pressing surface 5 of the rotating roller, respectively, gripping the upper and lower ends of the roll material between them. When the second motor drives the rotating roller 6 to rotate, the rotating roller rotates in opposite directions with the upper and lower pressure rollers, causing the roll material to be conveyed forward. The second motor 10 drives the rotating roller 6 to rotate at a uniform speed, and the finished roll material moves forward at a uniform speed, thus realizing the continuous conveying of the roll material. The sealing edge 41 of the finished roll is held by the upper pressure roller 7 and the upper pressing surface 3, and the bottom sealing edge 43 of the finished roll is held by the lower pressure roller 8 and the lower pressing surface 5. The protruding forming part 42 of the finished roll corresponds to the relief groove 5, which accommodates the protruding forming part, preventing the forming part from being rubbed or squeezed, and maintaining the complete forming state. The rear traction component 2 can also adopt the structure of the front traction component 1 described above. Since the rear traction component tractions the sheet roll, it is preferable that the rear traction component 2 uses two pressing traction rollers 22, and one of the traction rollers is connected to the third motor 23. The two traction rollers rotate in opposite directions to achieve traction of the sheet roll. Moreover, the contact area between the traction roller 22 and the sheet roll is large, and the traction is more stable. In addition, the front traction component and the rear traction component are far apart on the frame, and the use of two motors for driving not only facilitates installation but also simplifies the structure.

[0032] The upper pressure roller 7 is rotatably mounted on the support. Several upper pressure rollers are arranged in an arc shape along the upper pressing surface 3, ensuring the rolled material adheres closely to the upper pressing surface 3 and increasing the contact area. In the figure, three upper pressure rollers 7 and three lower pressure rollers 8 are evenly mounted on the support. These multiple rollers increase the contact area between the rolled material and the rotating roller, increasing the traction force on the rolled material and making its forward movement more stable, preventing slippage during traction. To facilitate adjustment of the height of the upper pressure rollers 7 and 8, the support includes a column 9, an upper mounting plate 15, and a lower mounting plate 16. The upper and lower mounting plates are mounted on the column, and there are gaps between the upper and lower mounting plates and the rotating roller 6, preventing the rolled material from contacting the mounting plates. The upper mounting plate 15 has a first arc-shaped segment 21 on its side facing the rotating roller, matching the upper pressing surface. The lower mounting plate has a second arc-shaped segment 24 on its side facing the rotating roller, matching the lower pressing surface. The first and second arc-shaped segments are vertically aligned. The upper pressure roller 7 is rotatably mounted on the first arc-shaped segment 21, and the lower pressure roller 8 is rotatably mounted on the second arc-shaped segment 24. The first and second arc-shaped segments arrange several upper and lower pressure rollers into an arc shape, pressing them against the upper and lower pressing surfaces of the rotating roller 6. The upper pressure roller 7 is rotatably connected to a central shaft 18, which is mounted on the upper mounting plate and does not rotate. The upper pressure roller is coaxially connected to the central shaft via a bearing, and the upper pressure roller rotates relative to the central shaft. The first arc-shaped segment has a horizontally accommodating cavity 19 for accommodating the upper pressure roller and a vertically accommodating mounting hole 20 for inserting the central shaft. The mounting hole extends from top to bottom through the accommodating cavity. The upper pressure roller 7 is placed inside the accommodating cavity 19, and the upper and lower ends of the central shaft 18 are placed inside the mounting hole 20. Both the upper and lower ends of the central shaft are equipped with a top pressure rod 17 for adjusting the pressure between the upper pressure roller and the upper pressing surface. The top pressure rod is horizontally arranged and threadedly connected to the upper mounting plate 15. The top pressure rod extends into the mounting hole and presses against the central shaft 18, causing the upper pressure roller to press against the upper pressing surface of the rotating roller. The pressure between the upper pressure roller and the rotating roller is adjusted by adjusting the depth of the top pressure rod. When the coil material is thin or the pressure applied to it is insufficient, rotate the top pressure rod 17 to penetrate deeper into the mounting hole 20, pressing against the central shaft 18 and increasing the pressure between the upper pressure roller and the upper pressing surface. When the coil material is thick or the pressure applied to it is too high, rotate the top pressure rod in the opposite direction to retract it, reducing the pressure between the upper pressure roller and the upper pressing surface. This adjustment of the pressure applied to the coil material achieves the best traction effect. The lower pressure roller can also adopt the above mounting structure.

