[0002] In the prior art, such as in an automatic feeding and discharging device and method for a freeze drying tray on a freeze dryer with the patent number CN118229189A, the freeze drying tray is flipped through a feeding and discharging assembly, so as to directly convey the freeze dried product into a storage container in the freeze drying chamber and then take it out, thereby improving the efficiency of automatic feeding and discharging during the freeze drying process. However, the applicant has been engaged in the processing of pet freeze dried food for a long time and found that there are at least the following defects in the prior art:

[0003] 1. Freeze drying is carried out by sublimating moisture after freezing, resulting in some freeze dried products being easily adhered to the freeze drying tray after drying.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0043] Referring to Figures 1-8 , the present invention provides an automatic feeding and discharging device for pet freeze-drying, including:

[0044] A freeze dryer 1, inside which a number of freeze-drying chambers 101 are successively defined vertically;

[0045] A feeding and discharging mechanism, including a conveying tray detachably connected inside the freeze-drying chamber 101, on which a conveyor belt 2 is movably fitted. A driving member is provided inside the freeze dryer 1, and the driving end of the driving member is connected to the conveyor belt 2 so that the conveyor belt 2 can move in the direction of leading to or entering the freeze-drying chamber 101. The top surface of the conveyor belt 2 is used for placing pet freeze-dried products;

[0046] A door panel 3, rotatably connected to the front end surface of the freeze dryer 1, used to block a number of freeze-drying chambers 101. A number of unit doors 301 are provided on the door panel 3, and the unit doors 301 are arranged in one-to-one correspondence with the freeze-drying chambers 101. When the unit door 301 is opened, pet freeze-dried products can be sent out or put into the conveyor belt 2;

[0047] A baffle 4, elastically connected to the inner bottom surface of the freeze-drying chamber 101 near the side of the unit door 301, and the baffle 4 is in sliding contact with the outer side wall of the conveyor belt 2.

[0048] In the present invention, a number of freeze-drying chambers 101 are defined in a freeze-dryer 1, and a conveying tray is detachably placed corresponding to each freeze-drying chamber 101, so that in each freeze-drying chamber 101, the conveyor belt 2 is driven by a driving member to be separately sent out or into, the prepared pet freeze-dried products are sent out, or the pet freeze-dried products to be freeze-dried are replenished again, thereby improving the automatic feeding and discharging efficiency of the pet freeze-dried products. Correspondingly, a unit door 301 is correspondingly arranged on the door panel 3, and the opening and closing of the freeze-drying chamber 101 are controlled through the unit door 301. When the unit door 301 is opened, the pet freeze-dried products are taken out or replenished as needed. When the unit door 301 is closed, the freeze-dryer 1 performs refrigeration and drying on the inside of the freeze-drying chamber 101.

[0049] In addition, a baffle 4 elastically connected in the freeze-drying chamber 101 is in sliding contact with the conveyor belt 2. After the pet freeze-dried products are prepared, the driving member controls the conveyor belt 2 to rotate, and the pet freeze-dried products are conveyed along the direction of the unit door 301. The baffle 4 is used to scrape the surface of the conveyor belt 2 to reduce the adhesion of the pet freeze-dried products and reduce the waste generated during feeding and discharging.

[0050] Specifically, the inner cavity of the overall freeze-dryer 1 is sealed by the door panel 3. Before starting refrigeration and drying, the door panel 3 can be opened to put a number of conveying trays into a number of freeze-drying chambers 101 one by one, and the freeze-drying chambers 101 are detachably connected to the conveying trays to fix them. As the freeze-drying progresses, after the pet freeze-dried products in a certain freeze-drying chamber are prepared first, the corresponding unit door 301 is directly opened, and then the driving member drives the conveyor belt 2 for discharging and transporting. As the conveyor belt 2 continuously rotates, until there are no pet freeze-dried products on the top surface of the conveyor belt 2, the driving member controls the conveyor belt 2 to reverse, so as to put new freeze-dried products to be dried into the freeze-drying chamber 101 along the unit door 301.

