DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-5 The utility model provides a technical solution: a threaded extruder for puffed food production, comprising a frame 1, a threaded extruder body 3 is fixedly connected to the upper surface of the frame 1, a feed port 2 is connected to the upper surface of the threaded extruder body 3, a discharge tray 4 is fixedly connected to the output end of the threaded extruder body 3, a positioning device 5 is provided on the side of the threaded extruder body 3, and a limit device 6 is provided at one end of the threaded extruder body 3 close to the discharge tray 4.

[0032] The specific arrangement and function of the positioning device 5 and the limiting device 6 will be described in detail below.

[0033] like Figure 1-Figure 4As shown, the positioning device 5 includes a support plate 51, which is fixedly connected to one end of the threaded extruder body 3 near the discharge tray 4. Two slide bars 54 are slidably connected to the inner wall of the threaded extruder body 3, and the surfaces of the two slide bars 54 are sleeved with a clamping plate 52. The support plate 51 can play a role in positioning and lifting the discharge tray 4 during the installation of the discharge tray 4, and the clamping plate 52 can be installed on the threaded extruder body 3 through the slide bar 54, and the discharge tray 4 to be installed can be limited in position through the clamping plate 52. One end of the two slide bars 54 near the clamping plate 52 is fixedly connected to a limiting plate 55, and both sides of the threaded extruder body 3 are fixedly connected with an arc plate 53. The limiting plate 55 can ensure that the clamping plate 52 will not be separated from the slide bar 54, and the arc plate 53 can guide the movement of the clamping plate 52.

[0034] The inner wall of the arc plate 53 is provided with two slide grooves, and the surfaces of the slide grooves on the two arc plates 53 are slidably connected with slide bars 57, and the side of the slide bars 57 close to each other is fixedly connected to the card plate 52. The slide bars 57 slidably connected to the surface of the slide grooves on the arc plate 53 can move, thereby ensuring that the card plate 52 can move, and the connection between the card plate 52 and the arc plate 53 can be ensured by the slide bars 57. The end of the slide bar 57 close to the thread extruder body 3 is fixedly connected with a rectangular plate 58, and the surface of the slide bar 54 is covered with a first spring 56, and the two ends of the first spring 56 are respectively fixedly connected to the card plate 52 and the thread extruder body 3. The rectangular plate 58 can ensure the stable installation of the slide bar 57, and the first spring 56 can play an auxiliary effect on the movement of the card plate 52, and the first spring 56 can ensure the stable connection between the card plate 52 and the thread extruder body 3.

[0035] like Figure 1 and Figure 5 As shown, the limiting device 6 includes two second arc blocks 64, which are respectively fixedly connected to the side of the clamping plate 52 away from the discharge tray 4, and the first arc block 63 is installed on the side of the clamping plate 52 close to the second arc block 64. The first arc block 63 and the second arc block 64 can limit the position of the clamping plate 52 after the clamping plate 52 moves, so that the discharge tray 4 can be installed conveniently.

[0036] One end of the threaded extruder body 3 close to the first arc block 63 is fixedly connected to two fixed plates 61, and the inner walls of the two fixed plates 61 are slidably connected with connecting rods 62, and one end of the connecting rod 62 is fixedly connected to the first arc block 63. The connecting rod 62 can be installed on the threaded extruder body 3 through the fixed plate 61, and the connecting rod 62 slidably connected to the inner wall of the fixed plate 61 can be moved, and the position of the first arc block 63 can be moved through the connecting rod 62. The other end of the connecting rod 62 is fixedly connected to a connecting plate 65, and the surface of the connecting rod 62 is covered with a second spring 66, and the two ends of the second spring 66 are fixedly connected to the fixed plate 61 and the connecting plate 65 respectively. The position of the connecting rod 62 can be conveniently moved through the connecting plate 65, and the second spring 66 can ensure that the connecting rod 62 will not be separated from the fixed plate 61.

[0037] Working principle: When using the threaded extruder for puffed food production to produce and process puffed food, the raw materials are first passed into the threaded extruder body 3 through the feed inlet 2. After being processed by the threaded extruder body 3, the puffed food is output through the discharge tray 4. When it is necessary to replace the discharge tray 4, first move the clamping plate 52 away from the discharge tray 4, then remove the original discharge tray 4 from the screw extruder body 3, and then move the discharge tray 4 to be installed close to the supporting plate 51, and release the clamping plate 52. At this time, the clamping plate 52 drives the sliding bar 57 to slide on the surface of the sliding groove on the arc plate 53 under the action of the elastic force of the first spring 56, so that the clamping plate 52 moves close to the discharge tray 4, restricting the position of the discharge tray 4, and the sliding bar 54 can install the clamping plate 52 on the screw extruder body 3. The limiting plate 55 can ensure that the clamping plate 52 will not be separated from the sliding bar 54, and the rectangular plate 58 can ensure the stable installation of the sliding bar 57. By setting the positioning device 5, a positioning effect can be achieved when installing the discharge tray 4, which facilitates the installation of the discharge tray 4, thereby improving the positioning accuracy of installing the discharge tray 4 and increasing the efficiency of installing the discharge tray 4.

[0038] When installing the discharge tray 4, first move the clamping plate 52 to drive the second arc block 64 to move close to the first arc block 63. The arc surfaces of the second arc block 64 and the first arc block 63 contact each other, thereby pushing the second arc block 64 to drive the connecting rod 62 to slide on the inner wall of the fixed plate 61, so that the connecting plate 65 moves close to the frame 1. When the second arc block 64 moves away from the first arc block 63, under the action of the elastic force of the second spring 66, the connecting plate 65 moves close to the fixed plate 61. When the discharge tray 4 to be installed is close to the supporting plate 51, the connecting plate 65 is moved away from the fixed plate 61. At this time, the clamping plate 52 is in the Under the action of the elastic force of a spring 56, it moves close to the discharge tray 4 to temporarily limit the position of the discharge tray 4, and the connecting plate 65 is loosened. Under the action of the elastic force of the second spring 66, the first arc block 63 approaches the second arc block 64 to limit the position of the second arc block 64, thereby limiting the position of the clamping plate 52. By setting the limit device 6, the position of the clamping plate 52 can be limited when the discharge tray 4 is replaced, thereby facilitating the control of the position of the clamping plate 52 and avoiding the need for staff to limit the position of the clamping plate 52 all the time when installing the discharge tray 4, thereby facilitating the installation of the discharge tray 4.
