Description
Technical Field
[0001] This utility model belongs to the field of pressing equipment technology, specifically an agricultural product pressing machine. Background Technology
[0002] In existing processes, to ensure that certain agricultural products and fruits have uniform dimensions when sold, they are usually pressed using molding molds. Traditional molding molds consist of an upper mold and a lower mold. During operation, the product to be processed is first placed in the cavity of the lower mold, and then the upper mold is closed to press it.
[0003] However, existing molds are inconvenient to handle and transfer due to their large size, and their installation and positioning on the press are also cumbersome, affecting work efficiency. Furthermore, products often cannot be instantly shaped after pressing, requiring the upper and lower molds to remain locked in the pressing position for a certain period to achieve shape stability. While commonly used pressing equipment can complete the pressing action, the mold locking can only be completed after it leaves the press, which can easily lead to product deformation and rebound within the mold, making it difficult to meet the process requirements of continuous pressure holding. Therefore, a dedicated pressing device is proposed that facilitates the transport, positioning, and pressing of molds on the press, and allows for easy control of the mold locking and holding function, thereby improving production automation and processing quality. Utility Model Content
[0004] To address the above problems, this utility model provides an agricultural product pressing machine, which solves the problems of transporting and positioning the mold on the pressing machine, as well as controlling the locking of the mold during the pressing process.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An agricultural product pressing machine includes a pressing block that can move up and down, with the top of the pressing block connected to a first drive source; a conveyor chain assembly that can be lifted up and down is provided below the pressing block for conveying a mold; a base is provided below the conveyor chain assembly; a blocking cylinder that restricts the movement of the mold along the conveying direction is provided on the base; and a side plate is provided on one side of the base for abutting against the side of the mold.
[0007] On the other side of the base, there is a first push plate for locking the locking push rod on the mold. A second push plate is elastically and movably arranged on the lower side of the first push plate. The second push plate can contact the side of the mold and push the mold to cooperate with the side plate to push the mold against the side, so that its side is positioned parallel to the conveying direction.
[0008] As a further improvement to the above solution, a support seat is provided on the top surface of the base, and several recessed receiving grooves are provided on the support seat, and the conveyor chain assembly is arranged in the receiving grooves.
[0009] The conveyor chain components in the receiving slots at different positions are transmitted synchronously, and a second drive source is provided on the base to drive the conveyor chain components to move up and down in the receiving slots.
[0010] As a further improvement to the above solution, a support plate is provided on the top of the support base, and the support plate has a concave top pressure groove. The side of the mold can be reliably connected to the top pressure groove and abut against each other with the side plate.
[0011] As a further improvement to the above solution, a concave thrust groove is provided on the top of the support base near the first push plate, and the second push plate is movably disposed in the thrust groove.
[0012] The top of the second push plate has a push head that extends toward the receiving groove side to facilitate contact and push with the mold.
[0013] As a further improvement to the above solution, the first push plate has a sliding groove, and a sliding column is slidably arranged in the sliding groove. One end of the sliding column is fixed to the second push plate. An elastic member sleeved on the outside of the sliding column is provided between the side of the second push plate and the side of the first push plate, so as to automatically reset the second push plate when the first push plate is pushed out.
[0014] As a further improvement to the above solution, a third driving source is connected to the first push plate to drive its movement, and a photoelectric limit switch for detecting the push position of the first push plate is fixedly installed on the top of the base. The photoelectric limit switch is connected to the third driving source through a controller signal.
[0015] As a further improvement to the above solution, a number of support columns are fixedly installed on the top of the base, and a top seat that is fixed to the first drive source is fixedly installed on the top of the support columns.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. The set conveyor chain assembly enables automatic transportation of the mold. The mold on the conveyor chain assembly can be blocked by the blocking cylinder to limit the transportation position of the mold and achieve the first positioning. Under the combined action of the push of the second push plate and the push of the side plate, the arrangement of the mold can be adjusted to achieve the second positioning, thereby maintaining the optimal pressing position of the mold. During the pressing process, the upper and lower molds can be locked synchronously by the push of the locking push rod by the first push plate, thereby achieving automatic locking control.
[0018] 2. The position of the first push plate is determined by the photoelectric limit switch. When the first photoelectric limit switch detects the position, the first push plate drives the second push plate to push the mold, achieving the positioning effect. When the second photoelectric limit switch detects the position, the first push plate will directly push the locking push rod to lock the mold. At this time, under the action of the sliding column, the second push plate will not move synchronously with the first push plate, but will be restricted and stop moving due to the obstruction of the thrust groove. When the first push plate retracts and resets, the elastic element pushes the second push plate to stay in the position on the thrust groove. The sliding column and the sliding groove are not completely sliding. After the elastic element is fully extended, the sliding column can pull back a small range on the thrust groove to reserve space for mold placement. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0030] like Figure 1-6 As shown, the specific solution of this embodiment is as follows: an agricultural product pressing machine includes a pressing block 1 that can move up and down, the top of the pressing block 1 is connected to a first driving source, specifically, the first driving source is a hydraulic cylinder; a conveyor chain assembly 2 that can be lifted up and down is provided below the pressing block 1, such as... Figure 1 , 2 As shown in Figure 4, the conveyor chain assembly 2 consists of three conveyor chains connected by a support side plate. A drive motor for driving the chain movement is connected to the support side plate. The drive motor is connected to a reduction motor to drive the chain movement. The mold 20 is placed on the upper side of the chain. When the chain moves, it is used to convey the mold 20. A base 3 is provided below the conveyor chain assembly 2. Several support columns 9 are fixedly provided on the top of the base 3. A top seat 10 that is fixed to the first drive source is fixedly provided on the top of the support columns 9.
