Description

Technical Field

[0001] The present invention relates to the technical field of feed preparation equipment, in particular to a continuous tablet pressing device for preparing pet feed. Background Art

[0002] The tableting process in pet food preparation involves carefully processing various raw materials, such as meat, grains, vitamins, and minerals, and then using a tablet press to compress them into pellets or chunks of a specific shape and hardness. This process not only helps extend the shelf life of the feed, facilitates packaging and transportation, but also precisely meets the nutritional needs of pets, making it an indispensable part of the pet food production process.

[0003] Typically, during the preparation process, various raw materials are first crushed and thoroughly mixed, and then appropriate amounts of water, oil, and other additives are added to form a wet material. These wet materials are then added layer by layer into a mold to achieve a stacking effect of two or more raw materials, and then a tablet press is used to form the final product. Although the above method is effective, it still has certain limitations in practical application: 1. Currently, in the preparation process of multi-color and multi-ingredient feed, the feeding process mostly relies on manual or semi-automatic equipment for intermittent operation, resulting in a less smooth process. 2. When producing feed containing two or more ingredients, the need to precisely control the proportion and order of addition of each ingredient increases operational difficulty, requiring more equipment support or human resources, thus affecting production continuity and efficiency; 3. During the feeding process, the feed is easily retained when entering the template hole from the feeding frame, causing the feed to pile up and difficult to fall off. This not only affects the stacking of two or more ingredients of feed, resulting in the upper layer of feed being unable to smoothly enter the hole to form, but also may make the stratification effect unclear when pressing multi-color feed. Summary of the Invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a continuous tabletting device for preparing pet feed that is highly automated and easy to produce multi-color feed, thereby optimizing the production process, improving processing efficiency, and ensuring product quality.

Therefore, they cannot be understood as limiting the present invention.

[0025] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0026] Example: A continuous tabletting device for preparing pet food, such as Figures 1-6 Shown, including: The base 1 is hollow inside, with a partition 11 provided between the left and right inner walls at the rear of the base 1, and a pressing assembly for tablet pressing provided on the top of the base 1; The mounting frame 3 is fixedly arranged between the left and right inner walls of the machine base 1, the highest points of the mounting frame 3 and the partition 11 are on the same horizontal line, and the mounting frame 3 is connected to the front end of the partition 11, and a template 31 with extrusion holes 311 arranged therein is detachably provided on the top of the mounting frame 3. The template 31 is one of the main molds for forming feed tablets. The detachable design of the template 31 facilitates subsequent cleaning work. An ejection mold 32 is sliding in the mounting frame 3, which allows the ejection hole 311 to pass through. The ejection mold 32 slides in the up and down directions, and the upper part of the ejection mold 32 has a protrusion that is consistent with the layout and shape arrangement order of the extrusion holes 311, so that the ejection mold 32 can slide smoothly and be embedded in the corresponding extrusion hole 311 through the protrusion, thereby assisting in pressing or ejecting the feed tablets; a cylinder 2 33 with a telescopic end connected to the bottom surface of the ejection mold 32 is fixedly provided at the bottom of the machine base 1, which is used to push the ejection mold 32 to move and realize automatic operation; Specifically, the ejection mold 32 is driven to rise and fall by the cylinder 2 33 to achieve precise ejection of the ejection mold 32. By adjusting the driving stroke of the cylinder 33, the moving distance of the ejection mold 32 is accurately adjusted to reach different height positions. The space in which the protruding part of the ejection mold 32 is embedded in the extrusion hole 311 is also changed accordingly, so that the space in which the extrusion hole 311 can be used to place the feed raw materials can be accurately controlled, so that the placement amount of various feed raw materials can be accurately controlled. By analogy, various raw materials can be accurately stacked, and the preparation of multi-color and multi-component feed can be realized. Then, in conjunction with the pressing component, the stacked raw materials can be pressed, and finally a finished product of multi-color feed is obtained.

