Description

Technical Field

[0001] The utility model relates to the technical field of plant planting, and more specifically, to a mold for producing a substrate cultivation trough. Background Art

[0002] As the country pays more and more attention to modern facility agriculture, cultivation troughs are widely used by farmers in greenhouses and sheds. At present, there are some common defects in the molds for producing cultivation troughs on the market: it is difficult to extrude and shape, and one person's independent operation may easily cause product deformation and damage; when producing cultivation troughs, the wall thickness increased due to production fluctuations may cause the material to be blocked at the entrance of the shaping mold and unable to enter the shaping mold, causing production interruption problems.

[0003] The existing CN205255382U discloses a shaping device for XPS special-shaped cross-section profiles, including a workbench and a main unit component, a profile extrusion die, a front shaping sleeve and a rear shaping sleeve arranged on the workbench in sequence. The main unit component is connected to the inlet of the profile extrusion die, the inlet of the front shaping sleeve is provided with a conical introduction angle, and the rear shaping sleeve is provided with a refrigeration circulation water circuit. The utility model adopts two-stage shaping, namely, pre-shaping and final shaping, so that the geometric dimensions of the products of the same batch are very consistent with the geometric dimensions of the contour of the shaping sleeve, which brings great convenience to the installation and construction of the end user. The front shaping sleeve is provided with a conical introduction angle, and the conical introduction angle increases the taper of the inlet of the front shaping sleeve. In the above scheme, the conical introduction angle of the front shaping sleeve reduces the sensitivity to the fluctuation of the main unit, and the allowable fluctuation range is larger, thereby greatly reducing the frequency of semi-finished products stuck in the feed port, effectively improving the production efficiency of the product. However, in the above scheme, during the pulling process of the cultivation trough product, especially when pulling the single-wall cultivation trough, one person operating independently is likely to cause deformation and damage to the product. It often requires the cooperation of three people to successfully pull the cultivation trough at the extrusion outlet into the shaping mold. The operation is complicated and requires a lot of manpower, which will increase the production cost to a certain extent. Utility Model Content

[0004] The utility model aims to overcome the deficiencies in the prior art and provide a mold for producing a substrate cultivation trough, so that a production operator can independently pull the product into the shaping mold and avoid deformation and damage of the product.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] Provided is a mold for producing a substrate cultivation trough, comprising an extrusion die, a plurality of segmentation knives and a shaping die, wherein the extrusion die is provided with an extrusion port, a plurality of segmentation knives are rotatably connected to the extrusion die and arranged beside the extrusion port, and the shaping die is arranged behind the extrusion die.

[0007] The utility model is used to produce a mold for substrate cultivation troughs. During the traction process, the cultivation trough is divided into several parts by a dividing knife after passing through the extrusion port die, and the production operator independently pulls different parts of the product into the finalizing die one after another; after the traction is completed, the dividing knife is moved or turned away from the position intersecting with the extrusion port, and the various parts of the structure in the molten state are merged into a whole. The utility model is used to produce a mold for substrate cultivation troughs. During the traction process, the cultivation trough is divided into multiple parts, and each part is pulled in batches one after another, so as to avoid the cultivation trough being bent in multiple places and unable to enter the finalizing die at the same time, resulting in jamming and tearing when entering the finalizing die, affecting the product quality; therefore, the production operator of the utility model independently pulls the product into the finalizing die, and can avoid deformation and damage of the product.

[0008] Furthermore, the shape and size of the extrusion port of the extrusion die and the inlet of the shaping die are the same, so that the cultivation trough formed by the extrusion port die, after entering the shaping die for cooling and shaping, the cross-sectional shape and size of the produced substrate cultivation trough are the same as those of the extrusion port.

[0009] Furthermore, the segmentation knife includes a connecting portion and a cutting portion which are connected, the connecting portion is provided with a first connecting hole, the extrusion die is provided with a second connecting hole, and a connecting piece is connected in the first connecting hole and the second connecting hole. The tightness of the connection between the connecting piece and the extrusion die is adjusted so that the segmentation knife rotates to a vertical position under the action of its own gravity; when it is necessary to cut the cultivation trough, the segmentation knife is rotated to a specified position, and the connecting piece is tightened, and the segmentation knife is fixed to the extrusion die through the connecting piece to prevent the segmentation knife from rotating during operation, resulting in failure to segment the cultivation trough in an expected manner, which may cause the segmented cultivation troughs to have irregular shapes and be difficult to be pulled into the shaping die.

