Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a product forming mechanism. Background Technology

[0002] Currently, to meet the position control requirements of positioning turntables, the most mainstream technical solution in the industry is a cylinder-driven shift fork positioning mechanism. This solution uses compressed air to drive the cylinder to extend and retract, causing the shift fork to engage with the positioning groove on the positioning turntable, thereby realizing the start, stop, and positioning of the turntable. Due to its relatively simple structure and low initial investment cost, it is widely used in various automated production lines such as machining and electronic assembly. This mechanism uses compressed air as its power source, and the cylinder's extension and retraction speed depends entirely on the air source pressure. However, in actual production environments, the air source pressure is easily affected by factors such as the air compressor's operating conditions, pipeline losses, and simultaneous air consumption by multiple devices, causing fluctuations. When the air source pressure increases, the cylinder's extension and retraction speed increases sharply, causing the shift fork to collide with the positioning groove at a high speed; when the air source pressure decreases, the cylinder's movement is sluggish, not only prolonging the turntable's rotation cycle and disrupting the production rhythm, but also potentially causing the turntable to jam because the shift fork cannot disengage or become stuck in the positioning groove in time. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned shortcomings, this utility model provides a product forming mechanism, including a turntable mechanism, a positioning disk is installed on the rotating shaft of the turntable mechanism, the positioning disk includes a disk body, and a plurality of V-shaped grooves corresponding to the work positions in the turntable mechanism are opened on the outer peripheral surface of the disk body, and the positioning disk rotates synchronously with the turntable mechanism. The product forming mechanism further includes a limiting mechanism, which includes: Fixing part; An electromagnet, which is fixed on a fixed part; The slider is connected to the fixed part through an elastic element. When the electromagnet is energized, the slider moves radially away from the positioning groove along the positioning plate to compress the elastic element. The limiting part is installed on the upper surface of the slider near the positioning plate. When the electromagnet is de-energized and the V-groove rotates to the preset position, the limiting part cooperates with the V-groove.

[0004] This invention utilizes an electromagnet energized to overcome the force of the elastic element, pulling the slider to disengage the limiting part from the V-groove, thus starting the turntable. After the turntable starts, the electromagnet is briefly energized and then de-energized, allowing the elastic element to push the limiting part against the outer circumference of the positioning plate. Once the target V-groove is in place, positioning is complete. The entire rotation process is responsive and continuous, shortening the turntable rotation cycle and improving overall production efficiency. This invention has a simple structure, reducing common failure points in the pneumatic system such as pipeline leaks and component aging. Furthermore, the electromagnet and elastic element are easy to maintain, eliminating the need for frequent pneumatic system inspections and maintenance, thus reducing long-term maintenance costs and failure rates.

[0005] Furthermore, the limiting part is a roller, which is rotatably mounted on the slider.

[0006] After the electromagnet is de-energized, the roller moves along the outer circumference of the positioning plate and slides into the bottom of the V-groove. During this process, the coefficient of rolling friction is lower than that of sliding friction, which reduces the wear between the limiting part and the positioning plate and the V-groove, reduces the wear of components caused by friction, extends the service life of core components such as rollers and positioning plates, and reduces the replacement cost and maintenance frequency of the equipment.

[0007] Furthermore, the surface of the roller is covered with a cushioning elastic layer.

[0008] When the roller slides into the bottom of the V-groove or comes into contact with the outer circumference of the positioning plate, the elastic layer can absorb the impact force generated by the collision through its own deformation, avoiding the hard impact between the traditional rigid roller and the V-groove and positioning plate. It can effectively buffer the instantaneous impact force and reduce the damage such as dents and scratches caused by the impact on the roller surface, the wall of the V-groove and the outer circumference of the positioning plate.

[0009] Furthermore, a guide hole extending radially along the positioning disc is provided in the fixing part; The limiting mechanism also includes a guide rod, one end of which is connected to the slider, and the other end of which is slidably fitted in the guide hole.

