Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a foreign object removal device for the heating block of a packaging machine. Background Technology

[0002] In food processing, food packaging bags need to be sealed after food is contained. This process uses a packaging machine, which utilizes a heating block to heat the bag and cut it with a toothed blade. However, after prolonged use, the heating block accumulates excessive plastic impurities and other foreign matter, leading to incomplete sealing and incomplete cutting of the packaging bags. Therefore, it is necessary to clean the foreign matter remaining on the heating block. While it's generally inconvenient to stop the machine during cleaning to avoid affecting production efficiency, the continuous heating of the heating block can easily cause burns to personnel. Therefore, a dedicated heating block cleaning device is required.

[0003] For example, Chinese utility model patent CN211642719U discloses a food packaging device with an inflation function, relating to the field of food packaging devices. It includes a vacuum chamber with a feed inlet at the top. Inside the vacuum chamber is a toothed blade frame, with a toothed blade on one side of the frame, fixedly connected to the frame. At the bottom of the frame is a heating block frame, with a heating block on one side, also fixedly connected to the frame. A support frame is located at the top of the toothed blades, fixedly connected to the inner wall of the vacuum chamber on both sides. A scraper is located on one side of the support frame, and a slide rail is also provided on the other side, allowing the scraper to slide slidably against the support frame. A cleaning cotton is located on one side of the toothed blades, movably sleeved with them. By controlling the scraper and cleaning cotton to clean the heating block and toothed blades, issues such as incomplete sealing of food packaging bags and difficulty in cutting food packaging are reduced.

[0004] In this solution, a slide rail is installed on one side of the heating block, and a scraper that slides on the slide rail is used to clean the heating block. This solution uses an external cleaning component on the packaging machine for cleaning, which is not suitable for packaging machines where it is not easy to add an external cleaning component. In addition, the heating block is not cleaned frequently, but only after long-term use. The method of fixing the cleaning component on the packaging machine will have a certain impact on the conveying of packaging bags in daily production. Therefore, there is an urgent need for a handheld cleaning device to meet the usage requirements. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a foreign object cleaning device for the heating block of a packaging machine, which solves the problem that the existing cleaning device, which is fixed on the packaging machine, affects daily processing.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 , 2As shown in Embodiment 1, a foreign object removal device for a packaging machine heating block includes a handle 1 for easy gripping during use. A support component 2 is located at the front end of the handle 1, and a scraper structure 3 is adjustablely connected to the front end of the support component 2. The support component provides adjustable support for the scraper structure during use, allowing the orientation of the scraper structure to be changed. During use, the scraper structure is used to scrape away foreign objects from the heating block. A suction tube 4, which cooperates with the scraper structure 3, is provided on the support component 2 and is connected to a suction component 5. The suction component generates negative pressure on the suction tube, thereby sucking away the scraped-off foreign objects. This device is convenient to use and simple to operate, employing manual gripping for foreign object removal, avoiding the need for constantly cleaning related components on the equipment and preventing interference or impact on normal processing.

[0024] Specifically, in this embodiment, the support component 2 includes a support rod 21 connected to the handle 1. The front end of the support rod 21 is hinged to the support base 22 via a hinge shaft 23. A locking structure for locking the hinged posture is provided between the support base 22 and the support rod 21.

[0025] In this embodiment, the locking structure is first unlocked according to the actual usage scenario, and the hinge angle between the support base and the support rod is adjusted to achieve a suitable scraping posture. Then, the locking mechanism is used to lock the hinge posture between the support base and the support rod. Subsequently, the scraper structure is used to scrape off the foreign objects from the heating block, and after scraping, the suction component is used to suck the scraped foreign objects out through the suction tube. This device can be held and used without being fixed to the heating machine, reducing space occupation.

[0026] Example 2, based on Example 1, such as Figure 2 , 3 As shown, the locking structure includes a pair of knobs 24 that are threaded to both ends of the hinge shaft 23. A locking piece 25 is provided between the knobs 24 and the support base 22. The locking piece 25 is provided with locking blocks 26 that cooperate with the support rod 21 and the support base 22 respectively.

