Description

A cutting device for flat-mouth food bags Technical Field

[0001] This utility model relates to the field of bag cutting technology, and in particular to a cutting device for flat-mouth food bags. Background Technology

[0002] In the food packaging industry, slitting equipment is an indispensable key piece of equipment, mainly used to process rolls or formed plastic films, composite materials, etc. into flat-mouth food bags of specific sizes. Existing flat-mouth food bags mostly use thermoplastic materials such as polyethylene (PE) and polypropylene (PP) as raw materials. Due to the lightweight and soft characteristics of these materials, they often become quite scattered after being cut by a hot cutter, making it difficult to arrange them neatly. This not only increases the workload of subsequent sorting but also increases the cost of the entire packaging process.

[0003] While current cutting devices on the market can control the cutting accuracy of flat-mouth food bags to a certain extent, the lack of effective guidance and collection structures makes it difficult for these freshly cut flat-mouth food bags to maintain their original arrangement and neatness during feeding and discharging. This situation not only affects the efficiency of subsequent processing, but also makes it impossible to effectively guarantee the neatness of the products, further increasing the problems and costs in the production process. Therefore, we propose a cutting device for flat-mouth food bags. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by improving the guiding (before and after cutting) and collecting structure of the roll material based on a hot cutting blade, thereby ensuring the neatness of the product and facilitating subsequent processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cutting device for flat-mouth food bags includes a cutting frame, a cutting table on one side of the cutting frame, a discharge tilting frame facing the other side of the cutting table, and a lifting receiving platform on the outside of the discharge tilting frame.

[0007] A feeding roller is installed above the cutting table between the slitting frames, and an auxiliary roller is installed on the top of the cutting table corresponding to the feeding roller.

[0008] A hot cutting mechanism is installed on the side of the feeding roller near the discharge tilting frame;

[0009] The lifting receiving platform is driven to rise and fall by a telescopic mechanism installed above the slitting frame. A baffle plate is provided on the top of the lifting receiving platform away from the discharge tilting frame. Discharge limiting plates are installed on the inner walls of both sides of the slitting frame above the lifting receiving platform and the discharge tilting frame.

[0010] Furthermore, the cutting table near the end of the feeding roller corresponds to the food bag roll feeding device.

[0011] Furthermore, the tilt angle of the discharge tilting frame is 30°-45°, and the maximum height of the lifting receiving platform is lower than that of the discharge tilting frame.

[0012] Furthermore, a rubber gasket is fitted around the feed roller, and the installation distance between the feed roller and the auxiliary roller is 5μm-60μm, which is used to extrude and guide the PP / PE material roll through.

[0013] Furthermore, the hot cutting mechanism includes a hot cutting blade and a lifting cylinder. The lifting cylinder is mounted on the cutting blade bracket, and the output end is fixedly connected to the hot cutting blade. The hot cutting blade is driven to rise and fall by the lifting cylinder to cut the roll material. The top of the cutting table is provided with a matching cut corresponding to the hot cutting blade.

[0014] Furthermore, the telescopic mechanism includes connecting brackets installed between the slitting frames. There are two connecting brackets, with first cylinders installed on both sides of the top end. The output end of the first cylinder corresponds to the corner of the lifting receiving platform and is fixedly connected to it.

[0015] Furthermore, the baffle plate is installed at the output end of the second cylinder, which is installed at the top of the lifting receiving platform with its output end facing the discharge tilting frame.

[0016] Furthermore, the discharge limiting plate is installed at the output end of the third cylinder, and the third cylinder is installed on both sides of the outer wall of the cutting frame with the output end facing inward. The discharge limiting plate is provided with an expansion part near the discharge tilting frame end, and the bottom of the expansion part is designed to be inclined and parallel to the discharge tilting frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model effectively solves the problem of scattered arrangement after cutting flat-mouth food bags in the prior art through the following design, and has significant beneficial effects:

[0019] 1. By setting up feeding rollers and auxiliary rollers above the cutting table and using rubber gaskets, stable extrusion and guidance of PP / PE roll material are achieved, ensuring smooth conveying of the roll material before and after cutting and reducing the scattering caused by the softness of the material.

