Novel cutting device for food packaging machine

Abstract

A novel cutting device for a food packaging machine is characterized in that when a semi-finished film belt runs between an upper bracket and a lower bracket of a transverse cutter, a lower supporting cylinder of the transverse cutter pushes a cutter support cylinder seat to drive a transverse cutter seat plate to move upwards to a locking lower seat through a cylinder connecting block, a cut packaging film is clamped between the upper bracket and the lower bracket of the transverse cutter, and the lower supporting cylinder of the transverse cutter stops running; the transverse blade driving air cylinder drives the transverse blade to move upwards through the transverse blade clamping block, the transverse blade stretches out to cut the packaging film open and then moves downwards to return to the initial position, meanwhile, the transverse blade lower supporting air cylinder moves downwards to drive the transverse blade base plate to return to the initial position, and the next circulation starts. Due to the fact that the transverse cutting blade is mostly in the transverse cutter lower bracket in the whole machining process, objects or human limbs outside the transverse cutting blade cannot touch the blade, safety is improved, due to the fact that the transverse cutting blade driving air cylinder only drives the transverse cutting blade to operate, the mass of the transverse cutting blade is small, air cylinder power is small, energy input is reduced, and machining efficiency is improved. And the impact force generated in the operation process is small, the inertia influence is greatly reduced, and the cutting precision is improved.

Description

Technical Field

[0001] This utility model pertains to the field of food processing and packaging equipment. Background Technology

[0002] Currently available commercially available equipment typically employs an integrated blade and blade holder drive design in practical applications. When it is necessary to cut packaging into smaller pieces, the cutter positioned above the packaging film punches downwards to cut the semi-finished packaging bag into smaller pieces, while the cutter positioned below the packaging film punches upwards to cut the semi-finished packaging bag into smaller pieces. The disadvantages are: 1. The rigid connection between the blade and the drive mechanism results in a bulky overall structure; 2. It is susceptible to inertia, and deviations are prone to occur during high-speed cutting; 3. Exposed cutters are unsafe, easily causing accidents and increasing safety hazards. Summary of the Invention

[0003] To overcome the above problems, this utility model proposes a novel cutting device for a food packaging machine. Its structure includes a cylinder seat reinforcing plate, a guide post connecting plate, a cross blade upper support, a cross blade guide post, a locking lower seat, a linear bearing, a cross blade lower support cylinder, a cylinder connecting block, a cross blade seat plate, a cross blade cylinder seat, a cross blade clamping block, a cross-cutting blade, a cross blade lower support, and a cross blade drive cylinder. The cross blade lower support cylinder is connected to the cylinder seat reinforcing plate; the cylinder seat reinforcing plate is fixed to the guide post connecting plate; the cross blade guide post is fixed to the guide post connecting plate; the locking lower seat is fixed to the cross blade guide post; both ends of the cross blade seat plate are fixed to the linear bearing; the linear bearing... A linear bearing is mounted on the cross-blade guide post; the upper cross-blade bracket is fixed on the cross-blade guide post; the lower cross-blade support cylinder is connected to a cylinder connecting block; the cross-blade seat plate is connected to the lower cross-blade support cylinder via the cylinder connecting block; the cross-blade drive cylinder is fixed on the cross-blade cylinder seat; the cross-blade cylinder seat is mounted on the cross-blade seat plate; the lower cross-blade bracket is fixed on the cross-blade seat plate; the lower cross-blade bracket contains a cross-cutting blade; the cross-blade drive cylinder is connected to the cross-cutting blade via a cross-blade clamping block. Beneficial effects

[0004] Compared to existing equipment, a new type of cutting device for food packaging machines employs a multi-cylinder design. The cross-blade slice is mounted below the packaging film being cut and is driven by an independent cylinder. During the cutting process, the slice is pushed upwards by the cylinder. Because the cross-blade slice has a small mass, the cylinder power is relatively low, reducing energy input. Furthermore, the impact force generated during operation is small, greatly reducing inertia and improving cutting accuracy. Since the cross-blade spends most of the processing time inside the lower support of the cross-blade, external objects or human limbs cannot touch the blade, thus improving safety.

[0009] The cross-blade lower support cylinder 7 is connected to the cylinder seat reinforcing plate 1. The cylinder seat reinforcing plate 1 is fixed to the guide post connecting plate 2. The cross-blade guide post 4 is fixed to the guide post connecting plate 2. The locking lower seat 5 is fixed to the cross-blade guide post 4. The two ends of the cross-blade seat plate 9 are fixed to the linear bearings 6. The linear bearings 6 are installed on the cross-blade guide post 4. The cross-blade upper support bracket 3 is fixed to the cross-blade guide post 4. The cross-blade lower support cylinder 7 is connected to the cylinder connecting block 8. The cross-blade seat plate 9 is connected to the cross-blade lower support cylinder 7 through the cylinder connecting block 8. The cross-blade drive cylinder 14 is fixed to the cross-blade cylinder seat 10. The cross-blade cylinder seat 10 is installed on the cross-blade seat plate 9. The cross-blade lower support bracket 13 is fixed to the cross-blade seat plate 9. The cross-blade lower support bracket 13 contains the cross-cutting blade 12. The cross-blade drive cylinder 14 is connected to the cross-cutting blade 12 through the cross-blade clamping block 11.

[0010] When the packaged semi-finished film strip passes between the upper cross-blade support 3 and the lower cross-blade support 13, the cross-blade support cylinder 7 pushes the cross-blade support cylinder seat 7, which in turn drives the cross-blade support plate 9 upward through the cylinder connecting block 8. When it reaches the locking lower seat 5, the cut packaging film is clamped between the upper cross-blade support 3 and the lower cross-blade support 13. The cross-blade support cylinder 7 stops operating, and the cross-blade drive cylinder 14 drives the cross-cutting blade 12 upward through the cross-blade clamping block 11. The cross-cutting blade 12 extends and cuts the packaging film. Then, the cross-blade drive cylinder 14 drives the cross-cutting blade 12 downward back to the initial position, and at the same time, the cross-blade support cylinder 7 moves downward, driving the cross-blade support plate 9 back to the initial position, and the next cycle begins. Since the cross-cutting blade 12 is mostly inside the cross-cutting support 13 during the entire processing, external objects or human limbs cannot touch the blade, thus improving safety. Since the cross-cutting blade drive cylinder 14 only drives the cross-cutting blade 12, and the cross-cutting blade 12 has a small mass, the cylinder power is relatively small, reducing energy input. Furthermore, during the cutting process, only the cross-cutting blade 12 comes into contact with the packaging film being cut, so the noise generated is relatively small.

[0011] During operation, after the semi-finished packaging film being cut stops between the upper support 3 and the lower support 13 of the horizontal blade, the lower support cylinder 7 drives the horizontal blade seat plate 9 to move up and down through the cylinder connecting block 8, lifting the horizontal blade seat plate 9 upwards. When the horizontal blade seat plate 9 drives the lower support 13 to the locking lower seat 5, the semi-finished packaging film being cut is clamped and fixed. The lower support cylinder 7 stops running, and the horizontal blade drive cylinder 14 drives the horizontal cutting blade 12 upwards through the horizontal blade clamping block 11. The horizontal cutting blade 12 extends and cuts the packaging film. Then, the horizontal blade drive cylinder 14 drives the horizontal cutting blade 12 downwards to return to the initial position. At the same time, the lower support cylinder 7 moves downwards, driving the horizontal blade seat plate 9 back to the initial position, and the next cycle begins.
