Description

Technical Field

[0001] The utility model relates to the technical field of food forming and processing, in particular to a demoulding and positioning device. Background Art

[0002] In order to meet the preferences of different people for food shapes, food molds are becoming more and more diversified. The food mold demoulding production line improves the degree of automation in the food production process and is widely used in the production of hawthorn, biscuits and other foods.

[0003] The applicant in this case disclosed a molded food automated production line in the Chinese newly applied utility model patent applied for and authorized on April 1, 2024, with the authorization announcement number CN221996708U. In order to improve the efficiency of food demolding, the applicant in this case improved the molded food automated production line in the patent and designed a food mold synchronous demolding production line. The basic principle is to design a mold connection station for transition between the mold stay station and the demolding station. When the flipping mechanism transfers the mold from the mold stay station to the mold connection station, it can directly return to the next step without waiting. The mold on the mold connection station is transferred to the demolding station by the upper mold conveying device for demolding, so that the demolding station and the mold stay station can operate synchronously, thereby improving the efficiency of food demolding.

[0004] In the existing technology, the demoulding station uses a flipping mechanism instead of a positioning mechanism during the demoulding process. However, since a newly designed food mold synchronous demoulding production line does not have the participation of a flipping mechanism, a demoulding positioning device needs to be redesigned to ensure the stability of the demoulding process.

[0005] The design requirements of the demoulding positioning device are: 1. It can conveniently and effectively restrict the mold to the demoulding position and prevent it from shaking left and right; 2. It has a simple structure and is easy to manufacture. Utility Model Content

[0006] The purpose of the utility model is to provide a demoulding positioning device with a simple structure, which can conveniently and effectively limit the mold to the demoulding station and prevent it from shaking, in order to solve the above problems.

[0007] The utility model is realized by using the following technical scheme: a demoulding positioning device comprises a frame, a mounting frame is fixedly mounted on the frame, a first mounting plate is mounted on the mounting frame and is driven up and down by a first driving mechanism, a conveying frame is mounted on the first mounting plate and can be driven left and right by a second driving mechanism, the conveying frame can abut against the right side of the mold, and a positioning block is also mounted on the frame and can be driven to rotate by a third driving mechanism, the positioning block can abut against the left side of the mold.

[0008] Through the above structure, the mold is fixed on the demoulding station under the joint action of the positioning block and the conveying frame, thereby preventing the demoulding device from deviating from the mold in the left and right directions during demoulding, making the demoulding process more stable.

[0009] Furthermore, the first drive mechanism includes a first cylinder fixedly mounted on the mounting frame, the output end of the first cylinder fixedly connected to a spherical plain bearing, a hinge seat fixedly mounted on the bottom of the first mounting plate, and the top end of the spherical plain bearing hingedly connected to the hinge seat. The provision of the first cylinder further facilitates the upward and downward movement of the first mounting plate.

[0010] Furthermore, a second mounting plate is slidably mounted on the front side of the first mounting plate, and the second mounting plate is fixedly connected to the conveyor frame. The arrangement of the second mounting plate facilitates the installation of the mobile frame and the sliding cooperation with the first mounting plate.

[0011] Furthermore, the second drive mechanism includes a motor fixedly mounted on the front side of the second mounting plate. The output end of the motor passes through the second mounting plate and is fixedly connected to a gear. A transversely disposed rack is fixedly mounted on the first mounting plate, and the rack and the gear mesh. The motor drives the gear and the rack to engage, allowing the second mounting plate to drive the motor and the movable frame to move left and right.

[0012] Furthermore, the third drive mechanism includes a second cylinder fixedly mounted on the frame. The output end of the second cylinder is fixedly connected to the first connecting rod. The right end of the first connecting rod is hingedly connected to the second connecting rod. The bottom of the second connecting rod is fixedly connected to a rotating shaft. The rotating shaft is fixedly connected to the positioning block. The two ends of the rotating shaft are rotatably engaged with the frame. The second cylinder drives the first and second connecting rods to drive the rotation of the positioning block, which allows for more diverse installation positions of the second cylinder and avoids conflicts with other mechanisms.

[0013] Furthermore, the rotating shaft is provided with three positioning blocks, which correspond to the front and rear ends and the middle of the left side of the mold respectively. The arrangement of the three positioning blocks further improves the stability of the mold.

