Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and specifically to a shovel-type food demoulding mechanism. Background Art

[0002] After baking and processing foods such as mooncakes and bread, it is necessary to demould the foods placed on the trays. Demoulding means taking out the foods on the trays so that the demoulded foods can be transferred to another device and enter the next process. For example, they are transferred to a fermentation rack to enter the fermentation process. For the existing food demoulding, many are directly completed manually, that is, workers use their hands to take out the foods from the trays and put them into another device. This method has low efficiency, high labor costs, and since the foods come directly from the baking process and are still at a relatively high temperature, they are likely to scald the hands of workers, presenting potential safety hazards.

[0003] In addition, in some existing food demoulding devices, due to structural design reasons, there are situations where foods cannot be effectively demoulded completely. That is, during the demoulding process of all foods, a part of the foods remains undemoulded and still stays on the trays. The existing food demoulding devices also include methods such as flipping, vibrating / shaking, etc. to achieve demoulding, but the demoulding effect is poor and it is easy to damage the foods. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a shovel-type food demoulding mechanism, which can solve the problems described in the background art.

[0005] The technical solution for achieving the purpose of the present invention is: a shovel-type food demoulding mechanism, including a frame, as well as a feeding mechanism, a discharging mechanism, and a driving mechanism installed on the frame. The feeding mechanism and the discharging mechanism are both connected to the driving mechanism. The driving mechanism is used to provide power to the feeding mechanism and the discharging mechanism so that the feeding mechanism and the discharging mechanism can achieve transmission.

[0006] One end of the feeding mechanism away from the discharging mechanism is higher than the end close to the discharging mechanism, so that the feeding mechanism conveys the tray carrying the foods in an inclined downward direction towards the discharging mechanism. One end of the discharging mechanism away from the feeding mechanism is higher than the end close to the feeding mechanism, so that it can receive the foods on the tray from the feeding mechanism and convey them out in an inclined upward direction. The conveying speed of the discharging mechanism for the foods is greater than the conveying speed of the feeding mechanism for the foods.

[0007] Furthermore, both the feeding mechanism and the discharging mechanism are inclined towards each other, forming an included angle, and the junction of the two is exactly at the lowest position. The conveying speed of the discharging mechanism is 1.5 to 3 times the conveying speed of the feeding mechanism.

[0008] Furthermore, the feeding mechanism includes a first cross bar, a second cross bar and a plurality of chains. The first cross bar and the second cross bar are respectively installed at both ends along the axial direction of the machine frame, and the first cross bar and the second cross bar span both side ends in the radial direction of the machine frame. Both ends of the chain are respectively wound around the first cross bar and the second cross bar, and the chains are arranged in parallel at intervals. The second cross bar is in transmission connection with the driving mechanism, so that the driving mechanism can drive the second cross bar to rotate, thereby driving the chain wound around the second cross bar to rotate, and thus driving the tray on the chain to be conveyed forward.

[0009] Furthermore, two chains are provided. The two chains are arranged in parallel at intervals and are respectively close to both side ends of the radial machine frame. Both ends of the chain are respectively wound around the first gear and the second gear. The first gear is fixedly installed on the first cross bar, and the second gear is fixedly installed on the second cross bar. Each link of the chain is internally provided with a magnet, and the magnet is used to attract the tray.

[0010] A plurality of ejecting disks are further provided on the second cross bar. Each ejecting disk is fixedly sleeved on the second cross bar at intervals in parallel, and the distance between the two farthest ejecting disks is less than the width of the tray, so that each ejecting disk can support and eject the tray.

[0011] Furthermore, the discharging mechanism includes a roller, a conveyor belt and a shovel assembly. Both ends of the roller are installed at both side ends in the radial direction of the machine frame. The roller is in transmission connection with the driving mechanism, so that the driving mechanism can drive the roller to rotate. Both ends of the conveyor belt are respectively wound around the roller and the shovel assembly and rotate under the rotation of the roller. The shovel assembly is installed on the machine frame and is located at one end close to the feeding mechanism, and the roller is located at the end far from the feeding mechanism. The shovel assembly and the conveyor belt wound around the position of the shovel assembly abut against the tray on the feeding mechanism.

