Description

Technical Field

[0001] This invention pertains to packaging machinery, and specifically relates to a cheese slice extrusion device. Background Technology

[0002] A cheese slice filling machine is a food packaging equipment specifically designed for the automated production of cheese slices, widely used in dairy processing, food manufacturing, and other industries. It typically includes a material conveying and melting system, a longitudinal sealing and feeding device, a thickness adjustment device, an extrusion device, a transverse sealing device, a forming and slicing device, a stacking device, a packaging and sealing device, and an automated control system. The extrusion device removes material from the cheese slices at the corresponding transverse sealing positions, dividing the accumulated material according to the bag's length to facilitate subsequent transverse sealing.

[0003] Existing extrusion devices typically include a support frame with a fixed clamping plate and a movable clamping plate. The movable clamping plate is slidably mounted on a slide rail on the support frame via a slider and is connected to a reciprocating drive mechanism on the support frame. Rectangular bosses are evenly distributed on the movable clamping plate on the side corresponding to the fixed clamping plate. During extrusion, the cheese slice pauses its movement, and the reciprocating drive mechanism drives the movable clamping plate to reciprocate. Through the cooperation of the movable and fixed clamping plates, the material at the corresponding horizontal sealing position on the cheese slice is extruded.

[0004] This cheese slice extrusion device has the following problems: 1. During extrusion, the cheese slices pause their movement and cannot move synchronously with other devices, reducing the production efficiency of cheese slices; 2. Power is supplied by the main motor, and the parameter positions are not easy to adjust; the structure is complex and the manufacturing cost is high. 3. The existing extrusion device does not extrude material cleanly, and material residue is easily left after extrusion, which will affect the subsequent horizontal sealing device, causing material to get stuck in the horizontal sealing device and affecting the horizontal sealing effect. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cheese slice extrusion device that is easy to adjust, can be synchronized with a cheese slice filling machine, and improves production efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution: A cheese slice extrusion device includes a support plate frame, on which two sets of driven rollers and driving rollers are installed side by side and arranged vertically. An extrusion belt is wound between each set of driven rollers and driving rollers. Multiple rectangular protrusions are evenly distributed on the outer edge of the extrusion belt. The rectangular protrusions on the two extrusion belts correspond one-to-one and the center distance between two adjacent rectangular protrusions is equal to the center distance between two adjacent horizontal sealing positions on the cheese slice. Multiple vertically arranged adjusting shafts are evenly distributed on the support plate frame between each group of driven rollers and driving rollers. The adjusting shafts are eccentric shafts, and a rotatable tensioning roller is installed on the eccentric shaft section in the middle of each adjusting shaft to tension the extrusion belt to extrude the cheese slices. A power source consisting of a servo motor and a reducer is provided on the rear side of the support plate frame. The output end of the power source is connected to one end of the central shaft of one of the active rollers. The central shafts of the two active rollers are connected by a gear pair to drive the two active rollers to rotate in opposite directions, thereby driving the two extrusion belts to run in opposite directions.

[0007] As a further preferred embodiment, the support plate frame includes a main upright plate and two secondary upright plates arranged in parallel. The two secondary upright plates are respectively fixed to the front side of the main upright plate by a connecting plate. Each set of driven rollers and driving rollers is installed between a secondary upright plate and the main upright plate. The front sides of the two secondary upright plates are detachably connected by a rectangular plate frame.

[0008] As a further preferred embodiment, a positioning plate is fixed on the inner side of each separate plate. Multiple positioning holes are evenly distributed on the positioning plate along the vertical direction. Each positioning hole is connected to an L-shaped notch and a locking screw is provided at the L-shaped notch. The front end of the adjusting shaft passes through the corresponding positioning hole and is locked by the locking screw to adjust the eccentricity of the adjusting shaft, thereby adjusting the gap between the two extrusion belts.

[0009] As a further preferred embodiment, the central shaft of the drive roller is mounted on the main upright plate and the corresponding split plate via two bearing sleeves and bearings, respectively, to facilitate assembly and disassembly.

[0010] As a further preferred embodiment, the two ends of the central shaft of the driven roller pass through the waist-shaped holes provided on the main plate and the secondary plate respectively and are fixed by nuts. The driven roller is installed on the corresponding central shaft by two sets of bearings to facilitate disassembly and assembly.

[0011] As a further preferred embodiment, the output end of the power source is connected to one end of the central shaft of one of the active rollers via a synchronous belt mechanism. A proximity switch is provided on the driven wheel side of the synchronous belt mechanism, and a cross-shaped switch baffle is fixed at one end of the central shaft of the active roller to trigger the proximity switch in order to control the position reset of the servo motor when the machine stops.

[0012] The beneficial effects of this invention are: 1. Because the extrusion device drives two active rollers to rotate in opposite directions through a power source consisting of a servo motor and a reducer, thereby driving two extrusion belts to run in opposite directions, and then the rectangular bosses on the two extrusion belts cooperate with each other to achieve continuous extrusion of cheese slices. During extrusion, the cheese slices do not need to stop moving, and can move synchronously with other devices of the cheese slice filling machine, thus improving production efficiency.

[0013] 2. Because multiple vertically arranged adjusting shafts are evenly distributed on the support plate frame between each group of driven rollers and driving rollers, and each adjusting shaft is an eccentric shaft with a rotatable tensioning roller installed on the eccentric shaft section in the middle of each adjusting shaft, the extrusion belt is tightened to extrude the cheese slice packaging material. Therefore, the extrusion is clean, and there is no material residue at the horizontal seal of the cheese slice after extrusion, which can avoid affecting the subsequent horizontal sealing device and improve the subsequent horizontal sealing effect.