[0014] Furthermore, the transport frame is composed of a straight rod and three parallel rods, forming an "E" shape. The straight rod is fixedly connected to the second mounting plate, and the bottoms of the three parallel rods are fixedly mounted with several transport blocks, which can abut against the right side of the mold. The arrangement of the transport blocks allows the transport frame to serve as both a mold moving device and a positioning device for the right side of the mold.

[0015] Furthermore, a vertically arranged first guide rail is fixedly mounted on the mounting frame, and a first slider is fixedly mounted on the first mounting plate, with the first guide rail and the first slider slidably engaged. The engagement of the first guide rail and the first slider allows the first mounting plate to move up and down only along the direction of the first guide rail, thereby improving the stability of movement between the first mounting plate and the mounting frame.

[0016] Furthermore, transversely disposed second guide rails are fixedly mounted on both the upper and lower sides of the first mounting plate, and a second slider is fixedly mounted on the rear side of the second mounting plate. The second guide rails and the second slider are slidably engaged with each other. The engagement between the second guide rails and the second slider allows the second mounting plate to move left and right only along the direction of the second guide rails, thereby making the movement between the second mounting plate and the first mounting plate more stable.

[0017] Furthermore, a support frame is fixedly installed on the frame, and the support frame is used to support the mold. Through the setting of the support frame, the mold can be prevented from being deformed under the extrusion of the demoulding device during demoulding, further increasing the stability of demoulding.

[0018] In summary, the beneficial effects of the present invention are:

[0019] The conveyor frame and positioning block work together to achieve positioning of the mold on the demolding station. In the positioning device, the conveyor frame can serve as both a conveying device for the mold and a positioning device on the right side of the mold, while the positioning block acts as a positioning mechanism on the left side of the mold. The two work together to ensure the stability of the mold when it enters the demolding station for demolding. By adding the positioning block to cooperate with the mold conveying mechanism, the structure of this device is simplified and easy to manufacture. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0029] The following is a description of preferred embodiments of the present invention with reference to the accompanying drawings.

[0030] like Figure 1 As shown, the utility model provides a demoulding positioning device, including a frame 1, on which a material tray conveying device 11 for conveying material trays is provided, a mounting frame 12 is fixedly installed on the frame 1, and a demoulding device 3 and a mold conveying mechanism 2 are installed on the mounting frame 12. The position of the demoulding device 3 corresponding to the frame 1 is a demoulding station, and a positioning mechanism 4 for positioning the mold 5 on the demoulding station is installed on the left side of the demoulding station; wherein, the material tray conveying device 11 and the demoulding device 3 are both prior arts, and the structure can refer to the newly applied Chinese utility model patent with application announcement number CN221996708U, a molded food automated production line, and no further details will be given here.

[0031] like Figure 1 、 Figure 2 、 Figure 5As shown, the mold conveying mechanism 2 includes a first mounting plate 23 slidably mounted on the mounting frame 12; specifically, a first slider 18 is fixedly mounted on the left and right ends and the middle of the rear side of the first mounting plate 23, and a vertically arranged first guide rail 13 is fixedly mounted at the position of the mounting frame 12 corresponding to the first slider 18, and the first guide rail 13 slides with the first slider 18. The first mounting plate 23 can move up and down along the direction of the first guide rail 13 under the drive of the first driving mechanism. A conveying frame 21 that can be driven by the second driving mechanism to move left and right is installed on the first mounting plate 23, and the conveying frame 21 can be abutted against the right side of the mold 5. The positioning mechanism 4 includes a positioning block 44 rotatably mounted on the frame 1, and the positioning block 44 can be rotated under the drive of the third driving mechanism and abutted against the left side of the mold 5 on the demolding station.

[0032] like Figures 2 to 4 As shown, the first driving mechanism includes a first cylinder 15 fixedly mounted on the mounting frame 12, the output end of the first cylinder 15 is fixedly connected to a joint bearing 16, the bottom of the first mounting plate 23 is fixedly mounted with a hinge seat 17, and the top end of the joint bearing 16 is hinged to the hinge seat 17.