[0012] Among them, the roller is located above the second cross bar and is located above the side of the first cross bar, that is, the height of the roller is higher than the height of the first cross bar, and the height of the shovel is between the first cross bar and the second cross bar, so that both the feeding mechanism and the discharging mechanism are inclined downward towards each other.

[0013] The roller is provided with a first thread, an annular groove and a second thread. The annular groove is arranged at the center of the roller. The first thread and the second thread are symmetrically arranged with respect to the annular groove, and the helix directions of the first thread and the second thread are exactly opposite. By setting two threads with opposite helix directions, it can effectively prevent the conveyor belt wound around the roller from shifting. The first thread, the annular groove and the second thread together play a role in increasing the friction with the conveyor belt, thereby preventing the conveyor belt from shifting.

[0014] Further, the blade assembly is an angle-adjustable blade assembly. The angle-adjustable blade assembly includes a blade, a support plate, a second cylinder, a telescopic rod, a connecting member, a rotating shaft, a column, a hinge, and a connecting plate. The blade and the support plate are connected by a hinge, and the upper surfaces of the blade and the support plate are flush. The conveyor belt is wound around one end of the blade away from the support plate, and the support plate is installed on the frame, thereby installing the blade assembly on the frame.

[0015] The second cylinder is fixedly installed below the support plate through the connecting plate. The connecting plate and the connecting member are fixedly attached to the lower surface of the support plate. The telescopic rod of the second cylinder is fixedly connected to the connecting member. One end of the connecting member away from the telescopic rod is provided with an activity space with an opening, and a rotating shaft passing through the activity space is provided on the connecting member. The rotating shaft is connected to one end of the column, and the column can rotate relative to the rotating shaft within the activity space. The other end of the column is fixedly connected to the lower surface of the blade.

[0016] A plurality of hinges are provided, and each hinge extends axially along the joint of the support plate and the blade, and each hinge is arranged in parallel at intervals.

[0017] The second cylinder is located at the side close to the support plate. The blade includes a transverse portion and a protruding portion. The protruding portion is fixed in the center of the transverse portion and protrudes towards the feeding mechanism. The column is connected to one side of the transverse portion and is away from the protruding portion. One end of the hinge is fixed to the transverse portion, and the other end is fixed to the support plate.

[0018] A number of hollow openings are also dug on the protruding portion, and each hollow opening is arranged in parallel at intervals.

[0019] Further, the blade-type food demolding mechanism further includes a lower support adjustment component and a limit component. The lower support adjustment component is used to adjust the inclination degree of the blade assembly and support the blade assembly. The limit component is used to limit the maximum inclination degree of the blade assembly after the inclination degree is adjusted by the lower support adjustment component. The lower support adjustment component and the limit component are both fixedly installed on the frame and arranged at intervals. The lower support adjustment component is located at one end of the blade assembly away from the roller, and the limit component is located at one end close to the roller.

[0020] Further, the lower support adjustment component includes a first limit wheel, a first rocker arm, a first transmission rod, a base, a bearing, a second rocker arm, and a first cylinder. The first limit wheel is fixedly connected to one side of one end of the first rocker arm close to the blade assembly. The other end of the first rocker arm is in transmission connection with the first transmission rod, so that the rotation of the first transmission rod can drive the first rocker arm to rotate. One end of the first transmission rod passing through the base is also in transmission connection with one end of the second rocker arm. The base is installed on the frame, and the other end of the second rocker arm is connected to the output end of the first cylinder.

[0021] During the telescopic process of the output end of the first cylinder, the second rocker arm is driven to rotate clockwise or counterclockwise. The second rocker arm drives the first rocker arm to rotate clockwise or counterclockwise through the first transmission rod, thereby adjusting the height of the first limiting wheel and thus adjusting the inclination degree of the shovel blade assembly.

[0022] A third rocker arm is also connected to the end of the first transmission rod far from the cylinder. One end of the third rocker arm is sleeved on the first transmission rod, and the other end is connected with a second supporting wheel.

