Description

Technical Field

[0001] This utility model relates to the field of packaging and filling technology, specifically to a pre-prepared vegetable packaging and filling production line. Background Technology

[0002] Pre-prepared meals, with their significant advantages of eliminating the need for ingredient procurement and simplifying preparation steps, have become an important choice for convenient dining. After hygienic processing and scientific packaging, these dishes only require simple cooking methods such as heating, steaming, or stir-frying to be served directly, greatly satisfying the dietary needs of people living fast-paced lives. In the production process of pre-prepared meals, the packaging and filling stage plays a crucial role; its standardized operation directly affects product quality and production efficiency.

[0003] A search revealed that patent CN221969947U discloses a pre-packaged food filling production line. Although the device uses a moving screw plate to discharge the pre-packaged food boxes during use, facilitating their removal, the current filling equipment has several shortcomings. Firstly, the device does not take effective measures to close or protect the opening of the boxes during filling, leading to easy material splashing. This not only wastes raw materials but may also contaminate the production environment and affect product hygiene. Secondly, the boxes remain inside the frame after filling, making it inconvenient for personnel to handle. This reduces production continuity, increases the complexity of manual operation, and hinders production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pre-packaged food filling production line, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A pre-packaged food filling production line includes a frame, a pre-packaged food filling machine, and a cover plate.

[0007] A pre-made vegetable filling machine is installed on the rear end face of the frame, a bearing panel is installed on the inner wall of the frame, and a first hydraulic rod is installed on the top face of the frame.

[0008] The bearing panel has a placement groove, and a mounting bracket is welded to the bottom surface of the bearing panel. A third hydraulic rod is mounted on the bottom surface of the mounting bracket, and an ejector block is mounted on the output shaft of the third hydraulic rod via a fixing plate.

[0009] A filling tube is fixedly installed on the output shaft of the first hydraulic rod, and a fixing bracket is installed on the filling tube. A cover plate is installed on the bottom end face of the fixing bracket through a return spring.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, a second hydraulic rod is installed inside the bearing panel, and a clamping block is fixedly installed on the output shaft of the second hydraulic rod, the clamping block being slidably sleeved in the placement groove.

[0012] The beneficial effects of adopting the above-mentioned further solutions are:

[0013] Once the packaging box is placed in the placement slot, the second hydraulic rod drives the clamping block to slide within the slot, thereby clamping and securing the packaging box. This effectively prevents the packaging box from shifting or tipping over due to external forces during the filling process, ensuring that the filling tube is aligned with the opening of the packaging box, improving filling accuracy, and reducing material spillage caused by packaging box shaking, thus enhancing production stability.

[0014] Furthermore, the ejector block is slidably fitted into the placement groove, and the inner diameter of the placement groove is adapted to the size of the ejector block.

[0015] The beneficial effects of adopting the above-mentioned further solutions are:

[0016] The adaptive design of the ejector block and the placement slot allows the ejector block to slide smoothly up and down within the placement slot under the drive of the third hydraulic rod. When not in use, the ejector block also supports the packaging boxes placed in the placement slot. After filling, the ejector block can push the packaging boxes out of the placement slot for quick removal by operators, eliminating the need for manual prying and reducing the tediousness of manual operation, thus improving production efficiency. At the same time, the adaptive dimensions prevent the ejector block from jamming or shifting during movement, ensuring smooth ejection.

[0017] Furthermore, a limiting rod is welded to the bottom end face of the fixing plate, and the limiting rod is slidably sleeved within the mounting frame.

[0018] The beneficial effects of adopting the above-mentioned further solutions are:

[0019] As the fixed plate moves with the output shaft of the third hydraulic rod, the limiting rod slides synchronously within the mounting bracket, strictly limiting and guiding the movement direction of the fixed plate. This prevents the fixed plate from tilting or wobbling when moving the ejector block, ensuring that the ejector block always moves along the axis of the placement slot, guaranteeing precise alignment between the ejector block and the placement slot, improving the stability and reliability of the ejection operation, and preventing damage to the packaging box or affecting the ejection effect due to ejector block misalignment.

[0020] Furthermore, a connecting pipe is installed on the rear end face of the filling pipe, and the end of the connecting pipe opposite to the filling pipe is installed inside the pre-cooked vegetable filling machine.

[0021] The beneficial effects of adopting the above-mentioned further solutions are:

[0022] The connecting pipe establishes a material conveying channel between the pre-cooked vegetable filling machine and the filling pipe, allowing the material in the pre-cooked vegetable filling machine to flow smoothly into the filling pipe through the connecting pipe, and then be injected into the packaging box through the filling pipe.

[0023] Furthermore, a guide rod is fixedly installed on the top surface of the cover plate, and the guide rod is slidably sleeved within the fixing frame.

