Description

Technical Field

[0001] This application relates to the field of tea packaging, and in particular to a pressure-resistant tea packaging device. Background Technology

[0002] Tea generally refers to the product made by picking the leaves or tender buds of the tea tree and then processing them. Tea is rich in catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid. Drinking tea regularly after brewing it can regulate the body and ensure good health. my country has a rich tea culture since ancient times, so the production and consumption of tea has a broad market prospect in my country.

[0003] After tea processing, packaging is necessary to ensure convenient sales and protect the tea. Currently, the most common packaging method is using plastic bags. Further, safety gas is often added to the bags to inflate them. While this method can prevent direct compression damage to the tea, the inflated bags are prone to bursting under pressure. This not only fails to protect the tea from pressure but also risks expelling it during bursting, making it difficult to provide adequate pressure protection after packaging.

[0004] Therefore, a pressure-resistant packaging device for tea is proposed to solve some of the problems existing in the above-mentioned prior art. Summary of the Invention

[0005] The purpose of this application is to improve the compression resistance and protective performance of packaged tea. Compared with the prior art, it provides a compression-resistant packaging device for tea, including a packaging prefabrication machine and a tea filling machine. The packaging prefabrication machine includes a support fixedly installed on the ground, and a raw material roller is rotatably installed on the left side of the support. A plastic packaging film is wound onto the raw material roller. A forming groove located on the right side of the raw material roller is fixedly installed on the top of the support, and an electric conveying roller for pulling the plastic packaging film is installed at the bottom of the forming groove. A frame placement area is provided between the raw material roller and the forming groove, and a placement component installed on the top of the support is provided in the frame placement area. The inner frame is intermittently placed onto the plastic packaging film by the placement component. A horizontally arranged heat-sealing component a is fixedly installed on the top left side of the forming channel, and a groove that runs through the left and right sides is opened at the bottom of the heat-sealing component a. The front and rear edges of the plastic packaging film are movably inserted into the groove. A heat-pressing module for sealing the front and rear edges of the plastic packaging film is fixedly installed on the inner end wall of the groove. A vertically arranged heat-sealing component b and a cutting component are installed sequentially from left to right on the forming channel. After the plastic packaging film is processed by the forming channel, heat-sealing component a, heat-sealing component b and cutting component, it forms a tea packaging bag with one end open and the other end closed. The inner frame is placed inside the tea packaging bag.

[0006] This method involves placing an inner frame inside the tea packaging bag during the processing. After packaging, the inner frame provides strong support within the tea packaging bag, preventing the packaging from breaking or the tea from being damaged due to compression. This effectively improves the pressure resistance of the packaged tea.

[0007] Optionally, the inner frame consists of twelve interconnected support rods, which are respectively set at the twelve edge lines of the inner frame. The outer dimensions of the inner frame are adapted to the inner dimensions of the tea packaging bag.

[0008] Furthermore, the support rod includes a sleeve disposed on the outer side and an insertion tube disposed on the inner side, the insertion tube and the sleeve are movably connected and communicate with each other, and the insertion tube and the sleeve are filled with safety gas.

[0009] Furthermore, multiple reinforcing ribs with triangular cross-sections are fixed around the inner wall of the cannula, and multiple reinforcing ribs are also fixed around the outer wall of the sleeve.

[0010] Furthermore, connecting blocks that are fixedly connected to the support rods are installed at the corners of the inner frame, and air passages that are connected to the inner sleeves and tubes of the support rods are opened inside the connecting blocks. One of the connecting blocks is provided with an air inlet that is connected to the air passage, and a one-way valve is installed in the air inlet.

[0011] Furthermore, the outer end wall of the connecting block away from the support rod is designed with an arc-shaped structure.

[0012] Optionally, the placement component includes a connecting base fixedly connected to the bracket, and a shaping chamber is rotatably mounted on the connecting base. The internal dimensions of the shaping chamber are adapted to the internal dimensions of the tea packaging bag. A servo motor for controlling the rotation and adjustment of the shaping chamber is installed on the connecting base. A lower opening is provided on the top of the shaping chamber, and an electric flip door is rotatably mounted on the right side of the shaping chamber.

[0013] Furthermore, a docking seat adapted to the connecting block is installed at the bottom corner of the shaping chamber, and an air inlet corresponding to the air inlet is provided on the docking seat. A positioning iron block is fixedly installed inside the connecting block on the outside of the air inlet, and an electromagnet for magnetic attraction of the positioning iron block is fixedly installed inside the docking seat.

[0014] Furthermore, the docking seat is located at the left corner of the bottom front of the shaping chamber, and the front of the shaping chamber is tilted downwards.