[0023] The limiting assembly includes a handwheel, a lead screw, a sliding seat, a first connecting rod, a second bearing, a fixed seat, a second connecting rod and a first limiting supporting wheel. The handwheel is installed on the frame through a bottom plate. After passing through the bottom plate, the handwheel is connected to the upper end of the lead screw. The lower end of the lead screw passes through the sliding seat, and the sliding seat is connected with the first connecting rod. The first connecting rod is also connected with a transmission shaft through the second bearing. The second bearing is installed on the fixed seat, and the fixed seat is installed on the frame. The transmission shaft is also connected with the second connecting rod, and the second connecting rod is also connected with the first limiting supporting wheel. The first limiting supporting wheel is located below the shovel blade assembly and is used to limit the maximum inclination degree of the shovel blade assembly.

[0024] A third connecting rod and a second limiting supporting wheel are also connected to the other end of the transmission shaft. By driving the transmission shaft to rotate, the second connecting rod and the third connecting rod are synchronously driven to rotate.

[0025] Furthermore, the shovel blade type food demoulding mechanism further includes a speed difference transmission assembly. The driving mechanism is connected with the speed difference transmission assembly, and the speed difference transmission assembly is also connected with the feeding mechanism and the discharging mechanism. The driving mechanism synchronously drives the feeding mechanism and the discharging mechanism to convey through the speed difference transmission assembly, and makes the conveying speed of the discharging mechanism greater than that of the feeding mechanism to form a speed difference.

[0026] The speed difference transmission assembly includes a connecting seat, a main gear, a driven gear, a transmission chain, a fixing piece and a flange group. The main gear is rotatably installed on the outside of the connecting seat. The inside of the connecting seat is connected with one end of the first cross bar. The other end of the first cross bar is connected with the driving mechanism. The driving mechanism is a motor, and the motor is installed on the frame. The other end of the first cross bar is connected with the output end of the motor, so that the motor can drive the first cross bar to rotate, and then drive the main gear to rotate. The two ends of the transmission chain are respectively wound around the main gear and the driven gear. The driven gear is installed on the outside of the fixing piece and can rotate relative to the fixing piece. The fixing piece is connected with a roller through the flange group, and the roller is detachably installed on the fixing piece through the flange group. The fixing piece is installed on the frame.

[0027] Further, the connecting seat includes a connecting plate, a cylinder, an annular cavity, and a connecting through hole. The cylinder is fixedly installed on the outer side of the connecting plate and protrudes outward. The cylinder includes a first circular ring and a second circular ring that are concentric circles. Both the first circular ring and the second circular ring extend and protrude toward the main gear. The second circular ring is located within the first circular ring. An annular cavity is formed between the first circular ring and the second circular ring, which can effectively save materials. The second circular ring penetrates through the connecting plate to form the connecting through hole. The first cross bar passes through the connecting through hole and is connected to the main gear. The main gear is sleeved on the first cross bar, and the main gear is spaced from the connecting seat.

[0028] The fixing member includes a bottom plate, a sleeve, a limiting ring, and a connecting column. The sleeve and the connecting column are fixedly connected to the end surface of the bottom plate on the side close to the driven gear. The bottom plate is fixedly installed on the frame. The sleeve is sleeved on the connecting column. The connecting column passes through the bottom plate and is fixedly connected to the flange group. The driven gear is sleeved on the connecting column and is located between the sleeve and the limiting ring. The driven gear is spaced from both the sleeve and the limiting ring. The driven gear drives the connecting column to rotate, and the connecting column drives the roller to rotate through the flange group, thereby driving the conveyor belt on the roller to convey.

[0029] The flange group includes a first connecting cylinder, a second connecting cylinder, a first flange, and a second flange. The first flange is fixed to one end of the first connecting cylinder, and the second flange is fixed to one end of the second connecting cylinder. The first flange and the second flange are attached together and fixedly connected together. The second connecting cylinder is fixedly connected to the connecting column.

[0030] The beneficial effects of the present invention are as follows: The present invention can well realize food conveying, and avoid using conveying methods such as shaking or flipping that are likely to affect the food. Moreover, the angle can be adjusted according to the tray situation (for example, just a flat tray and a tray with a border), so as to better convey the food in the tray according to the tray situation. The entire mechanism realizes stable and efficient food conveying, can adapt to different tray scenarios, has a larger adaptation range, better demolding effect, and higher efficiency.