[0020] 2. The design of the discharge tilting frame (tilt angle of 30°-45°) allows the cut flat-mouthed food bags to slide down naturally, reducing manual intervention and improving discharge efficiency.

[0021] 3. The lifting receiving platform is raised and lowered through a telescopic mechanism (including connecting bracket and first cylinder). When the cut sheet is higher than the discharge tilting frame, the receiving height is adjusted (lowered) to ensure that the sheet can be stacked on the receiving platform.

[0022] 4. The baffle plate is controlled by the second cylinder and can extend in time during the receiving process to prevent the cut sheet from slipping off the receiving table. It can also be limited according to the required size to further ensure the neatness of the product.

[0023] 5. The discharge limiting plate is controlled by a third cylinder. It can limit and organize the flat-mouth food bag during the discharge process, and can also limit the size according to the requirements. The design of its expansion part allows the limiting plate to better adapt to the angle of the discharge tilting frame, guide the cut sheet to slide out, and improve the limiting effect.

[0024] In summary, the slitting device of this invention ensures that the cut flat-mouth food bags remain neatly arranged, reducing the workload of subsequent processing and improving the efficiency of the entire packaging process. By reducing manual intervention and subsequent processing, the slitting device of this invention helps to reduce production costs and improve economic efficiency. Through improvements to the guiding, cutting, discharging, and collecting structures of the roll material, the invention effectively solves the problems existing in the prior art, improves the slitting efficiency and product quality of flat-mouth food bags, and reduces production costs.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0035] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model will be given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example 1

[0038] As shown in Figures 1-4, this utility model provides a technical solution: a cutting device for flat-mouth food bags, including a cutting frame 1, a cutting table 2 on one side of the cutting frame 1, a discharge tilting frame 21 facing the other side of the cutting table 2, and a lifting receiving platform 3 on the outside of the discharge tilting frame 21.

[0039] A feeding roller 22 is installed above the cutting table 2 between the slitting frames 1, and an auxiliary roller 23 is installed on the top of the cutting table 2 corresponding to the feeding roller 22. The cooperation between the feeding roller 22 and the auxiliary roller 23 can ensure that the roll material maintains a stable tension before entering the cutting area, and prevent the roll material from shifting or wrinkling during the cutting process.

[0040] A hot cutting mechanism 4 is installed on the side of the feeding roller 22 near the discharge tilting frame 21; the hot cutting mechanism 4 is used to precisely cut the roll material to form a flat-mouth food bag of the required size.

[0041] The lifting receiving platform 3 is driven to rise and fall by the telescopic mechanism 5 installed above the cutting frame 1. A baffle plate 31 is provided on the top of the lifting receiving platform 3 away from the discharge tilting frame 21. Discharge limiting plates 32 are installed on the inner walls of both sides of the cutting frame 1 above the lifting receiving platform 3 and the discharge tilting frame 21. The design of the lifting receiving platform 3 allows the cut flat-mouth food bags to be neatly stacked together, facilitating subsequent processing and transportation. The baffle plate 31 and the discharge limiting plate 32 ensure the neatness of the flat-mouth food bags during the receiving and discharging process. Example 2

[0042] As shown in Figure 1-4, the cutting table 2 is connected to the feeding device: the end of the cutting table 2 near the feeding roller 22 corresponds to the food bag roll feeding device, ensuring that the roll can smoothly enter the slitting device for cutting. It is also generally used in conjunction with other conveying mechanisms (such as multiple sets of feeding rollers 22) for roll conveying.

[0043] Regarding the design of the discharge tilting frame 21: the tilting angle of the discharge tilting frame 21 is 30°-45°. This design allows the cut flat-mouth food bags to slide naturally onto the lifting receiving platform 3 by their own weight, reducing manual intervention and the complexity of the mechanical structure. At the same time, the maximum height of the lifting receiving platform 3 is lower than that of the discharge tilting frame 21, ensuring that the flat-mouth food bags can slide smoothly and be stacked on the receiving platform.