[0027] Additional frames 4 are provided on the left and right sides of the machine base 1, and the two additional frames 4 are located on the left and right sides of the mounting frame 3 respectively. A discharge port for raw materials is provided on the top of the additional frames 4 and the rear side of the top of the machine base 1. The discharge port is connected to a material pipe that is higher than the top surface of the corresponding additional frame 4 or the machine base 1. The material pipe serves as the main channel for conveying raw materials, and can guide the raw materials to fall smoothly from a high place and flow into the interior of the device, thereby ensuring that the entire discharge process is efficient and smooth. There are three push frames 5, which are respectively slid in the two additional frames 4 and on the partition 11. The raw materials flowing in through the material pipes at various places will enter the push frames 5 at the corresponding positions, and the required raw materials are loaded by using the push frames 5. A sieve plate 52 is provided in the push frame 5 to assist in feeding. The sieve plate 52 has holes that are adapted to the layout of the extrusion holes 311, and an electric push rod 51 is fixedly installed on the top rear side of the machine base 1 and the top of the additional frame 4. The telescopic ends of the electric push rod 51 are respectively connected to the adjacent push frames 5 to automatically push the push frame 5 to move after feeding, so as to align the holes of the sieve plate 52 with the extrusion holes 311, so as to realize accurate unloading of raw materials, ensure orderly addition of raw materials, and make the operation simpler and more coherent. Moreover, the push frame 5 at the rear position also has a pushing function, which can be used to push the compressed feed tablets to complete the discharge. The material dispersing component 6 is used to clear the feed. The material dispersing component 6 includes a support plate 61. Each push frame 5 is provided with a group of support plates 61. There are two support plates 61 in each group. A rotating frame 62 is rotated between the two support plates 61 in the same group. Both ends of the rotating frame 62 are provided with a hollow rod body extending downward. A sleeve rod 63 is slidably embedded in the hollow rod body at both ends of the rotating frame 62. A roller frame 64 that can be inserted into the extrusion holes 311 at various places and is used for dispersing feed is rotated between the ends of the sleeve rod 63 on the same side. The rollers arranged on the roller frame 64 are adapted to the layout of the extrusion holes 311 on the corresponding moving track, and a spring 65 is provided between the sleeve rod 63 and the corresponding rotating frame 62.

[0028] Specifically, under the elastic support of the spring 65, the sleeve rod 63 and the roller frame 64 are continuously subjected to a downward force, ensuring that the roller frame 64 can always maintain a close fit with the template 31 when following the movement of the push frame 5, and because of the roller layout of the roller frame 64, the roller will automatically embed into the extrusion hole 311 during the movement, providing downward pushing power for the retained raw materials. The raw materials are compressed and fall to the bottom layer of the extrusion hole 311, so that the raw materials can be concentrated in the same area to ensure the concentration of the raw materials input this time, and at the same time effectively ensure the smooth flow of the extrusion hole 311 channel, solving the problem of uneven material discharge. In addition, when multiple layers of raw materials are stacked, the stratification between the layers of the prepared multi-color feed can be made more obvious and beautiful, thereby significantly improving the overall production quality.

[0029] like Figure 1 、 Figure 3 and Figure 4 As shown, the pressing assembly includes a bracket 2 arranged between the left and right sides of the top of the base 1, and a cylinder 21 with a telescopic end facing downward is fixedly installed on the top of the bracket 2. The telescopic end of the cylinder 21 is connected to a pressing mold 22 adapted to the template 31 for extrusion molding of the feed; and a detachable shell connected by bolts is provided on the telescopic end of the cylinder 21, and the pressing mold 22 is assembled in the shell, forming a detachable connection structure between the cylinder 21 and the pressing mold 22, so as to facilitate subsequent cleaning processing, thereby ensuring the cleanliness of the preparation environment each time and avoiding the accumulation of residual materials.

[0030] like Figure 6 As shown, a conductive frame 53 is provided between the inner walls of each push frame 5, and the conductive frame 53 is connected to the inner walls on all sides. A vibration rod 531 is provided in the middle of the conductive frame 53, and the number of vibration heads of the vibration rod 531 is two, and the vibration head of the vibration rod 531 is in contact with the adjacent screen plate 52 for shaking and assisting the discharge of the raw materials.

[0031] Specifically, with the center of the sieve plate 52 as the base point of action, the vibration rod 531 vibrates to cooperate with the conduction frame 53 to realize synchronous vibration conduction of the push frame 5 and the sieve plate 52, so that the vibration frequency of the raw materials placed on the sieve plate 52 is more uniform, to ensure that the raw materials can be evenly shaken and effectively discharged, thereby realizing an automated and uniform raw material screening process.

[0032] like Figure 1 、 Figure 3 and Figure 4 As shown, a conveying assembly 7 is provided between the front inner walls of the machine base 1. The conveying assembly 7 is a conveying member composed of a conveyor roller and a conveyor belt. This is a prior art and will not be elaborated on. Leakage holes 71 are arranged on the conveyor belt of the conveying assembly 7. A collecting frame 72 is slidingly provided on the right side of the machine base 1. The collecting frame 72 is embedded under the conveyor belt of the conveying assembly 7 to collect raw material residues mixed in the finished feed product.

