Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a heat shrink film cutting device for fresh corn production and packaging. Background Technology

[0002] Fresh corn refers to tender young corn with special flavor and quality, also known as sweet corn. Compared with ordinary corn, it has the characteristics of being sweet, glutinous, tender, and fragrant. In the corn processing process, heat shrink film is needed to package it, but the heat shrink film needs to be cut before packaging.

[0003] For example, a heat shrink film cutting device for fresh corn production and packaging disclosed in Chinese patent literature (publication number: CN218506306U) uses a servo motor to drive a threaded rod to rotate repeatedly in the forward and reverse directions when the cutting blade cuts the material. This causes the slider to drive the cutting blade to move rapidly in a lateral reciprocating motion, enabling it to quickly cut the material upon contact. This effectively ensures the cutting effect and efficiency of the equipment. At the same time, the conveying device can effectively transport the cut product to the next processing step, effectively avoiding the need for manual collection and transportation of the cut product in traditional cutting devices, thus effectively ensuring the equipment's performance.

[0004] This device lacks adaptability to heat shrink film of different thicknesses. The feeding roller cannot be adjusted. When encountering thicker heat shrink film, it misaligns with the feeding roller. When conveying films of different thicknesses, uneven tension is likely to occur, leading to deviations in the cutting position. Uneven force can also cause scratches on the surface of the heat shrink film. Summary of the Invention

[0005] The purpose of this invention is to solve the problem mentioned in the background art that the tension of films of different thicknesses is easily inconsistent when conveying them, and to provide a heat shrink film cutting device for fresh corn production and packaging.

[0006] A heat shrink film cutting device for fresh corn production and packaging includes a machine body. Support blocks are fixedly connected to both sides of the top wall of the machine body. Long grooves are formed on both sides of the support blocks. A cavity is formed inside the support blocks. A first cylinder is provided on the inner bottom wall of the support blocks. A second cylinder is provided inside the two long grooves. A connecting block is fixedly connected to one end of the second cylinder. A tension spring is fixedly connected to the opposite surface of the second cylinder and the first cylinder. A locking component is fixedly connected to the outer wall of the connecting block. A locking groove is formed on the outer wall of the support block. Multiple locking grooves are arranged in a linear array of two in a group. Long blocks are fixedly connected to both sides of the top wall of the machine body. A cleaning component is provided inside the long blocks.

[0007] The cleaning component includes a square groove at the lower end of two long blocks. A fan is installed on the top wall of the machine body. A hinge is fixedly connected to the outer wall of one of the long blocks. A cleaning door is fixedly connected to one side of the hinge. A handle is fixedly connected to the outer wall of the cleaning door.

[0008] The locking assembly includes a long plate, one side of which is fixedly connected to the outer wall of a connecting block. A fixing block is fixedly connected to the outer wall of the long plate. A threaded rod is threadedly connected to the middle of the fixing block. An inclined block is fixedly connected to one end of the threaded rod. A connecting plate is fixedly connected to the outer wall of the long plate. There are two connecting plates. A pressing rod is rotatably connected to the opposite surfaces of the two connecting plates through a bearing. A fixing plate is fixedly connected to one end of the pressing rod. A slot is opened at one end of the pressing rod. A rotating column is rotatably connected inside the slot.

[0009] Both ends of the threaded rod extend to both sides of the fixed block, and a turntable is fixedly connected to one end of the threaded rod.

[0010] Both sides of the bottom wall of the fixed plate are fixedly connected with locking blocks, and the outer wall of the locking blocks is connected to the locking groove.

[0011] The support blocks are provided with feeding rollers on their opposite surfaces. The two ends of one feeding roller are rotatably connected to one end of the second cylinder through bearings, and the two ends of another feeding roller are rotatably connected to one end of the first cylinder through bearings.

[0012] The number of fans is two, and they are located inside one of the square slots, while the cleaning door is located outside the other of the square slots.

[0013] The working principle and process of this utility model:

[0014] The feeding rollers are mounted on opposite surfaces of the support block, with their two ends rotatably connected to the first and second cylinders, respectively. The second cylinder is connected to the first cylinder via a tension spring. When heat-shrinkable films of different thicknesses are placed, the change in film thickness exerts a force on the feeding rollers. The tension springs, being elastic, automatically expand and contract under this force. For example, when the heat-shrinkable film is thicker, the feeding rollers experience an outward force, stretching the tension springs and increasing the distance between the two rollers. Conversely, if the heat-shrinkable film is thinner, the tension springs contract, decreasing the distance between the rollers. This adapts to different film thicknesses, ensuring heat shrinkage during the feeding process. The shrink film is always kept under appropriate tension to avoid being too loose or too tight, which would affect subsequent cutting. The locking assembly is used to fix the position of the feed roller after adjustment. When the turntable is rotated, the threaded rod rotates accordingly. Since the threaded rod is threadedly connected to the fixed block, the inclined block fixed at one end of the threaded rod will move along the axial direction of the threaded rod. Pressing the pressing rod makes it rotate around the connecting plate, and the fixed plate moves accordingly. When the inclined block moves to a certain position, it pushes the rotating column, which drives the fixed plate downward, so that the locking blocks on both sides of the bottom wall of the fixed plate engage with the locking grooves on the outer wall of the support block, thus fixing the position of the feed roller and ensuring that the feed roller works stably during the heat shrink film feeding process.