Detailed implementation manner

[0047] The following further describes the present invention in conjunction with the attached drawings and specific implementation schemes:

[0048] As Figures 1 - 15 shown, a food 4 demoulding mechanism with a shovel knife 53 includes a frame 2, as well as a feeding mechanism, a discharging mechanism and a driving mechanism installed on the frame 2. The feeding mechanism and the discharging mechanism are both connected to the driving mechanism, and the driving mechanism is used to drive the feeding mechanism and the discharging mechanism to rotate, so as to enable the feeding mechanism and the discharging mechanism to achieve transmission by providing power to the feeding mechanism and the discharging mechanism. One end of the feeding mechanism away from the discharging mechanism is higher than the end close to the discharging mechanism, so that the feeding mechanism conveys the food 4 on the tray 3 in an inclined downward direction towards the discharging mechanism, and one end of the discharging mechanism away from the feeding mechanism is higher than the end close to the feeding mechanism, so as to receive the food 4 on the tray 3 from the feeding mechanism and move it out in an inclined upward direction. The speed of the discharging mechanism for conveying the food 4 is greater than the speed of the feeding mechanism for conveying the food 4, so as to prevent the food 4 from piling up at the joint of the feeding mechanism and the discharging mechanism during the process of the discharging mechanism receiving the food 4 on the tray 3 of the feeding mechanism.

[0049] As Figure 1As shown in the figure, the feeding mechanism and the discharging mechanism are both inclined towards each other, forming an included angle between them, and the joint of the two is exactly at the lowest position. The tray 3 carrying the food 4 is conveyed forward in a downward-sloping manner under the conveyance of the feeding mechanism and approaches the discharging mechanism. When it reaches the joint with the discharging mechanism, one end of the discharging mechanism close to the feeding mechanism abuts against the tray 3. During the continuous forward conveyance of the tray 3 following the feeding mechanism, the food 4 on the tray 3 is moved into the discharging mechanism. Then, under the conveyance of the discharging mechanism, the food 4 is conveyed forward in an upward-sloping manner and moves away from the feeding mechanism. Thus, under the conveyance of the discharging mechanism, the food 4 is removed from the production line or moved into the next process.

[0050] One end of the discharging mechanism close to the feeding mechanism abuts against the tray 3. And when there is a conveying speed difference between the feeding mechanism and the discharging mechanism, the discharging mechanism moves the food 4 on the tray 3 onto the discharging mechanism in the manner of a scraper 53, avoiding the demolding of the food 4 from the tray 3 by means of flipping, vibrating / shaking, etc. It is more efficient and safer, and can avoid damaging the food 4. In actual use, it is also feasible that one end of the discharging mechanism close to the feeding mechanism is close to abutting against the tray 3, that is, there is a very small gap between one end of the discharging mechanism close to the feeding mechanism and the tray 3. Although they are not in contact, this very small gap is not enough to prevent the food 4 from moving onto the discharging mechanism, that is, the food 4 can quickly move through this gap and into the discharging mechanism, so that the discharging mechanism can smoothly receive the food 4 on the tray 3 from the feeding mechanism.

[0051] Among them, the conveying speed of the discharging mechanism is greater than that of the feeding mechanism, which can effectively prevent the food 4 from accumulating at the joint of the feeding mechanism and the discharging mechanism.

[0052] Preferably, the conveying speed of the discharging mechanism is 1.5 times to 3 times that of the feeding mechanism.

[0053] The feeding mechanism includes a first cross bar 8, a second cross bar 17 and a number of chains. The chains are endless chains 1. The first cross bar 8 and the second cross bar 17 are respectively installed at both ends along the axial direction of the frame 2, and the first cross bar 8 and the second cross bar 17 span both side ends in the radial direction of the frame 2. Both ends of the chains are respectively wound around the first cross bar 8 and the second cross bar 17, and the chains are arranged in parallel at intervals. The second cross bar 17 is in transmission connection with the driving mechanism, so that the driving mechanism can drive the second cross bar 17 to rotate, thereby driving the chains wound around the second cross bar 17 to rotate, and thus can drive the tray 3 on the chains to be conveyed forward.

