Description

Technical Field

[0001] The utility model relates to the field of pre-prepared food preparation, in particular to a pre-prepared food sampling and detection device. Background Art

[0002] Pre-prepared food refers to a cost-effective or semi-finished product made from various agricultural, livestock, poultry, and aquatic products as raw materials and auxiliary materials such as seasonings, which are processed through pre-selection, modulation, and other processes. It is stored and sold under cold chain conditions for consumers to eat after simple heating or cooking. In the prior art, due to the large number and variety of pre-prepared food, in order to meet the mass production of pre-prepared food, it is necessary to adopt an assembly line processing method for rapid production.

[0003] After processing, pre-prepared dishes need to be filled in cans for storage, and samples need to be taken during the storage process to determine whether the dishes have deteriorated. However, the sampling process requires manual operation and it is inconvenient to pick up the dishes during sampling, which makes the sampling process cumbersome and there is no protection for the dishes, which can easily lead to impurities entering the food. Utility Model Content

[0004] The utility model aims to provide a pre-prepared food sampling and detection device to solve the problems in the prior art that the pre-prepared food cannot be quickly sampled during storage and the sampling process is cumbersome.

[0005] In order to solve the above problems, the pre-prepared food sampling and detection device involved in the utility model adopts the following technical solutions:

[0006] The pre-prepared food sampling and detection device comprises a storage tank, a sampling port is arranged on the side wall of the storage tank, the sampling port is arranged obliquely, a sleeve for inserting into the storage tube is sealed and inserted at the sampling port, the inner end of the sleeve is blocked with a one-way sealing plate, one end of the one-way sealing plate is hingedly assembled with the sleeve, and a torsion spring is connected between the two for applying a force to the one-way sealing plate to move toward the inner port so as to seal the one-way sealing plate on the inner port of the sleeve; the sampling and detection device also comprises a sampling tube inserted in the sleeve, the sampling tube is rotatably assembled in the sleeve, and the sampling tube is inserted in the sleeve. The front end of the sample tube has a sampling part and the rear end has a rotating part. The sampling part includes a sampling head with an inner cavity. A sampling groove is opened on the side wall of the sampling head. The rear end of the sampling head is sleeved with a rubber sleeve. The rubber sleeve is sealed and fitted with the inner wall of the sleeve to seal the annulus between the sampling tube and the sleeve. After the sampling tube is inserted into the sleeve, the one-way sealing plate can be pushed forward to open the one-way sealing plate to be inserted into the tank, and the food in the tank can be poured into the sampling sleeve after rotating at a set angle; the outer diameter of the rubber sleeve is smaller than the outer diameter of the rear end of the sleeve so that the sampling tube can move freely out of the sleeve when it moves backward.

[0007] Furthermore, the front end of the sampling head is also provided with a rubber head for pushing open the one-way sealing plate, and the outer diameter of the rubber head is consistent with the inner diameter of the sleeve.

[0008] Furthermore, an air supply port for connecting the front side of the rubber sleeve and the rear end of the sleeve is also provided on the inner side wall of the front end of the sleeve.

[0009] Furthermore, an intermediate sleeve is rotatably assembled inside the rear port of the sleeve, the interior of the intermediate sleeve is a square hole, the exterior of the intermediate sleeve is rotatably assembled with the rear end of the sleeve, and the side wall of the sampling tube has a square protrusion that fits and engages with the square hole.

[0010] Furthermore, a sealing sleeve is connected to the rear end of the sleeve, and the sealing sleeve is fixedly connected to the outer side wall of the sleeve through an external nut to achieve locking, and the intermediate sleeve is rotatably assembled inside the sleeve.

[0011] Furthermore, the rotating portion includes a welding nut fixedly connected to the rear end of the square protrusion.

[0012] Furthermore, the sampling tube is provided with an exhaust port which passes through the rear end of the sampling tube and the inner cavity of the sampling head from front to back.

[0013] The beneficial effects of the utility model are as follows: when the pre-prepared food sampling device is actually used, when it is necessary to sample the food in the can, the worker directly inserts the sampling tube into the sleeve, the sampling tube pushes the one-way sealing plate to open, and then rotates the sampling tube. The food flows into the inner cavity of the sampling head under pressure to complete the sampling, and then the sampling tube is pulled out. At this time, the one-way sealing plate gradually closes the front end of the sleeve, and the rubber sleeve and the sleeve are sealed to prevent food from entering the sleeve, thereby ensuring that there is no leakage of food. The structure is simple, sampling is convenient, and the operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the technical purpose, technical solution and beneficial effects of the utility model clearer, the technical solution of the utility model is further described below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0022] The specific embodiment of the pre-prepared food sampling and detection device involved in the utility model is as follows: Figures 1 to 5 As shown, the pre-prepared food sampling and detection device includes a storage tank 1, which has a filling port on the top and a discharge port on the bottom. In order to facilitate sampling, a sampling port 2 is provided on the side wall of the storage tank 1, and the sampling port 2 is gradually tilted outward from bottom to top. A sleeve 3 for inserting into the storage tube is sealed and inserted at the sampling port 2. The sampling port 2 is relatively welded and fixed to the storage tank 1. In order to meet the installation and later cleaning of the sleeve 3, the sleeve 3 and the sampling port 2 can be disassembled and assembled. Specifically, a ring platform 33 is provided on the outer wall near the rear end of the sleeve 3, which is connected to the sampling port 2 by screws, and a sealing gasket 8 is also installed between the fitting surfaces of the two to ensure the sealing performance.

