Description

Technical Field

[0001] This invention belongs to the field of candy packaging technology and relates to a cutting device for candy packaging paper. Background Technology

[0002] Candy is a type of confectionery, referring to a snack whose main ingredient is sugar. After production, candy needs to be packaged in wrapping paper for storage and transportation. In other words, finished candy generally consists of raw sugar and wrapping paper, the ends of which are usually twisted to tightly enclose the sugar.

[0003] In existing technologies, the raw material for candy packaging paper is pre-produced rolls of strip packaging paper. To meet the packaging needs of candies of different sizes and types, the candy packaging paper needs to be cut, that is, the packaging paper roll needs to be cut to a certain length to form packaging paper of the corresponding length for later packaging of candies. For example, Chinese patent document CN210884583U discloses a multi-functional intelligent slitting machine for candy packaging, including a base, a support plate fixedly installed at one end of the top of the base, a guide rod fixedly installed on the top of one side of the support plate, a packaging strip roll set outside the guide rod, the packaging strip roll being rotatably connected to the guide rod, and a conveying slitting mechanism and a strip roll pressing mechanism set at the top of the base. The conveying slitting mechanism includes two conveying rollers and two pressure rollers. This slitting machine, by installing two sets of pressure rollers and conveying rollers at the top of the base, causes the packaging strip to move under the pressing motion of the two sets of pressure rollers and conveying rollers, and controls the hydraulic rod to drive the upper cutter holder to descend, thereby cutting the packaging strip to obtain long strips of single-piece packaging paper.

[0004] With advancements in candy packaging technology, candy manufacturers, in order to meet customers' demands for convenient unpacking, not only need to cut the packaging paper rolls to a fixed length but also need to leave a tear slit along the middle edge of the rectangular sheet of packaging paper. Current candy packaging machines typically require two cutting steps when cutting this type of packaging paper with a tear slit. The first step is fixed-length cutting, where a roll of packaging paper is cut into a fixed-length sheet using a slitting machine. The second step is to cut another tear slit using a separate cutting mechanism before or after sealing the candy. The connection and transport between the first and second steps takes time; that is, it takes time to move the packaging paper from the fixed-length slitting machine to the tear slit cutting mechanism. This results in low overall cutting efficiency of the candy packaging paper per unit time, thus affecting the overall packaging efficiency. Therefore, in order to improve cutting efficiency, those skilled in the art commonly use a technical means to transport pre-cut and ready-to-be-cut packaging paper by selecting a faster and more efficient transport device, thereby saving transport time and improving cutting efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a cutting device for candy wrapping paper. The technical problem to be solved by this invention is how to improve the cutting efficiency of tear-resistant candy wrapping paper.

[0006] The objective of this invention can be achieved through the following technical solution: a candy wrapping paper cutting device, comprising a frame and a feeding table fixed to the frame for conveying candy wrapping paper, the feeding table being elongated with an infeed end and an outfeed end at its two ends, respectively, and the frame being provided with a cutter for fixed-length cutting, characterized in that the cutter is located on the front side of the feeding table and close to the outfeed end, a clearance opening is provided in the middle of the feeding table between the outfeed end and the infeed end, and a cutter for cutting tear seams is provided on the inner side of the feeding table, the cutter being able to extend out of the table surface of the feeding table through the clearance opening.

[0007] Unlike existing technologies, this invention redesigns the entire candy wrapper cutting device. By utilizing the feeding platform itself as a platform for normal wrapper transport, the cutting blades for fixed-length slitting and tear cutting are cleverly arranged around the perimeter of the feeding platform, thereby improving cutting efficiency. Specifically, existing feeding platforms are elongated with an inlet and an outlet, respectively. During wrapper transport, the wrapper enters from the inlet and exits from the outlet. By placing the fixed-length slitting blade near the outlet, and providing a clearance opening in the middle of the feeding platform between the inlet and outlet, and then placing the tear cutting blade on the inner side of the feeding platform, the cutting efficiency is improved when the wrapper roll enters from the inlet and passes through the clearance opening. At this time, the cutting blade can pass through the aforementioned clearance opening and extend onto the conveyor table to perform a tearing operation on the passing strip of packaging paper. Subsequently, the packaging paper with the tear continues to be conveyed forward until it reaches the output end and the cutting blade's station. At this time, the cutting blade located on one side of the output end performs a fixed-length slit cut on the packaging paper, with the slit position exactly at the middle of the tear, thus completing the processing of the packaging paper and obtaining a piece of packaging paper with tear seams on both sides. In other words, through the above integrated layout design of the cutting blade and the cutting blade position around the conveyor table, the packaging paper can directly utilize its own conveying process to complete both the fixed-length slit cut and the tearing process within its own conveying process. This is equivalent to completely eliminating the extra connection and transfer process from one cutting mechanism to another, and eliminating the waste of transfer time, thereby greatly improving the cutting efficiency of tear-sealed candy packaging paper.