[0010] Furthermore, there are two splitting knives, which are installed in the horizontal direction and respectively cross the two sides of the extrusion port. The two splitting knives can cut any position of the two side walls of the cultivation trough within the rotation range of the splitting knives. The two splitting knives are installed in the horizontal direction and can serve as references to each other, making it easier for the production operator to accurately adjust the position of the splitting knives and obtain the cultivation trough structure of each part with a suitable shape.

[0011] Furthermore, an introduction device is provided in front of the inlet of the shaping die, which is used to guide the substrate cultivation trough from the extrusion die into the shaping die.

[0012] Furthermore, the two ends of the introduction device are respectively provided with a first introduction port and a second introduction port, the first introduction port is arranged close to the extrusion port, the second introduction port is arranged close to the shaping die, and the second introduction port has the same shape and size as the shaping die, the shape of the first introduction port is the same as the shape of the second introduction port, and the area of ​​the first introduction port is larger than the area of ​​the second introduction port. The cultivation trough enters from the first introduction port and exits from the second introduction port, and is compressed between the first introduction port and the second introduction port, and the cultivation trough is introduced into the shaping die entrance after being compressed into a suitable thickness, so as to avoid the cultivation trough being blocked in front of the shaping die entrance due to thickness changes and unable to enter the shaping die, causing production interruption problems.

[0013] Furthermore, a tapered structure is formed between the first inlet and the second inlet, and the width of the cross section of the tapered structure gradually decreases from the first inlet to the second inlet, thereby simplifying the processing technology and reducing the production cost.

[0014] Furthermore, the extrusion port is a symmetrical polygonal structure with an opening at the top, which can extrude the material into a single-layer cultivation trough structure of a corresponding shape, so that the product can accommodate the matrix and avoid matrix loss.

[0015] Furthermore, the bottom edge of the symmetrical polygonal structure is horizontally arranged, and the side edge of the symmetrical polygonal structure is connected with a hook-shaped structure, and the hook-shaped structure is bent toward the outside of the substrate cultivation trough produced by the mold, so that the produced substrate cultivation trough can be hung and placed using the hook structure, thereby expanding the use scenarios of the substrate cultivation trough, improving space utilization, and facilitating the production operator to carry it.

[0016] Furthermore, the bottom edge of the symmetrical polygonal structure is connected with a plurality of reinforcing structures, so that the pressure that the produced substrate cultivation trough can withstand is increased and the structural strength of the cultivation trough is improved.

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

[0018] The mold for producing a substrate cultivation trough of the utility model can divide the product into a plurality of parts, so that a production operator can independently pull the product into the shaping mold without causing deformation or damage of the product, thereby reducing labor costs.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0026] Embodiment 1

[0027] like Figure 1 and Figure 2 The utility model is shown as an embodiment of a mold for producing a substrate cultivation trough, comprising an extrusion die 1, a plurality of segmentation knives 2 and a shaping die 4, wherein the extrusion die 1 is provided with an extrusion port 11, the plurality of segmentation knives 2 are connected to the extrusion die 1 and are arranged beside the extrusion port 11, and the shaping die 4 is arranged behind the extrusion die 1.

[0028] When this embodiment is implemented, the raw material is extruded into a cultivation trough structure in the extrusion die 1, extruded from the extrusion port 11, and cut into several parts by the dividing knife 2 arranged beside the extrusion port 11. The production operator independently pulls the different parts of the product into the shaping die one after another; after the pulling is completed, the dividing knife is moved or turned away from the position intersecting with the extrusion port, and the various parts of the structure in the molten state are merged into a whole. During the pulling process, by dividing the cultivation trough into multiple parts, each part is pulled in batches one after another, so as to avoid the cultivation trough being bent in multiple places and unable to enter the shaping die at the same time, resulting in jamming and tearing when entering the shaping die, affecting the product quality; therefore, the production operator of the utility model can independently pull the product into the shaping die without causing deformation or damage to the product, thereby reducing labor costs.