[0033] The specifications of the coiled material and its height on the frame may vary to accommodate different coiled material traction. The rotating roller 6 includes an outer cylinder 11 and an inner shaft 12. The outer cylinder is sleeved outside the inner shaft, which acts as the rotating shaft of the rotating roller. The outer cylinder 11 and the inner shaft 12 are circumferentially linked, meaning that rotation of the inner shaft drives rotation of the outer cylinder. The inner shaft is connected to a second motor 10. The outer cylinder 11 is axially movable relative to the inner shaft 12, meaning it can rise and fall relative to the inner shaft. The second motor 10 drives the inner shaft 12 to rotate, causing the rotating roller 6 to rotate. If the height of the coiled material changes, the outer cylinder 11 moves axially relative to the inner shaft 12, aligning the upper and lower pressing surfaces and clearance grooves on the outer cylinder with the height of the coiled material. Specifically, as shown in the attached diagram, a limiting groove is provided on the circumferential side of the inner shaft, and a protrusion 14 is provided on the inner wall of the outer cylinder 11. The protrusion is placed within the limiting groove, and the outer cylinder 11 is linked to the inner shaft 12 through the protrusion 14. The outer cylinder is connected to a screw 13, which is vertically positioned and threadedly connected to the inner shaft 12. Rotating the screw causes the inner shaft to rise or fall relative to it, as the inner shaft cannot move axially. The rise or fall of the screw 13, in turn, causes the outer cylinder 12 connected to the screw to rise or fall relative to the inner shaft. The upper mounting plate 15 and lower mounting plate 16 are movably mounted on the column 9 and are locked to the column by locking bolts. When the height of the coil changes, the upper and lower mounting plates are moved to adjust the height of the upper and lower pressure rollers accordingly, meeting the requirements of the coil.

[0034] The filling and sealing machine also includes a cutting mechanism. A continuous finished product roll storage mechanism is provided between the cutting mechanism and the front traction component. The finished product roll storage mechanism includes a storage station for storing finished product rolls and a feeding component 27 for feeding finished product rolls to the cutting mechanism. The feeding component intermittently feeds finished product rolls. The front traction mechanism 1 continuously feeds finished product rolls, which are stored in the storage station. The feeding component 27 feeds the stored finished product rolls to the cutting mechanism 26. In this way, the length of finished product rolls fed by the feeding component to the cutting mechanism is not affected by the operation of the filling and sealing mechanism and the feeding of the traction mechanism, so that the feeding component 27 feeds precisely to a fixed length. Precise fixed-length feeding ensures precise cutting by the cutting mechanism.

[0035] If the finished roll material at the storage station is in a slack state, it will affect the accuracy of the fixed-length conveying of the feeding component. To keep the finished roll material at the storage station taut, the storage station is equipped with a storage component, which includes a tension roller 29 and an external force component 36. The tension roller is vertically arranged and rotatably mounted on a slide block 37, which is slidably mounted on a guide rail 38. The guide rail is horizontally mounted on the frame 30. The external force component 36 is connected to the tension roller 29, and the finished roll material is wound around the tension roller. The tension roller 29 is simultaneously subjected to the forces of the finished roll material and the external force component 36. The force exerted by the finished roll material on the tension roller comes from the feeding component 27. The external force component can be a tension spring, which is low in cost and easy to install. The feeding component pulls the finished roll material, and the tension force exerted by the finished roll material on the tension roller is opposite in direction to the tension force exerted by the tension spring on the tension roller. (See attached diagram) Figure 3 The tension force exerted on the tension roller by the finished roll material is in direction A, and the tension force exerted on the tension roller by the tension spring is in direction B. When the feeding component 27 feeds the finished roll material to the cutting mechanism, the amount of finished roll material in the storage station decreases, and the tension force of the finished roll material causes the tension roller to move along the guide rail 38 in the traction direction, and the tension spring 36 is stretched. When the amount of finished roll material in the storage station increases, the tension spring pulls the tension roller to move in the opposite direction along the guide rail, so that the finished roll material wound on the tension roller remains taut and avoids slack. To ensure the stability of the finished coil during traction and prevent vertical movement, the storage component also includes a limiting element. This limiting element comprises an upper baffle 31 and a lower baffle 32, both mounted on two uprights 33. The distance between the upper and lower baffles matches the height of the finished coil. The upper and lower baffles, along with the two uprights, form a cavity 39 through which the finished coil passes. The finished coil passes through the cavity, around the tension roller 29, and then exits into the feeding component 27. The limiting element restricts the vertical position of the finished coil during conveying, preventing deviation and further improving the accuracy of fixed-length feeding. (See appendix) Figure 8 The finished roll has a protruding forming part 42. Using a regular roller with a flat surface would cause the forming part to be squeezed. The circumferential side of the tension roller 29 is provided with a relief groove 35 corresponding to the forming part of the finished roll. The top sealing edge 41 and the bottom sealing edge 43 of the finished roll are respectively attached to the side 34 above and below the relief groove. In this way, the finished roll covers the tension roller 29 and the top sealing edge and the bottom sealing edge are attached to the side 34 of the tension roller, while avoiding the forming part being squeezed.