[0014] 3. Because it uses a power source consisting of a servo motor and a reducer, the parameter positions are easy to adjust; the structure is simple, easy to disassemble and assemble, and the manufacturing cost is low. Attached Figure Description

Detailed Implementation

[0022] like Figures 1-6As shown, the present invention relates to a cheese slice extrusion device, comprising a support plate frame 1, on which two sets of driven rollers 3 and driving rollers 9 are mounted side by side. A racetrack-shaped extrusion belt 2 is wound between each set of driven rollers 3 and driving rollers 9. The extrusion belt is a synchronous belt and multiple rectangular protrusions 201 are evenly distributed on the outer edge of each extrusion belt 2. The rectangular protrusions 201 on the two extrusion belts 2 correspond one-to-one, and the center distance between two adjacent rectangular protrusions 201 is equal to the center distance between two adjacent horizontal sealing positions on the cheese slice.

[0023] The support frame 1 includes a rectangular main upright plate 101 and two separate upright plates 102 arranged in parallel. The two separate upright plates 102 are respectively fixed to the front side of the main upright plate 101 by a connecting plate 103 and screws. Each set of driven rollers 3 and driving rollers 9 are respectively installed between a separate upright plate 102 and the main upright plate 101. The front side of the two separate upright plates 102 is detachably connected by screws through a rectangular plate frame 104. Two connecting plates 105 are symmetrically fixed to the rear side of the main upright plate 101.

[0024] The central shaft 10 of the drive roller 9 is mounted on the main upright plate 101 and the corresponding split plate 102 via two bearing sleeves 11 and bearings. The bearing sleeves 11 are inserted into the corresponding main upright plate 101 or split plate 102 and fixed with screws for easy assembly and disassembly. The drive roller 9 is mounted on the corresponding central shaft 10 via a key connection, and multiple grooves that mate with the extrusion belt 2 are evenly distributed on the outer edge of the drive roller 9. The two ends of the central shaft 4 of the driven roller 3 pass through the oblong holes provided on the main upright plate 101 and the split plate 102 respectively and are fixed with nuts 12. The driven roller 3 is mounted on the corresponding central shaft 4 via two sets of bearings for easy assembly and disassembly.

[0025] Multiple vertically arranged adjusting shafts 7 are evenly distributed on the support plate frame 1 between each group of driven rollers 3 and driving rollers 9. In this embodiment, three adjusting shafts are used as an example. One end of the adjusting shaft 7 is inserted into the through hole on the main upright plate 101 through clearance fit, and the other end passes through the through hole on the corresponding separate plate 102 through clearance fit and exits through the inner cavity of the rectangular plate frame 104. The adjusting shaft 7 is an eccentric shaft, and a rotatable tensioning roller 5 is installed on the eccentric shaft section in the middle of each adjusting shaft 7 through a bearing. Multiple grooves that cooperate with the extrusion belt 2 are evenly distributed on the outer edge of the tensioning roller 5 to tighten the extrusion belt 2 to extrude the cheese slices.

[0026] A rectangular positioning plate 8 is fixed to the inner side of each separate plate 102 by screws. Multiple positioning holes 801 are evenly distributed on the positioning plate 8 along the vertical direction. Each positioning hole 801 is connected to an L-shaped notch and a locking screw 6 is provided at the L-shaped notch. The front end of the adjusting shaft 7 passes through the corresponding positioning hole 801 and is locked by the locking screw 6 to adjust the eccentricity of the adjusting shaft 7, thereby adjusting the gap between the two extrusion belts 2.

[0027] A power source consisting of a servo motor 17 and a reducer 16 is provided on the rear side of the support frame 1. The power source is fixed on a motor bracket 18 and its output end is connected to one end of the central shaft of one of the drive rollers 9 via a synchronous belt mechanism 19. The central shafts 10 of the two drive rollers 9 are connected by a gear pair 20 to drive the two drive rollers 9 to rotate in opposite directions, thereby driving the two extrusion belts 2 to run in opposite directions. On the central shaft of the other drive roller 9, at both ends of the drive roller 9, a split-type retaining sleeve 22 is fitted and fixed with screws to facilitate adjustment of the axial position of the drive roller 9 on the central shaft so that the two drive rollers 9 are aligned with each other.

[0028] A proximity switch 15 is mounted on the driven pulley side of the synchronous belt mechanism 19 via a switch bracket 14. A cross-shaped switch stop 21 is fixed to one end of the central shaft 10 of one of the driving rollers 9 by screws to trigger the proximity switch 15, thereby controlling the position reset of the servo motor 17 when the machine stops. A bearing seat 13 is mounted on the central shaft 10 of one of the driving rollers 9 near the driven pulley of the synchronous belt mechanism 19 via a bearing to assist in supporting the central shaft.

[0029] During operation, the device is bolted to the body of the cheese slice filling machine via two connecting plates 105 of the support frame 1, a motor bracket 18, and a bearing seat 13. The servo motor 17 is started, driving the central shaft of one of the drive rollers 9 to rotate at low speed via the synchronous belt mechanism 19. This, in turn, drives the two drive rollers 9 to rotate in opposite directions via the gear pair 20, thereby causing the two extrusion belts 2 to rotate in opposite directions. By adjusting the eccentricity of the adjusting shaft 7, the gap between the two extrusion belts 2 can be adjusted by the tensioning roller 5, thus separating the material accumulated inside the cheese slice packaging through the extrusion belts 2. This removes the material at the corresponding horizontal sealing position on the cheese slice packaging, facilitating subsequent horizontal sealing.

[0030] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