[0051] Furthermore, the conveying tray includes a pair of support plates 5 distributed oppositely. A rotating shaft 6 is respectively connected between the two sides of the pair of support plates 5. The conveyor belt 2 is sleeved on the two rotating shafts 6. The driving member is connected to one rotating shaft 6 at the front end of the freeze-drying chamber 101, and a lifting member is arranged at the rear end of the freeze-drying chamber 101. The lifting end of the lifting member is connected to the adjacent other rotating shaft 6, so that the conveyor belt 2 rotates and lifts around the front end of the freeze-drying chamber 101.

[0052] The rotating shaft 6 is lifted by the lifting member, so that the conveyor belt 2 rotates and lifts by a certain angle, and the top surface of the conveyor belt 2 is inclined along the front end surface of the freeze-drying chamber 101, thereby improving the efficiency of the conveyor belt 2 for sending out the pet freeze-dried products.

[0053] The conveyor belt 2 is sleeved on the two rotating shafts 6, and the driving member drives the rotating shaft 6 at the front end to rotate, so as to directly drive the overall conveyor belt 2 to rotate and convey.

[0054] A handle is fixedly connected to the top surface of the support plate 5, which is convenient for the staff to pick up and place the conveying tray.

[0055] Further, the driving member includes: a first motor 7 fixedly connected to the outer wall surface of the freeze dryer 1, a first driving rod 8 fixedly connected to the output shaft of the first motor 7, an embedding groove is formed at the bottom end of the support plate 5, and the first driving rod 8 penetrates through the embedding groove and extends into the freeze drying chamber 101; a driving gear 9 sleeved and fixedly connected to the part of the first driving rod 8 extending into the freeze drying chamber 101, and the driving gear 9 is rotatably connected to the front end of the freeze drying chamber 101. A rotating rod 11 is coaxially fixedly connected to the rotating shaft 6 adjacent to the driving gear 9, a driven gear 10 is sleeved and fixedly connected to the rotating rod 11, the driven gear 10 meshes with the driving gear 9, and the rotating rod 11 is rotatably connected to the support plate 5.

[0056] The first motor 7 is used to rotate the driving gear 9, and the driving gear 9 meshes with the driven gear 10, so as to drive the rotating shaft 6 located at the front end to rotate. Moreover, the driving gear 9 and the driven gear 10 are connected by the weight of the support plate 5 and the conveyor belt 2, as well as the detachable connection of the freeze drying chamber 101 to the conveying tray, so as to ensure the tight meshing between the driving gear 9 and the driven gear 10 and ensure the driving effect on the conveyor belt 2.

[0057] By forming an embedding groove on the support plate 5 and embedding the first driving rod 8 in the embedding groove, the limit of the support plate 5 is formed, and the connection stability between the conveying tray and the freeze drying chamber 101 is improved.

[0058] Further, the lifting member includes:

[0059] a lifting plate 12, one end of which is rotatably connected to the inner bottom surface of the freeze drying chamber 101 through a hinge shaft 13. A first air cylinder 14 is hinged to the inner bottom surface of the freeze drying chamber 101, and the piston end of the first air cylinder 14 is hinged to the lifting plate 12;

[0060] a limiting shaft 15 rotatably connected coaxially with the rotating shaft 6 near the rear end of the freeze drying chamber 101. A limiting groove is formed on the inner side wall of the support plate 5, and the limiting shaft 15 is slidably connected with the limiting groove. The top surface of the lifting plate 12 abuts against the part of the limiting shaft 15 extending out of the limiting groove.

[0061] The first air cylinder 14 expands and contracts to rotatably support the lifting plate 12, and the lifting plate 12 rotates relative to the freeze drying chamber 101 around the hinge shaft 13. Since the limiting shaft 15 is fixedly connected to the rotating shaft 6 located at the rear end and the lifting plate 12 abuts against the limiting shaft 15, the conveyor belt 2 is driven to rotate and lift. In this technical solution, by forming a limiting groove on the support plate 5, during the process of the limiting shaft 15 rotating and lifting, the distance between the limiting shaft 15 and the rotating shaft 6 located at the front end remains fixed, and the stability during the rotation and lifting of the conveyor belt 2 is maintained.