[0008] In the aforementioned candy wrapper cutting device, the cutter includes a cutter shaft rotatably connected to a frame and a cutter head fixed to the frame. The axis of the cutter shaft is arranged along the width of the feed table. A horizontal blade capable of swinging relative to the cutter head is fixed on the cutter shaft. The cutter shaft also has a strip-shaped channel arranged along the width of the feed table. The rear opening of the strip-shaped channel faces the paper output end, and the front opening faces upwards towards the cutter head. On the one hand, the cutter structure design of the aforementioned swinging horizontal blade cooperating with the cutter head allows for fixed-length cutting of the wrapper with just a small swing, resulting in faster cutting speed and higher efficiency. On the other hand, the design of the strip-shaped channel, with its rear opening facing the paper output end and its front opening facing upwards towards the cutter head, ensures that the wrapper, after exiting the paper output end, can be accurately guided by the strip-shaped channel to the cutter head for cutting. This reduces the likelihood of paper jams and machine stoppages during the cutting process, thereby improving the cutting efficiency of tear-resistant candy wrapper. In addition, the aforementioned strip channel design can guide the packaging paper, making the cut edges of the packaging paper more accurate and regular, thereby improving the cutting accuracy and quality of tear-resistant candy packaging paper.

[0009] In the aforementioned candy wrapper cutting device, two drive rollers for feeding the wrapper are provided between the paper output end of the feeding table and the cutter. A conveying port connected to the paper output end is formed between the two drive rollers. A transition guide plate is provided between the conveying port and the strip channel to guide the wrapper from the conveying port to the strip channel. The transition guide plate is fixed to the frame. Under the drag of the drive rollers, the wrapper is pulled out from the paper output end, then passes through the conveying port, and is smoothly conveyed into the strip channel under the guidance of the transition guide plate. This further ensures that the wrapper will not jam and stop the machine, thereby improving the cutting efficiency of tear-resistant candy wrapper.

[0010] In the aforementioned candy wrapper cutting device, a damping plate parallel to the cross blade is fixed on the cutter shaft. The inner surface of the damping plate is an uneven damping surface, and the strip channel is formed between the damping plate and the cross blade. When the cutter cuts the wrapper by oscillation, the damping plate provides resistance to the wrapper, preventing it from slipping out of the strip channel during oscillation, thus ensuring the accuracy of fixed-length cutting. Furthermore, the damping surface also prevents the end of the wrapper from slipping out of the strip channel, causing paper jams and machine stoppages, thereby improving the cutting efficiency of tear-resistant candy wrapper.

[0011] In the aforementioned candy wrapper cutting device, the cutter is rotatably connected to the frame with its axis arranged along the width of the feeding table. A drive unit is also fixedly connected to the frame. The drive unit has a rotatable drive shaft, and a transmission mechanism is provided between the free end of the drive shaft and the cutter. This transmission mechanism converts the rotational motion of the drive shaft into the linear reciprocating motion of the cutter. A linkage rod is provided between the free end of the drive shaft and the rotating cutter, converting the rotational motion of the drive shaft into the reciprocating oscillating motion of the cutter. The drive unit, through the aforementioned transmission mechanism and linkage rod, can drive the cutter and the cutter to perform cutting actions synchronously. This design allows the cutter and the cutter to complete the cutting action synchronously, effectively reducing the two-step cutting process of tear-resistant wrapper to a single step, thus significantly shortening the cutting time and greatly improving the cutting efficiency of tear-resistant candy wrapper. Furthermore, the fact that the cutter and the cutter are driven by a single drive unit simplifies the structure of the cutting device, improves its compactness, and also helps save costs.