[0033] like Figure 2-Figure 4 As shown, the pushing frame 5 is provided with a pushing plate 8 for scraping off the residual raw material, and the length of the pushing plate 8 is adapted to the width of each side of the mounting frame 3, and the end of the pushing plate 8 is in contact with the inner wall of the corresponding additional frame 4 or the inner wall of the machine base 1, ensuring that the scraping of the raw material can be more comprehensive and thorough.

[0034] Working principle: First, before starting the device, the staff needs to prepare all kinds of required preparation raw materials, and pour all kinds of raw materials into the corresponding pushing frames 5 through the material pipes on the machine base 1 and the additional frame 4, so that the raw materials are placed on the corresponding sieve plates 52 respectively, and then start the cylinder 2 33 to drive the ejection mold 32 to move upward a certain distance, and the convex part of the ejection mold 32 is embedded in the corresponding extrusion hole 311 on the template 31, and then part of the space of the extrusion hole 311 is filled by the ejection mold 32, and the reserved position is used as the space for adding raw materials, and then start the electric push rod 51 on one side to drive the corresponding pushing frame 5 together with its upper parts to move toward the template 31, and the pushing frame 5 gradually approaches the template 31 until the hole position of the sieve plate 52 in the pushing frame 5 is aligned with the extrusion hole 311, and start the vibration rod 531 to shake the raw materials on the sieve plate 52, so that the raw materials fall through the hole position into the extrusion hole 311 just below, and the space inside the extrusion hole 311 is completely filled to complete the feeding operation of this raw material; Next, the corresponding electric push rod 51 drives the pushing frame 5 to reset after the material is added, and then the second cylinder 33 is activated to drive the ejection mold 32 to move down a certain distance to reserve space for the next raw material to be added. Then the raw materials accumulated on the upper layer fall down and accumulate in the lower space. However, some raw materials may not fall completely and remain on the upper layer of the extrusion hole 311, resulting in the raw materials not being gathered in the same area. Then another electric push rod 51 can be activated to drive the pushing frame 5 loaded with another raw material to move toward the template 31; When the pushing frame 5 moves, the rotating frame 62 and its upper components move synchronously with it. Under the elastic action of the spring 65, the sleeve rod 63 and the roller frame 64 always maintain a downward force. The spring 65 deforms adaptively, and the sleeve rod 63 slides accordingly, prompting the roller frame 64 to move in accordance with the template 31. Then, the rollers on the roller frame 64 are embedded in each extrusion hole 31 on the path as they move. The rotating frame 62 rotates and tilts in accordance with the movement, and the rollers on the roller frame 64 press the retained raw materials, thereby ensuring the aggregation of the raw materials and ensuring that the upper space of each extrusion hole 311 is always reserved. Then, the raw materials inside the moving pushing frame 5 can smoothly fall into the reserved space of the extrusion hole 311 to be stacked to the upper position of the previous raw materials, completing the stacking process of the raw materials. By analogy, the above operation is repeated to drive the push frame 5 loaded with different raw materials to feed the materials so that the raw materials are stacked. During this process, the push plate 8 moves with the push frame 5 to synchronously scrape off the excess residual materials on the template 31 to ensure a clean secondary feeding environment. After all kinds of raw materials have been added, cylinder 1 21 and cylinder 2 33 are started synchronously. During the upward movement of the ejection mold 32, the pressing mold 22 is moved downward synchronously. After the two are fitted together, the raw materials in the extrusion hole 311 are extruded and formed until the feed tablets are formed. Cylinder 1 21 drives the pressing mold 22 to move upward, and cylinder 2 33 drives the ejection mold 32 to continue to move upward, so that each feed tablet is extruded through the extrusion hole 311, and then the electric push rod 51 on the rear side is started to drive the connected pushing frame 5 to move, and the pushing plate 8 connected to it moves synchronously, thereby pushing the feed tablets on the template 31 and pushing the feed tablets onto the conveying component 7. Then the residual material mixed in the feed leaks into the central frame 72 through the leakage hole 71, and the pressed feed is discharged along with the conveying component 7, thus completing the overall tableting process.

[0035] It can be seen that the structural design of this device is simple and reasonable, and the operating process is clear and continuous. Especially in the preparation process of multi-ingredient feed, its high efficiency and precision characteristics can significantly improve the efficiency of the production line while ensuring the stability and improvement of product quality.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