[0010] The guide hole extending radially along the positioning plate inside the fixed part slides with the guide rod, providing strict radial guidance constraint for the movement of the slider, reducing lateral displacement, tilting or jamming of the slider during electromagnet drive or elastic element reset.

[0011] Furthermore, the guide hole is a stepped hole, and the diameter of the stepped hole near the slider end is smaller than the diameter of the stepped hole away from the slider end. The end of the guide rod that mates with the guide hole protrudes outward along its own radial direction to form a limiting flange, which matches the large diameter section of the stepped hole.

[0012] The stepped hole, with its stepped surface created by the difference in hole diameter, mechanically limits the movement of the guide rod by engaging with the limiting flange. As the guide rod moves towards the positioning plate with the slider, the limiting flange, through its indirect engagement with the stepped surface, reduces structural interference caused by the guide rod excessively extending into the guide hole. This also reduces the risk of the guide rod dislodging from the guide hole due to excessive electromagnet pulling force or excessive elastic force, which could lead to the slider impacting the fixed part or excessive compression of the V-groove by the limiting part, thus improving the safety of the mechanism's operation.

[0013] Furthermore, a T-shaped groove is provided on the side of the slider near the fixed part, and the connecting end of the guide rod and the slider matches the T-shaped groove.

[0014] During assembly, no additional fasteners such as bolts and nuts are needed. Simply slide the guide rod connecting end into the T-slot opening and lock it in place to quickly connect the two. During disassembly, simply slide the guide rod in the opposite direction to separate it from the slider. This shortens the assembly time and reduces maintenance difficulty and time costs.

[0015] Furthermore, a limiting piece is provided on the side of the slider parallel to its direction of movement; The limiting mechanism further includes a first limiting sensor and a second limiting sensor, which are arranged opposite to each other, and the limiting piece reciprocates linearly between the first limiting sensor and the second limiting sensor.

[0016] When the electromagnet is energized and drives the slider to move away from the positioning plate, the limit plate moves with the slider, triggering the second limit sensor. The sensor immediately sends a signal to the controller that "the slider has reached the position away from the positioning groove," and the controller can start the turntable. When the electromagnet is de-energized and the elastic element pushes the slider to reset towards the positioning plate, the limit plate triggers the first limit sensor, sending a signal that "the slider has reached the positioning preparation position" or "the limit part has been engaged in the V-groove." The controller can then stop the turntable, improving the positioning accuracy of the turntable station.

[0017] This utility model has the following advantages: This invention utilizes an electromagnet energized to overcome the force of the elastic element, pulling the slider to disengage the limiting part from the V-groove, thus starting the turntable. After the turntable starts, the electromagnet is briefly energized and then de-energized, allowing the elastic element to push the limiting part against the outer circumference of the positioning plate. Once the target V-groove is in place, positioning is complete. The entire rotation process is responsive and continuous, shortening the turntable rotation cycle and improving overall production efficiency. This invention has a simple structure, reducing common failure points in the pneumatic system such as pipeline leaks and component aging. Furthermore, the electromagnet and elastic element are easy to maintain, eliminating the need for frequent pneumatic system inspections and maintenance, thus reducing long-term maintenance costs and failure rates.

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0020] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0021] As described in the background section, in actual production environments, air source pressure is easily affected by factors such as air compressor operating conditions, pipeline losses, and simultaneous air use by multiple devices, resulting in fluctuations. When the air source pressure increases, the cylinder extension and retraction speed increases sharply, causing the shift fork to collide with the positioning groove at a high speed. When the air source pressure decreases, the cylinder action is sluggish, which not only prolongs the turntable rotation cycle and disrupts the production rhythm, but may also cause the turntable to jam because the shift fork cannot disengage or get stuck in the positioning groove in time.