[0062] It can be understood that the limiting groove is an arc-shaped structure centered on the front-end rotating shaft 6. When the limiting shaft 15 is slidably limited in the limiting groove, the distance between the rotating shafts 6 respectively arranged at the front end and the rear end remains unchanged, so as to provide a stable rotating support for the conveyor belt 2.

[0063] Further, it further includes:

[0064] Partition plates 16 are fixedly connected inside the freeze dryer 1. There are several partition plates 16. The several partition plates 16 cooperate to divide out several freeze-drying chambers 101. A chute is opened at the front end of the top surface of the partition plate 16 close to the freeze-drying chamber 101. The baffle 4 is slidably connected in the chute. The two ends of a spring 17 are respectively fixedly connected to the bottom end of the baffle 4 and the inner wall of the bottom end of the chute. Several springs 17 are arranged along the width direction of the partition plate 16.

[0065] By fixedly connecting the partition plates 16 inside the freeze dryer 1, several freeze-drying chambers 101 are divided out. A chute is opened on the partition plate 16. By fixedly connecting the spring 17 between the partition plate 16 and the baffle 4, the baffle 4 is elastically and slidably connected to the partition plate 16. When placing the conveying tray, press down the baffle 4 and then directly push the conveying tray into the freeze-drying chamber 101 along the inner side, which improves the working efficiency.

[0066] Further, clamping plates 18 are respectively fixedly connected to both sides of the baffle 4. Card slots are opened on the top surface of the partition plate 16. The clamping plates 18 are slidably connected in the card slots in the vertical direction. The support plate 5 is clamped between the clamping plates 18 and the rear side wall surface of the freeze-drying chamber 101. The clamping plates 18 are in sliding contact with the support plate 5.

[0067] By fixedly connecting the clamping plates 18 to both sides of the baffle 4, the spring 17 provides elastic support for the baffle 4 and the clamping plates 18. A clamping and holding structure is formed between the clamping plates 18 and the inner side wall of the freeze-drying chamber 101, and the front and rear ends of the support plate 5 are clamped and fixed correspondingly. When it is necessary to move the support plate 5, press down the baffle 4 to drive the clamping plates 18 to extend into the card slots, which realizes the detachable connection of the conveying tray.

[0068] Further, several through slots are opened on the door panel 3. The unit door 301 is arranged in the through slots. The top surface height of the conveyor belt 2 is lower than the height of the top inner wall of the through slots. A control member is arranged on the door panel 3. The control end of the control member is connected to the unit door 301. Specifically, when the conveyor belt 2 is in a horizontal state, the top surface height of the conveyor belt 2 is lower than the top inner wall of the through slots. When the lifting plate 12 rotates and lifts the conveyor belt 2, the rear end height of the conveyor belt 2 is higher than the top inner wall of the through slots.

[0069] Further, a transfer slot is opened at the top of the through slot. A support plate 20 is transferred in the transfer slot. The bottom end of the support plate 20 is fixedly connected to the top surface of the unit door 301. The control member includes a second motor 19 fixedly connected inside the door panel 3. A second driving rod 21 is fixedly connected to the output shaft of the second motor 19. The second driving rod 21 is fixedly connected to one side of the support plate 20.

[0070] The second motor 19 is used to rotate the second drive rod 21, and the second drive rod 21 rotates the support plate 20, thereby flipping the unit door 301 to control the opening and closing of the through groove. When the through groove is opened, the first motor 7 rotates the rotating shaft 6 to convey the pet freeze-dried products along the direction towards the unit door 301 by the conveyor belt 2, realizing the discharging of the pet freeze-dried products. When feeding the pet freeze-dried products, if refrigeration is not carried out, the overall door panel 3 can be opened, and the freeze-dried products are laid on the top surface of the conveying tray. After starting the refrigeration, the freeze-dried products can be directly placed on the top surface of the conveyor belt 2 along the width direction of the freeze-drying chamber 101 corresponding to the through groove. As the conveyor belt 2 moves in the reverse direction, the freeze-dried products are sent into the freeze-drying chamber 101, reducing the waste of resources and improving the feeding and discharging efficiency.