[0029] The shape and size of the extrusion port of the extrusion die and the inlet of the shaping die are the same, so that the cultivation trough formed by the extrusion port die, after entering the shaping die for cooling and shaping, the cross-sectional shape and size of the produced substrate cultivation trough are the same as those of the extrusion port.

[0030] In this embodiment, the segmentation knife 2 includes a connecting portion 21 and a cutting portion 22 which are connected and arranged, the connecting portion 21 is provided with a second connecting hole 23, the extrusion die 1 is provided with a first connecting hole 12 corresponding to the second connecting hole 23, and a connecting member 3 is inserted into the first connecting hole 12 and the second connecting hole 23. In this embodiment, the connecting member 3 and the first connecting hole 12 are connected by a threaded connection, and the segmentation knife can be switched between a fixed state and a rotatable state by changing the tightness of the threaded connection. The connecting member 3 is a locking screw, and the screw diameter of the connecting member 3 is equal to or slightly smaller than the diameter of the second connecting hole 23, so that the screw can pass through the first connecting hole 12, and the head diameter of the connecting member 3 is larger than the diameter of the second connecting hole 23, which can limit the position of the connecting portion 21 and prevent the connecting portion 21 from slipping off the connecting member 3. The first connecting hole 12 is provided with threads, and the screw of the connecting member 3 cooperates with the internal threads of the first connecting hole 12. The depth of the threaded part of the first connecting hole 12 is greater than the difference between the screw length of the connecting member 3 and the thickness of the connecting part 21 to ensure the strength of the threaded connection.

[0031] The connecting portion 21 is a column with a thickness greater than that of the cutting portion 22. The second connecting hole 23 can be provided on the segmentation knife without increasing the thickness of the cutting portion, and it is convenient for the production operator to hold the segmentation knife 2 for installation. The cutting portion 22 is connected to the side of the connecting portion 21. A blade is provided on one side of the cutting portion 22, and the blade faces the extrusion port 11 to achieve cutting of the cultivation trough. The tip of the cutting portion 22 is rounded, which can prevent the production operator from being cut during the adjustment and installation of the segmentation knife 2, thereby improving production safety.

[0032] The splitting knives 2 are provided with two, which are respectively arranged on both sides of the extrusion port 11 and respectively cross the two sides of the extrusion port 11. By rotating the two splitting knives 2, cutting can be performed at any position on the two side walls of the cultivation trough within the rotation range of the splitting knives 2. The two splitting knives 2 can divide the cultivation trough into three parts, which can achieve the purpose of avoiding deformation of the cultivation trough and completing the traction work by one person in batches. Setting more than three splitting knives 2 and dividing the cultivation trough into more parts will make the process too cumbersome, increase production time, and cause an increase in the error rate, thereby increasing the instability of production. The two splitting knives 2 are arranged in the horizontal direction and can serve as references to each other, so that the production operator can more easily and accurately adjust the position of the splitting knife 2, improve the cutting accuracy, and obtain the structure of each part of the cultivation trough that meets the expectations.

[0033] In actual production, the connector 3 is inserted into the first connecting hole 12 and the second connecting hole 23, so that the segmentation knife 2 rotates to a vertical position under the action of its own gravity. The segmentation knife 2 can be rotated with the connector 3 as the center of the circle to change the angle between the cutting portion 22 and the horizontal direction, thereby adjusting the position where the segmentation knife 2 cuts the cultivation trough, obtaining the required component structure, and improving the flexibility of production. After the position of the segmentation knife 2 is determined, the connector 3 is tightened to fix the segmentation knife 2 to prevent the segmentation knife 2 from rotating during the production process, resulting in the inability to segment the cultivation trough in the expected manner, which may cause the shapes of the various parts of the cultivation trough obtained by cutting to be irregular, making it difficult to pull all parts into the shaping mold 4, and interrupting the shaping work. After the cultivation trough is pulled into the shaping mold, the tightness of the connector 3 is adjusted, and the segmentation knife 2 is rotated to a position that does not intersect with the extrusion port, or the segmentation knife 2 is rotated to a vertical position under the action of its own gravity, so that the segmentation knife 2 cannot continue to cut the cultivation trough for subsequent production.