[0015] Furthermore, the heat-sealing component b includes two symmetrically arranged electric lifting platforms a, which move synchronously relative to each other. A heat-pressing module is fixedly installed on the end wall of the two electric lifting platforms a that are close to each other. The cutting component includes two symmetrically arranged electric lifting platforms b, which move synchronously relative to each other. A cutting blade is fixedly installed on the end wall of the two electric lifting platforms b that are close to each other. The bottom of the forming channel is provided with a slot through which the electric lifting platforms a and b pass.

[0016] Compared to existing technologies, the advantages of this application are:

[0017] (1) In the processing of tea packaging bags, the inner frame is placed inside the tea packaging bag so that after the packaging is completed, the inner frame can form a firm support inside the tea packaging bag, avoiding the situation that the packaging will break and the tea will be damaged due to squeezing after the tea is packaged, and effectively improving the pressure resistance of the tea after packaging.

[0018] (2) The inner frame is formed by twelve support rods to support the inside of the tea packaging bag. While ensuring the stability of the inner support, it can also effectively reduce the amount of material used in the inner frame, thereby reducing the packaging cost to a certain extent.

[0019] (3) A support rod is formed by using a sleeve and a tube to connect in an active manner, and a safety gas is filled in the sleeve and tube. With the support of the gas, the sleeve and tube can slide elastically, so that the inner frame formed can form an elastic support structure in the tea packaging bag, further improving the pressure resistance and impact resistance of the tea after packaging.

[0020] (4) By installing reinforcing ribs with triangular cross-sections around the outer end wall of the sleeve and the inner end wall of the insertion tube, the bending resistance of the sleeve and insertion tube can be effectively improved, which is conducive to improving the structural stability of the inner frame.

[0021] (5) The internal sleeves and inserts of multiple connecting rods are interconnected through the air passages in the connecting block, so that only one air injection port is needed to realize the injection of safety gas. At the same time, by installing a one-way valve in the air injection port, leakage during the injection of safety gas can be avoided, which is conducive to ensuring the ease of operation when the inner frame is gas-injected and formed.

[0022] (6) By setting the outer end wall of the connecting block to an arc shape, the surface of the connecting block can be avoided from being too sharp and puncturing the tea packaging bag, which is conducive to ensuring the protective stability and safety of the tea packaging after it is formed.

[0023] (7) By completing the inflation operation of the inner frame in the shaping chamber, the final support size of the inner frame can be flexibly adapted and adjusted according to the internal size of the actual tea packaging bag, which is conducive to improving the versatility of the inner frame and thus reducing the manufacturing cost of the inner frame.

[0024] (8) By setting the docking seat at the left corner of the front of the bottom of the shaping chamber and tilting the front of the shaping chamber downward, the inner frame automatically slides down to the left front position inside the shaping chamber by gravity, which is conducive to the automatic and accurate docking of the air inlet and the air outlet, further improving its automated operation and improving work efficiency.

[0025] (9) By setting both electric lifting platform a and electric lifting platform b to move symmetrically up and down, the two upper and lower heat pressing modules and the two upper and lower cutting blades can act on the plastic packaging film at the same time, which is conducive to improving the stability of heat pressing and cutting, and avoiding problems such as incomplete heat pressing and sealing and incomplete cutting.

[0038] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application. Example

[0039] This invention provides a pressure-resistant packaging device for tea. Please refer to [link / reference]. Figure 1 - Figure 10 The system includes a packaging prefabrication machine 1 and a tea filling machine. The packaging prefabrication machine 1 includes a support 101 fixedly installed on the ground, with a raw material roller 102 rotatably mounted on the left side of the support 101. A plastic packaging film 103 is wound onto the raw material roller 102. A forming groove 104 located to the right of the raw material roller 102 is fixedly installed on the top of the support 101, and an electric conveying roller for pulling the plastic packaging film 103 is installed at the bottom of the forming groove 104. A frame placement area 105 is provided between the raw material roller 102 and the forming groove 104, and a placement component 2 installed on the top of the support 101 is provided on the frame placement area 105. The placement component 2 intermittently places the plastic packaging film 103 onto the frame. The inner frame 3 has a horizontally arranged heat-sealing component a4 fixedly installed on the top left side of the forming channel 104, and the bottom of the heat-sealing component a4 has a groove that runs through the left and right sides. The front and rear edges of the plastic packaging film 103 are movably inserted into the groove. A heat-pressing module for sealing the front and rear edges of the plastic packaging film 103 is fixedly installed on the inner end wall of the groove. The forming channel 104 has a vertically arranged heat-sealing component b5 and a cutting component 6 installed from left to right. After the plastic packaging film 103 is processed by the forming channel 104, the heat-sealing component a4, the heat-sealing component b5 and the cutting component 6, it forms a tea packaging bag 7 with one end open and the other end closed. The inner frame 3 is placed inside the tea packaging bag 7.