[0033] A second mounting plate 24 is slidably mounted on the front side of the first mounting plate 23. Specifically, transversely disposed second guide rails 25 are fixedly mounted at both upper and lower ends of the front side of the first mounting plate 23. A second slider 28 is provided at a corresponding position on the rear side of the second mounting plate 24. The second guide rails 25 and the second slider 28 are slidably engaged. The second mounting plate 24 is fixedly connected to the conveyor frame 21.

[0034] To further illustrate this embodiment, the conveyor frame 21 is composed of a straight rod and three parallel rods. The conveyor frame 21 is "E"-shaped, with the straight rod fixedly connected to the second mounting plate 24. A plurality of conveyor blocks 22 are fixedly mounted at the bottom of each of the three parallel rods. The conveyor blocks 22 can abut against the right side of the mold 5. The three parallel rods enable the conveyor frame 21 to move three molds 5 simultaneously, making the demolding process of this device more efficient and the structure more stable.

[0035] The second driving mechanism mentioned above includes a motor 27 fixedly mounted on the front side of the second mounting plate 24, the output end of the motor 27 is fixedly connected to a gear 29 through the second mounting plate 24, and a horizontally arranged rack 26 is fixedly mounted on the first mounting plate 23, and the rack 26 is meshed with the gear 29.

[0036] The motor 27 can rotate forward and reverse, and the forward and reverse rotation of the motor 27 drives the second mounting plate 24 to drive the conveying frame 21 to move left and right, thereby driving the mold 5 to move left.

[0037] like Figure 2 、 Figure 5 、 Figure 6As shown, the third driving mechanism includes a second cylinder 41 fixedly mounted on the frame 1, the output end of the second cylinder 41 is fixedly connected to the first connecting rod 42, the right end of the first connecting rod 42 is hinged to the second connecting rod 43, the bottom of the second connecting rod 43 is fixedly connected to the rotating shaft 45, the rotating shaft 45 is fixedly connected to the positioning block 44, and both ends of the rotating shaft 45 are rotatably matched with the frame 1.

[0038] As a further illustration of this example, in order to further improve the stability of the mold 5 at the mold demolding station, three positioning blocks 44 are provided on the rotating shaft 45, and the three positioning blocks 44 correspond to the front and rear ends and the middle of the left side of the mold 5 respectively.

[0039] As a further illustration of this example, since the mold 5 is in an undemolded state when it is transferred from the mold staying station to the mold connecting station, its own weight is relatively heavy, and the mold 5 is generally made of plastic, the frame 1 only supports the front and rear ends of the mold 5. At this time, under the action of gravity, the middle part of the mold 5 is prone to deform downward, so a support frame 14 is fixedly installed on the frame 1 at the position where the undemolded mold 5 passes, that is, a support frame 14 is fixedly installed on the frame 1 corresponding to the mold connecting station and the demolding station. The support frame 14 is used to support the mold 5 to prevent the mold 5 from deformation, thereby further ensuring the stability of the demolding process.

[0040] The operating principle of this device is as follows: when the support frame 14 moves the mold 5 to be demolded to the demolding station, the support frame 14 stops moving. At this time, the conveying block 22 at the bottom of the rightmost parallel rod on the support frame 14 is against the right side of the mold 5 at the demolding station. At this time, the second cylinder 41 is started, and the output end of the second cylinder 41 extends, and the second cylinder 41 drives the positioning block 44 to rotate, so that the positioning block 44 is against the left side of the mold 5 at the mold stop station. The positioning of the mold 5 is achieved through the cooperation of the positioning block 44 and the conveying block 22. When the demolding is completed, the second cylinder 41 is retracted, and the positioning block 44 rotates in the opposite direction, so as not to affect the conveying frame 21 to drive the mold 5 to continue to move to the left.

[0041] In summary, the demoulding positioning device provided by the present invention realizes the positioning of the mold 5 on the demoulding station through the cooperation of the conveying frame 21 and the positioning block 44. In the positioning device, the conveying frame 21 can serve as both a conveying device for the mold 5 and a positioning device on the right side of the mold 5, while the positioning block 44 serves as a positioning mechanism on the left side of the mold 5. The two cooperate with each other to ensure the stability of the mold 5 when the mold 5 enters the demoulding station for demoulding. By adding the positioning block 44 to cooperate with the mold conveying mechanism 2, the structure of the device is simpler and easier to manufacture.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