[0036] The feeding component 27 pulls the finished roll material, and the feeding component can also adopt the structure of the aforementioned front traction component 1. The intermittent conveying speed of the feeding component 27 is not slower than the conveying speed of the traction mechanism 1. That is to say, the finished roll material conveyed by the traction mechanism to the storage station by the cutting mechanism 26 can be consumed, so that the traction mechanism can maintain continuous conveying and the storage station will not exceed the storage capacity, thereby increasing the processing speed of the filling machine. If the finished roll material at the storage station is insufficient, the cutting mechanism 26 can stop working and wait for the roll material. In order to enable the filling machine to operate at high speed and stably, the finished roll material storage mechanism 25 also includes a detection component for detecting the storage capacity of the finished roll material at the storage station (not shown in the figure). The detection component, feeding component, and cutting mechanism are all connected to the controller. When the detection component detects that the finished roll material at the storage station is insufficient, the controller sends a command to the feeding component 27 and the cutting mechanism 26, and both the feeding component and the cutting mechanism stop working until the finished roll material at the storage station is sufficient, at which point the feeding component and the cutting mechanism resume working. This invention uses information collected by a detection component to coordinate cutting and finished product storage, ensuring sufficient finished product roll material is supplied during feeding. This prevents both excessive roll material causing slack and insufficient material causing stretching, thus eliminating feeding instability and inaccuracy, and enabling the filling machine to operate at high speed and stably. The detection component includes a first position sensor and a second position sensor to detect the position of the tension roller. These two sensors respectively collect the critical position of the tension roller on the guide rail. The feeding component pulls the finished product roll material, which in turn pulls the tension roller along the guide rail. If the first position sensor detects a low level of finished roll material at the storage station, it indicates that the amount of finished roll material stored at the storage station has reached a critical value. Feeding and cutting operations must be stopped, and the storage station waits for the amount of finished roll material to increase. When this happens, the tension spring causes the tension roller to move in the opposite direction along the guide rail, thus eliminating the stop command and resuming feeding and cutting operations. If the amount of finished roll material at the storage station is high, and the second position sensor detects a high level of finished roll material at the storage station, it indicates that the amount of finished roll material stored at the storage station has reached a critical value. In this case, the feeding speed and cutting frequency are increased to accelerate the consumption of finished roll material at the storage station. To further improve cutting accuracy, the finished roll material storage mechanism also includes a third position sensor for detecting the position of the finished roll material. This third position sensor is connected to the controller. During cutting, the feeding component pulls the finished roll material, and based on the information collected by the third position sensor, the controller sends a command to the cutting mechanism.The third position sensor detects a specific position of the finished roll material, such as a protruding part of the rolled material after it has been formed. The specific position can be set to one end or one side edge of the formed part. It is best to set the third position sensor close to the feeding component. When the feeding component delivers the finished roll material of a fixed length and the third position sensor detects the specific position, the controller sends a cutting command to the cutting mechanism to perform the cutting operation. If the third position sensor does not detect the specific position, it means that the position of the finished roll material at the cutting station is not accurate. The controller sends a command to the cutting mechanism not to cut, thus ensuring that the cutting position is accurate.