[0040] During the use of this device, workers process the plastic packaging film 103 into tea packaging bags 7 that meet the requirements using the packaging prefabrication machine 1, ensuring that the inner frame 3 is supported inside the tea packaging bag 7. Subsequently, workers transport the processed tea packaging bags 7 to the tea filling machine, where compliant tea is filled into the tea packaging bags 7. Then, the opening of the tea packaging bags 7 is sealed by the sealing device inside the tea filling machine. In the processing of the tea packaging bags 7, this application places the inner frame 3 inside the tea packaging bags 7, so that after the subsequent packaging is completed, the inner frame 3 can form a firm support inside the tea packaging bags 7, avoiding the situation where the packaging is crushed and the tea is damaged after packaging, effectively improving the pressure resistance of the tea after packaging. Example

[0041] This invention provides a pressure-resistant packaging device for tea. Please refer to [link / reference]. Figure 1 - Figure 10 The inner frame 3 is composed of twelve interconnected support rods 301. The twelve support rods 301 are respectively set at the twelve edge lines of the inner frame 3. The outer dimensions of the inner frame 3 are adapted to the inner dimensions of the tea packaging bag 7. During the use of this device, the twelve support rods 301 form a hollow inner frame 3 to support the inside of the tea packaging bag 7. While ensuring the stability of the internal support, it can also effectively reduce the amount of material used in the inner frame 3, thereby reducing the packaging cost to a certain extent.

[0042] Please see Figure 7 - Figure 10 The support rod 301 includes a sleeve 302 on the outer side and an insertion tube 303 on the inner side. The insertion tube 303 and the sleeve 302 are movably connected and interconnected. The insertion tube 303 and the sleeve 302 are filled with safety gas. During use, the support rod 301 is formed by the movable connection of the sleeve 302 and the insertion tube 303. The sleeve 302 and the insertion tube 303 are filled with safety gas. With the support of the gas, the sleeve 302 and the insertion tube 303 can slide elastically, thereby forming an elastic support structure within the tea packaging bag 7. This is beneficial for the elastic buffering and weakening of the impact force when the tea packaging bag 7 is impacted after the tea packaging is formed, thus further improving the pressure resistance and impact resistance of the tea packaging.

[0043] Please see Figure 10Multiple reinforcing ribs 304 with triangular cross-sections are fixedly arranged around the inner end wall of the insertion tube 303, and multiple reinforcing ribs 304 are also fixedly arranged around the outer end wall of the sleeve 302. During the use of this device, by installing the reinforcing ribs 304 with triangular cross-sections around the outer end wall of the sleeve 302 and the inner end wall of the insertion tube 303, the bending resistance of the sleeve 302 and the insertion tube 303 can be effectively improved, which is conducive to improving the structural firmness of the inner frame 3. Furthermore, by placing the reinforcing ribs 304 outside the sleeve 302 and inside the insertion tube 303, the connection sealing between the sleeve 302 and the insertion tube 303 can be avoided, thus ensuring the stability of the inner frame 3 which is elastically supported by safe gas.

[0044] Please see Figure 8 and Figure 9 The inner frame 3 has connecting blocks 305 fixedly connected to the support rods 301 at its corners. The connecting blocks 305 have air passages that communicate with the inner sleeves 302 and inserts 303 of the support rods 301. One of the connecting blocks 305 has an air inlet 306 that communicates with the air passages. A one-way valve is installed in the air inlet 306. During use, by setting the connecting blocks 305 at each corner of the inner frame 3 and fixing them to the support rods 301, the air passages in the connecting blocks 305 connect the inner sleeves 302 and inserts 303 of multiple connecting rods to each other. This allows the injection of safety gas to be achieved by setting only one air inlet 306. At the same time, by installing a one-way valve in the air inlet 306, leakage during the injection of safety gas can be avoided, which helps to ensure the ease of operation when the inner frame 3 is being gas-molded.

[0045] Please see Figure 8 The outer end wall of the connecting block 305 away from the support rod 301 is set as an arc-shaped structure. During the use of this device, by setting the outer end wall of the connecting block 305 as an arc-shaped structure, it can prevent the surface of the connecting block 305 from being too sharp and puncturing the tea packaging bag 7, which is conducive to ensuring the protective stability and safety of the tea packaging after it is formed.