[0022] Example 1: Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a product forming mechanism, such as... Figure 1 As shown, it includes a turntable mechanism 10, on which a positioning disk 20 is mounted, such as... Figure 2 As shown, the positioning disk includes a disk body 21, and a plurality of V-shaped grooves 22 corresponding to the work positions in the turntable mechanism are formed on the outer peripheral surface of the disk body. The positioning disk rotates synchronously with the turntable mechanism. The product forming mechanism also includes a limiting mechanism 30, such as Figure 3 As shown, the limiting mechanism includes: Fixing part 38; Electromagnet 39, which is fixed on the fixing part; The slider 32 is connected to the fixed part through an elastic element 34. When the electromagnet is energized, the slider moves radially away from the positioning groove along the positioning plate to compress the elastic element. The limiting part 33 is installed on the upper surface of the slider near the positioning plate. When the electromagnet is de-energized and the V-groove rotates to the preset position, the limiting part cooperates with the V-groove.

[0023] Specifically, the working principle of this embodiment is as follows: The product forming mechanism is in its initial position, and the turntable mechanism 10 and the positioning disk 20 synchronously connected to its rotating shaft remain stationary. At this time, the electromagnet 39 in the limiting mechanism 30 is de-energized, and the slider 32 moves radially toward the positioning disk 20 under the natural elastic force of the elastic element. This causes the limiting part 33 installed on the upper surface of the slider 32 near the positioning disk to engage in the V-groove 22 corresponding to the station on the outer periphery of the positioning disk 20, thus achieving the initial positioning of the turntable mechanism 10. When the process at the current station is completed and the turntable needs to be rotated, the production line controller sends an energizing signal to the electromagnet 39 of the limiting mechanism 30. After the electromagnet 39 is energized, it generates electromagnetic attraction, which overcomes the elastic force of the elastic element and pulls the slider 32, which is matched with it, to move radially away from the V-groove 22 along the positioning disk 20. During this process, the elastic element is compressed and stores force. As the slider 32 moves, the limiting part 33 mounted on the slider simultaneously disengages from the currently engaged V-groove 22, releasing the limiting constraints on the positioning disk 20 and the turntable mechanism 10. The drive motor of the turntable mechanism 10 starts, and the turntable mechanism 10 drives the positioning disk 20 to begin rotating synchronously, entering the indexing stage. The electromagnet 39 remains briefly energized after the turntable starts, maintaining the disengaged position of the slider 32. After the turntable mechanism 10 drives the positioning disk 20 to rotate, the controller sends a de-energization signal to the electromagnet 39, and the electromagnetic attraction of the electromagnet 39 disappears. At this time, the compressed elastic element releases its stored force, pushing the slider 32 to reset radially towards the outer circumference of the positioning disk 20. The slider 32 drives the limiting part 33 to move synchronously until the limiting part 33 contacts the outer circumference of the positioning disk 20. During this stage, the limiting part 33 remains in contact with the outer circumference of the positioning disk 20 under the continuous pressure of the elastic element, and is in a positioning state. When the positioning disk 20 rotates to the preset position of the V-groove 22 corresponding to the target workstation, which is close to the limiting part 33, under the pressure of the elastic element, the limiting part 33 automatically slides into the bottom of the groove along the inclined surface of the V-groove 22 and locks in place, thus limiting the positioning disk 20. After the positioning disk 20 is limited, it synchronously drives the turntable mechanism 10 to stop rotating, and the target workstation corresponds to the processing or assembly position, repeating this process. In this embodiment, the limiting mechanism also includes a mounting plate 31, which can be fixed to the mounting structure of the turntable mechanism for mounting on the frame. The slider can be slidably mounted on the mounting plate through the guide structure, and the fixing part is fixed to one side of the mounting plate.

[0024] In this embodiment, an electromagnet is energized to overcome the force of the elastic element, pulling the slider to disengage the limiting part from the V-groove, thus starting the turntable. After the turntable starts, the electromagnet is briefly energized and then de-energized, allowing the elastic element to push the limiting part against the outer circumference of the positioning plate. Once the target V-groove is in place, positioning is completed. The entire rotation process is responsive and continuous, shortening the turntable rotation cycle and improving overall production efficiency. This invention has a simple structure, reducing common failure points in the pneumatic system such as pipeline leaks and component aging. Furthermore, the electromagnet and elastic element are easy to maintain, eliminating the need for frequent pneumatic system inspections and maintenance, thus reducing long-term maintenance costs and failure rates.