[0024] The beneficial effects of adopting the above-mentioned further solutions are:

[0025] As the cover moves up and down with the extension and retraction of the return spring, the guide rod slides within the fixed frame, guiding the movement of the cover. This prevents the cover from shifting or rotating during movement, ensuring it remains horizontal and closes securely at the opening of the packaging box. During filling, the cover effectively prevents material splashing, and the guide rod enhances the stability of the connection between the cover and the fixed frame, preventing the cover from shaking due to material impact and ensuring reliable splash prevention.

[0026] This utility model provides a pre-packaged food filling production line. It has the following beneficial effects:

[0027] The design of the cover plate and return spring enables the packaging box opening to be closed during the filling process, preventing material from splashing due to pressure. This reduces raw material waste, avoids contamination of the packaging exterior, reduces the workload of subsequent cleaning processes, and improves the cleanliness of the production environment.

[0028] The clamping block driven by the second hydraulic rod firmly secures the packaging box, preventing displacement or tipping during filling and ensuring the filling tube is aligned with the opening, thus improving filling accuracy. Combined with the matching design of the ejector block and placement slot, this further ensures the stability of the packaging box throughout the entire process of placement, filling, and removal, reducing material spillage caused by shaking and improving the operational stability of the production line.

[0029] The ejector block driven by the third hydraulic rod can eject the packaging box from the placement slot after filling, replacing the manual prying operation, simplifying the material handling process, and avoiding the inconvenience of taking out the packaging box after filling.

Detailed Implementation

[0039] 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.

[0040] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0041] Example 1

[0042] A pre-packaged food filling production line includes a frame 1, a pre-packaged food filling machine 3, and a cover plate 6.

[0043] A pre-made vegetable filling machine 3 is installed on the rear end face of frame 1, a load-bearing panel 2 is installed on the inner wall of frame 1, and a first hydraulic rod 4 is installed on the top face of frame 1.

[0044] The bearing panel 2 has a placement groove 201. The bottom end face of the bearing panel 2 is welded with a mounting bracket 7. The bottom end face of the mounting bracket 7 is equipped with a third hydraulic rod 701. The output shaft of the third hydraulic rod 701 is equipped with an ejector block 704 through a fixing plate 703.

[0045] A filling tube 5 is fixedly mounted on the output shaft of the first hydraulic rod 4. A fixing bracket 501 is mounted on the filling tube 5. A cover plate 6 is mounted on the bottom end of the fixing bracket 501 via a return spring 602. The fixing bracket 501 provides a stable mounting base for the cover plate 6, enabling the cover plate 6 to form a linkage structure with the filling tube 5. When the filling tube 5 moves downward with the first hydraulic rod 4 and approaches the packaging box, the cover plate 6 will first contact the opening of the packaging box. As the filling tube 5 continues to move downward, the return spring 602 will be compressed. At this time, the cover plate 6 can fit tightly against the opening of the packaging box, effectively preventing material splashing caused by filling pressure during the filling process, reducing material waste and contamination of the packaging exterior. When filling is completed and the filling tube 5 moves upward, the return spring 602 will return to its original state, driving the cover plate 6 to return synchronously, without obstructing the removal of the packaging box.

[0046] A second hydraulic rod 202 is installed inside the support panel 2. A clamping block 203 is fixedly installed on the output shaft of the second hydraulic rod 202. The clamping block 203 is slidably sleeved in the placement groove 201. When the packaging box is placed in the placement groove 201, the second hydraulic rod 202 can drive the clamping block 203 to slide in the placement groove 201, thereby clamping and fixing the packaging box. This can effectively prevent the packaging box from shifting or tipping over due to external forces during the filling process, ensuring that the filling tube 5 can be aligned with the opening of the packaging box, improving the accuracy of filling, and reducing material spillage caused by the shaking of the packaging box, thus improving the stability of production.

[0047] The ejector block 704 is slidably fitted into the placement groove 201. The inner diameter of the placement groove 201 is adapted to the size of the ejector block 704. This adaptive design allows the ejector block 704 to slide smoothly up and down within the placement groove 201 under the drive of the third hydraulic rod 701. When not in use, the ejector block 704 can support the packaging boxes placed in the placement groove 201. After filling, the ejector block 704 can eject the packaging boxes from the placement groove 201, allowing operators to quickly remove them without manually prying them out, reducing the tediousness of manual operation and improving production efficiency. Simultaneously, the adapted dimensions prevent the ejector block 704 from jamming or shifting during movement, ensuring smooth ejection.