[0023] At the same time, a one-way sealing plate 7 is sealed at the inner end of the sleeve 3, one end of the one-way sealing plate 7 is hingedly assembled with the sleeve 3, and a torsion spring 31 is connected between the two for applying a force to the one-way sealing plate 7 to move toward the inner port so as to seal the one-way sealing plate 7 on the inner port of the sleeve 3; during normal storage, the one-way sealing plate 7 is always kept in a posture of sealing the rear end of the sleeve 3 due to the force of the torsion spring 31. When sampling is required, the one-way sealing plate 7 is opened outward by pushing from the inside of the sleeve 3. Such a design can prevent food from entering the sleeve 3 from the one-way sealing plate 7.

[0024] The sampling detection device also includes a sampling tube 4 which is guided and inserted into the sleeve 3. The sampling tube 4 is rotatably assembled in the sleeve 3. The front end of the sampling tube 4 has a sampling part and the rear end has a rotating part. The sampling part includes a sampling head 41 with an inner cavity. A sampling groove 45 is provided on the side wall of the sampling head 41. The rear end of the sampling head 41 is sleeved with a rubber sleeve 44. The rubber sleeve 44 is sealed and fitted with the inner wall of the sleeve 3 to block the annulus between the sampling tube 4 and the sleeve 3. After the sampling tube 4 is inserted into the sleeve 3, it can push the one-way sealing plate 7 forward to open the one-way sealing plate 7 to be inserted into the tank, and after rotating to a set angle, the food in the tank is poured into the sampling sleeve; the outer diameter of the rubber sleeve 44 is smaller than the outer diameter of the rear end of the sleeve 3 so that the sampling tube 4 can move freely out of the sleeve 3 when it retreats backward.

[0025] Specifically, the structure of the sampling head 41 is as follows Figure 5 As shown, the front end of the sampling head 41 is also provided with a rubber head 43 for pushing open the one-way sealing plate 7, and the outer diameter of the rubber head 43 is consistent with the inner diameter of the sleeve. At the same time, an exhaust hole 46 is opened between the inner cavity of the sampling head 41 and the rear end of the sampling tube 4.

[0026] During the sampling operation, the front end of the sampling head 41 moves forward, pushes open the one-way sealing plate 7, and is inserted into the storage tank 1. When inserted to the limit position, the rubber head 43 and the sampling head 41 are outside the sleeve 3, and the rubber sleeve 44 is inside the front end of the sleeve 3, so that it can always ensure that no food enters the sleeve 3. Afterwards, in order to facilitate the entry of food into the inner cavity of the sampling head 41, the sampling tube 4 is directly rotated, and the food at the corresponding height position in the tank flows into the sampling head 41 through its own pressure to complete the sampling. The exhaust hole 46 is designed to prevent the residual air in the sampling head 41 from affecting the entry of food into the sampling head 41, and the air is discharged from the exhaust port to the outside through the food squeeze.

[0027] After sampling is completed, the sampling tube 4 is pulled out backwards. In this process, the one-way sealing plate 7 is gradually buckled on the rear end of the sleeve 3 by the force of the torsion spring 31 to complete the blocking. In the process of pulling the sampling head 41 backwards, in order to avoid negative pressure between the one-way sealing plate 7 and the sampling head 41, it is more preferred that an air replenishment port 32 for connecting the front side of the rubber sleeve 44 and the rear end of the sleeve 3 is further provided on the inner side wall of the front end of the sleeve. External air can enter the front end of the sleeve 3 through the side wall of the sleeve 3 to achieve air replenishment and ensure smooth removal of the sampling tube 4.

[0028] In order to satisfy the rotation of the sampling tube 4 in the sleeve 3, the rear port of the sleeve 3 is rotatably assembled with an intermediate sleeve 5, the interior of the intermediate sleeve 5 is a square hole, the exterior of the intermediate sleeve 5 is rotatably assembled with the rear end of the sleeve 3, and the side wall of the sampling tube 4 has a square protrusion 47 that fits with the square hole. At the same time, in order to facilitate assembly and subsequent replacement and cleaning operations, the rear end of the sleeve 3 is connected with a sealing sleeve 6, which is fixedly connected to the outer wall of the sleeve 3 through an external nut 34 to achieve locking, and the intermediate sleeve 5 is rotatably assembled inside the sleeve 6.

[0029] Preferably, the rotating portion includes a welding nut 42 fixedly connected to the rear end of the square protrusion 47 .

[0030] Finally, it should be noted that the above embodiments are only used to illustrate but not limit the technical solutions of the present utility model. Any equivalent substitutions of the present utility model and any modifications or partial substitutions that do not deviate from the spirit and scope of the present utility model should be included in the scope of protection of the claims of the present utility model.
