Description

Technical Field

[0001] This utility model belongs to the field of poultry processing technology, specifically relating to a poultry scalding device. Background Technology

[0002] In poultry slaughtering and processing, scalding devices use hot water to soften the skin of poultry to improve the efficiency of subsequent hair removal.

[0003] In the prior art, patent document CN110810486A discloses a scalding machine. The machine frame has a water tank, with rotating shafts rotatably connected to both ends of the water tank. A turntable, rotating synchronously with the turntable, is fixedly connected to each end of the rotating shaft. Two parallel sieve plates are positioned between the two turntables, with their left and right ends fixedly connected to the two turntables respectively. This scalding machine and other traditional scalding devices employ a fixed-plate structure. To meet the discharge requirements, the plate needs to maintain a large radial deflection angle to form a sufficient guiding slope. However, an excessively large radial deflection angle can create a narrow cavity between the plate and the bottom of the tank. When the plate pushes the poultry carcass at the bottom of the hot water layer, it may excessively compress the carcass, causing injury. Utility Model Content

[0004] This invention addresses the shortcomings of existing fixed-plate structures by providing a poultry scalding device.

[0005] To solve one, some, or all of the above-mentioned technical problems, the technical solution adopted by this utility model is:

[0006] A poultry scalding device includes a pot body with a horizontal central axis. Turntables are coaxially arranged at both ends of the pot body, and cam grooves are fixedly arranged on the axial end faces of the pot body. A lever is arranged between the two turntables. A swing shaft is fixedly arranged on one side of the lever near the peripheral edge of the turntable, and the swing shaft is rotatably connected to the two turntables. Fixed arms are arranged at both ends of the swing shaft. The first end of the fixed arm is fixedly connected to the swing shaft, and the second end is slidably connected to the cam groove directly or through a hinged connecting rod.

[0007] Furthermore, there are two levers, and the central axes of the two swing axes are coplanar with the central axis of the turntable.

[0008] Furthermore, the fixed arms are all disposed between the turntable and the axial end face of the adjacent pot body.

[0009] Furthermore, a roller is fixedly provided at the end of the fixed arm away from the swing axis, and the roller is disposed in the cam groove.

[0010] Furthermore, the fixed arm is provided with a hinged connecting rod at one end away from the swing axis, and a roller is fixedly provided on the connecting rod, the roller being disposed in the cam groove.

[0011] Furthermore, the outer sleeve of the roller is provided with a bearing or a sliding sleeve.

[0012] Furthermore, there are two connecting rods, which are hinged together, and the roller is mounted on the connecting rod away from the fixed arm; the end of the connecting rod away from the fixed arm is rotatably connected to the turntable.

[0013] Furthermore, the cam groove includes an arc segment and a variable diameter segment with a decreasing radius, wherein the radial direction of the minimum radius of the variable diameter segment faces downwards from the discharge port of the pot body.

[0014] Furthermore, a lid is provided on the top of the pot body.

[0015] Furthermore, each turntable is coaxially fixed with a drive shaft, which extends to the outside of the pot body and is connected to the same drive source.

[0016] Furthermore, the side of the turntable is frustum-shaped or cone-shaped.

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

[0018] The paddle of this invention is rotatably connected to two turntables on both sides via a swing shaft. Simultaneously, the swing shaft is fixedly connected to a fixed arm, the end of which is directly or slidably connected to a cam groove via a connecting rod. When the drive turntable rotates, it drives the paddle to move synchronously. Due to the constraint of the cam groove, the radial deflection angle of the paddle continuously changes. When the paddle moves towards the discharge port to prepare for discharge, the radial deflection angle of the paddle gradually increases, facilitating the sliding of poultry carcasses onto the paddle to the discharge port. When agitating poultry carcasses at the bottom of the water, the paddle maintains a small radial deflection angle, avoiding squeezing or jamming the carcasses, and effectively turning them over for thorough scalding.

[0031] To better understand this utility model, the content of this utility model is further explained clearly below with reference to the embodiments and accompanying drawings. However, the protection scope of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0032] Example 1: See Figures 1-5 The purpose of this embodiment is to provide a poultry scalding device, including a pot body 1, a turntable 3, a dial plate 5, and a cam groove 4.

[0033] The pot body 1 is cylindrical with a horizontal central axis, and is horizontally mounted on a support structure such as a bracket or frame. A hinged or detachable lid 2 is provided on the top of the pot body 1. A feed inlet 11 is provided on one side of the pot body 1, and a discharge outlet 12 is provided on the other side. In another possible embodiment, the pot body 1 has a shared opening for both feeding and discharging on only one side.

[0034] Two turntables 3 are coaxially mounted inside the pot body 1, located at opposite axial ends of the pot body 1. The peripheral edges of the turntables 3 are clearance-fitted with the pot body 1, meaning the diameter of the turntables 3 is slightly smaller than the inner diameter of the pot body 1. A drive shaft 13 is coaxially fixed to each turntable 3, extending to the outer side of the pot body 1. The two drive shafts 13 are connected to the same drive source and can rotate synchronously at the same speed and in the same direction, thus driving the two turntables 3 to rotate synchronously. When a separate design of the two drive shafts 13 is used, no other shafts are needed to connect the two turntables 3, allowing for a larger scalding space within the pot body 1. In another possible implementation, the two drive shafts 13 are coaxially mounted (i.e., using an integrated shaft), so only one end of the drive shaft 13 is connected to the drive source, simplifying the transmission structure.