[0048] A limiting rod 702 is welded to the bottom end face of the fixed plate 703. The limiting rod 702 is slidably sleeved within the mounting frame 7. When the fixed plate 703 moves with the output shaft of the third hydraulic rod 701, the limiting rod 702 slides synchronously within the mounting frame 7, strictly limiting and guiding the movement direction of the fixed plate 703. This prevents the fixed plate 703 from tilting or shaking when moving the ejector block 704, ensuring that the ejector block 704 always moves along the axis of the placement groove 201, guaranteeing the precise fit between the ejector block 704 and the placement groove 201, improving the stability and reliability of the ejection operation, and avoiding damage to the packaging box or affecting the ejection effect due to the displacement of the ejector block 704.

[0049] Example 2

[0050] To close the opening of the packaging box during the filling of pre-prepared food and prevent material from splashing during filling, for example, such as Figures 1 to 5 As shown, this utility model also includes:

[0051] A connecting pipe 301 is installed on the rear end face of the filling pipe 5. The end of the connecting pipe 301 facing away from the filling pipe 5 is installed inside the pre-cooked vegetable filling machine 3. The connecting pipe 301 establishes a material conveying channel between the pre-cooked vegetable filling machine 3 and the filling pipe 5, so that the material in the pre-cooked vegetable filling machine 3 can flow smoothly into the filling pipe 5 through the connecting pipe 301, and then be injected into the packaging box by the filling pipe 5.

[0052] A guide rod 601 is fixedly installed on the top surface of the cover plate 6. The guide rod 601 is slidably sleeved within the fixing frame 501. When the cover plate 6 moves up and down with the extension and retraction of the return spring 602, the guide rod 601 slides within the fixing frame 501, providing guidance for the movement of the cover plate 6. This prevents the cover plate 6 from shifting or rotating during movement, ensuring that the cover plate 6 always remains horizontal, thus closing at the opening of the packaging box. During filling, the cover plate 6 effectively blocks material splashing. At the same time, the setting of the guide rod 601 also enhances the stability of the connection between the cover plate 6 and the fixing frame 501, preventing the cover plate 6 from shaking due to material impact and ensuring the reliability of the anti-splash effect.

[0053] Furthermore, the first hydraulic rod 4, the second hydraulic rod 202, and the third hydraulic rod 701 of the production line can all be controlled by external control switches. The power supply control principle and circuit connection method of the external control switches are common functional module designs, which are common knowledge in the fields of electrical automation control and mechanical equipment. The relevant technologies are widely used and the principles are clear, so there is no need to elaborate further.

[0054] Working principle:

[0055] Material loading positioning:

[0056] The operator places the empty pre-prepared food packaging box into the placement slot 201 of the support panel 2.

[0057] The second hydraulic rod 202 is activated, driving the clamping block 203 to slide within the placement slot 201, clamping and fixing the packaging box from both sides to ensure its stable position.

[0058] Filling preparation:

[0059] The first hydraulic rod 4 is activated, and its output shaft drives the filling tube 5 to move downwards, approaching the opening of the packaging box in the placement slot 201.

[0060] The fixing bracket 501 moves down synchronously with the filling tube 5, and the cover plate 6 connected by the return spring 602 first contacts the opening of the packaging box.

[0061] Anti-splash filling:

[0062] The filling tube 5 continues to move downward under the action of the first hydraulic rod 4. At this time, the cover plate 6 stops due to contact with the packaging box, the return spring 602 is compressed, and the cover plate 6 fits against the opening of the packaging box to form a seal.

[0063] When the pre-made food filling machine 3 starts, the material flows into the filling pipe 5 through the connecting pipe 301 and is then injected into the packaging box. Due to the obstruction of the cover plate 6, the material will not splash outside the packaging due to the filling pressure.

[0064] Reset after filling:

[0065] After filling is completed, the first hydraulic rod 4 drives the filling tube 5 to move upward.

[0066] The reset spring 602 returns to its original state, causing the cover plate 6 to move upward synchronously, detaching from the opening of the packaging box, without hindering subsequent material handling operations.

[0067] Finished product output:

[0068] The third hydraulic rod 701 is activated, and its output shaft pushes the ejector block 704 to slide upward in the placement groove 201 through the fixing plate 703.

[0069] The ejector block 704 ejects the filled packaging box from the placement slot 201, allowing operators to easily remove the finished product.

[0070] The limit rod 702 slides within the mounting bracket 7 during the movement of the fixed plate 703, ensuring that the ejector block 704 moves smoothly along the axis of the placement groove 201, avoiding deviation or jamming.

[0071] Cyclic operation:

[0072] After the finished product is removed, the third hydraulic rod 701 drives the ejector block 704 to return to the bottom of the placement slot 201.

[0073] The production line returns to its initial state, waiting for the next empty packaging box to be inserted, and repeats the above steps to achieve continuous production.

[0074] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0075] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