[0031] A blocking cylinder 5 is provided on the base 3 to restrict the movement of the mold 20 along the conveying direction. The blocking cylinder 5 mainly serves to block and limit the mold 20 when it is conveyed on the chain. A side plate 4 is provided on one side of the base 3 for abutting against the side of the mold 20. A first push plate 6 is provided on the other side of the base 3 for locking the locking push rod 201 on the mold 20. The first push plate 6 is connected to a drive cylinder. A second push plate 61 is elastically and movably provided on the lower side of the first push plate 6. The second push plate 61 can contact the side of the mold 20 and push the mold 20 to cooperate with the side plate 4 to abut against the mold 20, so that its side is positioned parallel to the conveying direction. After the second push plate 61 abuts against the mold 20, it can push the mold 20 to adjust its placement position, thereby achieving a second positioning under the pushing of the side plate 4 and the second push plate 61.
[0032] like Figure 5 As shown, in a preferred embodiment, a support base 7 is provided on the top surface of the base 3, and a plurality of recessed receiving grooves 71 are provided on the support base 7. The conveyor chain assembly 2 is arranged in the receiving grooves 71. The conveyor chain assembly 2 in the receiving grooves 71 at different positions is transmitted synchronously, and a second drive source is provided on the base 3 to drive the conveyor chain assembly 2 to move up and down in the receiving grooves 71. Specifically, the second drive source is also a hydraulic cylinder, which is mainly used to transport the mold 20 to contact the blocking cylinder 5 by the chain on the conveyor chain assembly 2. After reaching the first limit, the hydraulic cylinder drives the conveyor chain assembly 2 to descend and be retracted into the receiving groove 71, and the mold 20 is placed on the top surface of the support base 7.
[0033] The top of the support base 7 is provided with a support plate 41, and the support plate 41 has a concave top pressure groove 42. The side of the mold 20 can be reliably connected to the top pressure groove 42 and abut against each other with the side plate 4. Therefore, in this embodiment, after the top pressure groove 42 on the support plate 41 abuts against the side of the mold 20, it plays the role of adjusting the arrangement position of the mold 20.
[0034] like Figure 3 , 5 As shown in Figures 6 and 7, in a preferred embodiment, the top of the support base 7 is provided with a recessed thrust groove 72 on the side near the first push plate 6, and the second push plate 61 is movably disposed within the thrust groove 72. Figure 6 As shown; the top of the second push plate 61 has a push head 611 extending toward the receiving groove 71. The push head 611 is convenient to contact the mold 20 and push it to move. The push head 611 and the second push plate 61 are integrally constructed. When the push head 611 moves toward the mold 20, it directly contacts the bottom side of the mold 20, thereby achieving the function of pushing the mold 20, so as to adjust the arrangement position of the mold 20.
[0035] As a preferred embodiment of the above, the first push plate 6 has a groove 64, and a sliding post 62 is slidably disposed in the groove 64. The sliding post 62 can slide in the groove 64, but cannot slide out directly. A limiting plate is provided at the end of the sliding post 62 to restrict the sliding post 62 from sliding out. One end of the sliding post 62 is fixed to the second push plate 61. An elastic member 63 sleeved on the outside of the sliding post 62 is provided between the side of the second push plate 61 and the side of the first push plate 6. In this embodiment, the elastic member 63 is a spring. The spring can facilitate the automatic reset of the second push plate 61 when the first push plate 6 is pushed out. Under the restriction of the limiting plate, the sliding post 62 can be prevented from sliding out of the groove 64. When the first push plate 6 retracts, the second push plate 61 can be pulled back part after the elastic member 63 is fully extended, thereby reserving space at the top of the support base 7 for placing the mold 20.
[0036] like Figure 1 , 2 As shown in Figure 3, in a preferred embodiment, a third driving source is connected to the first push plate 6 to drive its movement. The third driving source is also a hydraulic cylinder. A photoelectric limit switch 8 for detecting the pushed-out position of the first push plate 6 is fixedly installed on the top of the base 3. Figure 3In this embodiment, two photoelectric limit switches 8 are provided to detect the two working positions of the first push plate 6. The photoelectric limit switches 8 are connected to the third drive source through the controller signal. The specific controller is the control system that controls the movement of the entire press, such as a PLC controller. Therefore, after the two photoelectric limit switches 8 feed back the detected position signals to the controller, the controller can drive the first push plate 6 to push out different distances. When the first push plate 6 moves to the position detected by the first photoelectric limit switch 8, it pushes the second push plate 61 to move the mold 20 to achieve the second positioning of the mold 20. When the first push plate 6 moves to the position detected by the second photoelectric limit switch 8, the second push plate 61 no longer moves forward, and the first push plate 6 pushes the locking push rod 201 to lock the mold 20.
[0037] like Figure 7 , 8 As shown in Figure 9, a first latch 202 is connected to the locking push rod 201 of the lower mold, and the first latch 202 and the locking push rod 201 are slidably disposed relative to each other. A second latch 203 is connected to the locking push rod 201 of the upper mold, as shown in Figure 9. Figure 8 After the upper and lower molds are closed, the first latch 202 and the second latch 203 will insert into each other. When the locking push rod 201 is pushed, the locking push rod 201 of the upper mold will simultaneously drive the second latch 203 to engage with the first latch 202, thereby completing the locking of the upper and lower molds.