[0046] This embodiment 2 references embodiment 1, and the differences are formed based on embodiment 1. Only the differences are explained here. Example

[0047] This invention provides a pressure-resistant packaging device for tea. Please refer to [link / reference]. Figure 1 - Figure 10The placement component 2 includes a connecting base 201 fixedly connected to the bracket 101, and a shaping chamber 202 is rotatably mounted on the connecting base 201. The internal dimensions of the shaping chamber 202 are adapted to the internal dimensions of the tea packaging bag 7. A servo motor for controlling the rotation and adjustment of the shaping chamber 202 is installed on the connecting base 201. A lower opening 203 is opened on the top of the shaping chamber 202, and an electric flip door 204 is rotatably mounted on the right side of the shaping chamber 202.

[0048] During the use of this device, the operator places the uninflated inner frame 3 into the shaping chamber 202 through the lowering port 203. The inflation operation of the inner frame 3 is completed within the shaping chamber 202. After the inflation operation is completed in the shaping chamber 202, the outer dimensions of the inner frame 3 are extended to match the internal dimensions of the tea packaging bag 7. Then, the electric flip door 204 is opened, and the servo motor controls the shaping chamber 202 to deflect downwards to the right, tilting the inflated and extended inner frame 3 onto the plastic packaging film 103 in the frame placement area 105. The inner frame 3 moves synchronously with the plastic packaging film 103, ultimately forming a tea packaging bag 7 with the inner frame 3 inside. By completing the inflation operation of the inner frame 3 within the shaping chamber 202, the final support dimensions of the inner frame 3 can be flexibly adapted and adjusted according to the actual internal dimensions of the tea packaging bag 7, which is beneficial to improving the versatility of the inner frame 3 and thus reducing the manufacturing cost of the inner frame 3.

[0049] Please see Figure 6 The bottom corner of the shaping chamber 202 is equipped with a docking seat 205 that matches the connecting block 305. The docking seat 205 is equipped with an inflation nozzle 206 that corresponds to the air injection port 306. A positioning iron block is fixedly installed inside the connecting block 305 on the outside of the air injection port 306. An electromagnet for magnetic attraction of the positioning iron block is fixedly installed inside the docking seat 205. During the use of this device, the electromagnet on the docking seat 205 is energized and activated. Under the magnetic attraction of the electromagnet to the positioning iron block, the air injection port 306 and the inflation nozzle 206 are precisely docked. The inflation nozzle 206 is connected to an air pump to inflate the inner frame 3. After inflation, during the release of the inner frame 3, the electromagnet needs to be de-energized to make it lose its magnetic attraction to the positioning iron block, ensuring that the inner frame 3 is smoothly lowered after inflation.

[0050] Please see Figure 3The docking seat 205 is located at the left corner of the bottom front of the shaping chamber 202. The front of the shaping chamber 202 is tilted downwards. During the use of this device, when the uninflated inner frame 3 enters the shaping chamber 202, the servo motor is powered on and starts, controlling the left end of the shaping chamber 202 to tilt downwards. By setting the docking seat 205 at the left corner of the bottom front of the shaping chamber 202 and tilting the front of the shaping chamber 202 downwards, the inner frame 3 automatically slides down to the left front position inside the shaping chamber 202 by gravity. This facilitates the automatic and precise docking of the inflation nozzle 206 and the air injection port 306, further improving its automated operation and increasing work efficiency.

[0051] Please see Figure 4 The heat-sealing assembly b5 includes two symmetrically arranged electric lifting platforms a501, which move synchronously relative to each other. A heat-pressing module is fixedly installed on the end wall of the two electric lifting platforms a501 that are close to each other. The cutting assembly 6 includes two symmetrically arranged electric lifting platforms b601, which move synchronously relative to each other. A cutting blade is fixedly installed on the end wall of the two electric lifting platforms b601 that are close to each other. The bottom of the forming groove 104 is provided with a slot 106 through which the electric lifting platforms a501 and b601 pass. During the use of this device, by setting both electric lifting platforms a501 and b601 to move symmetrically up and down, the two heat-pressing modules and the two cutting blades can act on the plastic packaging film 103 at the same time. This helps to improve the stability of heat pressing and cutting, and avoids problems such as incomplete heat pressing and sealing, and incomplete cutting.

[0052] This embodiment 3 references embodiment 2, and the differences are formed based on embodiment 2. Only the differences are explained here.

[0053] The above are merely the best implementation methods adopted in this application in light of current practical needs, but the scope of protection of this application is not limited thereto.