[0025] In this embodiment, the limiting part can be a roller, which is rotatably mounted on the slider.

[0026] After the electromagnet is de-energized, the roller moves along the outer circumference of the positioning plate and slides into the bottom of the V-groove. During this process, the coefficient of rolling friction is lower than that of sliding friction, which reduces the wear between the limiting part and the positioning plate and the V-groove, reduces the wear of components caused by friction, extends the service life of core components such as rollers and positioning plates, and reduces the replacement cost and maintenance frequency of the equipment.

[0027] Preferably, a cushioning elastic layer may also be covered on the surface of the roller.

[0028] When the roller slides into the bottom of the V-groove or comes into contact with the outer circumference of the positioning plate, the elastic layer can absorb the impact force generated by the collision through its own deformation, avoiding the hard impact between the traditional rigid roller and the V-groove and positioning plate. It can effectively buffer the instantaneous impact force and reduce the damage such as dents and scratches caused by the impact on the roller surface, the wall of the V-groove and the outer circumference of the positioning plate.

[0029] In this embodiment, as Figure 5 As shown, a guide hole 38A extending radially along the positioning plate is provided in the fixing part; The limiting mechanism also includes a guide rod 36, one end of which is connected to the slider, and the other end is slidably fitted in the guide hole.

[0030] The guide hole extending radially along the positioning plate inside the fixed part slides with the guide rod, providing strict radial guidance constraint for the movement of the slider, reducing lateral displacement, tilting or jamming of the slider during electromagnet drive or elastic element reset.

[0031] In this embodiment, the guide hole is a stepped hole, and the diameter of the stepped hole near the slider end is smaller than the diameter of the stepped hole away from the slider end; The end of the guide rod that mates with the guide hole protrudes outward along its own radial direction to form a limiting flange, which matches the large diameter section of the stepped hole.

[0032] The stepped hole, with its stepped surface created by the difference in hole diameter, forms a mechanical limiting engagement with the limiting flange of the guide rod. When the guide rod moves towards the positioning plate with the slider (pushed back by the elastic element), the limiting flange, through indirect engagement with the stepped surface (or synergistic action with the slider), reduces structural interference caused by the guide rod excessively extending into the guide hole. This reduces the risk of the guide rod dislodging from the guide hole due to excessive electromagnet pulling force or excessive elastic element pushing force, leading to excessive displacement issues such as the slider hitting the fixed part or the limiting part (roller) excessively squeezing the V-groove, thus improving the operational safety of the mechanism.

[0033] In this embodiment, as Figure 4 As shown, a T-shaped groove 32B is provided on the side of the slider near the fixed part, and the connecting end of the guide rod and the slider matches the T-shaped groove.

[0034] During assembly, no additional fasteners such as bolts and nuts are needed. Simply slide the guide rod connecting end into the T-slot opening and lock it in place to quickly connect the two. During disassembly, simply slide the guide rod in the opposite direction to separate it from the slider. This shortens the assembly time and reduces maintenance difficulty and time costs.

[0035] In this embodiment, a limiting piece 32A is provided on the side of the slider parallel to its direction of movement; The limiting mechanism further includes a first limiting sensor 35 and a second limiting sensor 37, which are arranged opposite to each other, and the limiting piece reciprocates linearly between the first limiting sensor and the second limiting sensor.

[0036] When the electromagnet is energized and drives the slider to move away from the positioning plate, the limit plate moves with the slider, triggering the second limit sensor (away from the positioning plate). The sensor immediately sends a signal to the controller that "the slider has reached the position away from the positioning groove," and the controller can start the turntable. When the electromagnet is de-energized and the elastic element pushes the slider to reset towards the positioning plate, the limit plate triggers the first limit sensor (near the positioning plate), sending a signal that "the slider has reached the positioning preparation position" or "the limit part has been engaged in the V-groove." The controller can then stop the turntable, improving the positioning accuracy of the turntable station.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