[0035] One to three levers 5 are positioned between two turntables 3. A swing shaft 51 is fixedly mounted on the side of each lever 5 near the circumferential edge of the turntable 3. The swing shaft 51 is parallel to the central axis of the turntable 3. When two or three levers 5 are provided, the swing shafts 51 are evenly distributed along the circumferential edge of the turntable 3. Both ends of the swing shaft 51 are rotatably connected to the adjacent turntable 3, and after passing through the turntable 3, the swing shaft 51 is fixedly connected to the first end of a fixed arm 52. The levers 5 are provided with water passage holes. The fixed arm 52 is positioned between the turntable 3 and the axial end face of the adjacent pot body 1. Figures 3-5 In the embodiment, two levers 5 are provided, and two swing shafts 51 are evenly distributed on the circumferential edge of the turntable 3. The central axis of the two swing shafts 51 is coplanar with the central axis of the turntable 3.

[0036] A cam groove 4 is fixedly provided in the axial end face of the pot body 1. A roller 54 is fixedly provided at the second end of the fixed arm 52. The roller 54 is located in the cam groove 4 and is slidably connected with the cam groove 4. Therefore, the roller 54 can slide along the cam groove 4.

[0037] The cam slide 4 includes an arc segment 41 and a variable diameter segment 42 with a reduced radius. The radial direction of the minimum radius of the variable diameter segment 42 faces downwards from the discharge port 12. The arc segment 41 and the variable diameter segment 42 are connected by a transition surface.

[0038] like Figure 5The diagram shows the motion state of this embodiment. When the roller 54 slides from the arc section 41 into the variable diameter section 42, the radial deflection angle of the lever 5 (the angle between the plane containing the central axis of the swing shaft 51 and the central axis of the turntable 3 and the lever 5) gradually decreases, and when the roller 54 slides from the variable diameter section 42 into the arc section 41, the radial deflection angle of the lever 5 gradually increases.

[0039] In this embodiment, the lower half of the pot 1 is filled with hot water, and the poultry to be scalded is put in through the feed inlet 11. During scalding, the turntable 3 rotates counterclockwise, and the paddle plate 5 moves the poultry in the hot water. When the paddle plate 5 moves towards the feed inlet 11, the roller 54 gradually slides from the variable diameter section 42 into the arc section 41, and the radial deflection angle of the paddle plate 5 gradually increases, making it easier for the poultry on the paddle plate 5 to slide into the hot water. After scalding is completed, the turntable 3 rotates clockwise, and the paddle plate 5 moves the poultry in the hot water. When the paddle plate 5 moves towards the discharge outlet 12, the roller 54 gradually slides from the variable diameter section 42 into the arc section 41, and the radial deflection angle of the paddle plate 5 gradually increases, making it easier for the poultry on the paddle plate 5 to slide into the discharge outlet 12.

[0040] In this embodiment, the poultry carcass is placed between the two turntables 3. The turntables 3 can isolate the poultry carcass from the fixed arm 52, preventing the fixed arm 52 from squeezing the poultry carcass when it swings. In another possible implementation, the opposite sides of the two turntables 3 are both convex cones. When the sides of the turntables 3 are frustoconical or conical, their strength can be improved and the sides are not easily deformed.

[0041] In another possible implementation, a bearing or sleeve is fitted around the outside of the roller 54, and the bearing or sleeve is disposed within the cam groove 4. The bearing or sleeve improves the smoothness of the roller 54's sliding. Preferably, the bearing is a ceramic bearing.

[0042] Example 2: The poultry scalding device provided in this example has the following main improvements compared to Example 1: 1-2 connecting rods 53 are sequentially hinged to the second end of the fixed arm 52, and the roller 54 is set on the last connecting rod 53. By setting the connecting rods 53, the size of the cam groove 4 can be reduced.

[0043] like Figures 6-7 A poultry scalding device with two connecting rods 53 is shown. A roller 54 is provided on the connecting rod 53 away from the fixed arm 52 (i.e., the last connecting rod 53), and the roller 54 is located in the cam groove 4. At the same time, the end of the connecting rod 53 away from the fixed arm 52 is also rotatably connected to the turntable 3.

[0044] Figure 8 The diagram shows the motion state of the poultry scalding device with two connecting rods 53. Its motion state and motion effect are basically the same as those in Example 1, and will not be described again.

[0045] Example 3: See Figures 9-10 The poultry scalding device provided in this embodiment has been improved in the following ways compared with Embodiment 1 or Embodiment 2: the main body of the cam slide 4 in Embodiment 1 or Embodiment 2 is a groove rail structure, such as... Figure 9 As shown, the main body of the cam slide 4 in this embodiment is a groove plate structure.

[0046] like Figure 10 As shown, when the main body of the cam slide 4 is a groove plate, the bearing seat of the drive shaft 13 can be directly fastened to the groove plate during installation, and the bearing seat and the groove plate will be more secure.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