[0015] Furthermore, during the cutting process, debris from the heat shrink film may fall into the gaps and corners of the device. A cleaning component is installed under the long block. The fan of the cleaning component is installed in a square groove on the top wall of the machine. When the fan is turned on, a strong airflow is generated, which blows the debris into the square groove. If it is necessary to clean the impurities accumulated in the square groove, the cleaning door is opened to clean the impurities inside.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, the feeding roller is installed on the opposite surface of the support block, and its two ends are connected to different cylinders. The cylinders are connected by tension springs. The feeding roller spacing can be automatically adjusted according to the thickness of the heat shrink film to ensure proper tension. The locking assembly is used to fix the position of the adjusted feeding roller. The locking and fixing is achieved by rotating the turntable and pressing the pressing rod.

[0018] 2. In this utility model, heat shrink film debris is prone to fall into the corners of gaps during cutting. The cleaning component under the long block can solve this problem. The fan in the component generates airflow, and the cleaning door can also clean the impurities accumulated inside the component. Attached Figure Description

A pressing rod 16 is rotatably connected to the opposing surfaces of the two connecting plates 15 via bearings. A fixing plate 19 is fixedly connected to one end of the pressing rod 16. A slot 17 is formed at one end of the pressing rod 16. A rotating column 18 is rotatably connected inside the slot 17. Both ends of the threaded rod 12 extend to both sides of the fixing block 11. A turntable 13 is fixedly connected to one end of the threaded rod 12. Both sides of the bottom wall of the fixing plate 19 are fixedly connected to the threaded rod 12. A locking block 20 is fixedly connected, and the outer wall of the locking block 20 engages with the inside of the locking groove 4. Feeding rollers 21 are provided on the opposite surfaces of the support blocks 2. The two ends of one feeding roller 21 are rotatably connected to one end of the second cylinder 7 through bearings, and the two ends of the other feeding roller 21 are rotatably connected to one end of the first cylinder 6 through bearings. The locking assembly is used to fix the feeding rollers 21. Rotating the turntable 13 drives the threaded rod 12 to move the inclined block 14. Pressing the pressing rod 16 rotates around the connecting plate 15, driving the fixed plate 19 to move, so that the locking block 20 engages with the locking groove 4, thus fixing the position of the feeding roller 21. The feeding roller 21 is installed between the support blocks 2, and its two ends are rotatably connected to the first cylinder 6 and the second cylinder 7. The spacing can be adjusted under the action of the tension spring 8.

Turning the handle 205 opens the cleaning door 204, which can clean the impurities accumulated in the square groove 201.

[0030] The working principle and process of this embodiment:

[0031] The feeding roller 21 is mounted on the opposite surface of the support block 2, with its two ends rotatably connected to the first cylinder 6 and the second cylinder 7, respectively. The second cylinder 7 and the first cylinder 6 are connected by a tension spring 8. When heat shrink film of different thicknesses is placed, the change in the thickness of the heat shrink film will exert a force on the feeding roller 21. The tension spring 8 is elastic and will automatically expand and contract under this force. For example, when the heat shrink film is thicker, the feeding roller 21 is subjected to an outward force, the tension spring 8 is stretched, and the distance between the two feeding rollers 21 increases; if the heat shrink film is thinner, the tension spring 8 contracts, and the distance between the feeding rollers 21 decreases. This adapts to heat shrink film of different thicknesses and ensures that the heat shrink film is always in a suitable position during the feeding process. The tension is maintained to prevent it from being too loose or too tight, which could affect subsequent cutting. The locking assembly is used to fix the position of the adjusted feeding roller 21. When the turntable 13 is rotated, the threaded rod 12 rotates accordingly. Since the threaded rod 12 is threadedly connected to the fixing block 11, the inclined block 14 fixed at one end of the threaded rod 12 will move along the axial direction of the threaded rod 12. Pressing the pressing rod 16 makes it rotate around the connecting plate 15, and the fixing plate 19 moves accordingly. When the inclined block 14 moves to a certain position, it pushes the rotating column 18, which drives the fixing plate 19 downward, so that the locking blocks 20 on both sides of the bottom wall of the fixing plate 19 engage with the locking groove 4 on the outer wall of the support block 2, thus fixing the position of the feeding roller 21 and ensuring that the feeding roller 21 works stably during the heat shrink film feeding process.

[0032] Furthermore, during the cutting process, debris from the heat shrink film may fall into the gaps and corners of the device. A cleaning component is installed under the long block 22. The fan 202 of the cleaning component is installed in the square groove 201 on the top wall of the body 1. When the fan 202 is turned on, a strong airflow will be generated to blow the debris into the square groove 201. If it is necessary to clean the impurities accumulated in the square groove 201, the cleaning door 204 is opened to clean the impurities inside.