[0027] In this embodiment, when the knobs 24 on both sides are tightened, the locking plate 25 achieves a fixed engagement with the support base through the locking block 26, preventing relative movement between the two. Additionally, the locking plate 25 forms two slots for securing the support rod 21 through the locking block 26. These two slots are respectively positioned along the axial direction of the support base and perpendicular to the axial direction, respectively locking the support rod 21 and the support base 22 in coaxial and perpendicular positions. In this embodiment, when a heating machine structure exists above the heating block, to avoid interference and collision during cleaning, the support base and support rod are adjusted to a vertical position to allow for horizontal gripping of the handle to scrape foreign objects from the vertical sidewall of the heating block. In the absence of interference from the heating machine structure, the coaxial arrangement between the support base and support rod directly scrapes away foreign objects, making force application and operation more convenient and flexible.

[0028] In Example 3, based on Example 2, the scraper structure 3 includes a scraper 31 connected to the support base 22. The front end of the scraper 31 is provided with a serrated blade surface 32, which is used to scrape foreign objects off the packaging machine heating block. A collection groove 33 is provided on one side of the scraper 31, and the suction tube 4 is connected to the collection groove 33.

[0029] Specifically, in this embodiment, the gathering groove 33 is an arc-shaped groove, vertically welded and fixed to one side of the scraper 31. A certain distance is maintained between the front end of the gathering groove and the serrated surface of the scraper to prevent the gathering groove from affecting the scraping off of foreign objects.

[0030] As a further specific embodiment, the bottom of the collection groove 33 is provided with an elongated hole 34, and a guide shroud 35 is provided on the outside of the elongated hole 34. The guide shroud 35 is connected to a metal conduit 36, and the metal conduit 36 ​​is connected to a suction tube 4. Foreign objects scraped off or remaining in the collection groove can enter the guide shroud through the elongated hole under the negative pressure generated by the suction component, and be sucked away by the metal conduit and the suction tube.

[0031] In this embodiment, the suction tube 4 is a corrugated metal flexible tube, which can bend according to the angle between the support rod and the support base to meet usage requirements. At the same time, both the suction tube and the metal conduit are made of metal to avoid the heat generated by the heating block affecting use during cleaning without stopping the machine.

[0032] Example 4, based on Example 3, such as Figure 1 , 5 As shown, the suction assembly 5 includes a syringe 51 fixedly attached to the handle 1. One end of the syringe 51 is connected to the suction tube 4, and the other end of the syringe 51 is open. A piston 52 is slidably disposed inside the suction tube 4. The piston 52 is connected to a push rod 53, and a tension spring 54 is provided between the piston 52 and the opening at the other end of the syringe 51. The handle 1 is provided with a locking key for locking and releasing the push rod 53. In this embodiment, before suctioning foreign objects, the push rod is pushed to push the piston to the side close to the suction tube, the gas in the syringe is discharged, and the tension spring is stretched and stored. At this time, the locking key is used to lock the position of the push rod and the piston. After the foreign objects are scraped off, the locking key is used to release the locking of the position of the push rod and the piston. Under the reset action of the tension spring, the piston is pulled to move quickly. At this time, the gas is quickly sucked in through the suction tube, and the foreign objects are simultaneously sucked into the syringe along with the gas.

[0033] Specifically in this embodiment, such as Figure 4 , 5As shown, the locking mechanism includes a slider 55 that slides on the handle 1. A spring 56 is provided between the slider 55 and the handle 1. The slider 55 is connected to both the button and the latch 57. The push rod 53 has a groove for engaging with the latch 57. The button protrudes from the handle 1, which has space to allow the button to move with the slider. When the push rod needs to be locked, the spring is pre-compressed on the slider, and the slider pushes the latch against the side wall of the push rod. At this time, the push rod is pushed, causing it to push the piston to expel internal gas. When the groove aligns with the latch, the spring relaxes, pushing the slider to move. The slider then drives the latch into the groove, thus locking the push rod. When released, pressing or pushing the button causes the slider to move in the opposite direction, compressing the spring and separating the latch from the groove. Under the action of the tension spring, the piston is pulled outward rapidly, generating suction.

[0034] As a further optional implementation, to facilitate the removal of foreign objects from inside the syringe, a retaining ring is threaded onto the open end of the syringe, and a tension spring is fixed on the retaining ring. The foreign object can be removed by unscrewing the retaining ring.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
