Abstract
Description
Technical Field
[0001] The present invention relates to a coffee filter bag processing device, and more particularly to a coffee filter bag cutting device. Background Art
[0002] A coffee filter bag cutting device is a device specially designed for cutting coffee filter bags (usually made of filter paper or other materials suitable for filtering coffee).
[0003] First, the raw materials of the coffee filter bag (such as paper, cloth, etc.) are placed at the input end of the device. Through the conveying mechanism (such as a conveyor belt or roller), the raw materials are stably conveyed to the cutting area. When the raw materials arrive at the cutting area, the cutting tool (such as a blade, laser cutter, etc.) starts working.
[0004] The cutting device of the coffee filter bag is loading the filter bag. The filter bag material itself has elastic or deformable characteristics. When subjected to external force during the loading process, it is easy to deform, resulting in surface wrinkles. The wrinkles on the surface of the filter bag make it impossible for the cutting tool to accurately fit the edge of the filter bag during the cutting process, thereby affecting the cutting accuracy and causing the filter bag to be inaccurate in size or irregular in shape.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention
[0006] In view of the shortcomings of the prior art, the present invention aims to provide a coffee filter bag cutting device. When the filter bag passes through two rubber leveling rollers rotating in opposite directions, friction will be generated between the rollers and the filter bag. This friction helps to flatten the wrinkles or uneven parts on the surface of the filter bag. The rotation of the rubber leveling rollers not only generates friction, but also slightly stretches and compresses the filter bag. The alternating action of stretching and compressing helps to further eliminate the wrinkles on the surface of the filter bag. The surface of the filter bag after leveling is smoother, which helps the cutting tool to fit the edge of the filter bag more accurately, thereby improving the cutting accuracy.
[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a coffee filter bag cutting device, comprising a base, a vertical plate fixedly installed on the rear side of the upper end of the base, a discharge roller movably connected to the left side of the front end of the vertical plate, a filter bag movably connected to the discharge roller, two rubber leveling rollers movably connected to the right side of the front end of the vertical plate, the filter bag moves on the opposite surfaces of the two rubber leveling rollers, a cutter movably connected to the lower side of the front end of the vertical plate, an electric push rod fixedly installed on the rear end of the vertical plate, the electric push rod and the cutter are fixedly connected, an adjustment mechanism is arranged on the right side of the upper end of the base, and two clamping plates are threadedly connected to the front of the adjustment mechanism.
[0008] The present invention is further configured as follows: the front end of the vertical plate is movably connected to two rotating rods, the rear end of the right rotating rod is fixedly installed with a motor, the rear parts of the two rotating rods are fixedly installed with a gear, and the rotating rod and the rubber leveling roller are fixedly connected and interlaced.
[0009] The present invention is further configured as follows: the adjustment mechanism includes a cylinder, a movable concave plate is fixedly installed on the output end of the cylinder, a servo motor is fixedly installed on the right end of the movable concave plate, a forward and reverse threaded rod is fixedly installed on the output end of the servo motor, the forward and reverse threaded rod is movably connected in the movable concave plate, the cylinder is fixedly connected to the lower end of the base, and the clamp is threadedly connected to the forward and reverse threaded rod.
[0010] The present invention is further configured as follows: four cushion blocks are fixedly mounted on the lower end of the base.
[0011] The present invention is further configured such that: the filter bag is located at opposite surfaces of the two clamping plates.
[0012] The present invention is further configured as follows: the cutter and the filter bag are arranged in a cross shape.
[0013] The present invention is further configured such that: the adjustment mechanism is located below the cutter.
[0014] In summary, the present invention has the following beneficial effects:
[0015] 1. When the filter bag passes through two rubber leveling rollers rotating in opposite directions, friction will be generated between the rollers and the filter bag. This friction helps to flatten the wrinkles or uneven parts on the filter bag surface. The rotation of the rubber leveling roller not only generates friction, but also slightly stretches and compresses the filter bag. This alternating action of stretching and compressing helps to further eliminate the wrinkles on the filter bag surface. The surface of the filter bag after leveling is smoother, which helps the cutting tool to fit the edge of the filter bag more accurately, thereby improving the cutting accuracy.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] The present invention is described in detail below in conjunction with the accompanying drawings.