[0054] In this embodiment, two chains are provided, and the two chains are arranged in parallel at intervals and are respectively close to both side ends of the radial frame 2.

[0055] Preferably, both ends of the chain are respectively wound around the first gear and the second gear. The first gear is fixedly installed on the first cross bar, and the first gear is the transmission gear 43. The second gear is fixedly installed on the second cross bar 17.

[0056] Preferably, magnets are built into each link of the chain. The magnets are used to attract the tray 3, so as to adsorb the tray 3 carrying the food 4 on the chain, and make the tray 3 carrying the food 4 move forward following the transmission of the chain.

[0057] Preferably, a plurality of ejecting discs 9 are further arranged on the second cross bar 17. Each ejecting disc 9 is fixedly sleeved on the second cross bar 17 at intervals in parallel, and the distance between the two farthest-spaced ejecting discs 9 is less than the width of the tray 3, so that each ejecting disc 9 can support and eject the tray 3. The height of the ejecting disc 9 is higher than the height of the chain wound around the second cross bar 17, that is, the upper end surface of the ejecting disc 9 is higher than the upper end surface of the chain wound around the second gear, so that the tray 3 on the chain transmitted to near the ejecting disc 9 can be ejected by the top layer disc, so as to take out the tray 3 from the feeding mechanism.

[0058] The sending mechanism includes a roller 7, a conveyor belt 5 and a shovel component. Both ends of the roller 7 are installed on the two radial side ends of the frame 2. The roller 7 is in transmission connection with the driving mechanism, so that the driving mechanism can drive the roller 7 to rotate. Both ends of the conveyor belt 5 are respectively wound around the roller 7 and the shovel component, and rotate under the rotation of the roller 7. The shovel component is installed on the frame 2 and is located at one end close to the feeding mechanism, and the roller 7 is located at one end far from the feeding mechanism. The shovel component and the conveyor belt 5 wound around the position of the shovel component abut against the tray 3 on the feeding mechanism, so that one end of the sending mechanism close to the feeding mechanism abuts against the tray 3, so as to move the food 4 on the tray 3 onto the conveyor belt 5 and move forward following the conveyor belt 5 to be transferred to the next process or removed from the production line.

[0059] Among them, the roller 7 is located above the second cross bar 17, and the roller 7 is located above the side of the first cross bar 8, that is, the height of the roller 7 is higher than the height of the first cross bar 8, and the height of the shovel 53 is between the first cross bar 8 and the second cross bar 17, so that both the feeding mechanism and the sending mechanism are inclined downward towards each other.

[0060] Preferably, the roller 7 is provided with a first thread 71, an annular groove 72 and a second thread 73. The annular groove 72 is arranged at the center of the roller 7. The first thread 71 and the second thread 73 are symmetrically arranged with respect to the annular groove 72, and the helix directions of the first thread 71 and the second thread 73 are exactly opposite. By providing two threads with opposite helix directions, it can effectively prevent the conveyor belt 5 wound around the roller 7 from shifting. The first thread 71, the annular groove 72 and the second thread 73 together play a role in increasing the friction with the conveyor belt 5, so as to prevent the conveyor belt 5 from shifting.

[0061] Preferably, generally, the tray 3 includes a flat tray 3 plate without a surrounding edge and a tray 3 with a surrounding edge. The surrounding edge refers to the side plates that surround the four sides of the tray 3, so that a height difference is formed between the tray 3 and the side plates. In order to enable the blade 53 to still contact the tray 3 even for the tray 3 with a surrounding edge, the blade assembly needs to be set to be angle-adjustable, so that by changing the angle, the end of the blade assembly close to the feeding mechanism can still contact the tray 3 well, facilitating the transfer of the food 4 on the tray 3 onto the blade assembly. The blade assembly is an angle-adjustable blade assembly, and the angle-adjustable blade assembly includes a blade 53, a support plate 47, a second cylinder 48, a telescopic rod 49, a connecting piece 50, a rotating shaft 51, a column 52, a hinge 54 and a connecting plate 55. The blade 53 and the support plate 47 are connected together by the hinge 54, and the upper surfaces of the blade 53 and the support plate 47 are flush, that is, on the same plane. The conveyor belt 5 is wound around one end of the blade 53 away from the support plate 47, and the support plate 47 is installed on the frame 2, thereby installing the blade assembly on the frame 2.