[0012] In the aforementioned candy wrapper cutting device, the rear end of the linkage rod is hinged to the drive shaft, forming a hinge center point one. The front end of the linkage rod is hinged to the cutter shaft, forming a hinge center point two. The distance from hinge center point one to the drive shaft axis is less than the distance from hinge center point two to the cutter shaft axis. Through this design, the linkage rod can convert the rotational motion of the drive shaft into the reciprocating oscillating motion of the cutter. That is, the rear end of the linkage rod rotates around the drive shaft axis under the drive of the drive shaft. Since the distance from hinge center point one to the drive shaft axis is less than the distance from hinge center point two to the cutter shaft axis, the front end of the linkage rod will extend and retract back and forth. Therefore, the cutter shaft, driven by the linkage rod, can cause the cutter to oscillate back and forth.

[0013] In the aforementioned candy wrapper cutting device, the transmission mechanism includes a transmission shaft one and a transmission shaft two rotatably connected to the frame. The transmission shaft one is connected to the drive shaft via a chain, belt, or gear. An eccentric wheel is fixed on the transmission shaft one, and a crank one and a crank two are fixed on the transmission shaft two. A transmission rod is provided between the crank one and the eccentric wheel. One end of the transmission rod is sleeved on the eccentric wheel and can rotate circumferentially relative to the eccentric wheel. The other end of the transmission rod is hinged to the crank one. The transmission mechanism also includes a guide seat fixed to the frame. A sliding rod that can slide and extend in a direction perpendicular to the feed table surface is slidably connected to the guide seat. The cutting blade is fixed to the upper end of the sliding rod. A hinge block is provided between the lower end of the sliding rod and the crank two. The two ends of the hinge block are respectively hinged to the sliding rod and the crank two. Through the above design, the rotational motion of the drive shaft can be converted into the linear reciprocating motion of the cutting blade. The specific working process is as follows: When the drive shaft rotates, it will drive the transmission shaft one to rotate. At this time, the eccentric wheel fixed on the transmission shaft one will also rotate. Then, the transmission rod will swing back and forth under the drive of the eccentric wheel. Then, the crank one will swing back and forth slightly under the drive of the transmission rod. The crank two will also swing back and forth slightly. Since the slide rod is linked to the crank two through the hinge block, the slide rod will then slide back and forth in a direction perpendicular to the feed table surface under the guidance of the guide seat. Finally, the cutting blade can achieve linear reciprocating motion, thereby achieving the cutting of the tear seam.

[0014] As an alternative, the transmission mechanism includes a drive shaft rotatably connected to the frame and a fixed base fixed to the frame. A guide rod, capable of sliding and extending perpendicular to the feed table surface, is slidably connected to the fixed base. The cutting blade is fixed to the upper end of the guide rod. The drive shaft is connected to the drive shaft via a chain, belt, or gear transmission, and its axis is coplanar with the axis of the guide rod. A cam is fixed to the drive shaft. A roller bracket is fixed to the lower end of the guide rod, and a roller is rotatably connected to the roller bracket. A spring is also fitted to the lower end of the guide rod. One end of the spring abuts against the fixed base, and the other end abuts against the roller bracket. The roller, under the action of the spring, presses against the outer circumferential surface of the cam and can roll along the outer circumferential surface of the cam. With this solution, the rotational motion of the drive shaft can also be converted into the linear reciprocating motion of the cutting blade. Specifically, the drive shaft rotates the transmission shaft, which in turn rotates the cam. The rotation of the cam causes the roller to reciprocate linearly, which in turn drives the guide rod to reciprocate and extend along a direction perpendicular to the material feeding table. Ultimately, this enables the cutting blade to achieve linear reciprocating motion, thereby cutting the tear seam.

[0015] In the aforementioned candy wrapper cutting device, a strip-shaped adjusting seat arranged along the length of the conveyor table is fixed to the upper end of the slide rod. The blade holder of the cutter can slide along the adjusting seat and be locked and fixed to the adjusting seat with bolts. This design allows for flexible adjustment of the cutter position, making the device suitable for cutting wrapper paper of different sizes, thus improving its versatility.