[0025] A coffee filter bag cutting device, such as Figures 1 to 4As shown, it includes a base 1, a vertical plate 2 is fixedly installed on the rear side of the upper end of the base 1, a discharge roller 3 is movably connected to the left side of the front end of the vertical plate 2, a filter bag 4 is movably connected to the discharge roller 3, the filter bag 4 is located at the opposite surface of two clamping plates 9, two rubber leveling rollers 5 are movably connected to the right side of the front end of the vertical plate 2, the filter bag 4 moves on the opposite surface of the two rubber leveling rollers 5, a cutter 6 is movably connected to the lower side of the front end of the vertical plate 2, the cutter 6 and the filter bag 4 are arranged in a cross shape, an electric push rod 7 is fixedly installed on the rear end of the vertical plate 2, the electric push rod 7 and the cutter 6 are fixedly connected, an adjustment mechanism 8 is arranged on the right side of the upper end of the base 1, and the front part of the adjustment mechanism 8 is threadedly connected to two clamping plates 9, when the filter bag 4 passes through two rubber leveling rollers 5 rotating in opposite directions, friction will be generated between the roller and the filter bag 4. This friction helps to flatten the wrinkles or uneven parts on the surface of the filter bag 4, and the rotation of the rubber leveling roller 5 will not only generate friction, but also slightly stretch and compress the filter bag 4. The alternating action of stretching and compression helps to further eliminate the wrinkles on the surface of the filter bag 4. The surface of the filter bag 4 after leveling is smoother, which helps the cutting tool to fit the edge of the filter bag 4 more accurately, thereby improving the cutting accuracy. The two clamping plates 9 clamp and fix the lower part of the filter bag 4 to ensure the stability of the filter bag 4 during cutting and prevent the filter bag 4 from shifting. The electric push rod 7 is an electric drive device that converts the rotary motion of the motor into the linear reciprocating motion of the push rod. Its working principle is that the motor drives a pair of screw nuts after the gear or worm gear is reduced to convert the rotary motion of the motor into linear motion. The forward and backward movements of the electric push rod 7 can be completed by the forward and reverse rotation of the motor. The electric push rod 7 pushes the cutter 6 forward. When the cutter 6 advances to the position of contacting the coffee filter bag 4, the cutter starts to cut the coffee filter bag 4. Since the electric push rod 7 has sufficient thrust and speed, it can ensure that the cutter can smoothly cut the coffee filter bag 4.
[0026] The front end of the vertical plate 2 is movably connected to two rotating rods 10, and the rear end of the right rotating rod 10 is fixedly installed with a motor 11. The rear parts of the two rotating rods 10 are fixedly installed with a gear 12. The rotating rod 10 and the rubber leveling roller 5 are fixedly connected and inserted. The rotating rod 10 is driven to rotate by the motor 11, thereby driving the two meshing gears 12 to rotate. At this time, the two rubber leveling rollers 5 rotate in opposite directions. When the filter bag 4 passes through the two rubber leveling rollers 5 rotating in opposite directions, friction will be generated between the roller and the filter bag 4.
[0027] like Figure 4As shown, the adjustment mechanism 8 includes a cylinder 81, an output end of the cylinder 81 is fixedly installed with a movable concave plate 82, the right end of the movable concave plate 82 is fixedly installed with a servo motor 83, and an output end of the servo motor 83 is fixedly installed with a positive and negative threaded rod 84, the positive and negative threaded rod 84 is movably connected in the movable concave plate 82, the cylinder 81 is fixedly connected to the lower end of the base 1, and the clamping plate 9 is threadedly connected to the positive and negative threaded rod 84. When the filter bag 4 is discharged to between the two clamping plates 9, the movable concave plate 82 is driven to move up or down by starting the cylinder 81, so that the clamping plate 9 can better clamp and position the filter bag 4, and the positive and negative threaded rod 84 is driven to rotate by the servo motor 83. Since the left and right ends of the positive and negative threaded rod 84 have threads of different rotation directions, the nuts or clamping plates 9 with nuts arranged at both ends of the positive and negative threaded rod 84 can move relative to each other, and the two clamping plates 9 clamp and fix the lower part of the filter bag 4 to ensure the stability of the filter bag 4 during cutting and prevent the filter bag 4 from shifting in position.
[0028] Four cushion blocks 13 are fixedly mounted on the lower end of the base 1 , and the cushion blocks 13 provide support and stability to the base 1 .
[0029] Working principle: The filter bag 4 is discharged when the discharge roller 3 rotates. At this time, the filter bag 4 passes through two rubber leveling rollers 5, and the motor 11 drives the rotating rod 10 to rotate, thereby driving the two meshing gears 12 to rotate. At this time, the two rubber leveling rollers 5 rotate in opposite directions. When the filter bag 4 passes through the two rubber leveling rollers 5 rotating in opposite directions, friction will be generated between the rollers and the filter bag 4. This friction helps to flatten the wrinkles or uneven parts on the surface of the filter bag 4. The rotation of the rubber leveling roller 5 not only generates friction, but also slightly stretches and compresses the filter bag 4. The alternating action of stretching and compression helps to further eliminate the wrinkles on the surface of the filter bag 4. The surface of the filter bag 4 after leveling is smoother, which helps the cutting tool to fit the edge of the filter bag 4 more accurately, thereby improving the cutting accuracy. When the filter bag 4 is discharged between the two clamping plates 9, the movable concave plate 82 is driven upward or downward by starting the cylinder 81, so that the clamping plate 9 can better clamp and position the filter bag 4. The positive and negative threaded rod 84 is driven to rotate by the servo motor 83. Since the left and right ends of the positive and negative threaded rod 84 have threads with different rotation directions, the nuts or clamping plates 9 with nuts provided at both ends of the positive and negative threaded rod 84 can move relatively. The two clamping plates 9 clamp and fix the lower part of the filter bag 4 to ensure the stability of the filter bag 4 during cutting and prevent the filter bag 4 from shifting. The electric push rod 7 is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. Its working principle is that the motor drives a pair of screw nuts after being reduced by a gear or a worm gear to convert the rotational motion of the motor into linear motion. The forward and backward movements of the electric push rod 7 can be completed by the forward and reverse rotation of the motor, and the cutter 6 is pushed forward by the electric push rod 7. When the cutter 6 moves forward to the position in contact with the coffee filter bag 4, the cutter starts to cut the coffee filter bag 4. Since the electric push rod 7 has sufficient thrust and speed, it can ensure that the cutter can cut the coffee filter bag 4 smoothly.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