[0044] The feeding roller 22 and the auxiliary roller 23 are matched: the feeding roller 22 is fitted with a rubber gasket 221, which increases the friction between the feeding roller 22 and the roll material and prevents the roll material from slipping during the conveying process. The installation distance between the feeding roller 22 and the auxiliary roller 23 is 5μm-60μm. This precise distance design can ensure stable extrusion and guidance of PP / PE roll material, so that it remains flat and under tension.

[0045] It should be noted that the installation distance between the feeding roller 22 and the auxiliary roller 23 varies with the thickness of the PP / PE material roll (the thickness range of PE material flat-mouth food bags is 15~120 micrometers; the thickness range of PP material flat-mouth food bags is 20~100 micrometers). For example, when the roll thickness is 20μm, the installation distance between the feeding roller 22 and the auxiliary roller 23 is 10μm; when the roll thickness is 120μm, the installation distance between the feeding roller 22 and the auxiliary roller 23 is 60μm.

[0046] Working principle of hot cutting mechanism 4: Hot cutting mechanism 4 includes hot cutting blade 41 and lifting cylinder 42. Lifting cylinder 42 is installed on the cutter bracket and the output end is fixedly connected to hot cutting blade 41. Driven by lifting cylinder 42, hot cutting blade 41 can move up and down to cut the roll material. The top of cutting table 2 is provided with matching cut 43 corresponding to hot cutting blade 41 to ensure the accuracy and efficiency of cutting.

[0047] Composition and function of telescopic mechanism 5: Telescopic mechanism 5 includes connecting brackets 51 installed between the cutting racks 1. There are two connecting brackets 51, and first cylinders 52 are installed on both sides of the top. The output end of the first cylinder 52 corresponds to the corner of the lifting receiving platform 3 and is fixedly connected to it. Through the telescopic movement of the first cylinder 52, the lifting receiving platform 3 can be driven to lift and adjust to adapt to the stacking requirements of flat-mouth food bags of different sizes and quantities.

[0048] Adjustment mechanism of baffle plate 31 and discharge limit plate 32: baffle plate 31 is installed at the output end of second cylinder 311, which is installed at the top of lifting receiving platform 3 with its output end facing the discharge tilting frame 21. Through the extension and retraction movement of second cylinder 311, the extension and retraction of baffle plate 31 can be controlled, thereby controlling the size of the receiving material and preventing flat-mouth food bags from slipping off the receiving platform during the receiving process;

[0049] The discharge limiting plate 32 is installed at the output end of the third cylinder 321. The third cylinder 321 is installed on the outer walls of both sides of the cutting frame 1 with the output end facing inward. The discharge limiting plate 32 is provided with an expansion part 322 at the end near the discharge tilting frame 21. The bottom of the expansion part 322 is inclined and parallel to the discharge tilting frame 21. By the extension and retraction movement of the third cylinder 321, the spacing of the discharge limiting plate 32 can be adjusted to control the size of the two sides of the receiving material, ensuring the neatness and stability of the flat-mouth food bag during the discharge process.

[0050] Workflow: When using a flat-mouth food bag slitting device, the food bag roll is first installed on the feeding device. Under the compression and guidance of the feeding roller 22 and auxiliary roller 23, the roll enters the cutting area. The hot cutting mechanism 4 cuts the roll to form flat-mouth food bags of the required size. The cut flat-mouth food bags slide down onto the lifting receiving platform 3 through the discharge tilting frame 21. The lifting receiving platform 3 adjusts its height as needed to ensure that the flat-mouth food bags can be neatly stacked together. During the receiving process, the baffle plate 31 and the discharge limiting plate 32 respectively play the roles of preventing the flat-mouth food bags from slipping and organizing the discharge. Finally, when the number of flat-mouth food bags on the lifting receiving platform 3 reaches a certain number or when the discharge tilting frame 21 can no longer lower its height, they can be removed for subsequent processing and transportation.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