[0016] In the aforementioned candy wrapper cutting device, a connecting block is fixedly connected to the free end of the drive shaft. An adjustment groove is provided on the connecting block, and an adjustment block capable of sliding along the groove is located within the groove. The adjustment block has a waist-shaped hole and a hinge hole. A screw passes through the waist-shaped hole to fix the adjustment block within the groove. The hinge hole is offset from the axis of the drive shaft, and the linkage rod is hinged to the adjustment block through this hinge hole. With this design, when the screw in the waist-shaped hole of the adjustment block is unscrewed, the adjustment block can slide along the adjustment groove to adjust the eccentricity between the hinge hole and the axis of the drive shaft. This allows for fine-tuning of the cutter's swing amplitude, thereby enabling fine-tuning of the cutting synchronization between the cutter and the trimmer, ensuring they achieve synchronization and improving the cutting efficiency of the device. Furthermore, this design makes the device's debugging more convenient.

[0017] In the aforementioned candy wrapper cutting device, a locking block one and a locking block two are provided outside the cutter shaft. Locking block one and locking block two are connected to each other by bolts and clamped and fixed to the cutter shaft. The linkage rod is hinged to either locking block one or locking block two. Through this design, when the bolts are loosened, locking block one and locking block two can rotate relative to the cutter shaft. This allows for fine-tuning of the linkage rod's hinge point, thereby fine-tuning the cutter's swing amplitude. This, in turn, allows for fine-tuning of the cutting synchronization between the cutter and the cutting blade, ensuring they achieve synchronization and thus improving the cutting efficiency of the device. Furthermore, this design makes the device's debugging more convenient.

[0018] In the aforementioned candy wrapper cutting device, the linkage rod includes a rod body and two adjusting rods, one threadedly connected to both ends of the rod body. Adjusting rod one is eccentrically hinged to the drive shaft, forming a hinge center point one. Adjusting rod two is eccentrically hinged to the cutter shaft, forming a hinge center point two. This design allows the actual length of the linkage rod to be adjusted as needed, enabling fine-tuning of the cutter's swing amplitude. This, in turn, allows for fine-tuning of the cutting synchronization between the cutter and the cutting blade, ensuring they achieve synchronization and thus improving the cutting efficiency of the device. Furthermore, this design makes the device's debugging more convenient.

[0019] Compared with existing technologies, this candy wrapper cutting device has the following advantages:

[0020] 1. This cutting device integrates a fixed-length slitting cutter and a cutter for cutting tear seams. Through the ingenious layout design of the two, the packaging paper can complete both fixed-length slitting and tear seam cutting during its own conveying process, with no wasted transfer time between the two processes. Furthermore, this device can simultaneously realize fixed-length slitting and tear seam cutting of tear-sealed packaging paper, which is equivalent to turning two processes into one, greatly improving the cutting efficiency of tear-sealed candy packaging paper.

[0021] 2. This device has a simple and compact structure, low manufacturing cost, convenient debugging, high cutting accuracy, and good versatility. Attached Figure Description

[0036] This device can efficiently cut and process candy wrapper rolls into shapes such as... Figure 6 The processing procedure for the sheet-shaped tear-sealed candy wrapper shown is as follows: First, the candy wrapper roll is pulled out and fed into the paper inlet 2a of the feeding table 2, passing through the pressure roller 15 and into the conveying port 5a of the drive roller 5. After installation, the candy wrapper strip to be cut can move along the feeding table 2 under the drag of the drive roller 5. During this movement, the cutter 4 and the cutting blade 3 can perform cutting actions synchronously. During the first cut, the cutting blade 3 will cut off the paper end. As the wrapper strip continues to move forward, when the wrapper strip with tear seams reaches the preset position, the cutter 4 and the cutting blade 3 will perform cutting actions synchronously again. At this time, the cutting position of the cutting blade 3 is exactly in the middle of the tear seam of the wrapper strip, thus completing the cutting of the first sheet of finished tear-sealed candy wrapper. The cutting work is repeated in this way to obtain sheet after sheet of finished tear-sealed candy wrapper.