[0062] The second cylinder 48 is fixedly installed below the support plate 47 through the connecting plate 55, and the connecting plate 55 is fixedly attached to the lower surface of the support plate 47 through fixing connectors such as screws. The telescopic rod 49 of the second cylinder 48 is fixedly connected to the connecting piece 50. An activity space 56 with an opening is provided at one end of the connecting piece 50 away from the telescopic rod 49, and a rotating shaft 51 passing through the activity space 56 is provided on the connecting piece 50. The rotating shaft 51 is connected to one end of the column 52, and the column 52 can rotate relative to the rotating shaft 51 within the activity space 56. The other end of the column 52 is fixedly connected to the lower surface of the blade 53.

[0063] When the telescopic rod 49 of the second cylinder 48 extends forward, it drives the connecting piece 50 and the rotating shaft 51 provided on the connecting piece 50 to move forward together, and then drives the column 52 on the rotating shaft 51 to tilt and rotate upward, thereby raising the blade 53. The blade 53 rotates obliquely upward relative to the support plate 47 until the upper surface of the blade 53 is flush with the upper surface of the support plate 47. When the telescopic rod 49 of the cylinder retracts backward, it pulls the connecting piece 50 and the rotating shaft 51 provided on the connecting piece 50 to move backward together, and then pulls the column on the rotating shaft 51 to tilt and rotate downward, thereby lowering the blade 53. The blade 53 rotates obliquely downward relative to the support plate 47, enabling the blade 53 to contact the tray 3 more inclined downward. In the case of a tray 3 with a surrounding edge, the blade 53 can still contact the tray 3 well, so that the food 4 on the tray 3 can be better transferred onto the conveyor belt 5 on the blade 53.

[0064] Preferably, a plurality of hinges 54 are provided, and each hinge 54 extends along the axial direction of the joint between the support plate 47 and the blade 53, and each hinge 54 is arranged in parallel at intervals.

[0065] Preferably, the second cylinder 48 is located at a side close to the pallet 47. The blade 53 includes a transverse portion and a protruding portion. The protruding portion is fixed at the center of the transverse portion and protrudes toward the feeding mechanism, that is, protrudes outward. The column 52 is connected to one side of the transverse portion and is away from the protruding portion. One end of the hinge 54 is fixed to the transverse portion, and the other end is fixed to the pallet 47.

[0066] In order to save materials, a number of hollow openings are provided on the protruding portion, and the hollow openings are arranged in parallel at intervals.

[0067] Preferably, the food 4 demoulding mechanism of the blade 53 further includes a lower support adjustment component and a limit component. The lower support adjustment component is used to adjust the inclination of the blade component and support the blade component. The limit component is used to limit the maximum inclination degree of the blade component after the inclination degree is adjusted by the lower support adjustment component. That is, after the lower surface of the blade component abuts against the limit component, the lower support adjustment component can no longer increase the inclination degree of the blade component and can only be adjusted upward to reduce the inclination degree of the blade component. The lower support adjustment component and the limit component are both fixedly installed on the frame 2 and arranged at intervals. The lower support adjustment component is located at one end of the blade component away from the roller 7, and the limit component is located at one end close to the roller 7.

[0068] The lower support adjustment component includes a first limit wheel, a first rocker arm 30, a first transmission rod 35, a base 34, a bearing 33, a second rocker arm 31, and a first cylinder 32. The first limit wheel is fixedly connected to one side of one end of the first rocker arm 30 close to the blade component, that is, located inside the first rocker arm 30. The other end of the first rocker arm 30 is in transmission connection with the first transmission rod 35, so that the rotation of the first transmission rod 35 can drive the first rocker arm 30 to rotate, thereby adjusting the height of the first limit wheel located on the first rocker arm 30, so that the blade component follows the first limit wheel to tilt downward or tilt upward, thereby adjusting the inclination degree of the blade component. One end of the first transmission rod 35 passing through the base 34 is also in transmission connection with one end of the second rocker arm 31.