[0034] In addition, the connecting member 3 and the first connecting hole 12 can also be connected by means of snap connection, key connection, etc., which do not require a rotating connecting member. When the connecting member 3 and the first connecting hole 12 are connected by snap connection, key connection, etc., before pulling the cultivation trough, the connecting member 3 is used to fix the dividing knife 2 on the first connecting hole 12. After the traction stage is over, the connecting member 3 is taken out, the dividing knife 2 is removed, and subsequent production is carried out.

[0035] The extrusion port 11 is a symmetrical polygonal structure with an opening at the top, which can extrude the material into a single-layer cultivation trough structure of a corresponding shape, so that the product can accommodate the matrix and avoid the loss of the matrix.

[0036] Embodiment 2

[0037] like Figure 3 and Figure 4The second embodiment of the mold for producing a substrate cultivation trough of the utility model is shown. This embodiment is similar to the first embodiment, except that, in this embodiment, it also includes an introduction device 5, which is arranged in front of the entrance of the shaping mold 4 and is used to guide the substrate cultivation trough from the extrusion die 1 into the shaping mold 4.

[0038] The front and rear ends of the introduction device 5 are respectively provided with a first introduction port 51 and a second introduction port 52, the first introduction port 51 is arranged at a position close to the extrusion die 1, the second introduction port 52 is arranged at a position close to the shaping die 4, and the second introduction port 52 has the same shape and size as the shaping die 4, the shape of the first introduction port 51 is the same as the shape of the second introduction port 52, and the area of ​​the first introduction port 51 is larger than the area of ​​the second introduction port 52, when the thickness of the cultivation trough increases due to production fluctuations, the cultivation trough can be compressed into a suitable thickness through the first introduction port 51 and the second introduction port 52 and then introduced into the entrance of the shaping die 4, so as to avoid the cultivation trough being blocked in front of the entrance of the shaping die 4 due to thickness changes and unable to be pulled into the shaping die 4, causing production interruption problems.

[0039] A conical structure, a conical structure or an arc-shaped structure is formed between the first introduction port 51 and the second introduction port 52. In this embodiment, a conical structure 53 is used. The width of the cross section of the conical structure 53 gradually decreases from the first introduction port 51 to the second introduction port 52. The inner wall of the conical structure 53 is a plane connected to each other. The processing technology of the plane is relatively simple, which reduces the production difficulty and production cost.

[0040] Embodiment 3

[0041] like Figure 1 The third embodiment of the mold for producing a substrate cultivation trough of the utility model is shown. This embodiment is similar to the second embodiment, except that the extrusion port 11 is a symmetrical polygonal structure with a horizontal bottom edge, which can prevent the cultivation trough from deforming due to uneven force caused by gravity when it is extruded from the extrusion port 11. The symmetry line of the extrusion port 11 is the center line of the extrusion port die 1, which is conducive to the production operator to accurately adjust the cutting position of the segmentation knife 2, improve the cutting accuracy, and obtain the cultivation trough structure of each part that meets the expectations.

[0042] The side of the symmetrical polygonal structure is connected with a hook-shaped structure 13, and the hook-shaped structure 13 is bent toward the outside of the produced substrate cultivation trough, so that the produced substrate cultivation trough can be hung and placed using the hook-shaped structure 13, which expands the use scene of the substrate cultivation trough, and can be placed in a stacked manner with other cultivation troughs, thereby improving space utilization and planting efficiency. At the same time, the hook-shaped structure 13 of the substrate cultivation trough is conducive to the production operator's handling of the cultivation trough.

[0043] The bottom edge of the symmetrical polygonal structure is provided with a plurality of reinforcing structures 14, and the reinforcing structures 14 are connected to the bottom edge, so that the pressure that the produced substrate cultivation trough can withstand is increased, and the structural strength of the cultivation trough is improved. The reinforcing structures 14 are rectangular, triangular, circular, etc. structures. In this embodiment, the reinforcing structures 14 are rectangular structures. The reinforcing structures 14 are evenly and symmetrically distributed on the bottom edge of the polygonal structure of the extrusion port 11, and the distances between the reinforcing structures 14 are equal, so that the bottom force of the produced substrate cultivation trough is more uniform, and the strength of the substrate cultivation trough is improved.

[0044] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