[0071] Furthermore, it further includes:

[0072] A lifting platform 22 is placed outside the freeze-dryer 1. The bottom end of the lifting platform 22 is fixedly connected with a second cylinder 23. An opening is formed on one side of the lifting platform 22 close to the door panel 3, and the lifting platform 22 can communicate with any one of a plurality of unit doors 301.

[0073] A controller 24 is fixedly connected to the rear side of the freeze-dryer 1. A plurality of evaporators 25 are arranged in the freeze-dryer 1. The number of evaporators 25 is the same as that of the freeze-drying chambers 101 and they are in one-to-one correspondence. The controller 24 is communicatively connected with the plurality of evaporators 25.

[0074] The second cylinder 23 is used to drive the lifting platform 22 to move up and down, so that the lifting platform 22 communicates with the freeze-drying chamber 101 from which the pet freeze-dried products are discharged. On the basis of the feeding of the conveyor belt 2, the pet freeze-dried products are sent out of the freeze-dryer 1.

[0075] The controller 24 and the evaporator 25 are common devices of the freeze-dryer 1, which cooperate with the condenser and the compressor for heat exchange refrigeration to realize freeze-drying. This is a conventional technology and will not be elaborated too much.

[0076] Furthermore, a plurality of observation windows 26 are arranged along the vertical direction on one side of the freeze-dryer 1 adjacent to the door panel 3. The number of observation windows 26 is the same as that of the freeze-drying chambers 101 and they are in one-to-one correspondence.

[0077] By arranging a plurality of observation windows 26 on the side wall of the freeze-dryer 1, it is convenient to observe the environment for preparing the freeze-dried products in the freeze-drying chamber 101.

[0078] The working principle of the automatic feeding and discharging device for pet freeze-dried products of the present invention:

[0079] Open the door panel 3, sequentially place the conveying trays along a plurality of freeze-drying chambers 101. After pressing down the baffle until the sliding support plate 5 abuts against the inner wall of the freeze-drying chamber 101, the baffle 4 loses the pressing force, and the baffle 4 is bounced up by the spring 17, driving the clamping plate 18 to clamp the support plate 5. By rotating the driven gear 10 to make the driven gear 10 engage with the driving gear 9, the placement of the conveying tray can be completed.

[0080] Place the freeze-dried pet food on the top surface of the conveyor belt 2, close the door panel 3, and start the evaporator 25 to refrigerate by the controller 24 to refrigerate and dry the freeze-dried pet food. Observe the freeze-drying state through the observation window 26, and combine with the refrigeration time to judge the degree of freeze-drying preparation. After the preparation is completed in a certain freeze-drying chamber 101, the controller 24 closes the corresponding evaporator 25, and at the same time starts the second motor 19. The second motor 19 rotates the unit door 301 to open it, and the partition 16 can isolate the refrigeration temperature so that the refrigeration and drying can continue in the remaining freeze-drying chambers 101. Start the first motor 7 to drive the driving gear 9 to rotate, and the first cylinder 14 rotates and lifts the lifting plate 12. The lifting plate 12 supports the conveyor belt 2 to rotate around the front shaft 6, and under the transportation of the conveyor belt 2, the freeze-dried pet food exits the freeze-dryer 1 towards the unit door 301. Use the baffle 4 to slide contact with the conveyor belt 2 to fully separate the freeze-dried food from the conveyor belt 2, and the second cylinder 23 lifts the lifting platform 22 to use the lifting platform 22 to receive the freeze-dried pet food that exits the freeze-dryer 1.

[0081] Finally, control the first motor 7 to reverse and lower the lifting plate 12 to the horizontal position. The staff can stack the freeze-dried food to be refrigerated on the conveyor belt 2 along the direction of the unit door 301. The freeze-dried food is automatically sent into the freeze-drying chamber 101 through the conveyor belt 2. And in order to ensure that the freeze-dried food can be evenly placed on the conveyor belt 2 during the feeding process, the start and stop of the first motor 7 can be controlled so that the side of the conveyor belt 2 close to the unit door 301 is transported into the freeze-drying chamber 101 after the freeze-dried food is evenly placed, realizing the preparation of freeze-dried pet food without stopping the machine and realizing automatic feeding and discharging production.
